To Supercoupe, OR an M90 installation on something else

Yes & WRONG.
Yes: The M90 on an Early SC spins @ 2.5 x crank speed. That is why SC's need an intercooler.
Wrong: It is wrong to apply Supercoupe supercharger speeds to NON-Supercoupe applications. Our stock M90's are overdrive 250% from the factory.
If you spin the M90 less than "we" do, it will produce less boost, AND it will produce less Heat! So telling the guy to run a larger SC pulley, just doesn't apply, BECAUSE you are baseing the "larger pulley" idea, on the Supercoupes 250% overdrive, which the guy Isn't using.
