So about 1,500 RPM is the switch on point eh... yeah, that's pretty easy on the drive line then. Also, if that's true, cruising at highway speeds keeps the s/c on because the RPMs are just above 2,000 or so.
There is really no switch-on RPM (unless it has not already kicked in by 2,900 RPM, then it will engage by default). I think it's more throttle position and/or load based. When my car is warm, I can get the supercharger to engage at about 600-700 RPM (according to tach) while loading up on the brakes.
