Highest boost output from JRSC?

Whats the highest boost output kit Jackson Racing has available for their charger? I heard it was 12psi, others say 15psi.

:confused:

Might want to contact Jackson Racing directly. There are a lot of pulleys for the kit, but the more boost, the more load it puts on the engine and you lose initial power to spin the impeller. I bet it will push enough to destroy your engine. Any turbo or S/C can do that. Just a given.
