How much boost did Audi use to make 330bhp in there fierce groupe B cars.I also imagine that a very radical cam was used along with some other tricks. Just wondering and dreaming what 300+ bhp would be like in my '84 Ur-q. Cheers, Jim '87 5Ktq (IA Stage II, Forged wheels, Euro Lights, 230bhp?) '84 Ur-q (Tap Box,8" Wheels,H&R Springs,Poly Bushings, Exhaust,235bhp?)
