ring gap for n0s

I have never built a engine for n0s so I'm needing some info. How much ring end gap on a 4.150 bore, 12.5 comp. Sbf . 200 shot of spray.

I would see what the ring manufacture recommend , but I would start some where in the .030 range.

I would say pretty close to that also, maybe a tad less but, not much.

.0065" per inch of bore.

What type of pistons??? If they are KB pistons gap them .005 over the piston specs

Ive run 250 w more bore and .022, .030 os a good bit but better a lil loose imo

.026 min .030 max

Thx guys.

Just remember with nitrous a little is never enough, you might want to go towards the big side of where you think you want to be so you can stick some 300 pills in it latter on.
