Here a couple links to get you started:

The Eaton M62 from a Mercedes C230 Kompressor is probably your best option for a supercharger.

I would check with RedDevil to see what psi m62's are (consistently) good for- 10 may be a bit extreme for daily use. Isn't Skidd at 12,000RPMs to make 5.5 psi?

With whatever you do though, good luck brah

Skidd is just barley making 5 psi with a 2.75" pulley and a 2006 WRX TMIC. That's a 1.909:1 pulley ratio, which comes out to exactly 11931 RPM and redline.

I'm actually going with a 2.6" pulley for a 2.01:1 ratio, which lands at 12620 RPM at the very tip top of the rev range. Hopefully this will result between 5 and 6 psi.

So for 10 psi, you'll have to spin the SC at 14K + RPMs.

^ some/most models of M62 are capable of 14k. And 15 for short bursts.
In fact, I believe the M62 is typically rated to maintain 14k. Unlike the M90 that is usually only designed to spin to 12k. Don't know exactly what 14k rpm on the M62 SC would make for boost though. reddevil might have an idea, even though he ran on a 2.2L.
