And by comparison, a traditional 4-71 will heat the air more than an M112, especially on a 225...it'll also take a pretty good bit of twist away from the engine just to spin it-and that will only go up with engine speed. Even for a dual purpose vehicle, I'm thinking the M112 or one of the TVS series blowers would probably be a better match.
If a modded M90 can push a 3.8 to 300 at the wheels, then I'd venture to say an M112 pirated off a Lightning or Cobra (they sell them all the time), and a fabbed aftercooler would probably rock that 225's world
