ARIAS Piston to Wall Clearance?

Re: ARIAS Piston to Wall Clearance?
If I recall correctly, Honda recommends (on a D-series, not sure if its the same for anything else) 0.0004 - 0.0016 P2W Clearance. Like I said previously, mine are at 0.003 but I told my engine builder I was shooting for around 300-350whp.
As in "solid as a rock", I meant they have absolutely no movement in them. I can't say for sure that yours are too loose, but in my opinion, it doesn't look right.
Good luck!

That theory seems valid until you get to the high hp guys at like 7-800hp, they don't run 0.007 p2w, right?

with any forged piston .0030 is minimum i would run for lower hp. most the full race turbo cars i see run .0050 .0060 and up but I'm talking 800 and up hp

Thanks.
Haha. Nope, no jumps yet. Just snow drifting
Good to know. It seems .0045 is plenty for 500whp

Re: ARIAS Piston to Wall Clearance?
are you guys ordering new rings when you make the ptw clearances bigger? Or what are the gaps you are running on the rings?

If I understand you right, no. You gap the rings according to the power you want to run. The rings that come with the pistons are fine. Arias says run 22 minimum for the top ring. Since Im running about 30psi (550whp) Im gaping my top ring at 26 and my second at 22 since this one sees less heat. (Arias recommends 20-28)
