Clutch fan vs derale single 2400cfm fan
. Air in a rad plenum is no different
So sorry, where is the air turning 90*’s in the radiator system
Anywhere other than where the hole in the shroud for the fan is. The air comes in and through the radiator core fins, then it has to turn 90 deg to find the hole in the shroud ( poorly made flat shroud) to exit.
In a moving car? I’m having a problem seeing this.
If the fan hole in the shroud is smaller than the area of the radiator core there will be an increase in pressure in the shroud. But what I'm talking about is if you put a flat surface in close proximity to the back of the radiator a high pressure zone is created and it will slow the airflow.
Why? The amount of draw on the alternator is minimal
It's not the load from the field cir, it's the load that the alternator puts on the engine trying to power all the load of the car.
40 amps worth of electric fans is 480 watts or 0.6 HP. On top of that direct conversion is efficiency losses, ie maybe it takes 1 HP (745 watts) from the engine to produce 480 watts for the fan.
Is there a size difference between the small block and big block radiator? I have a stock 3 core unit in the wife’s ‘67 Cuda
From what I have seen the stock 383 radiator is physically the same size the inlet and outlet is larger in diameter.
I am sure the fins per inch and the construction of the tubes is different, not to mention the water pump, pulleys, etc.
I have a stock HP/AC radiator and a stock standard cooling rad. The tubes are the same except the HP/AC rad the tubes are (just numbers for example) 1/2" long by 3/16" wide vs 1/2" long by 1/8" wide.
All I'm going to say about the subject. If you think I'm full of **** so be it. I know what has worked and what hasen't in my life experience.
