Jed, I have seen a few graphs etc posted but not any details of the implementation, the thing is though I dont actually want the supercharger doing anything at high rpm as it will push heat up so massively, im quite happy for it to just give me a helping hand at the bottom and then just do nothing useful at the top end, including it actually sapping a small amount of power to turn it.
Once the turbo is spooled, it does everything that I want from the engine anyway, its just what happens before its spooled that I want the charger for.
