Thread: Ring gap for boost?

Looks like the 4b11 guys are having issues with ring gaps being too small running 2bar boost lol. .004"-.008". Ya, too small. The rings supposedly butt ends and cause pistons to crack. Or perhaps people are detonating and cracking pistons. Just food for thought.

The 4b11 guys also run a .017" gap on most boosted engines that are built. But for 2nd gap and modified street boost they see .023"-.024". I wouldn't worry about .020". Its perfect, throw em in!

One the mains, this side out on #1 and #5 correct?

Looks good! and the numbers will all face the same direction.

sweet thanks man! that was a quick reply! lol
