Does anyone know how to calculate the btu's created by a 4 cylinder motor??
I always wondered why you could not air cool a small water cooled engine.
I figure that water cooling became necessary with V8 motors because there was no way to get much air between the cylinders.
The old VW opposed 4 was air cooled, but the newer Subaru which is very similar is water cooled.
I wonder if you could blow enough volume of air through a water cooled motor to cool it? I know from heating and cooling for buildings that CFM= 1.08 X DeltaT , but I do not know how many BTU's a Motor produces. I guess I could figure out how many btu's by the number of gallons per hour the motor would consume.
I have a Subaru motor that I want to put in a dune buggy, but I would rather not have a radiator sticking out of it...
