Does anyone have any input as to what differences may exist between a Whipple and a Kenne Bell? Sound, quality, ease of maintenance, etc.? Any input would be appreciated. I'm looking at a supercharger upgrade.

 

In your case, I'd stick with the Whipple line of blowers, since the high end Ford Racing line of superchargers are just that, Whipples! It should keep the frustration level pretty low, and make upgrading pretty much plug-n-play. But that's just my opinion. As far as I'm concerned, both companies make top notch products!
