The guys over at Supercar Specialists uploaded a video to YouTube of a Heffner Twin Turbo Lamborghini Gallardo Spyder on the dyno.
The car is capable of over 850 wheel horsepower on race gas. It isover 20k miles since this car was twin turbocharged, they did some regular maintnance and a few dyno runs to be sure everything is ok. In the end it seems to be running great, flames are still coming from the exhaust.
