Idea to eliminate turbo lag..., ...or am I crazy. Options

[CheesyLobster]

So I just though of this idea that could eliminate turbo lag completely, and I was wondering if it’s ever been tried or anything.

My idea is that the turbo and piping for the turbo would be normal, except just before the throttle body, there could be a split pipe. Attached to this pipe would be sort of a short ram air intake, except there would be a high quality one-way valve in between the filter and throttle body. This way, before the turbo has spooled, the engine would get air from the short ram intake, and be like an N/A car. But once the turbo is going, the pressure in the intake pipes would over power the short ram, and close the one-way valve, thus utilizing the turbo piping setup.

Kind of confusing, hopefully this crappy pic I drew in paint can help. I drew in with a 7afe.

So what do ya guys think? Seems like it could work if the 1 way valve is good enough.

a little electric supercharger would do the trick, use the 1 way valve to protect the weak supercharger from the turbo preasuer, but that way you can get the 4-5 psi off the elect. SC but once the turbo spools up it will make more psi then that and close the valve and your good, just set up the valve to have a switch to shutoff the SC. but there is not extra work on the motor ot spin the sc (because its all elec. and you dont get the lag.

only problem with your idea is that when the motor is at idel, the turbo is still spinning, just not much so that there is still air preauser in the intake pipe, and some is more then none so your valve would always be closed.
