Curious - 5000 S/C RPM or engine RPM? I'm hoping it's the former but assuming the latter. Meh. It's too bad S/C's aren't more efficient/effective. Still cool though, obviously.

Right. I get that. But what I don't get is why S/C's can't spin at higher rates, allowing a better ratio of engine-to-S/C RPM (different size pulley I suppose), so that they can do a little more down low as well. I guess V8's (the typically S/C'd motor) make plenty of low-end TQ so no-one ever cared as much about S/C's low-RPM performance.
