Anyone know the changes in eaton blowers over the years, specifically on thunderbirds or other cars where the blower is easily adaptable. (ie not gm where the intake is cast onto the blower)

I've heard of early style and later style and of mp90 which is slightly different maybe integrated bypass valve... I don't know the distinctions...

Also what advantages are gained in coating the rotors?
What is to be gained from porting the case mods?

Thanks in advance...

I found that the early T-bird rotors are uncoated and have an oval inlet port.

94-95 Thunderbird supercoupes have coated rotors and a rectangle inlet port which allows the supercharger cooler temps and higher boost without leakage.

So when looking for an Eaton m90 the 94-95 blower is the one to get.
