Depending on your blower pulley and crank pulley size it could be anything. What pullies do you have?

Ill measure them when I get back from work tonight I'm not positive bought a used kit. Also if I only want to run around 8 psi what size pulleys should I be running?

Assuming you're on the stock CI, probably a 4" pulley, depending on your crank pulley size. I'm not sure on P1's though.

I have a 6" crank pulley and a 4.5" blower pulley (6 rib). Ya stock LS1 besides a TR Blower cam, springs, timing chain, pushrods, oil pumps, and such... What kind of boost do you think it will be pushing? I don't want to go over 10psi id like to be 8-10psi. Looks like the impeller is gonna be going about 32k RPMS. Which is about half the max so would I be safe to assume I'm in that range?

Sorry I don't know how much boost you'll end up with but if you aren't able to find your answer through search then your best bet would be to contact Bob @ EPP. Also, below is a link for information on the 6 rib belt sizes.

Back in '02 I had a 110,000 mile internally stock LS1 with headers and exhaust. We installed a six rib (all that was available at the time) D-1SC kit. 6.0 crank pulley and a 4.0 blower pulley gave it 7 psi. The D-1SC typically makes one to 2 more psi of boost with any given blower pulley than the P-1SC does. With your cam I'd say you are going to need a 3.60 pulley with your P-1SC. Bob

Ok, also the FMU that comes with the kit do I need to install that also if I'm putting a walbro 255 fuel pump?

EPP

The kit that I have the above link to does not come with an FMU. An FMU stands for fuel management unit and is not used if you are using larger injectors and getting the computer recalibrated. Bob

Hey Bob, Where could I pick up a pulley of that size on the fly? Do you guys carry them in stock?

EPP

Yes, we have most of them in stock $85.00. Thanks. Bob
