With the 2.6 or the 2.5 what kind of boost are you guys seeing and also what kind of numbers are you guys putting down. I would guess like 260 to the ground. Let me know, Thanks , Jared

 

Its all going to depend on other mods, you might want to search, i have a 2.7 and i see anywhere between 17-19psi, check vb garage for mods.

 

With the mods listed in my sig., I see between 19.5-20.5 boost (depending on temperature) and dynoed 271 WHP and 260 WTQ.

 

with the 2.6 pulley what kind of speeds are u guys trapping. I would guess like 108-110.

 

Haven't ran at a track since I was stock . I think most people are trapping between 106 and 108 though, but not 100% sure on that.

 

Aren't you hitting too much boost for the headgasket?

 

I belive that the headgasket is good for up to 20 lbs. of boost, I mainly see 19.5. I guess I'm on the border. Not completely sure about the headgaskets boost limit, though.

 

right, cuz i see about 15.5psi with my stage II and 2.8" at 6,000ft elevation.

20psi eh? thats a lot for a 2.8 pulley

 

Their stage 2 kits has a 2.62" pulley.

 

2.5" right around 20 lbs give or take. Yeah its pushing the headgasket but I haven't heard of anyone with any problems yet. Atleast on average that is.

 

Im really hoping to get about 270whp with my setup

 

With racefuel and my setup you can get 270. You should have no problems once you are all hooked up.

 

i just had a blonde moment of mixing topics and not comprehending what was happening.

meh

 

what is the stack pulley size? and what is GM Stage 2 pulley size?

 

Before you change your pulley, think about upgrading your aftercooling system and getting monitoring devices. A common mistake that people don't do and it ends in bad results.

 

anyone?

 

NjHk What kind of monitoring devices are neccessary. I'm Very new to the technical side of cars and kinda flying by the seat of my pants when it comes to mods & Lingo.

 

I'd atleast looking into getting a Wideband.

Also, buy an interceptor gauge as well...great item to have. You can keep an eye on your IATs as well (Intake Air Temperature).

Having these around and keeping an eye on them could give you an heads up if something is going wrong or about to go wrong and you can stop before it does.

 

Thanks for the info NJHK i'll look into getting them

 

Ok, good luck.
