you guys that are running electric fans.... Did you upgrade to the cobra r water pump or did u just reuse the stock pump?? Did u notice any difference with the cobra R water pump performance wise??

 

With the cobra r set up it is at least more difficult to go back to stock if you should need to. I realy did not feel much hp chang in the seat of the pants dyno buy wow is it more quiet and the gas milage does seem to be better.

 

I used the Cobra R style water pump, and noticed no difference, performance wise... It's a nice piece though, lighter, etc. If all you are worried about is horsepower, I wouldn't bother.
