If the fans are pulling MORE current than advertised, assuming there isn't a failure, they should be pulling MORE cfms. As someone said, check that they aren't wired backwards.

High amp draw is a over load condition, fan is pulling to much air, bearings/motor are dragging the motor down(to much load), or low voltage my guess is low voltage. Over amps will over heat a motor and shut it down. A unloaded blade will cause low amps.(no load on motor) a fan spinning backwards will unload a blade.

That makes sense if you haven't upgraded your alternator or wiring. When my Derales kicked on, it would drop the voltage pretty bad. I put in a truck alternator and it seemed to fix that, but the lights still dim when they kick on, so I think I need to upgrade the wiring.

So here is what I’ve found after a few nights of working on this thing. I was finally able to get my stock fans to fit the griffin rad and got that back in the car. I then vacuum filled the coolant system. At idle in my shop I did not go above 185 and then went out from a little cruise and never saw temps above 195 even ripping on it pretty hard going up hill. I believe my fans were just on the way out and not providing the air flow they should have been. Thanks for all the help and suggestions !

Can you get a picture of your stock fan setup? I've been thinking about going turbo with my car but would want to keep the stock puller fan setup.

Re: Puller vs pusher fans. Nearly all, if not all OEM fans are puller. It is far more efficient pulling than pushing air thru a core.
