Nice, that's like 440 on a Dynajet. Now I know why Alex and Brain can't hear a thing - no ear protection! I also see they haven't figured out how to exhaust the dyno room yet. Fumes like that are better than drinking a few beers:)

How hot was it when they did the dyno? I know the room gets really hot during the summer.
