Heffner Performance teases Twin Turbo Audi R8

[ErikStenger]

We're starting to see this type of thing more and more. And by "type of thing" we mean dyno teasers, not twin-turbo Audis. Nonetheless, you are staring at the unclothed rump of an Audi R8 with two massive turbochargers sitting on a four-wheel dynometer. And the results are, well, calling them boring to watch would be a polite understatement. However...

The car is by Heffner, and while we find the video a little lacking (you'll see), we must give it up for the soundtrack. Audibly, this is about as good as things get. And what do you get if you let Heffner replumb your R8's engine? How does 536 wheel horsepower on 93 octane sound? Sound like about 640 crank horsepower to us. Watch (or rather, listen to) the video, after the jump.

After several long months of development we have completed our twin turbo Murcielago. As of August 2009 we have tuned the car up to 1 bar of boost which resulted in just over 1100 RWHP. For now we are playing around with the car at various boost levels and documenting the differences in performance with our trusty V Box.

In 90 degree heat the car pulled off a 5.10 second 60-130 at around 950 RWHP. For reference a stock 580 horsepower Murcielago takes around 9.5 seconds to make the leap from 60 to 130.

With a little more boost it will dip into the 4 second range for sure.

The Heffner Twin Turbo Murcielago is an absolute blast to drive and sounds like nothing we have ever heard.
