It's hard to argue with the potency of the Audi R8 5.2 FSI. With it's 525-horsepower V10 mounted amidships, the Gallardo-based engine is more than enough motivation for mere mortals. However, some folks out there felt slighted by the fact that Audi detuned the Lamborghini-sourced mill for four-ringed application. Enter the folks at Heffner Performance who decieded to rectify the situation by sticking two massive Garrett turbochargers into the R8's rear-end.
The result? A 725-horsepower twin-turbocharged Teutonic terror that runs from zero to Ludicrous Speed faster than Spaceball One. Oh, and those 725 ponies are measured at the wheels.
