M112 was used as the production supercharger in the Lightning and Harley Davidson F-150s. It's got a very small inlet, unlike the M122 and was top feed. It was never used on the GT500.
So the start of the thread wasn’t to determine which blower would work better where. It’s a question about the relation of PSI and Volume. So the statement was a bigger blower and smaller blower with make the hp at the same psi. If you were able to remove parasitic loss as a factor and keep Charge temp the same would they make similar power?

So I guess that’s the actual question. What is the relation to boost pressure and volume? Can a bigger blower move a large volume of air at a given pressure when compared to a smaller blower? So is a 4.0L blower moving more air at 15psi than a 2.0L blower at 15psi?If you remove parasitic losses and heat, you disregard the differences between the blowers - which just makes it an academic exercise. So with those assumptions, the answer would be yes, but it's not a real world scenario.

What is the relation to boost pressure and volume?
OK, so if you use one air pump to inflate a tire to 35 psi, and then use another air pump to inflate the same tire to 35 psi, do you think the volume of compressed air is different based upon the pump you used? The volume of air is the same at a given rpm and boost. Heat does impact the density(not volume). Colder air is better as it contains more O2 than hot air, at the same volume, in addition to helping avoid knock. My 0.02.
This is an interesting discussion. So how would a blower be chosen as the "sweet spot " in size for a specific CID application? At some point the blower would be too small and at some point a blower could be too large. I would guess that spinning the blower slower would generate less heat, heat is something we all fight, heat robs power.
And on the 2007-2012 Eatons, I had always understood that they were the same size M122, but with a color change only in 2011?
