A turbocharger does not have the capability of doing anything at idle. It requires increased engine load, which increases exhaust flow to spool it up, hence the reason for turbo lag. You would not be able to rely on a turbo for what you want to accomplish. Like I said earlier, a mechanically driven supercharger would be the answer, but they have efficiency problems, which would most likely negate your entire efforts.
