For the guys that have the GM stage 2 belt with no oversized tensioner, do you have any slipage at all? I know there are 1,000,000,000 threads about 2.8" pulleys, I just want to hear the real life experiences. So, any slipage??

 

with the stage 2 belt, and thats it, people have gone to a 2.7 with 0 slippage.
ive gota 2.85 and its nice and tight.

 

yeah right... good luck trying to pry the belt on.... ask inhale... you should have no slip whatsoever

 

Nice man that is good to hear. I have heard mixed feedback in the past. Thanks

 

Yea come to think about it my st2 belt was a biatch to put on. My other issues is air/fuel now and the choice of pully quality bla bla bla.

 

def don't get the oversized tensioner...

 

the bitch for me was getting the pulley off the hub when i switched over to zzp, come to think of it, my stage 2 pulley is still on the hub, the dealer really puts them on tight.

 

You think my cat would take it? What happens if my filter gets sucked into the intake and gets eaten up by my supercharger? Hmmm so many problems.

 

OK cool. Good to know. Is there anyone at Cobalt Addiction that has a pulley puller?
I'm going to buy the CA 2.79" pulley at the dyno/tune day and slap it on before the tune.
I won't have the right tools to bring though? Think anyone there could help throw it before the tune???

 

Dont worry about tools... we got that covered...

 

Freakin sweet! This will be on before the tune along with the full exhaust! Can't wait.

 

car is gonna be a completly different animal....

 

yer car is gonna be kinda like mine bro, only mines gonna be a lil faster...(yellow=fast;p)

 

Yeah it will. The GMPP manifold will be included in this too. I'll have the manifold, DP and cat back installed before I get to this meet. I just need to slap the pulley on before the tune. I can't freakin wait bro. It's going to be a good time.
Thanks for your help.

 

no slippage here bro, she's tight as uhmm yeah, happy thoughts

 

LOL! Could be! Happy moding bro!

Tight as a nun's ass! Thanks for the input bro, good to hear!

 

Si, Senior

You might wanna gap your plugs down a touch though when you go to the 2.8
Mine are at .038 and she purrs

 

Yeah good call. I'll take care of that too. I think i'll just buy a new set for $12.00
Why not right? Thanks man!

 

if I buy a 2.8 pulley like this one http://www.pulleyboys.com/lsj28.html do I need pulley puller

I have stage 2

thanks

 

If your stg 2 kit is already installed then no.

The puller is only needed to remove the stock pulley, and to press the GM hub back on.

 

ok thanks...and is it a big deference with a 2.8 pulley compare to a 3.0 actully I have 16psi with the 3.0

where is the best place to order a 2.8 pulley. I lived in Canada

thanks

 

Yeah the 2.8" pulley will give you 17.5psi and up the torque about 20ft.lb's
As far as horsepower goes maybe 10 or so.

 

No slipping. And go down to .035".

 

Im not putting one on just incase i clog my cat and have to pay for it all. Im happy with my stage kit. Screw aftermarket.

 

it only takes about 5 min to swap back to the original gm STG II pulley... they'd never know
