If i had a jackson racing supercharger with the 6psi pulley, what can i expect by changing to the 9psi pulley? HP? Torque? and what would i have to do to run 9psi safely? (98 prelude)

 

I'm kind of curious about that as well.

 

You could probably expect damaged/broken ring lands and a big bill. Actually I only know one other story that this occured but one is usually enough for me. If you did go that route I would suggest motor work to make sure you dont run into problems.
