Heffner Performance has finally finished their R8 Twin-Turbo package, which manages a nice 536 HP at the rear wheels (check out the dyno sheet below.) This is while running on only 6 psi of boost. Heffner promises they are working on an R8 V10 version of the twin-turbo package as well, which should be coming soon.

Take a look at the pictures and video below, and contact Heffner Performance for more information.

Heffner Twin-Turbo R8

Heffner Performance is known in the high-end tuning world for creating ultra-powerful versions of cars like the Dodge Viper, various Lamborghinis, and the Ford GT. Now they got their hands on an Audi R8 and added their own twin turbo system.

The stock R8, according to their dyno tests, produced 353 rwhp. After Heffner added the TT system with only 6 psi of boost, the car output was increased to 536 rwhp – a gain of over 50%.

Not content with this of course, Heffner is working on a 100 octane system that will likely reach 600 rwhp, and a twin turbo system for the R8 V10 as well. I’m looking forward to hearing more about this in the near future.
