I just want to see what you guys think I should run on my D1sc 8 rib setup with the 7.65" crank pulley. I have a set of 1-3/4" headers with an ORY, LS1 manifold, and everything else is completely stock on the engine (stock heads and cam). right now I have a 4.38" 8rib pulley I bought for my kit but I'm a little concerned that this might give me too much boost. I was thinking I might buy a 4.50" pulley but I don't know what type of boost it would give me. Also where I live the elevation is 1000'. I spoke with Bob and he told me with my setup the 4.38" would be near 8-9psi and the 4.50" would be near 7-8psi. Let me know your suggestions guys and also If you could let me know your pulley combos and what boost you're running with them it could help me decide what to run myself.

Thanks again guys,
Jason

Stay with the 4.38"

4 inch pulley 12 pounds of boost at max throttle also if youre doing a boosted car you shoulda gone with the 1-7/8 headers for better exhaust flow

Stay with the pulley combo you have. I think you'll be fine right there. 9psi is ok.

I've got a 4.00" pulley with the 7.65" crank and I'm seeing between 10-11psi at 6400.

the 4 inch pulley is the way to go

Thanks for the info guys. I think I'll stay with the 4.38" pulley for now. 4.00" is way too much pulley for me right now. If it boosts too much I'll just change my shift points.


Thanks,
Jason
