Can I ask what the point of supercharger is? Are you trying to increase the psi of the air entering the turbo with the supercharger first? Why not just increase the boost and use the turbo by itself to get the same horsepower. Or is this to configuration just trying to reduce turbo lag?

Thanks

Supercharge is belt driven; therefore, no lag. Must be supper fun to drive that STI. Instant power like V8 huh or better?

read the article in the June Issue of SCC about the blower/turbo set up, it'll make you think

I was just about to post thesame thing SCC had an article and a Mini-Cooper featured in their mag about supercharging/turbocharging. Very interesting concept, but complicated to set up.

WAIT, I'm confused. I thought that you couldn't supercharge a turbo charged engine!? How would this work? Is the supercharger forcing air through the turbo? Would the turbo work right like this? Like would it be able to create the same or more boost than normal?

They did this to an MR2 in the Ultimate Street Car Challenge (Sport Compact Car) to increase low end responsiveness. Contrary to popular belief there is lag with a supercharger just not as much. Superchargers are driven by engine speeds therefore are directly linked to RPM. Lower RPMs =lower boost. The only difference is that power climbs are linear rather than exponential like a turbo. I don't think its worth it as it increases parasitic drag because the supercharger belt uses engine's power whereas a turbo is running off exhausts gases that otherwise would be going straight through the exhaust anyway. Just my opinion.

The best explanation is in the editorial section of SCC

people build stuff like that to get their shop into a magazine or SEMA or whatever.


But props, way to make it work, I'm sure nobody else will be doing anything like that any time soon.
