The result esult of the project was a big block Chevypowered VW Corrado that became one of the most successful cars in UK drag racing during its time on the track, winning many events in Super Gas, Super Comp, Super Pro ET, and specialist VW classes, plus, it would win either a track or national championship almost every year it competed. Eventually, with a 555 ci Jeff ull Chevy motor it ran a best of 8.60, and after having achieved all his aims with the car, Tramm sold it to a German racer. “Both Spencer and I held a long standing ambition to run in Pro Modified,” says Isaacs “...but neither of us could afford to do so on our own. However, after a marathon tea-drinking and bull-talking session at the CIRC workshop, we hatched a plan to join forces and campaign a car between us. Originally, we looked at a nitrous car, as I had some experience in running nitrous, but with the FIA European rules mandated unleaded racing fuel, the ability to gain tuning tips from experienced people in the US was essentially nullified. This was compounded by a leap forward in UK Pro Mod performances during the planning stages,
meaning that a competitive nitrous Pro Mod motor was getting very exotic and very expensive.” Neither had much experience with blowers, but Isaacs had worked with turbo EFI technology on a championship-winning Street Eliminator car that CIRC built for Steve Nash a few years previously. “I was very impressed by the accuracy of mapping and tuning that was available when we were involved with Steve’s car,” added Isaacs. “Plus, the UK track and weather conditions can be quite variable, and the turbo EFI route offered a lot of tuning ability for different conditions—we could also make more than enough power with off-theshelf BAE engine parts, so the decision was made to go turbo.”
DIFFERENT IS…
Th re are a number of items incorporated into the build of this Duster-bodied Pro Mod that you might not see anywhere else, and that is mostly because Isaacs built it through his own shop, so why not use it as a platform to showcase his work. “We chose the 1970 Plymouth Duster body because it is different,” tells Isaacs. “Basically, there were
