| Re: high velocity vs. huge porting Yes I understand what you are saying but I have used hv on my 660 stock bore raptor @ 69rwhp from a baseline of 33wrhp it has beat several 720 out there to include 720 built by the same builder but with the norm hogged out porting. I'm just curious if somebody has spent the time to due this type of porting on these small engines?? also cyl57 do you ever use epoxy on your porting or just shaping what is there?? |
