As a teaser of their upcoming twin-turbo Audi R8, Heffner Performance has put the car on a dyno and put it on video along with the dyno results compared to the stock R8 results.

Now, it’s not quite a video, look closely and you’ll notice the wheels aren’t moving, so they probably just took an image and then recorded the sound. It’s worth watching because of that sound though, it sounds magnificent. I’m quite looking forward to this project. Just wish someone could pull off a twin-turbo R8 V10, but if Audi had problems with that, then I suspect everyone else will too.
