I actually did as many searches as I could think of and couldn't find what I was looking for.

The purchase of an MCS would be my first super charged car. I have had a number of turbo charged cars. Because of the demand placed on the needle bearings in a turbo charger, I had been advised to bring the engine up to normal operating temperature prior to fully getting on the boost.

Does the same concept hold true with a super charger? Or, because the mechanicals or so different than a turbo, the concept does not apply?

As far as I know, you don't need to do any special "warming" of the bearings as you do with turbo cars. As a matter of fact you're under boost almost all of the time (except when the by-pass valve is open). Remember the SC is belt driven off of the drive shaft, so it's spinning all the time the engine is running. IIRC, superchargers spin at lower RPMs than do turbos (Whine vs. whistle) so the bearings aren't taking that much punishment like they do in turbos.

Just let the engine and fluid warm up to operating temperature just as you'd do for a normally aspirated car.

 

no, because the supercharger doesn't go through such a drastic thermal expansion and contraction like the turbo it isn't as sensitive to being boosted while cold. Still, it's good practice to let the water temperature at least reach operating temperature before getting on it.
