pulley for a jrsc?
im triing to figure out if i have the big boost kit on my jrsc or not. i have 6lbs off a dead stand still and it will max at 11lbs. anyone have ideas to tell which pulleys i have? i want more power and cams are already on the way.

im not positive but im pretty sure thats the BBK based on your boost #s. Just search the size of the pullys and measure yours

Sounds like the BBK but measuring your pullys will confirm , Cams are not going to do much for you with the jrsc

What header do you have ? Air intake ? Exh size , plugs , thurmostat ?

Do you have a SVT or ZETEC? The BBK pulley is around 2.5 inches for the ZETEC. I do have a brand new BBK kit for sale for the JRSC if your interested.
