I've got a 402, D1SC, cammed, ported and so on with the 7.6/3.4 pulley combo. It runs about 11lbs of boost, but I've been plagued with the stock 8 rib slipping, not slipping, who the hell knows if it's slipping, etc. My concern is that SDCE only makes a 7.25 crank pulley... Essentially, my calculations bring me to the conclusion that the 7.25 will spin it about 4000rpm less... The big variable of HOW MUCH slip I'm getting with the ATI 8 rib is what has me wondering if I'll actually lose boost or possibly gain. I'm looking for experiences or boost numbers people have seen with SDCE's 7.25/3.4 pulley set up on a larger cube motor with a D1SC. Any info would be appreciated! Thanks.

a larger crank pulley will help with belt slippage http://www.reichardracing.com/ these guys make one it's 8 inches, they also make the smaller pulley with cuts in it that help but if it does slip it will eat up the belt, the guy who makes them is not available at this time so they dont have the 8 inch and i cant find anyone else that makes one

Reichard still in buss. They made some BA stuff for me in the past. I have not dealt with them as of late and herd some rumors.
