Can someone give me a rundown on the differences between the various models of MP blower cases and plenums?

MP I - 94/95 Style case only. S port on top, inlet enlarged and matched to a MP Inlet Plenum
MP II - Early Style case only. S port on top, inlet chopped off and a new CNC'ed machine one glued on the rear. Similar to a 94/95 inlet but slightly larger and moved closer to the rotors.
MP III - Early Style case only. S port on top, inlet chopped off and a new CNC'ed machine one glued to the rear. Similar to a new generation M90 with a smile shape.
MPx - Brand spanking new case that is cast. Exactly the same as the MP III except with closer tolerances and the sound ports have been closed.
I hope you dont mean glued as in epoxy, but welded on.
As efficiency increases the heat decreases. Alot of testing has been done in the past to confirm that. I think Charles Warner would probably have some info as well.
The M112 would also benifit from porting in much the same way. Perhaps your next step Ken?
On lightnings and Cobras they typically see anywhere near a 40 degree drop in temps (dependent on whose testing) but I would think a majority of that to be from more IC surface area being used do to the opened up outlet. I have however seen information where the outlet isnt opened as much with still a drop in ACT temps.
Perhaps someone who has personal knowledge can tell their experiences with SC's m90's..But as far as I'm concerned in our case the reduction is due to better efficiency.
The inlet and out let are just as important. But inlet is a little more important on a compressor then the outlet. We are compressing arent we packing it into smaller space.
But also
Think of it as a vaccum cleaner. The vaccum cleaner starts to whine more when you clog the intake then the outlet.
Just want to make sure everyone knows, a roots supercharger does NOT compress air like a turbo charger does. It's more like a fan that forces large quantities of air to pressurize in the manifold. Hence why it's called a "blower".

and for the MPX who knows because they are still at Charles shop
