Heffner twin GT35R turbo R8 V10 5.2 dyno video - 730 whp
The ECU's in the V10 R8's have made tuning the twin turbo setups difficult as it was not as simple as just bolting on what was already available for the Gallardo which shares the same motor. Development has progressed steadily and here we have a dyno video from Heffner at just 7 psi from the two Garrett GT35R turbos. The car puts down a respectably 730 wheel horsepower on stock internals up 272 wheel horsepower from the baseline of 458 to all four wheels with a Stasis exhaust. Impressive and just the beginning for the V10 R8's.
