How many different sized pulleys can you typically use for the same blower belt? For example, if you have a 4" blower pulley and want to drop down to a 3.7 or 3.5" pulley, does it always require a shorter belt, or is there a range that one belt will work for? I use the SDCE setup but I have not changed the blower pulley so I wasn't sure since there is a little bit of adjustability with the tensioner.

Edit... Right now I have the 8rib 7.25" sdce crank pully with a 3.7" blower pulley and it uses a (gates) belt that is 53-1/8" long.
The belt they sent me with the 3.4" pulley is 51-1/2" long.

Yes you need a shorter belt with a smaller pulley. I oreder a 3.4" pulley from SDCE and they sent me a shorter belt with the pulley.

lol, no problem. i have talked to two people who used the same size belt when they ran the 3.7 and 3.4" pulley. i guess i will have to take a look and see what will fit best.

So you have to run a different water pump with the ASTER bracket ?
Also is the procharger crank pulley a 8" ?
They used to be a sponsor here, their shop got flooded last summer and they had to get that sorted out. I think you have to go to the 8 rib with their set up.
You use the standard ProCharger 7.65 crank pulley with the Aster bracket. Bob

That ls2 water pump is definitely lower profile than the ls1, and the blower belt is very steep going up to the sdce tensioner. I think it would hit the pump with the 7.65 pulley. You probaly could get away with the 7.65" pulley with the sdce if you ran the ls2 pump as well.
Heres a pic of how close the belt is to the ls1 water pump.

After a lot of research I found a perfect diameter 8 rib pulley I had stand offs made for it. I also had the additional idler pulley and standoffs made. Its working well so far I see 20 psi in my near future. Ill post of when I have more results available. Thanks for looking!!


Notice the water pump clearance and the standard 7.65 Crank pulley
