Supercharge Or Turbo?

Nice read on Bill. The only problem I see there is the super chargers mentioned are very old on a huge engine. Those engines produce alot of power without the supercharger.

I had read somewhere (Allways taken with a grain of salt of course) that to power a current hair dryer supercharger required 5hp. While this may be accurate, it is something I think was tested while NOT powering a engine.

I would love to see an engine supercharged but NOT powering the supercharger itself. 1 test with the engine turning the s-charger and one with it not. It would need another engine/motor driving the supercharger and matching the PSI rpm for rpm, psi for psi during the test.
Same with a turbo if possible.
