Heffner Twin-Turbo Audi R8 V10 Unleashed – rpmGo.com

There aren’t many people out there who would say that the R8’s V10 Gallardo-based engine isn’t powerful enough. With its 525 ponies, it is more than we could ever dream for a car. The engineers over at Heffner Performance thought that there was still room for improvement so they’ve installed two big Garrett turbochargers in the rear-end of the car, increasing the output to an incredible 725 hp.

Impressive? We sure think so.
