    450R dyno

    Web surfing and found this post on another forum (excellent power on stocker):



    This is our stock bore 450R.
    It has:
    Viciuos Cycle Hammerhedz 13.75:1 Pitson
    Vicious Cycle Port Work
    Vicious Cycle PulseCharger Pipe
    Honda HRC Cam

    Stock rod and valves.
    Easy drop in parts for a easy on the wallet build.
    Using Honda cam (extremely easy on your valve trail), that many already have (Hot Cam Stge 2 is VERY close).

    YES. 53hp is good but it had some help. If Brian(wpp) put a 44 lectron carb on and ran meth, I'm sure he would it 55hp or better

    The bottom of that pic with the run details is partially cut off. Some of the runs are on meth, some are on gas. The meth did not show any measurable peak difference, but it helped the low end tq and over rev. It's pretty easy to tell the gas runs from the meth on the graph......noticable down low.

    I just saw this, and its my engine.
    The runs that show earlier and later power and torque are methanol. The other runs are gas.
    We do not use Methanol on this engine, just wanted to see what it did.
    There was not even 1 hp on methanol on the peak number.
    Brian woudl not get 55 with Methanol, but he would have power earlier and later.

    Thought I would show a picture of what that engine sits in.
    Many changes since that engine, will update later.
