lets say you have a fan on your car that pulls air through your radiator at 1800 cfm, which is pretty reasonable i believe. 1800 cfm is one thousand eight hundred cubic feet per minute. in any given minute, there are 1,800 "cubes" of air coming through that fan at one foot by one foot by one foot lengths. if you have 2 fans, the total amount brought through the core of the radiator is doubled to 3600 cfm. that translates to roughly 40.91 cubic miles of air per hour. so, given that the fans are running at maximum efficiency, after about 41mph, your fans are no longer helping, but hurting the flow of air.
my guess as to why your head gasket blew was because your friend was beating the shit out of your car, or you need to put some ducting between your intercooler and radiator. the later of the two has proven to be the most effective way to cool your engine down at speed short of pooring ice water into it.
little info my nubian brother type.
when the head gasket was blown the ka was stock. only things that where done where bs mods. z32 ff, advanced timing, a/c removal, ghetto air box mod, and electric fans. Now you have to take into fact that the chuki bumper isnt the best air flowing bumper on the market. so there is some air restriction. hence why heat can and was built up. as for the car being beat on. mmm i can only speculate.
how ever i will give you this. You sir are 1/2 right. reasoning being is simple. say that i used a thermostatic switch as opposed to the high / low switch i currently have. while making a simple trip say a 100 mile trip. "i see that being reasonable" Sure there are a good amount of cfm's coming thru and cooling system. keeping the motor in operating temp. as i either start to come up an incline or up a bridge. more power is needed and more heat in generated. the cfm's are now not efficient to cool the system. so the thermostatic switch looks at the fans and says yo my niggas ya'll be needn to help a brotha out and then in turn they look at the switch and say fo sho, my nigga.
Chances are pretty good that you wouldn't even notice this process happing while driving yet it does. even for a fraction of a minute or two.
but shit im getting like all uber tired. i need to take my black ass to bed before i say something wrong. chances are pretty good that might happen.
