What is the ideal amount of cfm of air for a fan to move to keep my 363 cool. I found a nice one by CFR. Moves 2300cfm at 12 amps and 12 volts. The black Magic Extreme that LMR sells moves 3300cfm @ 18amps. I'd pay $100 less for the CFR setup (fan, shroud, and controller). Is 2300 cfm enough to keep my 363 cool...even in Louisiana summer heat? I have a Summit 4 core radiator in the car that works great. $342 is a hard pill to swallow for the Black Magic fan but I will if the CFR fan isn't enough. What do you guys think?
