how many psi can i make or should i say what size pulley can i safely go without longtubes and meth? run mostly 90 octane cause thats basically all they sell here...

what's yalls input on the situation?

 

10 lbs no meth no problem. Keep the tune safe you can get away with more boost and no meth.

 

ok so which pulley would that be.. as mentioned earlier no longtubes.
im thinking maybe a tune and pulley only for now.... 3.0? 3.2?

 

What supercharger? What engine do you have.

 

on my gibbs. my bad.
stock 5.3 with the stock supercharger.
mp112 correct?

 

What pulley is currently on it? If stock I am assuming its 5-6psi.

 

you know i havent hooked up my boost gauge....
ive heard 3.4 or 3.6. not really sure to be honest. i guess i could always measure lol

 

The size should be on the pulley.

 

right on. ill get back to u as soon as i get time to check

 

I don't know whats on it, but I think a 3.2 will get you to about 10# with all else stock. Add a cam and headers and that 10# will drop to 7 or so. I would definitely get a custom tune along with that pulley drop.

Its gonna be addicting for you. Anyone wanna take bets on how long it takes for him to post that he is lookin for 11's?? haha

A 3.0 with cam and headers would make that thing feel like a rocket ship compared to what it is today. I wouldn't go that small without headers at the very least though. A supercharger really needs the right exhaust to see its full potential.
