constant fan speed pulling air through the condensor

 

Not a good idea. Even on the highway you'll notice a difference.

 

Isn't the stocker a clutch fan? If so, they don't actually draw much for power until you feel/hear it kick in.

Taking it out would no one yield a near unmeasurable mileage in fuel mileage, but very much increase the chance of overheating. $10 in extra fuel it may cost for the next few months of running the stock fan compared to no fan, vs. a rebuilt motor for the one you overheat . . .

You may free up 2-3hp I would guess, if that's worth it, you need to re-range your priorities and finances.

 

On hot days you can, maybe you have noticed the AC get warmer when you sit at a light.
