whats the most hp at 10 psi you have heard of,regardless of turbo with a mild port??

 

I believe Rikki made 354@10psi on stock twins.

 

that was at 11 psi I think

 

that is still whoop ***

 

Yea that sctually sounds right. Still impressive though.

 

and what, like 30 degrees of timing? Do you mean most power at 10psi on pump gas or race gas?

 

Assuming aftermarket ECU to take care of fuel and ignition, I would have thought 310-320 hp (285 at the rear wheels) would be max. 10 for an ic, 5-10 for an intake, 20 for dp, 15 for midpipe and 5 for cat-back. Will porting give you that much more?
