What are you guys using for ring end gap on arias pistons? I used .005" x bore size (3.206") for the top rings and all of them were in spec. Moved onto the second rings and measured them. The gap was less than .010" which seems kinda tight, about .003" per inch of bore. Even JE rings call for .005" per inch of bore on the top rings and .0055" per inch of bore for the bottom rings, so it looks like i'm gonna need to file these rings down a bit. These clearances are based on a motor that will be daily driven and weekend races pushing ~350-400whp.
Tony1, i know you use Arias pistons exclusively on the race car so hopefully you can shine some light on this.

Use the specs given with the rings. If i remember right, it's bore x .006 for the top ring and bore x .0045 for the second ring. It's normal to have to file them.

 

damn tony, good memory!! I think you are dead on unless i forgot after just doing it 4 hours ago on our h22. ours we didnt have to file though but thats for a full race motor.
