Somender Singh's new combustion design. Great results on high compression cars!!

A guy on the Pontiac board has experienced better TQ, HP, smoother idle, better fuel economy and cleaner oil. He has been doing this to all his heads and this could be the next big thing in cylinder heads.

Maybe VPE can pull this off for my ported stk heads.

Anyone have anything to add to this?
Any takers on trying it?

It's being used on closed-chamber heads only. Open chamber like 3.8 heads really don't have anything to cut into. Raising the compression ratio is masking the gains. I would like to see a cut with no change to comp ratio and view the results. Increasing compression ratio, for all practical purposes, increases efficiency (more power).

Good point John , how are you supposed to judge the gains from the groove when your also raising the compression ratio from 8.5:1 to 10:1.

I too would like to see a constant compression ratio test, but if they are able to raise the compression ratio that much after the mods, and couldn't before because of knock, while keeping the fuel octane and timing constant (or maybe retarding the timing because with the extreme turbulence you don't need as much which also lowers the octane requirement), then that's a pretty good test. I have to read all the data on the website to see what they've done, however.
