You may want to modify your requirements here. Superchargers
get inefficient above a certain point. I doubt that the SC will able to
cope efficiently with 8000 rpm If you want 105hp, think about lowering
the rev band and increasing boost. On my car I get 98 HP at the wheels
with 6lbs of boost at 5500rpm (after which it tails of rapidly).
A general rule of thumb is that for every 1 lb of boost is equivalent to
11hp,
so by using 7 or 8 lbs of boost, you're going to reach your goal at a
much lower rpm.
