D1 pulley size Have a D1 procharger ready to go on with SDCE kit and was wondering what size pulley I would need to run a safe amount of boost on a stock short block?
I purchased a 4" pulley to go but fear it still may be too small. I have an F13 cam with about 6 degrees of overlap so I expect to bleed some boost but still want to limit it to a comfortable amount.
Thanks

How high you gonna spin your engine?
For stock short block, I'd stay with the 4", but thats me because i'm a little conservative. My stuff is forged and i run the 3.4" and 7.25" crank pulley and see 17psi @ 7000rpms...
EPP should chime in here shortly...

I have a FMIC with the 3"" core I think. I thought 4" would be too small and thought I would need to go to 4.25 or 4.5. I don't think that would fit with the SDCE bracket and tenshioner.
Thanks guys
Thanks guys
Gotta remember that the SDCE has a smaller crank pulley than the ATI. its 7.25 i think. At any rate, I make 8-9 at 6500 with a 4" pulley. I have a MTI X1 (230 on a 112 i think, dunno the overlap)
i have a 4.5 and SDCE and it all fits just fine.
4.5 on a stock block to stay safe.

You should be okay with the 4.00" pulley with the smaller crank pulley that you have with the SDCE kit, considering the camshaft you have. I don't like to see more than 8 lbs of boost on the stock shortblock, but there are a lot of variables that affect how much boost your car is going to make, and I think you'll be there with the 4.00" pulley.

The ATI ProCharger 6 rib crank pulley is smaller than both the SDCE and the ProCharger 8 rib crank pulley. I believe the SDCE is 7.25 in diameter. The ProCharger 8 rib crank pulley is 7.65 in diameter. Bob
