Have any body seen or used this kind of plenum?

I've seen those. A friend built one similar to that. He ended up going blow-through.

Interesting... I'm not understanding what the two duct openings are. Clearly one is the inlet from the blower. why the other?

Wow that's unique, haven't seen that before! I would have to wonder how well the fuel would stay in suspension in that type setup though... I'll bet the centrifugal force inside the blower would be enough to throw it out of suspension and against the sides of the blower. Would probably idle like crap and have very rough lowend, but run ok in the upper RPM. I could be wrong, but there's got to be a reason why you don't see people using them...

Draw through turbo systems used this setup. OEM on Turbo Pontiac 301's. There's a reason that you dont see many turbo 301's anymore.

An idle thought about this type of plenum.

If this supercharger is drawing air/fuel mixture from the carb, compressing the mixture, and pushes the mixture through an inner-cooler on its way back to the intake manifold, do we have a potential bomb under the hood?

Such a pressurized air/gasoline system seems to be a certain hazardous condition.

Definetly. Better hope you don't put into the wall under boost! Ka-boom!
