LMAO that was awsome we come back to the house and your like you guys did 2 burn outs! I could ------- hear you!!!

weldboy105

you are running 11.1 compression heads that is prolly why you are knocking so much.... especially when the boost hits.... why dont you try lowering the cr... or raising the octane level.... just a thought

do you realize who your talking too? ABAZ knows all... respect the man who made this place...

We wanted more power.Yes we know what were doing.I have like 5 engines sitting in my garage so if i blow one ill just swap in another.Just now getting the tunning part down so we will keep you posted on how well the high compression turbo setup runs.Dont worry dude i got the good fuel we will use for tunning.

Well you really must use the same fuel when tuning as when driving normally. Anything else is a potential liquid disaster.

Cadracer

wonder what you are thinking here? Disaster? You scared gonna blow it up?Hey i got to se what they can take before granading.
Think a bone stocker smogged 350 took 425 shot nawz before it let loose wonder if a mild built can take 15psi an 11-1 comp.Gonna fix the down pipe an put the wide band in it an see where the mixture is.Thanks for your concern but i got it handled.

Cadracer

This is whats inspires me on my turbo charged v8 setup.
He ran 16 psi on a bone stock small block an it last a long time.

Just a word to the wise look out for those lil chevy vegas sporting sbc LOL

MegaScott

I haven't seen a blow thru like that in years, most common on that setup is the fuel pressure can't keep up with the boost, most likely the problem here. You need a boost ref. fuel pump (if mechanical) or a boost ref. regulator with a pump that can put out at least 7psi over what your max boost will be. Also any ref line needs to come from the top of the carb to get accurate boost reference.
