CFM question
 

Does anyone happen to know about what CFM the fresh-air (up front) blower puts out on high-speed, compared to the heater blower mounted in the engine compartment? I was going to try a little experiment with a oil cooler mounted inside a spare fresh-air blower, then ducted to the heat exchangers. I was hoping it [f/a blower] had sufficient cfm to cool the oil, pre-heat the heater air and still have descent flow out of the vents. Also, does anyone happen to know approximately how hot the exhaust actually gets, I'm considering insulating the heat exchangers before I install them to reduce the heat under the car in the summer, and help out the heat situation this winter.
