I'm running a 2.6" Pulley on the JRSC, (gives about 10psi), with FC 3 piece UDP's. The UDP's underdrive the JRSC to about 8psi....at least that's what I'm hoping for.couldnt help in askin about your sig...8psi w/udp???? udp's drop your boost pressure due to less rotation. or are you talkin bout your blower pulley b'g smaller?
The problem is, I have either the very first or second JRSC EVER made for the focus, and it's different. Reason being, the 4 lines on top were becoming a clearence issue on some of the different Focus models other than the ZX3, so they changed it.my jrsc only has 2 on top an 2 on the back (on top you can see ^^^^) 2 on back;1 to the pcv 1 to the black box
I'm using bosch platinum's. I'll take some pics tonight when I get off work.What sparkplugs are you using, also did you disconnect the battery to reset the computer? Can you post a picture so we can see how you have everything hooked up?
