Art, your fans should be off during a run. They can not move as much air as ram air at speed. They actually block air flow at higher speeds. If you use a FAST XFI ECU like I do to control your fans it automatically turns the fans off @ WOT. GM ( probably Ford & MOPAR too) shut the fans off about 45 MPH, and just let them "windmill" so as to not restrict air flow through the radiator. That would hurt cooling going down the track, or driving on the highway. If you control your fan with the ECU, you might check with the mfgr, it may shut them off @ WOT also. If not, maybe a button the throttle hits @ WOT to shut it off?
