Who sells a nose pulley for the JRSC kit? I see some pople list 3" Pulley in their sig lines. Where'd you get it, what does a 3" pulley do for boost? Im trying to do some research for our boost upgrade kit...

i get mine from my diablo tuner. he does a lot of work on 03 Cobras and Lightnings so he has a ton of extra pullies laying around!

Focus Central

If it's smaller than the stock one, it makes the supercharger turn faster.

go to a machine shop they can make you one...even smaller if you want

But if you go smaller, you'll need to change the belt. It might be easier to just take the FocusCentral kit.

asp or...check out cfm, the 3.0" is off the m45 blower for the reg zetec, u can find them used for cheap and run at about 7psi
