Default 11.0 to 1 compression on 10lbs.

has any body tried this
i was wondering what you guys thought about running 10 lbs on 11.0to 1 compression with a forged bottom end and meth

is it possible and would it be reliable or would it be a time bomb

Assuming the bottom end is screwed together well, and the tune is 100% spot on, you should be OK.

I think you would be Ok. Cablebandit is running 10.3:1 with meth and he loves it.
Im bumping my CR up to 10:1, maybe even a tad more.

if you guys think it is ok i will probably leave my heads on there for now and go see what she does on 10 lbs


im hoping i can at least cross the 550rwhp for now

I'm running 9psi from my magnacharger MP122 on a 10.9:1 compression forged stroker. No issues, I'm even going to bump up the boost a little. The pulley is on order.

758 rwhp about that cause it keeps changing with dyno and air temps but about there.

gets around 26 mpg interstate highway in a heavy GTO
AT max boost im flowing 300 lbs of meth its a dual 15gph and 10gph at 100psi nozzle meth kit. think i could lower the meth but im not willing to chance it. sucking in alot of hot air with my air intake. close to headers.

10k mile running like this so far, going strong

Sorry guys would answer more but just left bar and chick ready now
