    Fit the biggest fan you can. Chuck on a CSR electric water pump. If you're dragging it, set the fan and pump on manual switches so you can run just the pump down the track and turn on the fan afterward. You can also leave the pump running after switching off the motor to cool it down quick.

    just a pointer about buying electric fans..check on the CFM'S of them..i've seen big 17" that only have half CFM'S of say a 15" fan of another brand...the CFM'S is what you want to look for..that is how much air the fan pushes or pulls
