Default electric fan question

Is there any advantage in running two e fans? If so what? I was told that i could run one to push and the other to pull.

Absolutely you can, just be aware of having the flow restrictions caused by having the fan in front and the potential of not cooling the outside fins properly. I'd recommend a single puller fan rather than two myself UNLESS you have a track only drag truck and need to cool it properly with no airflow.

Ive got a single electric fan and I've NEVER had my temps come up over 50% on the guage, even pushing it hard through the mountains

Pros and cons to both.
As CdnoilRAM pointed out, having a fan in front of the rad restricts some of the air flow, so if your cooling system is at near capacity, could case issues. For maximum cooling efficiency, a single fan that is properly sized for your rad will be about the best way to go.
However, 'WHEN' your electric fan quits, the second fan (if you have it) will at least provide you with some cooling, likely enough to get you to where you need to go to get it repaired.
So....pros and cons to both setups. If I were to do this mod, I would do the single fan setup that CdnoilRAM has done......but I would carry a spare fan motor under the back seat. (I don't do tow trucks!)
