I am interested in swapping out the 6 rib system for an 8 rib system on my Whipple/FRPP HO SC. So far I have all the pulleys except the SC pulley. Can anyone tell me if the Cobra SVT pulleys will bolt on or do I need a pulley specific to the kit Whipple/FRPP kit? I am looking to keep the 3.25 just move to the 8 rib. I know Thump RRR has the 3.1, but I don't want to up the boost.

liberty, i can't say for sure, but it seems
like one of our crew (onederful100?) might
be running a cobra pulley.

hopefully someone will chime in soon and get
you an answer.

yes i have a cobra pulley from a friend.
i changed to the 8 rib kit from BGG performance.
i originally ordered the Reichard racing 3.2 from them but the bolts didnt match up
so a friend gave me a 3.5 pulley from his terminator and it fits like a glove with the 8 ribs.

thats what I would suggest. Contact Dave @ http://www.bggperformance.com/

after re-reading the OP better, i don't have the SVT pulley, i have a pulley from a terminator with a whipple.
so it's a 8 rib whipple pulley actually.

Thanks for the responses. I did go with the 8 rib kit from Dave sans the tensioner and idlers, which were already purchased from Thump RRR. Dave only had the 8 rib blower pulley from Thump RRR in 3.1. Given I am already at between 11.4 - 12.4 lbs. boost (belt slippage), on stock internals with a 3.25 pulley, I wanted to drop the boost. I ordered a 3.4 from Reichard Racing. Well see if it fits. If not, it looks like the terminator pulley from a Cobra will do the trick! Thanks. I really couldn't get a straight answer from Whipple. I guess it "depends."
