That's just there to take up or loosen the belt for different pulley combos with keeping the same belt.

Here you go Doug.

I know you sold car, but I’m in a similar situation. What pulley combo did you use to solve the issue?

Hey I just responded to your PM, but as crazy as this sounds my car ran terrible that day at TX2K because I had two cracked heads. I attributed a dip in boost to an issue with the blower system / belt but the car ended up having two cracked heads and I had to put a new motor in it. The good old days

What are these different pulley sizes going to do? Getting the head unit to spin slower , faster? Does that change where the boost comes in or just for power?

Usually folks change up their pulley on their blower to gain more boost. Going with a smaller pulley requires changing the belt size.
