I'm in the process of finally finishing the new motor on my car and was looking for some input on the ideal supercharger setup. First I'll say the car is a street car first and foremost, and will be a nice weather daily driver, that I can take to the strip when I'm in the mood. The new motor is a 4.3 stroker, 8.8:1, forged pistons and rods with ported big valve heads and custom DD cam, plus bolt-ons. I also plan on running water/meth injection. From what I remember, the stroker motors aren't very rev happy and tend to make a lot of low end power. The MPX tends to make more high end power. I currently have an MPII to top it off when it goes back together, OD is undecided.
What would you consider the ideal M90 setup for this motor configuration? Right now I have the following options, but I'm willing to change them.
1. Run the MPII as is.
2. Put MP rotors in the MPII for an MPII-S. As an aside, has anyone done this?
3. Pick up a pre-owned MPX case/inlet and run that with bare rotors, and maybe some time down the line put the coated rotors in.
If you think OD is relevant to the discussion, I'm not interested in spinning the blower like crazy, I was thinking 15%OD MPII, 20%OD MPIIS, 20-25% MPX.
Thanks.
