thats awesome timbo Ive got your stroker on the way with some kibblewhites and springs, so perhaps somewhere down the road a ported head may be in order! :head:

i wanna see a dyno run of a 450 kit, on that same dyno, for comparison. im running a 13.8:1 compression 450 piston, with bike airhorn,HMF exhuast shortened 6 inches, and farrar ported my head a bit to get rid of some restriction.

Here you go 450 kit reangled injectors and pipe.Same dyno but much better weather conditions.Oh and the 60hp Honda we are after is actually 56hp.Some better mapping and I know Timbo will get at least 2hp more.So we should be able to beat the guy with a AMA legal motor:D

stock dyno runs same dyno better weather.

is there a 450kit dyno with the same mods as the Stroker, like porting and bike air funnel

Sorry I never got a chance to dyno stock crank,ported 450.I can tell you the ported 450 had a huge hit on top alot like a 2 stroke.Even with tamer maps like moto.If you are out for power porting is mandatory.Hard to believe Cannondale missed the boat in that area.I guess sometimes all the high tech equipment cant beat a knowledgable and skilled crew like Timbo's.:clap:

Oh and when Timbo talks porting he is talking everything from airfilter all the way to exhaust.Obviously a huge amount of work.

..Tim have you tried a smaller intake valve? WWE told me I could cut the intake valve 1mm,with out haveing to do anything else. Stock is 38mm I went down to 37mm. He said even with a 98mm piston the valve was to close to the cyclinder and air couldnt pass very well there. I did it on my 460cc motor it ran well for the 2 weeks it ran.

Also I have dugs cams,or so im sure i do?..I spec'd them out and there no different then my stock ones?? Iv been meaning to talk to Dug about this but hes perty busy right now.

Would be nice to see some torque numbers too. Hp is only half the equation. I bet the stroker gives a nice bump in the torque.

Torque is huge with strokers.No need for a dyno to know that.
