    M62 or M90 for LE5

    Theoretical question:

    If you were going to supercharge an LE5 with some head work to reduce CR and increase flow, were going to fab your own intake, brackets, and everything, and already owned both an M62 and an M90, which would you use and why?

    m90 is larger and if you did porting mods to go along with the cr ratio drop to a range around 9:1 then i would install it.
    the only reason i would put the m62 on is if the internals haven't been changed.

    personal preference really. you need to wright the benefits of each supercharger in a list and compare. then compare the dissadvantages. figure out what your limitign factors are and stick by them to the "T" to limit unexpected problems.
