OK I search and read some topic on this already, but some say gap the top ring smaller than the bottom ring, some say gap top and bottom ring the same, and others say gap top ring bigger and bottom smaller. SO..here's my build up that I have

cp psitons 75.5mm
Eagle rods
Arp studs
stock sleeves
I'm shooting for 300 whp with a good tune, so..if any of you guys have some experience with ring gaping or has done a similar buid up or know some formula to go by please help me out.

 

when i builded mines with the JE rings
i gapped them to what the card on the rings said

JE at least sent a paper with the ring gaps on them... top and bottom rings gaps are different, so be careful

 

The problem is that CP doesn't come with recommended gap setttings. From what I've read CP leaves ring gap up to the engine builder.

 

Anyone help, our summit ring filer is in today and I wanted to start getting the rings gaped.

Thanks

I believe Earl was asking did you get an electric power'd ring file or one of the hand power'd one you crank to file down.

 

He got the hand crank one, is one better than the other something?

 

hand cranks are fine

i have wiseco 75.5mm low comp. (turbo) pistons. i have read that the gaps should be .017-.018 for the top ring and .020 for the second ring, but i see the same numbers for the larger bore b-series pistons. the sheet that came with the wiseco's says .004 per inch of bore which is what they are at right now w/o any filing done by me. my question is: are the smaller 75.5mm bore (D-series) pistons really supposed to be gapped at the same size as the larger 80+mm bore (B-series) pistons?
