I just buyed a Paxton Novi 1000RR kit, at last the car is getting a blower yeah!

But it came to my thoughts that as today I have Steedas UD pulley set installed. What impact would that have on the supercharger? Will it spin to slow? The kit is supplied with the 7-8 psi pulley.

The original pulleys for the car has been thrown away by the last owner.

Any idea about this? If this is the case, are there any charts you can use to determine the psi boost if I buy another blower pulley to compensate?

You cannot run the underdrives and the blower and have it setup correctly.

Offer here in 4.6L to ship someone your underdrives if they will ship you their stockers. Thats what i had to do.

Or you could go to a Pull-a-Part or junkyard and try to get them off one of those motors. The blower won't make very much power and might not even hit boost with those pulleys on there. Find a friend who is N/A and tell him that you will trade him straight up.

Junkyard for Mustang parts is probably not an option considering he is in Sweden LOL, someone here will trade you I am sure.

The kit will probably only make around psi anyways...with udp's on there you would hardly make any boost.

Thanx for all the replies!

I will se what I am going to do about it. I found a guide on the net considering this, and they swapped the supercharger pulley out for another one to compensate for the crank pulley.

But then again it is hard to know which pulley for which psi.

And yes, there are alot of junkyards in Sweden but none of them have any Mustangs. To bad!
