With my last motor rebuild I had the motor on a dyno and it showed 101HP @ 8000RPM. This is not the HP at the wheel, I don't have that info on my car. How would I figure out how much HP I am getting at the wheels? Andrew

Of course, that may vary somewhat depending on one's tune. I don't think anyone is at 100 HP, but I could be wrong :-). Perhaps others might want to share their results with this list :-).

Does anyone have any argument that 100 HP is a good HP to use for comparison on the well sorted and piped Rotaxes currently? These are all crank HP-not HP at the tranny output shaft or at the ground. It ought to be interesting to watch the passes on the straights :-> Chuck >From: "Jay Novak" <[EMAIL PROTECTED]> >Reply-To: [email protected] >To: <[email protected]> >Subject: RE: [F500] MC HP Creep >Date: Thu, 12 Apr 2007 10:15:54 -0400 > >I think you are wrong about the possible HP gains Jim.
