I'm not faniliar with "boost" where woud a leak happen?
I was thinking SC. I tried to move the impeller by hand. I could only move it slightly. Should I be able to move it at all?

a leak can happen anywhere there is a slicone to metal joint. From the charger to the throttle body on internal IC skis, or from the SC to the IC and then from the IC to the TB.

Thanks, I thought "boost" had something to do with the more complicated upgrades. I guess if I had a simple pressure guage tapped in the line near the TB I would be able to keep an eye on the boost and know when something wasn't right.
Everything's tight. It must be the SC cluch slipping a little. At 50 hrs I guess I need to decide if I should have the 100 hr rebuild done early, buy a better SC or just try to tighten the cluch a little. I live in Virgina and ski season is short. Thanks for the help. Ed.
