I've got a comptech SC with a 3.5" pulley and I've heard that some people are pushing more boost than I am.

I'm getting 8lbs of boost with the 3.5" pulley and aftercooler installed.

Anyone know where I can go to see how much boost a pulley should give me...by size of the pulley? Or does 8lbs sound about right with my setup. My complete setup is in my sig. When I try to do a search, people talk about their pulley in boost or by its size, they never mention both in the same topic.

Thanks,
Dave
