Interesting idea to reduce turbo lag.

It is interesting, but I don't understand how the "bursts" of air into the manifold will change anything. It will still take the exhaust (along with the "bursts" of air) to get the turbo up to speed when you step on the accelerator. The turbo's power all comes from the same place - the exhaust air of the engine. It just seems to add a bit more load on the electrical system to have the electric pump pressurizing the source for the "bursts" of additional air.

I believe the compressed air will be released into the manifold before the turbine inlet, beginning the process of bringing the turbo unit up to speed, thus filling in the "gap" in energy that causes lag.
