I was there at Madon Dixon when his Cuda turned 9.45. There was a pretty big smile on his face afterwards.

The most powerful is Tilley's in Aussie land. There was a dyno graph on .org of his slant six where it made over 600hp.

The only other one might layton drake. Never heard actual numbers but it ran 9.80's in 1/4 and was not that light.
