JUst like the title says . How much boost will my d1sc procharger make with a 7" crank pulley and a 3.4 head unit pulley give or take. I know there are a lot of factors. But just a round number for the intjector estimate. The set up is a ls2, 232/240 .595/.608 115 lsa cam and ported 317 heads thanks for any help

He's been having a small problem for a little while now. We were all trying to help and iron it out. When I had my D1 combo I had a 7.25" SDCE crank pulley with a 3.70 blower and was seeing 11psi or so. You should see more then that on your combo...I'd guess around 15psi.

You're going to need top upgrade to the eight rib kit, shown in the above link. It has a 7.65 crank pulley. I would go with the eight rib 3.40 blower pulley. You are going to need the 918853 harmonic balancer and I would go with the crank pinning kit. You should see approx 6-7 psi with the change, it will make a huge difference in power. Bob

Alright cool so I wouldn't really see much of a difference if I upgraded the crank pulley with the 6 rib kit?

[QUOTE=zackyv55146;17231684] You would if you could find one. ProCharger doesn't make one, there have been aftermarket companies that have in the past. I bought one back in 2002 which make a big difference in boost with my D-1SC. It took it from 7 psi to 15 psi, and was made by SSM I believe. You may find one of these used, but no one makes them anymore. Bob
