My air dam is pretty low. It also seals the lower part of the radiator opening so everything that goes through the grill goes through the radiator.
I have zero cooling issues. I can be in stop and go for 15-20 min before the electric fan comes on and runs for less then 3 min. Then another 15-20 before it comes on again. Normal driving it never comes on. I wonder if I could/should reduce air through the radiator. Is there a fan on-fan off knee that one should shoot for?
I do have radial tires but they are wide. 8” rims with 9.5” tires in the front and 10” rims with 11.5” wide tires in the rear. Probably a lot of extra rolling resistance there. That was a conscious concession to my hot rodding past.
Seems like we've had dedicated threads about this. MPGUINO- controlled servos or such, operating some form of radiator shutters.
AEROCIVIC had a sideways guillotine air-valve, return-spring default opening, with cable-operated opening ) if memory serves me )
Current low-drag variants of passenger cars all seem to offer some type of grille-shutter technology.
