This is my theory on why they didnt care about the coolent affecting the performance. It goes back to the old rule of thumb.

Cooler air = More power
Warmer air = Better fuel economy.

now with our engines making well over 300 horsepower and more than 350 ft lbs of torque @ 15mpg on highway, give or take, Im sure they werent worry about the performance. I think they would have been more concerned for the porpose, whichever it may be with some added benifit of fuel economy.

True

Warmer air = Better fuel economy.

...but I don't know how you came to this "rule of thumb". Cold air is naturally denser; denser air has, per square inch, more power potential in the combustion chamber.

When the air cold air goes into the intake and is read by the IAT, the computer tells the injectors how long their operation (firing) goes for so the air/fuel mixture is prime for that air temperature. When the intake air temperature increases, the engine responds by A) pulling timing (not good for mileage) and B) dumping fuel (to fight detonation, also not good for mileage).

This is all ignoring that you, as a driver, have the desire to get to a certain speed at a certain rate. That cold air allows you to accelerate to that rate faster, with less application of fuel.

What is this? How do you do this? What kind of performance gain is acheived?

I’ve done all that step by step three times even bought my grandma two more birds and adopted a stray cat but the dam things won’t drink together. What’s your secret
