Shumby, stop whining and making excuses and put that smaller pulley on!

He can't though. CFM is king when it comes to making power. You can't keep adding boost because CFM goes up to dangerous levels. The killer isn't PSI, its CFM...
You can't put on a 8psi pulley and make 4 psi and then fix it by putting in a 16psi pulley and make 8psi. The motor will blow from the CFM. I think you can get away with a 10psi pulley on the motor, but that would put it too close to the limit for my liking.

Not to mention the fact that I think 10psi pulley is out of the efficiency range of his SC housing? I may be totally wrong, but I thought thats why there were different stages for the GTM sc.
