instead of pinching, do u think swaping other used piston on other liner is more practical.. let say hyper 8 port piston combine with sts liner.. if it direct fit and tight, do u think can try it..

LSUsportsfreak.......BRING IT ON!!!!! I finally got around to dialing in the diffs on my Turmoil and the P5X is breathing fire.

Nobody answred my question from before: what % nitro does the S7 come shimmed to use. I plan on running 20%, but if its shimmed for %30 i wanna know to take it out.

The RBs come shimmed for nitro up to 25%. They only recommend another shim for going over 25%. They do not recommend removing shims for running less than 25%. Actually, we all run of our RBs on 30%, without shimming. I don't usually add any shims unless I start having a detonation problem.

Good so i can run it off 20%
