I'm building a stroker with a 3.75 Crank throw, 5.7 rods, 9.5 CR, Heads are CNC'd LT1 castings. I know there are alot of variables here but can someone "ballpark" a pulley size for the supercharger to achieve 12 to 14 lbs of boost.

Thanks.

 

Anyone out there with a D1SC?

 

You might toss out a few of those variables for us to work with. : )

 

What else would you need to know, besides cam info, to make an educated guess? I'd let you know the cam info but I don't have that information yet. I'm just looking at what others are doing to see where I could be at.

 

Maximum rpm is very important.

 

12 lbs of boost at 6000 RPM. Cam will be a moderate blower grind around 220/230 with a 114 LSA.

 

A pulley between 3.40" - 3.60" should get the job done.
