Yes, the Si trim is the way to go.

To spin the charger faster you can either source the 9psi pulley, which is around $200 now from places like ConceptZ, and add a pulley or tensioner to prevent slip. Or, swap the supercharger and jackshaft pulley which are $100 each. But you have to have the right combination to avoid running out of tensioner or you will need to buy a larger tensioner idler pulley.

Hey could be worse, back in the day we were machining longer stroke tensioner brackets..lol.. Live and learn.

This is why I am making a kit that just has it all done for you guys. Si trim and all.
