The first on-board video of racing in South Africa is awesome! Never seen that footage before, and you really get to see and hear it in action against the other's.

Easy - lots of boost, a 4" pipe and dump it straight out the passenger door

Pat D IMSA footage is so squirmy around the world yet every time i watch it I cringe at the fact that Audi doesnt have a Ferrari or a lambo or a astin martin division using the DAMN I5....They made 700BHP and it was reliable sure they were rebuilding after each race BUT they sure as hell didnt have to it was a GREAT motor. I want to see racing divisions for consumers use that motor. Im actually surprised companies like Koenigsegg and other independent manufactures of sports car make a smaller chassis and utilize a single turbo I5...it would be mad! most of them love the v12 Mercedes power-plant and slap 2 small turbos on there, that or a chevy LS based motor (MY favorite) and 2 decent turbos (*think Hennessy venom GT)

Its funny I have dabbed into the 4in downpipes and it gets low, they get a delicious resonance from there exhaust It has to do with the rev band but yes...BOOOST the answer to all our qualms on this FORUM!
