Due to ever tightening federal EPA requirements, today’s motor oils have reduced quantities of anti-wear chemistries like Zinc, Phosphorus and Sulfur. As a result, the oil you buy today is not the same as it was 10 years ago. While this is good for most stock daily driven street cars, it is bad news for your racing engine. Racing engines see more RPM, higher loads and increased temperatures compared to street engines, so a racing engine requires higher levels of these wear additives to prevent premature part failure. So you see, the oil used in an engine needs to be formulated specifically for that type of engine. You wouldn’t use a stock piston in a race engine, and the same goes for oil. And that’s where Driven excels.

Driven Is

Different If you think all oil performs and protects the same then you would be mistaken. Driven Racing Oil’s Lubrication Specialist Lake Speed, Jr. tells us just how different Driven Racing Oil is.

A

ccording to Speed, “the last thing the world needs is another oil company” and “there’s no such thing as the best oil.” Strange words coming from a man who has devoted his entire career to just that – oil. But this devotion also makes him understand that “best oil” isn’t actually the principle – it’s the “right oil.” Driven Racing Oil was originally created to advance engine and driveline lubricant performance in all-out race and high performance engines, but now those innovations extend beyond the racetrack to the street.

The product line is unique in that it “puts the motor ahead of the molecule.” Often oil companies have no real world understanding of how these products are actually used, but Driven keeps things in the proper order. The oil is for the motor, not the other way around. The product development team looks at the motor and how it is used; then they design application specific products using a “zero compromise” approach that delivers a measurable performance advantage.

Lake Speed, Jr. Explains Why “Driven Is Different.” Does racing R&D transfer to the average Joe on the street? What we learn in racing we do apply across the board – we the take basic chemistry from the toughest race environment and apply it to street performance.

You’re a small company – how are you able to compete with the big name companies? The small company size allows us to be nimble and deal directly with the end user. When you call Driven, you talk to the head tech guy, not a mid-level customer service person who didn’t actually formulate the product. And our products are used at the highest levels of motorsports all the way back to the guy in his garage.

What does the future hold for Driven? We stay in constant communication with the end user to stay on top of an ever evolving market. So, armed with that information, we’ll then use chemical engineering to enable higher performance, better fuel economy and lower emissions across the spectrum of vehicles. This will also help us develop more advanced technology to bring to the table. Performance enthusiasts will always push the envelope – we’ll help push them to that next step.

Rocker ArmS O

ne of the most important components in your engine is the rocker arm. It is also one of the most vulnerable. As the turning point of the valve train, the rocker arm is basically a sophisticated lever that redirects the upward tappet and pushrod movement and then multiplies it by the rocker ratio to downward movement at the valve.

Aluminum Rockers

Until recently, aluminum rocker arms have been considered a more affordable but less durable option to steel rockers. COMP Cams has developed aluminum rockers that use precision-sorted needle bearing trunnions to withstand both aggressive spring pressures and valve lift. The COMP Cams Ultra-Gold ARC Aluminum Roller Rockers actually have the highest rocker-to-valve spring clearance of any aluminum rocker – up to 1.625" valve spring O.D. And while these aluminum rockers are lightweight, they are still incredibly strong and feature a lifetime warranty.

Make the rocker arm stiffer  To increase stiffness, look at three characteristics: material, geometry and the rocker’s holding fixture. The easiest way to increase stiffness is to switch to chromemoly steel. Although heavier than some other materials, it can offer some design advantages and have much thinner sections than aluminum due to its superior strength density. Stiffness of the mounting is just as important as the stiffness of the rocker body. For the ultimate in high performance, shaft mounted rockers may be the way to go.

Steel Rockers

COMP Cams steel rocker arms are all constructed from 8620 or 8650 chromemoly steel, which is a higher grade material that makes them extremely durable and tough. The material keeps them from flexing, and they have large trunnions and more needle bearings, which allow the load to be more evenly spread and the rocker to last longer. Steel can thus be run in harsh environments without fatigue issues. Some COMP steel rockers are even lighter than most aluminum because COMP has reduced mass in low stress areas.

Decrease the moment of inertia  The moment of inertia is the rocker’s resistance to rotation. The higher this measurement, the more valve spring pressure it takes to control the rocker arm instead of the valves – losing RPM and horsepower. The moment of inertia is lowered by lightening the rocker arm’s weight, particularly at areas that are farther from the trunnion. Two ways you can do this are by switching to a lighter weight material or by removing mass from the rocker body design.

stud/Shaft mounted

Three Basic Ways To Increase Power Through A Rocker Arm Change

This is a highly critical process. Due to stresses and vibrations, which are more prevalent during high speed operation, rocker arms undergo what is known as deflection. Severe rocker arm deflection causes inefficient engine performance, and often results in metal fatigue leading to increased wear and friction in the valve train and eventually engine failure.

1 2

Lift the valve more  By increasing the rocker arm ratio, it’s possible to increase valve lift without ever touching the camshaft. Valve lift can typically be increased as much as 10% by increasing rocker ratio.

3

Stud mounted rockers have evolved over the years, resulting in geometric design changes that led to the innovative arched web design seen in today’s Ultra Pro Magnum and Ultra Pro Magnum XD Rockers from COMP Cams. Shaft mounted rockers have increased mounting stiffness and valve train stability. These systems are designed for high-end performance applications.

Universal Engine Swap?

GM’s LS-based engines are the most popular engine swaps today with muscle car and hot rod car builders. So what makes them so popular?

W

hen the first LS engine appeared in the 1997 Corvette, it left traditional Chevy engine fans scratching their heads. Here was an engine that rewrote all of the rules with virtually nothing that interchanged into the classic Small Block Chevy launched way back in 1955. Some doubted its staying power. But engine builders took a wait-and-see mentality to determine if the aftermarket would embrace this new engine.

As we all know now, the LS family of engines has grown dramatically. Its versatility to make power and torque with new and uniquely LSbased components has changed the way racers and enthusiasts race and drive their vehicles. Today it has become the preferred “resto-mod” engine for a number of reasons.

Top reasons to go LS Great durability: The LS engine has better sealing characteristics than either the classic Chevy small or big

block engines. This includes not only the oiling systems, which were tragically flawed with the classics, but with head gaskets which have better cylinder and water jacket sealing.

Easily adaptable:  As the engine has evolved, both the factory and the aftermarket have created new ways to make power. Whether you are using the steel block truck LS base (which is highly available, sturdy and inexpensive) all the way to the LS9, you can swap from a wide range of heads and cranks along with naturally aspirated intakes, superchargers or turbo systems. The number of aftermarket components available from intake

4. Each main bearing cap features six bolts 5. The block bore spacing on all engines is 4.40" 6. Lifter bores measure 0.842" in diameter manifolds to off-the-shelf and custom ground camshafts make just about any performance target reachable.

Easy power: While the newest LS9 engine makes up to 638 horsepower and tons of torque, aftermarket changes can net far more power. This slim dimensioned engine (have you measured the Ford Coyote engine valve cover width?) will fit in a wide variety of engine bays. But the key is the ease with which power adder parts can be bolted in place. Just take a surf for online products through the Summit (www.summitracing. com) or Jegs (www.jegs.com) websites for some happy results.

Emissions compatible: GM started early in the game of building engine “packages,” making it easy for enthusiasts not wishing to battle emissions regulations. LS engine buyers will find it easy to build up an engine that features excellent drivability through modern car-style fuel injection and full emissions legality.

Engine Swap Kits There are a wide variety of engine swap kits available that allow easy installation of your LS engine into many classic domestic and assorted import vehicles. They offer hard-to-find parts, such as oil pans, that are compatible with the OEM tie rods and K-members, remote air intake systems that sidestep the need for modifying stock hoods and complete electronic fuel injection wiring retro-fits to replace classic carbureted engines with modern fuel injection. Your best guide here are LS forums such as LS1Tech.com. The possibilities will amaze you.

Camaro

LS power & modern day suspension make this classic muscle car 100% cool Photos by Norm Brandes & Joe Lewandowski

Carl Schultz had a ’69 Camaro. It was a clean, very straight, old restoration with classic drivetrain but in need of new power and suspension. With dreams of a more modern and efficient muscle car, Carl met with Norm Brandes and Jim Daley from Silver Lake, Wisconsin’s Westech Automotive at the 2012 Performance Racing Industry show in Orlando. Shortly thereafter, a complete Camaro ready for performance upgrades showed up at the Westech Shop. After serious discussions among all involved about potential forms of LS engine transplants, Carl, owner of Five Star Racing Bodies, settled on a new GM Performance LSX454 engine cranking out over 620 horsepower. Adding to that total, Westech Automotive added a FAST LSXR Intake with a Big Mouth Throttle Body to build upon the impressive power.

This Camaro fools the competition by packing a 620 HP LSX454 engine under the hood.

LS Performance

While original plans called for a 200R4 automatic transmission to replace the apparent factory 350TH currently in the car, a total redirection was ultimately made, inserting a Tremec TKO six-speed after it was determined that the original fitment was for a 4-speed manual transmission. To ensure pos-


itive tire engagement, a heavy-duty clutch plus a strong and lightweight driveshaft were installed to control the massive horsepower and torque. To improve the drivability of the car, Westech engineered a throttle-by-cable fuel injection system over the more common throttle-by-wire controls typically found with this engine. The spark plug coil packs were mounted by the oil pan to keep all wiring out of view and the plumbing was contained with stainless steel tubing, making for a super clean engine compartment. But it was clear to both Norm and Jim at Westech, along with Carl, that the car had to stop and handle as well as a new Camaro. Happy with the modifications made to modernize the power and throttle response, they turned to the suspension. To get the right handling and chassis strength, they called on Heidts Hot Rods and Muscle Cars of Lake Zurich, Illinois, to achieve those key features. In the rear they installed a Heidts four-link suspension — two inches narrower than stock — to accommo-

date the increased width wheels and tires they had planned. Up front, they used the Heidts Pro-G subframe featuring rack-and-pinion steering for crisp cornering and excellent steering response. Massive diameter Wilwood disc brake rotors accompanied with six-piston front and four-piston rear calipers netted better than a modern car stopping power. Finishing off the Camaro, Norm and Jim attended to some of the spots on the paint needing touch-up but for the

most part left the exterior as it arrived. To that they added SS-style graphics and the original 350 c.i. engine emblems to fool the competition as to the amazing power under the hood. The result is a car that checks all the boxes with regards to modern Camaro performance while wrapped in one of the best Camaro shapes ever to leave a GM assembly line.

Conical Valve Springs Expected to become the new standard in high performance valve spring design, COMP Cams Conical Valve Springs utilize a round wire and feature a diameter and progressive pitch driven natural frequency. The conical shape constantly decreases diameter from the bottom to top to reduce active mass and decrease applied forces, which results in longer valve train component life and less parasitic horsepower loss. This design also increases the valve train RPM limit while reducing resonance concerns and decreasing dynamic spring oscillations. It dampens without wear, heat/friction or risk from interference contact. The result is longer spring life and the ability to run more aggressive camshafts. Superfinish surface processing also increases both lift capability and spring longevity.

TIMING IT RIGHT Cam Phaser Limiter Kits (Patent 8,291,876 B2) Cam phasers are computer-controlled cam gears that automatically optimize cam timing based on current engine RPM and are used in 2007+ GM Gen IV VVT (Variable Valve Timing) engines. Engine oil is pressure-fed to the phasers through passageways in the cylinder heads and cams. The engine computers control solenoids that adjust this oil flow throughout the phasers’ control chambers, creating the ability to retard the cams.

wide range of valve timing movement, there is very little piston-to-valve clearance, which limits you to small cam profiles with little overlap. COMP Cams Cam Phaser Limiter Kits restrict the range of cam timing movement to 22°, thereby providing the necessary valve clearance for serious performance cams with tighter lobe separations – all while utilizing the benefits of VVT technology. Starting at $64.22.

While this technology provides fuel efficiency and the ability to always be in the best position for maximum power, regardless of engine RPM, it presents some limits when it comes to performance cams. With such a

1LE FranZ’s

RED HOT

A 2013 Camaro 1LE With Mods To Make Sure It Lights Up The Competition Story & Photos By ChevyHardcore.com

In 2013, Chevrolet released the 1LE package for Camaros. This package was an upgrade from the SS package that offered an affordable alternative with many of the ZL1’s upgrades, but didn’t have the supercharger bolted to the motor. Many aspects made the transition though, such as the blacked out hood, upgraded suspension and suede appointed interior. Our shop can get extremely backed up with project cars, so having a local shop that specializes in late-model GMs is a valuable asset. When it comes to GM cars, our partner to help with the work load is Cunningham Motorsports, in Murrieta, CA. CMS specializes in tuning and tweaking GM cars. One day when we were at CMS, we noticed a brand new, shiny red Camaro SS 1LE sitting out front and had to know what the story was behind the car. Ryne Cunningham the owner of Cunningham Motorsports, said the Camaro was his personal ride. We chatted with him about the car, but not much else was said about it. However, over the course of a year we noticed that the Camaro was receiving upgrades. CMS had to put their touches on the car to make sure that the Camaro reached its full potential.

Acquiring The 1LE We asked Ryne what caught his eye about the 1LE Camaro, besides the bright red paint. “For me it was the price point. I was able to get an SS Camaro, with a ton of upgrades for a great price.” His plans were to take the car to the occasional road race, but mainly drive it daily. The plan was never to leave the Camaro in stock form though.

Starting Modifications Showing what CMS was capable of, they started by installing a set of American Racing headers to help free up some horsepower. These headers are 100% American made from stainless steel. According to their website, just bolting on these headers will provide an extra 32 WHP, without a tune. From there he ordered up one of his own custom ground COMP Cams. These cams are specifically ground to CMS specifications. With this cam, the motor has a nice lope to it but is still street able and tame. Being a proprietary CMS product, Ryne wouldn’t give us the exact specs. After the new bump stick was installed, a cold air Airaid intake was installed. After all these modifications were complete, the car was thrown on the dyno to see what it could do. What Ryne walked away with was an impressive 432 lb. ft. of torque and 472 HP, at the wheels.

Suspension Upgrades Turning his attention from the engine, Ryne looked at the suspension. Even though this car had the upgraded 1LE suspension, he knew there was more potential in the Camaro to make the car handle flawlessly on the track. What he did was replace the stock sway bars for a set of high performance Pfadt sway bars in the front and rear to keep the car planted. While he was tinkering with the suspension, a set of Pfadt drop springs were thrown in to get the stance on the car just right and lower the center of gravity. In the rear, a set of Pfadt cradle bushings were added as well, to keep the rear end in the right spot and prevent any driveline vibrations. Now that the car had the right stance, a new set of wheels was in order to finish off the menacing look of the car. Cunningham called Forgeline to get a set of wheels for the car. In the front he opted for a set of 20×10.5" GA3’s and a set of 20×11.5" for the rear. The GA3 wheels are worth noting as well as these aren’t just a fancy set of wheels. Forgeline used all of their racing knowledge to produce this street version of their race GA3R wheel. They are made from 6061-T3 aluminum with heat-treated rim shells and assembled with stainless steel hardware. The “I-Beam” technology reduces weight in the wheel but provides extra strength. With custom finishes available from Forgeline, Cunningham picked a gloss black hoop with contrasting flat black spokes for a dramatic look. They are wrapped in a sticky set of BF Goodwrich Rivals, 285/35/R20 in the front and 315/30/R20 in the rear to keep the car stuck to the ground like glue. 28

Testing The Limits Once all the mods had been done, Ryne wanted to really test the car out. “I took the car on a half mile airport strip and did 147 mph, hitting the rev limiter.” That just tells us the car has more in it for a higher speed, but the car wasn’t built for that. “I also took the car to Big Willow Springs, where I ran the course in 1:34.4,” he added. Big Willow, in Rosamond, CA, is a 2.5 mile road course located two and a half hours north of Cunningham Motorsports. Looking at the Big Willow track records, we see Mario Andretti holds the record at 1:06.050 seconds in an Indy Car. Cunningham’s record is pretty impressive for a car three times the size and weight of the track record holder.

Selling The 1LE As is the case with many gearheads, when the car was “finished” Ryne got bored with it with only 7,200 miles on the odometer. He decided to sell off the car to help finance the next project. We asked him what happened to his red hot ride and he pointed to his right-hand man in the shop, Mike Franz. When Ryne decided that he was ready for that next project, he started asking around if anybody was interested in the 1LE. Mike raised his hand saying he would love to buy the car. A deal was struck and the car now resides with Mike.

New Ownership Mike is a Chevy man through and through. This 1LE Camaro is actually the fifth Camaro he has owned. “I grew up in a Chevy family, so I was raised around Chevys” he explained. After test driving a Dodge Challenger and Ford Mustang, Mike knew the Camaro was the car he wanted. “For me these 5th Gen Camaros were the fastest, most comfortable, with a back seat and in my price range.”

We asked Mike what he really loved about the car. “I’m the bully at the stoplight” he said laughing. “I have a car that catches eyes but has the power to back it up.” Even though he’s not a big fan of red cars, something just drew Mike to this particular Camaro. “I was just drawn to the red on this car, plus I’m the one that turned all the wrenches on this Camaro at CMS, so I knew it well.” Since all the upgrades had been done with the car, Mike said he hasn’t really made any major modifications to the car since it’s been in his possession. The few modifications that Mike did to help make the car his own was to add a pair of ten-inch Rockford Fosgate subwoofers in the trunk for a little bass. Since he also worked at CMS, he couldn’t just leave the car alone. He figured out how to control the two stage mufflers with a remote control. Now he can push a button and go from stealth mode to race mode and back again. A neat little trick to have in your pocket, especially if the police are sitting behind you at a light.

Future Plans We noticed that Mike really babies this car when cruising around. Being big gearheads we would want to constantly mash the throttle. “This car is my daily driver that I rely on to get to work and back, so I try to not beat it up too much,” he said. He does have plans to take it down the drag strip to see what the car can do though. “I don’t really want to take it on a road course because that beats up cars pretty good, and I still have to make it to work on Monday.” When talking about the car, Mike has nothing but a huge smile on his face. He said that he drives the car everywhere, in any weather. There’s nothing wrong with daily driving a super car, except trying to keep your foot off the gas. Cunningham Motorsports  951.677.0716

How To Choose Your Precision-Flow Fuel Injectors 1. Take your target peak horsepower and multiply by ••.5 for naturally aspirated ••.6 for supercharged ••.625 for turbocharged 2. Take that figure and divide by the number of cylinders. 3. Divide by .9 (for 90% duty cycle). This will give you the lb./hr. you will need from each injector. Example: 520 horsepower, naturally aspirated V8 (520 x .5=260), (260/8=32.5), (32.5/.9=36) This application would require 36 lb./hr. Precision-Flow Fuel Injectors (Part #303600). If the formula gives you a number that is not one of the injector sizes, the general rule is to move up to the next largest size. Description

Fuel Injector Adapter Harnesses & Connector Kits FAST Fuel Injector Adapter Harnesses and Connector Kits enable easy retro-fitting of both new and old style electronic fuel injectors. New style fuel injectors can be used on vehicles equipped with older-style minitimer connectors.

span. They also utilize bearings that increase thrust capacity and reduce drag, as well as turbine spline reinforcement welds for increased durability and a heat-treated steel hub that increases converter strength. TCI employs a highly specialized production process that ensures each unit is built to spec. Regardless of the category or price level in which a TCI torque converters falls, rest assured that it has been Triple Tested during assembly.

Torque Converters Explained Impeller Pump  The impeller pump is the outside half of the converter on the transmission side of the weld line. Inside the impeller pump is a series of longitudinal fins that drive the fluid around the outside diameter into the turbine because this component is welded to the cover, which is bolted to the flexplate. The size of the torque converter (and pump) and the number and shape of the fins all affect the characteristics of the converter. If long torque converter life is an objective, it is extremely important that the fins of the impeller pump are adequately reinforced against fatigue and the outside housing does not distort under stress. Stator  The stator can be described as the “brain” of the torque converter, although it is not the sole determiner of converter function and characteristics. The stator, which changes fluid flow between the turbine and pump, is what makes a torque converter a converter (multiplier) and not strictly a fluid coupler. With the stator removed a converter will retain none of its torque multiplying effect. Turbine  The turbine rides within the cover and is attached to the drivetrain via a spline fit to the input shaft of the transmission. When the turbine moves, the car moves. Cover  The cover (also referred to as the front) is the outside half of the housing that faces toward the engine side from the weld line. The cover serves to attach the converter to the flexplate (engine) and contains the fluid. While the cover is not actively involved in the characteristics of performance, it is important that the cover remain rigid under stress (torsional and thrust stress as well as the tremendous hydraulic pressure generated by the torque converter internally).

TCI employs a highly specialized production process that involves ensuring that each unit is built to spec. Regardless of the category or price level in which a TCI torque converters falls, you can rest assured that it has been Triple Tested during assembly. Once all prep work on the component parts has been completed, the impeller is welded to the front cover. Immediately following this process, a pair of dial indicators is employed on a rotating table to verify that the impeller body and pump drive hub remain true. Each unit is then pressurized and subjected to a leak test to confirm the integrity of all weld seams. Last, each unit is computer balanced to reduce annoying and potentially damaging drivetrain vibrations that can occur from an unbalanced torque converter. That's triple tested so you can be confident you are receiving the perfect torque converter for your specific application.

Frequently Asked Questions About TCI Torque Converters With an automatic transmission, a torque converter is chosen by its stall speed. Select a torque converter with a stall speed 300 to 400 RPM higher than the peak torque output of your engine if you are using a transbrake. Below are some other frequently asked questions about torque converter stall. What is stall speed? Stall speed is the RPM that a given torque converter (impeller) must spin in order for it to overcome a given amount of load and begin moving the turbine. What are the differences between flash stall and brake stall? Flash stall is the true stall of a torque converter. Brake stall, or “foot brake stall,” is the RPM that occurs when the engine overrides the brake system, and the car begins to “push” forward.

•• 1000+ RPM increase in stall over stock •• Efficient at highway cruising speeds and harder launches at wide-open throttle •• Bolt-in with no modifications required •• Designed for moderately modified street machines and weekend racers used as daily drivers 42

LS Performance

Which one is the more effective measurement of the two? Brake stall is NOT an accurate way to properly check the stall because there are too many variables that affect it. When measuring the stall of your torque converter, the flash stall will always be the more effective option of the two.

PERFORM YOUR OWN STALL CHANGES AT HOME Furnace Brazed Fins Provide Increased Strength

Bolt-Together Front Cover Allows For Easy Stall Changes & Service Of Frictions & Bearings By User

Bolt-Together Torque Converters Built specifically for the punishing enviroments of high horsepower LS engines. TCI engineers have developed a complete line of bolt-together converters for the 4L60E and 6L80 transmissions from GM. These converters feature an increase in stall speed over stock options, thereby increasing torque multiplication and allowing the engine to get into its powerband sooner. The result is improved vehicle launch and overall performance. They are designed for extreme power, easy stall speed changes and consistent performance.

High Torque Capacity Triple Disc Lock-Up Clutch Features Race-Quality Friction Material

Billet Cover For Ultimate Durability

Benefits include a triple-disc clutch with significantly higher torque capacity and much higher clamping force than a single-disc design, while they also have the ability to fully lock-up under wide open throttle so there is little or no high-gear slippage. These converters are can be used in many high horsepower and modified vehicles when a single-disc converter simply won’t withstand the power. Featured along with the high torque capacity, triple-disc, woven carbon fiber friction lock-up clutch is a 50-spline clutch hub, meaning the horsepower capacity of this converter is second to none. And thanks to the bolt-together design, stall changes and service of frictions and bearings can be performed at home. Starting at $921.82, depending on application and stall speed. * The race version of the 6L80 requires a custom tuned TCU/PCM, but the street version does not require tuning.

A Whole New

Another Randy Johnson Knows How To Cut Down the Competition He isn’t the former Major League Baseball pitcher known for 100-mph fastballs, but this particular Randy Johnson can still bring the heat in his second-gen Camaro. Randy Johnson is certainly familiar with second generation F-body Camaros. Owner of D & Z Customs in Kewaskum, Wisconsin, Randy had been a regular in the winner’s circle for years, making this generation of Camaro more popular with autocross and road racing fans at every turn. Randy already had experience building a successful second gen Camaro

that taught him plenty about how to build a hot corner-turning machine. He had even collected an assortment of trophies with this Camaro in its orange color scheme so he decided it was time to make a color change and step up his game. Randy’s green machine is powered by a 680 HP Wegner Automotive LS7 outfit with Wiseco 11:1 compression pistons linked to Callies connecting rods and crankshaft. COMP pushrods, roller lifters and a custom ground camshaft are hidden under the RHS LS7 cylinder heads and FAST 102mm LSXR intake manifold.

To keep the fuel flowing, Randy installed FAST 52 lb./hr. injectors and a GM ZL1 fuel pump. The LS7 features a Dailey Engineering dry-sump oiling system and a Peterson Fluid Systems 10-quart tank. Two-row radiator hands and a C&R Racing oil cooler further engine cooling. Stainless Works handles the exhaust system and delivers what has to be labeled as an “angry” exhaust note. Up front Randy installed the Heidts Pro-G suspension that included the Heidts prototype cantilever suspension system bolstered by RideTech triple-adjustable shocks. To get the

correct ride height, Heidts Pro-G 2" drop spindles and tubular lower A-Arms were bolted in place. In the rear, Randy kept it Heidts-pure, including a new Heidts Pro-G independent rear suspension. Added to that elaborate IRS suspension system, he used RideTech springs and, again, triple-adjustable coil-over shocks. Handling the intense and repetitive braking Randy would encounter in racing situations, he installed massive Wilwood W6A six-piston calipers and 14" GT slotted rotors to the front Heidts suspension. In the rear, Wilwood Dyna-Pro four-piston calipers to clamp down on the 10.25" diameter rotors – both front and rear systems proving more than capable to stop the awesome green Camaro. To hold tight to the track surface, Nitto NT05 tires measuring 295/35-18 in the front and 335/30-19 in the rear are wrapped around powder coated black outer hoop with gunmetal grey centered (and center-locking) Forgeline DE3C wheels (18 x 10 front and 19 x 12 rear). An often overlooked handling bonus is the RideTech fivepoint seat harness that mounts to the RideTech tiger cage, significantly increasing the structure of the car and further aiding corner carving. Watch for Randy to take this slick green machine to the winner’s circle in autocross and street racing series.

KING

of LS Blocks

The RHS block, designed for radical street and all-out racing applications, is a proven foundation for building real LS performance. Going beyond the limitations of other GM LS blocks, the RHS LS Race Block is available in both standard (9.240") and tall (9.750") deck height combinations and is engineered for maximum clearance around a 4.600" stroke crankshaft. This was done by raising the camshaft centerline (.388"/9.86mm) and including priority main oiling that shifts the oil galley outboard. With this unique design, RHS engineers also minimized windage in the rotating assembly – leading to superior engine lubrication at higher RPM.

56

LS Performance

To make it friendly for existing race applications, the block contains both factory and motor plate race mounts for Gen I, II, III and IV engines. And for quality assurance, RHS conducts a CT scan (similar to a medical CAT scan) on each block to ensure maximum precision and consistency. Combine that with more standard features than any block on the market and the RHS LS Race Block becomes the benchmark of LS power, strength and compatibility for radical street and all-out racing applications. Starting at $4,979.84.

ZEX Lets Talk ABOUT

Debunking The Myths of Nitrous Oxide

While there has never been any question as to the wonderful power inducing performance gained by injecting nitrous oxide into your engine, it has also been surrounded by some serious misconceptions. So we’re here to clear the air. The following are what we believe to be the top three myths about nitrous injection and its effects on your engine. Myth #1: Nitrous will blow up my engine! Simply stated, nitrous, when properly installed according to the manufacturer’s instructions, will NOT blow up your engine. Nitrous is still the easiest and safest way to greatly increase your engine’s horsepower. Problems arise when people realize how easy it is to significantly increase engine power. With today’s modern nitrous systems, all that is required is approximately two minutes to change the nitrous and fuel jets, which can add an additional 50, 100, even 300 horsepower. Beginners often try to push the window, figuring if everything appears to be running well, a “little” more nitrous can’t hurt their engine. But, novice nitrous users forget to make the proper (and safe) engine ad60

LS Performance

justments in accordance with the increased nitrous jet sizing. The most commonly overlooked adjustments include forgetting to retard the ignition timing, not changing to “colder” heat range spark plugs, and in some cases, not installing an increased flow capacity fuel pump to deliver sufficient fuel flow. The result is a nitrous system that is not correctly installed for safe operation, making engine damage inevitable. As long as the installer follows the manufacturer’s tuning instructions and advice with regard to engine adjustments and vehicle upgrades, they will have safe, reliable power gains that will not harm their engine in any way.

All ZEX Systems incLUDE: Fuel Shear Technology

ZEX Fuel Shear Technology injects enrichment fuel using a fuel transfer tube. The tube allows the nozzle to directly inject fuel into the highest velocity area of the nitrous plume. This high-speed nitrous shears the fuel away from the tube, atomizing it to levels other nozzle designs never achieve. This ensures perfect fuel distribution from cylinder to cylinder. The finely atomized mixture also burns more powerfully and maximizes the horsepower you get from your nitrous system.

Active Fuel Control Technology

In your engine, a vacuum is created as nitrous gas is sprayed across the open end of the nozzle’s fuel transfer tube. As bottle pressure rises or lowers due to bottle temperature changes, the speed of the nitrous discharge varies to the same degree. This causes the level of vacuum draw in the fuel transfer tube to vary as well. This variable vacuum draw causes the nozzle to “pull” more or less enrichment fuel into the engine. This means your engine never runs too lean or too rich. The nitrous tune-up stays dead-on for maximum engine safety and power at all times.

TPS Sensor

For optimum safety, every ZEX kit features a patented TPS switch to activate the nitrous system only at wide-open throttle. It is fully compatible with throttle-by-wire engines.


Myth #2: Blowers & turbos are safer than nitrous injection. A properly installed nitrous system offers virtually the same level of engine safety as supercharger and turbocharger enhancements. Forced induction engine kits are most commonly complete packages that include fuel system and computer tuning upgrades. This allows the manufacturer to build a safe computer “tune-up” into the system they provide. But adding all of those extras raises the cost of the upgrade by thousands of dollars. With a nitrous system, the manufacturer provides precisely what is required to safely use nitrous, as well as detailed recommendations when fuel and ignition upgrades are necessary. The beauty of this information is that the customer makes the decision as to how far they can go with their nitrous system based on their specific upgrades. A person spraying a 75 HP shot of nitrous doesn’t require a fuel pump upgrade, so why should he or she pay extra for one? But a person that wants to spray a 200 HP shot will definitely need to increase the fuel flow as well as the ignition system performance. When it comes down to it, a nitrous system is just as safe as a blower or turbo kit as long as it’s installed with the fuel and ignition system upgrades needed for the power level you wish to run.

Myth #3: Nitrous oxide is the same thing as nitro methane. Nitrous oxide and nitro methane are NOT the same thing – not even close! Many people, especially those casual spectators of Top Fuel and Funny Car drag racing, think that nitrous and nitro are the same fuel. Having watched racers explode engines while making a 300 mph run down the quarter mile, they believe that nitrous will also cause their engines to blow up. Nothing could be further from the truth. The nitro methane used in Top Fuel competition is a very volatile liquid fuel and only racing engines designed specifically for it can handle its huge power and destructive force. In these applications, nitro methane is the main fuel source, constituting as much as 90 percent of the total fuel burned. Nitrous oxide, on the other hand, is injected into the engine in comparatively small amounts and delivers smooth burning characteristics that enhance the fuel’s combustion process. Whether it’s a small 55 HP shot of nitrous added to a four cylinder engine or a 300 HP shot added to a properly built V8 racing engine, nitrous allows you to add just the right amount of power without fear of damaging your engine.

Modern Performance Meets Hot Rod Attitude You Don’t Have To Sacrifice Your Muscle Car’s Soul Just To Get The Benefits Of A GM LS Engine

Hated by Neighbors, Envied By Friends

Let’s face it, nothing grabs our attention at car shows and cruise nights better than a car with an aggressive, hard thumping, high-performance idle. In their ongoing quest to provide enthusiasts with the PERfORMAnCE, SOunD & DRIvABILITY they crave, the COMP Cams® engineers expanded the Thumpr™ series of camshafts to

include grinds specifically designed to give late model LS engines real hot rod attitude. Featuring specially engineered profiles for late model GM LS engines, these camshafts provide the perfect combination of early intake valve opening and long exhaust duration with a generous amount of overlap to maximize your engine’s nasty idling characteristics without negatively impacting streetability. Thumpr™ Camshafts and matching valve train parts are EASY-TO-InSTALL, direct replacement components that exceed the quality and durability standards of OE parts. Finally, your late model LS powerplant can provide an authentic hot rod experience. Without question, the Thumpr™ Camshafts are in a class of their own when it comes to serious “seat of the pants” performance and a head-turning, aggressive idle.

f you’ve already made the switch to a modern GM LS engine for your classic hot rod, you know that the benefits of “start and drive” convenience and unmatched reliability are incredible. But these great engines fall short when it comes to experiencing the traditional sound and performance of a REAL HOT ROD. Not anymore. The Thumpr™ Camshaft line-up from COMP Cams® was designed to add authentic hot rod attitude to modern engines without sacrificing reliability or street manners.


LS

Toolkit

Valve Spring Compressor This piece is specifically designed to work with all GM Gen III/ IV LS-type engines. The easy-to-use custom design enables the removal of two valve springs at a time without the hassle of removing the rocker stand or any of the other installed rockers. The tool works with cylinder heads installed on an engine or with the cylinder heads off. Starting at $102.96

Camshaft Degree Kit

Crankshaft Socket This specially designed LS 1/2" drive socket allows rotation of the engine assembly while a knurled retaining nut holds the degree wheel in place. To make things easier, it can be loosened while on the crank snout so that the wheel can be turned independent of the engine when finding TDC. Starting at $50.61

(Cylinder Heads Off Engine)

Engine Plug Kits It’s easy to overlook the smaller parts of the engine until the final stages of the build. That's why COMP Cams developed this Engine Plug Kit. It includes all the plugs needed to finish building or upgrading your LS engine. Made from brass and galvanized steel to resist corrosion, the plugs in this kit will last for years without rusting or becoming stuck in the engine block. Starting at $30.86

Grind

Ordering a special grind camshaft may be the best course of action when building your LS engine

There is no more critical part of an engine than the camshaft – often referred to as the brains of the engine. The patterns and position of the lobes of the camshaft determine the timing and lift applied to the valves and valve train. So it goes without saying that selecting the right camshaft is clearly the most important decision you make after engine choice. When it comes to LS engines, COMP Cams offers a wide range of standard camshaft offerings. For street engine applications, these are more than appropriate. But that does not mean they don’t invite creative camshaft requests for more complex engine applications. Many high tech engine builders are very sensitive when it comes to developing their own cam designs and other valve train gear. They have specific requirements that require special orders. COMP Cams created literally thousands of special grind camshafts for LS engine builders in 2013 alone. That’s a lot of custom ordering. But that does not mean lengthy wait times or extra costs. COMP Cams custom grinds take less than 72 hours to grind and cost no more than a standard part numbered camshaft. The following pages include COMP’s popular shelf-grind camshafts. This will help many engine builders select from a wider range of cams and lessen their development time. But remember, if you still don’t see something you like – your custom cam can easily be created.
