Ant, I am with you on this on those numbers. I just couldn't remember the % on per 1,k ft But from the guys in here that has put the si on & also being in fl at almost sea level. No way on a per say stock motor is will push this as a true #.

OP here you do know that the guy running that dyno can make about a 20% chg diff one way are the other in the car's true ##...

A dyno # is just that the truth about the car is what it will run in the 1/4 r 1/8 mile.. Robert

Thank you do much for all the great info. I guess this is going to be my winter mod setup for next summer. I might change my mind last minute and not do meth and might do e85 setup lol I just don't know if i wana go thru the hassle and redo the whole fuel system.

E85 over meth if you have local stations hands down.

E85 isn't the issue. Change the fuel system and money is lol. I think I'm going the e85 route **** it lol

You are 100% correct, the tuner can't keep the top ring land from breaking at 700 hp. I have had two fail and both were very safe on timing. Meth won't stop this. The top ring gap is too tight for that much heat.

and also my other thought is resale. Most ppl wouldn't buy a car with meth injection. They dont even know what that is lol. But if I do a e85 flex fuel system..many ppl are familiar with that n many cars are factory flex fuel cars too.

and many will say why don't u bring it all back to stock n sell it like that..but that's a hassle for me. It just takes the right buyer n if done right with all the paperwork in place.. their will be a select amount of ppl that don't mind a SC corvette n avoid the headache of modifying n buy a fast car outright.

What gap do you guys run on your rings? I run .022" top and .024"/.025" second ring on mine.
