OK, actually there is a man with a fan at the front, but that's mainly to stop it overheating. The dyno figures are back along with some quotes...
The bottom line, from the men who built the 422hp, 1600cc turbocharged and nitrous injected Hayabusa:
"That's offensively loud, isn't it?"
"We went for a 140 main, then 150, 160, 170, 180, 200 and then we started to drill out the 200. We run 250 mains on the turbo bikes. This thing is insane."
We have the needle on the last notch, with a bunch of washers under it."
"At full throttle, it's throwing a foot of flame out the back, and the baffles glow orange."
Peak power at the rear wheel is 50bhp, estimated 70bhp at the crank. Max torque is 59.87 ft.lbs at 3420 rpm.
There's a piccy on VOL, and I'll put the graph here, too if I can figure out how...
