I am planning on adding a supercharger to my 05 GT. What would be a better option for adding better cooling, an upgraded water pump or upgraded fan? This will be a weekend cruiser with no racing.

 

How do you know you'll need better cooling, especially for just cruising?

 

If the car is just going to be used as a weekend cruiser, then what is the purpose for adding a supercharger to begin with ? As you're not going to see the full potential nor notice any real benefit over your current N/A setup as a daily driver.. If your looking to improve your car's overall performance over stock, you may want to consider starting out with a good CAI and calibration tune and also look into upgrading to 3:73-4:10 gears, cams, LT headers along with your car's suspension.. That being said, if you have no intentions of running your car beyond what it can handle in N/A form, adding a supercharger is just overkill and pretty much useless IMHO
