Check my maths...
This skid steer has a 23"x13" engine cooler core 4.25" thick the other half of the radiator is hydraulic oil cooler of similar size at 23"x9"x4.25"
The engine is 73 horse power.
It has a 18" ish fan spinning a max of 2900 RPM. I don't have any specs of the fan blade but I have a picture.
The fan motor is 14.53 cc per rev with a max pressure of 2600 psi
The pump to drive it is for the sake of easy maths 10 GPM (21cc per rev)
Using online calculators for hydraulic horsepower I am getting 15 horse power, converted to watts is 10,000+ watts....
Are we really that under powered in electric fan cooling with 850w fans?
