9:1 with my thicker MLS
Hyd Roller .576 in .594 ex Lift 239in 245ex Duration @ .05 110LSA

Motor made 135 at 9.5:1 And it's always seemed to me like it's made about 20% less hp than comparable setups. It only made 520 crank with 5lbs, granted it was with a 14:1 afr, but still it should have made close to 500 without boost.

Once I sealed up the intake gaskets and tightened the belt after dyno day, it made 10lbs.

Not going to do any testing, time to pull the heads, and then the pistons. Pistons are coming out for sure, I can only hope that the cylinders are ok. I'd like to do this without pulling the motor. If the pistons are ok, I will resuse them. If not. I will get some blower slugs and drop my CR and order a smaller pulley when funds allow. It would be awesome to run 19lbs...

BTW, broken rings or not, I slaughtered the guy that I was racing. And I'd do it again, 60 psi in several cylinders or not. Watch out suckas!
