*,a mate of mine is machining the exhaust valve for me as i dont have a lathe,i have asked him to come in 0.050'' from the edge of the valve machine down 0.050 '' approx and the hard part will be following the throat angle to the stem.CGT wrote: ↑Tue Aug 07, 2018 1:18 pmWhat did you machine the ditch with, how deep? And how much power did it make or lose? Dyno test? Butt dyno?
it might be a complete waste of time but another tool on the shelf to test with and actually see what is does.
my main confusion at the moment is how to form the exhaust port to flow correctly,i see you guys are not concerned with intake / exhaust % ratio to exhaust cam duration and from what i read on ''Special Needs" that was not a factor at all,you had more exhaust ratio and more duration that would of left many people scratching there heads.
it cant be a case of making the port bigger and then saying it has 65% of the intake and then pat it on the head and send it out the door,it cant be that simple surely,
anyway always like "TEAM CREASON" input its always welcome and no you wont upset me with your comments as i have thick skin, aka construction worker
