I never had a chance to dyno the car with the smaller (10psi) pulley, but with 6psi and no cooling I put down 330 on a mustang dyno My best run at 5600ft DA was 12.61@110..

I messed up my 10psi pulley on the move to Greenville so I haven't had a chance to get another yet but I'm working on that. I put in a meth kit to do the cooling and going to aim for the 11's which shouldn't be hard if the clutch holds together.. weeeeeeee
