If you inject pre supercharger you:

2. You cool off the hot rotors significantly increasing their efficiency (heat kills efficiency)

3. You soft-seal the rotors to each other allowing them to be more efficient at producing boost. You can typically gain up to 1-2 psi depending on application whereas with an intercooler you typically lose psi due to pressure drop across the intercooler.
Now I remember seeing it back a few pages... Yeah you're cooling the rotors, cooling the charge, and effectively adding octane. No doubt it's effective. I wonder if all the concern about rusted/pitted rotors is just internet BS, like so much other crap we hear on forums every day...
