Suck, Blow or both?

Don't shoot me.....its not a consideration of any sort just generally wondering if it'd ever been done and what effects this would have.
Fitting a supercharger (inlet) to a turbo-charged exhaust setup? I'd imagine boost levels would be ENORMOUS!!

Cheap and nasty "plug and play" supercharger....

..... But not this tosh!

It wouldn't work, these simply cannot provide enough air to the engine, especially at higher powers. I'd even expect a detrimental effect to performance.

twin charging you mean super and turbo oh turbos dont suck for the exhaust there driven buy it to compress the air it would work to decrease lag but you would need to swap over from super to turbo at some point like on the legy tt's

That thing is not a supercharger. It is an electric fan.
They tested them on mythbusters and they actually reduce performance.
They cannot generate any meaningful pressure. It is just a pc fan, they spin at about 2000rpm. Superchargers can spin 50,000 rpm and turbos well over 100,000rpm

The Volkswagen 1.4TSI is a 1400 cc engine that utilizes both turbocharger and supercharger. It produces 170 bhp (127 kW; 172 PS) at 6000 rpm and 240 N·m (177 lb·ft) from 1500 to 4750 rpm."

it swaps over with a bypass valve the sc would slow the turbo when it really starts to spool

I thought all proper superchargers were driven by the crank via a belt, Great for low down acceleration without any lag, How can you switch between the two as the crank is always moving?

Supercharging Subarus in the US is pretty common as they didn't get the turbo models 'til late on

How about TWIN TURBO's AND SUPERCHARGER

Use an electric/magnetic clutch as per A/C compressor - simples

you have a valve that switch's between them so as your reaching the end of the sc the turbo starts putting air into the manifold then takes over
