Armchair theory - extreme cold air intake. - Toyota Yaris Forums

The idea makes sense, but it would make no difference, and would end up reducing net efficiency. Let me explain to you why I am bursting your bubble.

1) The amount of CFM (cubic feet/minute) an air conditioner can move is insubstantial next to the amount of air an engine pulls in. It'd be like p***ing in the wind.

2) The gross inefficiency of an any and all air conditioners mean that it takes more power to run the air con than it gains by cooling the air. Simply put, you'd see more power simply by turning it off.

If it's cooler air you're looking for, then the traditional meth injection, nitrous, or other compressed gasses will substantially reduce temperatures. Also, intercooling works too, but really is only worth it on a FI type application.
