Jason and his crew at Heffner Performance are among an elite group of aftermarket tuners for exotic vehicles. One of the latest vehicles to come out of their shop with “some added power” is an Audi R8 V10.
The Heffner Performance Audi R8 V10 already has a powerful 10-cylinder engine but that is just not enough for some people. How much is enough? How about 725 wheel horsepower? Sure, that is exactly what this Audi R8 V10 received after Jason and his guys went to work with two Garrett GT35R turbos pumping 6psi of boost at the heart of this amazing project. That’s about 225 horsepower to-the-wheels more than stock.
Heffner Performance Release information:
For the past several months we have been working on the development of our bolt on V10 R8 Twin Turbo system. This system employs twin Garrett GT35R turbos pumping out 6 psi of boost which produces an ear to ear grin inducing 725 wheel horsepower which brings it up 225 wheel horsepower from stock.
To date I would have to say that this is the most refined aftermarket twin turbo car that I have ever experienced. Exhaust noise levels can be quieted down to near stock levels with the larger mufflers and can be a bit louder with the smaller mufflers.
We worked with the guys at European Performance Labs to engineer the engine calibration and the job that they did is nothing short of spectacular.
Power delivery is very smooth and linear and the whisper of spooling turbos makes the hair stand up on the back of your neck.
I would like to give a special thanks to Eurotech Motorsports in New Jersey as well as their customer, John for providing us with this car for development. This car will be used for regular track days and we will be sure to get you some good video once it hits the road course.
