So it'* a low pressure ...4 psi....boost
Is it intercooled before the SC

I see that added an intercooler after the SC.

Looks like an after SC cooler too... green coolant hose through the belt, plus the SC sits above the valve covers, not in between.

GM performance parts also produced a twin charged malibu (turbo and SC) that cruised the show circuit for a while. It was the most gorgious malibu I have ever seen.

Parallel twins

Sure, one turbo can be more effective. Who cares? It ain't a twin

In theory it is simple to do. My version would be to engineer a turbocharger with gears in it to attach a pulley to it with an over-run clutch. When gunned, the engine will near-instantly spool the turbo up (providing instant boost) and then the exhaust will take over, taking the load off the engine AND providing more boost.

BUT a few problems:
1. Engineering a gearbox for the turbo that can handle the load AND the incredibly high rpms that the turbo will be operating at.
2. Once or IF designed, the components will not be cheap to manufacture
3. If its not around now then the VERY smart engineers at any car company (except ford ) must know exactly why that is because if a 15 year old kid can come up with a concept like this one on his own (how old I was when I thought of it) then it has definately crossed a few other minds as well.

Why not just a CSC with a clutch? Much simpler to design and control.

Oh ok, well a csc is what it would essentially be but turbos are alot smaller than cscs that are used by themselves (the turbines) and spin ALOT faster because it'* the only way to effectively use the exhaust to make boost. I was just saying that it would be hard to mechanically make the turbine move at such high speeds WHILE under extreme heat from the exhaust.

I thought the Turbo cars remove the SC rotors.
I think they hogged out the BBV so at a certian rpm the turbo'* pressure can bypass the rotors?
