How bout this one? Do you remember this one? Twin Turbo Supercharged




I know I've seen that twin turbo / air filters in the hood setup... but not with a supercharger too! o.O
I wonder if it's similar to the first one you posted, in that the setup is SC > TC and not compounding.

Yep, exactly! The best example of this I've seen was a Mini S (older SC'd one)
build by a guy Hubie Fuh, featured in Sport Compact Car a while back. As well as the feature, there was an interesting Dave Coleman editorial / technical article on it. Basically, it was easier and more efficient to compound-charge the Mini by adding a small turbo and routing it with the stock supercharger than try to spin it way out of its efficiency range to up the boost.

I believe there was a similar setup available for the first-gen MR2s that were supercharged, to twin charge.

But, especially with new supercharger and turbocharger technology and the perils of modern engine management tuning, I'd shy away from twin-charging, stock or aftermarket. There should be enough room under the hood to have fun, with the little flat 4 (which should be far back towards the firewall).
