How many max PSI can you pump into a stock 13B motor before the apex seals get blown apart?.

Additionally, how many PSI will a stronger motor hold with 3mm seals and dowls and stuff? (max)

Umm 30-40psi on race fuel easily. 3mm doesn't matter, dowel pinning is usually only done when you are in the 600+ hp range.

Well also, it only takes a few psi to blow the apex seals apart, running lean or bad timing/tuning.

It also depends on the engine too.I hear T2 engines aren't up to taking boost as well as the REW and RE ones.

Damn.. who the hell would want to run 30-40 psi anyways.. https://www.nopistons.com/forums/pub...IR#>/dunno.gif

someone that would wanna break their ear drums with the high pitch noise

Oh.. sounds like fun. :smirk:

i'd agree with you on that one....... hehe :bigok:

It would sound quite nice until it went crunch whack crunch grrch agrcha grrrrcha grechaaa

On S4 engine, the rear iron housing will crack at extreme levels. Problem fixed with s5 rear iron housing.

exactly, who wouldn't wanna run that kinda boost. my goal this summer is to run boost like tire pressure; 32 PSI baby!!! :bigok:

S5 engines are very similar to 13B-REW.... REW is still better but way more rare and more expensive

oh yeah i didn't get that new 29psi boost gauge for nothing https://www.nopistons.com/forums/pub...IR#>/boink.gif

lol, good luck. :bigthumg:

put it to good use.. https://www.nopistons.com/forums/pub...#>/biggrin.png
