After Heffner developed its gorgeous and convoluted turbo system for the Lamborghini Gallardo, it only made sense to modify it for duty on the Audi R8. Just what kind of power are we talking about here? Plenty.
Preliminary results are at 536HP at the wheels, a 183HP improvement over the stock V8 model.The car's currently in development and pushes a modest 6 PSI of pressure from the twin snails and while running on 92 octane. Expect the nutters at Heffner to bump things up with more pressure and 100 octane fuel, with rumors of 620 HP floating around, that's at the wheel. Yowzer.
Check out this video of the car doing a pull from second through fourth, sounds like a sweet symphony to us:
