That's true, I'd never really thought of that!
Anyone know a semi driver? Ninja Edit: Neat read, only casually mentions radiator size though: https://gcep.stanford.edu/pdfs/ChEHeX...0_11_trans.pdf Edit II: Also, this: https://ffden-2.phys.uaf.edu/645fall2.../solutions.htm |

my thought on it is that any air that enters thru the grill has to exit the engine compartment, and the engine compartment is not aerodinamic, so it's not so much the smoothness of the grill, but the rout the air takes.
I have a half radiator, with all but about 5"x5" hole left open, and when it was 105F out, the temp gauge never budged above half way. |
banana's right, SVOman. You still need to block the "excess" holeness in the front of the car.
Though one advantage of using a smaller radiator may be quicker warm-up times since there'll be a smaller coolant volume. |
While not totally related to the discussion, I found this. Pretty good read.

What if the engine block needs some air flow for cooling, so I may need to do some testing too... All in all, too much talk, not enough action! :) |
Darin, of course it still needs to be blocked, but if I had a half radiator and left the hole on the other side, :p
|
Why don't you just block off 1/2 of the radiator, that way it ccostt's a lot less and you cann unblock it if you need it?
|
According to Road Vehicle Aerodynamics, the drag of the entire cooling system is somewhere between Cd = 0.02 and 0.06, depending on the vehicle.

Ah, good info, got any links? I really need to start working on the link archive! *boo* myself
Gary, having a half-radiator will also reduce weight in the crucial up front portion of the car, look more bling, give more room to work, and lemme run a turbo if I decide to go the LPT route somewhere in the future. |
Nope, no links, just the book itself. I can post more if you're interested (I need to work on my typing speed). What specifically do you need?
