Apparently car companies and turbo makers do to as some are considering adding electric motors to turbos to reduce spool time, so I think an antilag pressure system has some merrit.

I think the pressure tank charge should be introduced to the intake manifold though. This has several advantages over introducing it to the exhaust side of the turbo. For one the pressure tank would be smaller to get the same effect. This is because you have fewer energy transfers(from gas to trubine to compressor to intake charge). The other advantage is a gas expanding cools, thus cooling the intake charge. Since boost helps build boost a short 1/2 second pulse would be sufficient to give the turbo a kick in the pants.

You would need a computer system or a brain to know when to push the button to open the pressure tank valve. If you press it right off the line the compressor won't be able to contain the pressure because it isn't spooled up enough. You would have to wait until some boost built then hit it. You could also use a sensor on the waste gate(or your brain) to open the valve to recharge the pressure tank at peak boost.
