Thats definitely some high rpm, so it equates to faster wheel travel for the hp number obtained. I made around 66.7 hp on my motor at 8650 rpm with pro circuits, and a low-mid port job. Of course now that I ran it, I bought a dyna cdi, dyna coil, and bumped up the compression and changed out the reeds again. So, I ought to be around 69-70hp when its tuned in.
