Does anyone know of an idler pulley you can use without grinding? I looked at intense's idler pulley but you have to grind somewhat. Doesn't BilletFlow make a 2.75 inch one that doesn't require grinding?

 

Do you mean tensioner pulley?

 

Yeah, because I don't want to buy a belt tensioner as of yet. I want my 2.8 inch pulley put on as soon as I recieve my stage 1 and not have it slip.

 

I though GM gave you a smaller belt.

 

The belt only comes with stage 2 bummer.

 

Stupid stage 2....lol jk but does anyone know?

 

memphis go give your dealer the part number for the belt.

tell them to look it up in dealer world. Only costs like $44.

..And you can install it yourself, not to hard.

here is the part #:12597993

i always figure...if your going to do it, get the best thats out there. I think the S2 belt is the best solution to solving belt slip over a larger idler pulley, although it's pretty much the same concept

 

Oh yeah forgot to mention, if you want the belt you will have to wait prob. till the end of the month, as there is none in the US right now, they have to make them

 

lol I don't know if I can wait that long....There was one guy that knew someone at the dealership and had the guy call up GM and tell them that he ripped his belt. If they didn't fix it with in a certain amount of time they would put his car in the category of "lemon". It seemed to work for him but I don't want to go through all of that trouble.

 

Order the 76mm Idler Pulley from BilletFlow. I just installed my 2.7 BF Pulley along with this idler and no slip at all it works great.

 

There is not alot of diference between the two belts..

You can probably get away with the old one till the new one becomes available..

 

ZZperformance has an adjustable bracket for the pulley. You can adjust it to run from stock to below 2.5 if you like. I have one in mine running a 2.8.

^^Yeah but I can't afford it (even though it's only $100). $30-40 is what I can afford. I only make $7 an hour....about 99/100 of it goes to insurance and gas. By the end of the week I have about $10 to myself. It sucks lol. I just spent all my mod money too. I saved that up for 3 years. Still have money for a clutch though, about $1600 but that's specifically for the clutch and I'm not about to start spending that money since my clutch is not that great anymore.

 

The $$$ you spend on that one idler pulley, by the time it will take you to save up to get the adjustable pulley, you'll want to slap on a different sized underpulley and will have to spend another $30-40 to get another undersized pulley.

 

So you're saying wait and save up for the zzp belt tensioner?

 

I would, its adjustable from factory size (incase you need to take it in for warranty work) all the way to 2.5 and below (anything smaller than 2.5 and you over-spin the blower).
