You are right Flettner. I had a huge argument with RK several years ago , as he simply refused to provide any evidence whatsoever in a back to back dyno test that the " crinkle cut "
head with identical squish and CC made any difference in power.
And here in the video , once again , we have a stock head that is being replaced by a RK mod version with 1/2 the squish depth and obviously higher compression .
The guy even measured the chamber shape ( not the actual cc as would have been way more scientific ) and I would guess its probably at a minimum up one com point .
If I did a head with 1/2 the squish depth ie 1.8 down to 0.9 , and went from say 13:1 to 14 : 1 com ratio OFF COURSE it will have way better throttle response , feel good for a butt dyno , and would show a good gain
in a real dyno shootout.
This is COMPLETELY FUCKING OBVIOUS , but seems to escape all the Merican Catalogue Buying Warriors.
The crinkle cuts would reduce somewhat , the added flame front turbulence created by the higher MSV , and add heat soak/reflection area to the squish band thus inducing deto .
Those are comments made from a lifetime of experience in trying to increase the first factor , and trying just as hard to reduce the second.
Am I a narcissistic wanker , of course , just ask RK or NoLuc for completely unbiased opinions on that.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
