If anyone is interested I've done a LOT of research into superchargers for Subarus. I've got the specs and calculations for a Vortech unit that their engineers speced out for me. I'm in no financial position to develop and sell a S/C kit and my engine isn't healthy enough to be the test mule. Lemme know, I can probably get the stuff scanned and emailed out. I decided on the centrifical Vortech unit because the centrifical units get better effeciency at high rpm and the unit is easier to package in the engine bay (but would still need a drive shaft).
