It would be minimal indeed. With the ac off the pully on the ac compressor spins freely.tt061880 said:

Okay, here is the thing. The belt route above can not be use because the two tensioner pulleys will make the belt rub against each other. Trust me I just tried it. The only other thing I came up with is a bigger pulley on the scissor bracket. This is the pulley right after the crank pulley. I tried to put on the 3.0" pulley from the stock tensioner and it clears the motor mount and I think it will work. Now if I can just find one with bearings in it, I will try it out. If I can't my buddy said he is going to make it work. One way or another I hope to have the K24 crank pulley functioning and running 9 PSI. Also I will need to find a belt that is about an inch longer. I know, here we go with the belt issues again.
Easy there killer. If I have to squelch this belt issue then I will. I may not have a "race" ready clutch, but I can still drive around. Let me and my original belt for the JRSC. 3.4 inch S/C pulley and a K24 crank pulley see what is up. I won't be able to run max boost but I can at least give some insight to the belt issues alot of you have been having. Give me a couple of days.

I get what you mean now Jamie, and I got a few suggestions though. Unless JR send out parts that are in different sizes for different kit, the idle pulley and tensioner pulley shouldn't cause the belt to rub against each other. From my point of view, the made the scissor that hold the tensioner pulley longer than the idle pulley just in case we got a belt that was a bit too long.
To fix your problem, it isn't that hard, just find a shorter belt. The shorter belt will bring the tension pulley away from the idle pulley and that will sove your problem.
EDITED: when I said parts that are different sizes for different kit, I meant that the scissor that come with your kit might have been a bit shorter than the scissor that came with my kit

haha, I was just playing around, but you know that. I am very interested to see what other people are running into because it might help explain my problem. I am to a point where I am thinking about running a video camera on the belt when it is on my dyno (I love saying thatwdsonny said:

I do see what you are saying. If I could draw a picture of what I mean I would. I will try to explain it again. If you go from the crank pulley to the water pump, no matter how the tensioner is, the belt will hit itself. I tried to route it any way I could to get it not to and still would hit. Even if I had a shorter belt it would hit. I guess until you actually try it yourself you won't know what I mean. I thought it would work too until I went out and actually took the parts off and tried it. I also tried the stock belt to see if I could figure something out. I couldn't come up with anything yet. I am getting there though.

To me it is much better not to mess with the belt setup and figure out the problem in reverse. Find the problem then find a good solution to fix it. So if a part is in your way, figure out how to remove or replace that part. Don't rework the belt because then you can be putting strain on parts there shouldn't be strain on.

I tried to use it with the 3" SC pulley but it didn't work. So now I am using the 3" SC pulley with the stock crank pulley with more success. I am running a 62.5" belt because I am bypassing the A/C unit.
Reading about this hose has made me wonder if that was part of the problem, I am going to go back and check when I get some free time.
