Souldn't be too hard to answer my question.. But I just want to make the right decision and not f**k up my car haha. How small of a pulley can I run on my balt with GMstg2/Header/Downpipe/Cat-back/Intake? I have the GM stage 2 pulley on right now. Thanks.

 

wouldnt go under what you have with the stage 2 tune... 3" lowest...

 

Really? Why? I thought supporting mods (i.e. bolt-ons) allowed for a possibly smaller pulley?

 

You would need a serious tune and bigger injectors if you go smaller then the 3" pulley.

 

u can run a 2.9 and prolly be ok...multiple ppl are running the same setups...if u go 2.9 dont go any smaller no matter what

 

Good thing I posted this.. I was gonna go 2.85 or so.. Thanks guys..

 

yah search and look...there prolly 100s of ppl running stage 2 with a 2.9 pulley and there fine

 

... 2.9 no problem with your setup... many people run that setup fine. If you drop to 2.8 get 60lb injectors and tune (can also get cooling mods but not necessary)

 

x2
I ran a 2.9 n 42s on a custom tune for a long time. But like said above i wouldnt go below that. You'll max out your injectors.

 

Alright so 2.9 is sounding convincing.. I really don't have the money for 60lb. injectors and a tune right now haha.. Gotta love Christmas


I'm on the GM stg 2 tune though. Still safe to run a 2.9 right?

 

yep totally safe man, just dont go under a 2.9

 

yeah i am running a 2.9 on the stage two tune. Its fine

 

2.85 is THE SMALLEST you want to go. Bottom line.

 

Alright thanks people.

 

Not saying it was smart but i ran on a 2.8 with stg2 for a year. lol

 

PS have a buddy that has been running 2.85 with stage 2 for over a year now, no problems.

 

I'm running a 2.85 that I bought from a friend that ran it for over a year without issues.

It bumped the torque up a bit, and my car runs smoother than it did with the stock stg2, but my gas mileage suffers for it= went from 27 to 23

 

Mine was actually a 2.79 and it ran like a ****** beast.

 

Hmm... Now I'm debating whether or not this is convincing enough for a 2.85

Most likely a 2.9 would be optimal. I will not be stupid and run too small of a pulley knowing that my car can't support it.

 

you'll need a cooling mod for sure

and I'm thinking of getting a 2.9 just to see if there's a difference

 

2.9 is safest without cooling mods and bigger injectors...stay 2.9 man dont do a 2.85

 

Alright. Seems like 2.85 is borderline safe/unsafe for 42.5lb injectors. Looks like it will be a 2.9. Now my question is.. Are there any differences in performance from a 3.0 to 2.9? Noticeable? Anyone?....

 

Not really, maybe a little but not much..you might notice a little more boost psi but thats prolly it

 

Yeah that's what I thought man.. So I don't even know if its worth changing the pulley after all.. At least until I get 60's and a corresponding tune.

 

yeah u can tell a little difference but not much...i mean but for $50 bucks new or cheaper if u can find a used 2.9 its worth it...boost builds up a lil quicker than with the stage 2 pulley
