Intake pipe diameter and length definitely do play a role in the torque curve of the engine. Here is an article that shows some testing:

Also, its widely known that warm air reduces pumping losses and increases flame speed in the combustion chamber. Both of these things increase engine efficiency. Not all engines react well to warm air though due to a number of factors, but it mainly boils down to ignition timing. You get too hot and the ecu pulls timing and you loose some of the efficiency you gained from reducing the pumping losses. Each engine handles the warm air differently. |
Exactly.
My intrepid had a wai and it would cruise at 60mph, 2100rpm with a 3.2 v6 at 33-37 mpg.
Keep in mind that during summer months with ac I had to reduce my grille block in order to keep intake temps low enough to avoid octane knock. I also experimented with ethanol blwnding to avoid knock and was quite successful.
