After running a 10.98@126mph with custom made crossover pipes, we have decided to go with a Process West Race Plenum Kit!! This kit is a breeze to fit over some of the other kits on the market. We have yet to tune it yet. Prior to the race plenum kit, the car was making 382rwkw with a 50/50 tolulene mix running 16psi, and 340rwkw on pump fuel. The turbo is factory, onlt having the exhaust housing ported and an actuator fitted for boost control. After we get some time to stick it on the dyno to tune it we are hoping to see a race tune figure of around 400rwkw and hoping to run at least 10.5 at Willowbank, and a street tune making 330rwkw. All on a stock BA Mk1 Bottom end!!!! Watch this space!!!
