Ive ordered my GM Stage 2 kit and i've heard a lot of people talking about running smaller pulleys with this kit since it runs so rich.

I see cobalt addiction has a 2.79" pulley... is that what everyone else runs? Also will I be alright with just the shortened GM belt or will i need to change my tensioner as well?

Thanks

 

alot of people run Nate's pullies. the stg2 belt will work fine

 

where can you get nates pulleys, and is 2.79" the proper size?

 

i would get 60lb injectors if you want to drop to that small of a pulley

 

well would 2.9" be better to run with the gm tune? or 2.85? whats safe with the gm tune

 

get a nates 2.9

 

I'm running 50lb injectors with a 2.8". I say get it tuned if you want to try it with 42lb injectors

 

ordered a polished nates 2.9"

thanks guys

 

stage 2 already comes with a 2.9...

 

no, it comes with a 3"

 

is it? hmmm, i dont remember

 

Yup--3" bro, 2.9 is completely safe (but please account for altitude/air density, temperature, and humidity to be on the safe side) -- 2.85 is borderline--I have one of those sitting around but I"m not going to try that one just yet.

 

id rather be safe then sorry. thanks

 

Hehe you're very wise. I'm not going 2.85 without bigger injectors, a wideband A/F gauge, and a custom tune, which could be a while. Sticking with 2.9 for now.

 

i will put the 2.9 on and scan to make sure everything is ok
