I think what BTF is saying is that if the turbo gets air more efficiently (IE, no pressure drop vs a 1psi pressure drop with a longer inlet tube), it doesn't need to work as hard for the same outlet pressure. Less work = less heat, so they somewhat equal each other out.

We won't see a 90 degree diff in temp from cold air inlet to a stubby inlet... at least at speed.

Sounds like a great opportunity for scientific testing.
