I just got back from AutoZone searching for a new belt for my NST Supercharger Pulley, and the guy that worked there told me they don't have that belt. Anyone know where I can get the K070890 belt for my NST S/C pulley?

Also, I was looking for the Blazer Extreme Blue Parking Lights and they also don't have that. What's up with that? Anyone care to help me here?

 

Nevermind i just bought the Gatorback Goodyear Poly-V belt part #4070892.

 

when u gonna dyno?

 

es mucho expensiveo! but whenever i have the time to.

 

If you get some slip with that belt, I don't know if you have a boost gauge or not get a GATES BELT. Karl (icenine) as well as myself LOVE those belts, they're awesome.

 

I've heard good things about the gatorback goodyear belt. I don't know if it would get slippage or not. I bought it for almost $40. How much is the Gates Belt?

 

Gates belt would be around the same price. So far i've experienced slippage with every belt except the gates. If you go to Gates.com they have a dealer locator. I picked mine up at a smaller local shop. They didn't have it stocked, but they were able to get it in a day.

 

wouldnt that belt be a tad longer than the 70890

 

well, from the numbers it should be 2 mm longer...but SimplyScion had it on his NST pulley with no problems of slippage.
