WAI: does no power loss = no mpg gain?

[Jay2TheRescue]

Is your Focus an automatic or a manual? (I'm guessing automatic) My dad has an 08 Focus with a 5 speed, and that's a fun car to drive. I may consider getting one myself. I'm eager to see how a Focus will respond to WAI.

When ambient temps get to a certain point WAI becomes much less significant as far as any improvement.

Try the same system when it gets cold later this year and see what the difference is when you would really benefit from WAI.

Power loss is dependant on engine load in my experience. While on the interstate in 80*F ambient, I'm seeing 140-150 IAT and feel no power loss because I'm already up and cruising 60 mph. While in the city, say a traffic jam, if I'm needing low end torque and IAT's reach 160+, I can feel a big difference... the power is just gone. Above 3,000 RPM the car falls even more on its face. It's pathetic.
