Thanks bro. It's about 1 1/2 hours away. Not bad. I'll really try and be there.

BTW, the link to your 2.8" pulley post has been added to the thread. Lots of good info in there.

OniMirage

im sure someone has had one of these pullies and im sure it was already shown but is there a dyno chart yet?

CTCOBALTSSS

I can't find the chart but I remember it was like 255whp and 223wtq. It's all about that torque. Those are good numbers.

CTCOBALTSSS

All these answers will work for that new 2.79" pulley that's going around now so here is a bump for knowlage.

SS_SC_Cobalt

CT, that 2.79 pulley isnt going to give gains over 2.8, no difference between the 2, plus I woul d be careful, I know I prefer a name brand on something as critical as a pulley..

cavy-to-SS

just bought my new pulley 3 min ago...cant wait

CTCOBALTSSS

Yeah I know it won't give gains over the 2.8
I don't even understand why it's 2.79 and not 2.8
Good call on the name brand thing. This is a critical part!

Congrats bro. It will be a nice addition to your arsenal.

cavy-to-SS

how do you loosen the belt or take it off

CTCOBALTSSS

This might help. I'm still looking for you though.

Another thing we noticed is that the Pulley boyz ring weighs like half of what the stage 2 ring weighs. Its very similar in quality, and seems to work flawlessly. I will be resetting my ECU soon, but even without that it was noticably faster, especially in the 2500-4000 range. I took a few videos of acceloration and will have them up in a few. This is well worth it, and I love the extra power. I reused the blue bolts, and will keep this pulley on unless something goes wrong, in which case I will swap it back to avoid issues. MY bro gives it two thumbs up.

make sure you have

1.) an extra person
2.) a 15 mm wrench
3.) the GM stage 2 torque bits

Oh I got my CAB's installed today too. 60 bucks install. Glad I shopped arround, as Car V2 was going to charge me 180.... I was like WTF. They are pretty awesome too, but until I get to the track I wont be able to test them as much.

cavy-to-SS

ok got it loosed but now the hub seems to sit out farther then the supercharger...theres a little gap between charger and hub...should that be

CTCOBALTSSS

I don't know bro, hopefuly someone will chime in.

P.S. Thread has been updated to include the gm stage 2 belt part number.

OniMirage

bump to gain an answer to said question of fitment

cavy-to-SS

also the car hesitates alittle....im alittle worried about all this....

SS_SC_Cobalt

which hub the stg 2 hub? It should be flush to the supercharger shaft....take a pic and post it.
also did you reset the pcm?

cavy-to-SS

no i didnt reset the pcm how i do that just unplug the negiative battery

SS_SC_Cobalt

yes for 1-3 mins

Matty

The end of the hub should be flush with the end of the snout.

How is it hesitating? At part throttle?

cavy-to-SS

click the camera on my name and let me know if thats what it should look like...much appricated guys

Matty

Hard to tell from the pic but it appears ok. The end of the hub, by the yellow in the pic, should sit flush with the end of the supercharger snout.

cavy-to-SS

xenozx said that was fine....was alittle worried for a second there.....

SS_SC_Cobalt

yep looks fine!

SS_SC_Cobalt

was talking to a friend today , he told me gm has a TSB to tell dealers to make the bolts TIGHT on the installed stg 2 pkgs, anyone else heard that?

cavy-to-SS

they were alittle tight but not that tight...not for mine atleast...i think i put them on tighter then they did cause i couldnt even get the damn things off

leviticus88

How is it hesitating?
