Taking a closer look at the intake manifold reveals two Heffner Turbo emblems. Running on 6psi of boost with an air-fuel-ratio of 11.8:1 on stock engine internals the Heffner Audi R8 generates a frightening 620 hp at the flywheel on 93-octane fuel. While the original Audi R8 transferred just 353.2 hp to the rear wheels with a Stasis exhaust and Revotech ECU tune, the Heffner Performance twin-turbocharger system produces a gain of 183 hp, resulting in 536.48 rear-wheel hp – over a 50% increase over the original R8. A 100-octane program is also in development for the Heffner Audi R8 expected to make over 600 hp and fly through the quarter-mile in the high 10-second range.
Heffner Performance is also currently developing a twin-turbocharger system for the muscular Audi R8 V-10.
