highest comprssion running with boost
what is the highest compression you guys are running with boosted cars via turbo/supercharger. this can be a race car,street car or whatever. just curious to see if anyone is running higher than 10.1 on race gas or even more.
LT4's have 10.8 compression and you can run a low boost supercharger with em' if im not mistaken on pump gas? shoot me down if im wrong,just shine some light on high compression and boosted motors.

#1, 1986 Montecarlo with a 406sb with a 76mm turbo, blow thru carb(acts like a little heat exchanger) @9psi on 91 octane with 9.5 to 1 compression. Runs 10.43 @129mph on race gas with boost turned up to 15 psi.
#2, 1989 Mustang with a stock 5.0 shortblock. 66mm turbo, intercooler running 9psi on 91 pump gas with 9.5 to 1 compression. Runs 10.56 @131mph on race gas and boost turned up to 15 psi.
#3, 1987 Fiero with a L67(Grand Prix supercharged 3.8 liter) alcohol/water injection(liquid intercooler) 9 to 1 compression, pullied for 11 psi on 91 octane pump gas. Runs 12.53 @109mph with that setup.
#4 1996 Z28 with LT4 swap, Pro charger P600 with intercooler, pullied for 6psi on 91 octane pump gas. Runs 11.90 @117mph spinning tires pretty bad.
But these are all highly tuned for running on pump gas. I'm not sure if any of this helps but just a few examples of what i have gotten away with on pump gas!
