I think that dynoed motor was fresh from the crate, and also different dyno´s different results. But it´s close enough that 150 hp mark.

Here is a ported, machined cylinderheads and Bender quads dyno results for 800 V4. Just over 180 hp on 9300rpm.

NICE TORQUE CURVE, VERY EASY TO CLUTCH. 3:16 (yammie tony)

I was going to say for a 2 stroke, that is one of the flatest torque curves I've seen.
Over 100 ft.lb is a lot of torque from a 2 stroke, that thing must be a beast on the lakes.

And with those rpm´s it must sound great!

Quadzillarecer´s compound turbo´d Vmax-4 is pushing over 560.2 h.p. and 332.0 ft. lbs of torque @ 36 psi of boost.
