Heffner Performance is working on putting a twin turbo into the Audi R8. Have a look and especially listen! Awesome.
The car is by Heffner, and while we find the video a little lacking (you’ll see), we must give it up for the soundtrack. Audibly, this is about as good as things get. And what do you get if you let Heffner replumb your R8’s engine? How does 536 wheel horsepower on 93 octane sound? Sound like about 640 crank horsepower to us.
