I had the flexlite fans, but they melted down and spiked my radiator pressure/temp and BAM!!!

no more factory radiator. I had them wired with ignition switched power, The thermostat that it came wiht sucked!!! I took the thermostat off in a week.
They seemed to flow slightly more air at static , but the stock fan kept the car cooler at the road course. I think Jeff Hood had the same findings on the road course also.
My anwser is that the flexlites are good for cars who drag race/ street race, but stick wiht the stock fan if you take your car to the road course.
