The temperature of the intake charge does not impact power in a turbocharged system; only the turbocharger duty cycle. The only case where this is not correct is when you've maxed out your turbocharger. [edit] Ok, never mind, you're talking about NA engines. FWIW, I don't think its possible to create a high pressure zone without experiencing prohibitive cancellation issues from heat. Additionally, the volume of air a vehicle will ingest at its peak power producing RPM won't create a need for a low pressure zone; the air flowing in won't have a much different density than the air moving through the intake due to engine demand.
