I am not interested in gas mileage, but rather in maximizing engine power and not boiling over. I have a 1981 Pontiac T-1000 (Chevette) with 1.6liter 4-cylinder engine and air conditioning. When I normally drive, I have the driver's side window open about 1-2 inches and the econo-vent on. I like to drive fairly fast (60-70mph) but often do not get power for hills, etc. Would I get more power with the window closed and the AC on? Would the engine be more likely to boil over during a 1-hour drive? (I wouldn't mind being able to do 75-80 with the AC going, but suspect I would need a better car for that....)
