Just for my information, what would be the theoretical horse power of a 1999 RS with a 2087 Twin Screw Autorotor (Rimmer Sidewinder) Supercharger at 9 psi? I know, I know, I know. There are a lot of other factors involved, so if you care (and have an extra minute) see mods below:

Unorthodox crank pulley
Upgraded fuel pump
BEGI rising rate fuel press. regulator
Twin core laminova intercooler (front mount)
Heat exchanger
Eaton bypass valve
3" Exhaust

Thanks guys!

i would venture about 250-280. just enough to cause your clutch grief yet not enough to pop the trans without some abuse.

Seriously, though, the 250-270 range sounds about right.
