There shouldnt be any belt slip with a 3.0 pulley should there? An Intense 3.0? I have a billetflow right now and im going to go down to a 3.0 for a little extra hp/tq.

 

Yeah you probably will.

 

with the stock belt - Yes a 3.0" pulley will probably slip. Go to crateenginedepot and buy the stage 2 belt under cobalt performance parts.

 

Hmm I forgot crateenginedepot sells that belt. I just wondered cuase I dont get it with my 3.15.

 

2.9 and 3" is iffy some cars they slip some they don't.

 

I just got a bigger Idle pulley from Intense to fix my slippage

 

I have a 3" and it has never slipped.

 

So should I shoot for the belt or the tensioner pulley? Any which way better?

 

I have a 2.9 with stock belt and stock tensioner and no slip

 

never slipped when I had my 3" didn't have a prob til I went to the 2.6 (w/ adj tensioner at that point of course)

 

After I installed my 3" pulley, at about 6000 rpm I could hear the supercharger start to waiver, which I assumed was belt slip.

 

3" Here and no slip.

 

i was wondering the samething ......i jus ordered a zzp pulley

 

So... some people get slip some don't. I would say safe bet is to say you will get slip. If you aren't planning on going lower then a 2.8" pulley you can just get the belt and don't need the tensioner. If you plan on going smaller then 2.8" pulley in the future then I would just get the adj tensioner so you won't have to buy one later on.

 

you can also prevent slip with a 76 mm tensioner if you dont want to buy a belt. 2.9 pulley with tensioner here...no slip.

 

My 3" ZZP pulley never slipped.

 

Intense's tensioner is about 25 bucks cheaper too

 

Cobalt-addiction.com sells the belts pretty cheap to

 

The GM stage II belt will fix that

 

i just used some belt dressing with my 2.9 from intense and never slipped after a week

 

Get the belt because after a while the belt will stretch a bit and is more likely to slip.
