ring gap for n0s

Post  bbf-falcon on April 4th 2016, 8:41 am

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.

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.
