I don't think this was mentioned here, so...

I noticed that Roush has upgraded their 2011+ supercharger kit with a smaller pulley. It is now rated at 575 HP (up from 540+). There is also an upgrade kit for existing owners.

I also noticed that the standard warranty is now for Roush parts only. If you want powertrain coverage, that is separate, and extra.

This is at the top of my wishlist. To anyone running this kit... How do you like it? How many miles have you put on since installing it? Is you car a daily driver? Is the rest of your powertrain stock, or have you upgraded the internals, clutch or driveshaft?

Thanks!

 

Roush is limited by the amount of performance their cars can have since they are sold at Ford dealerships and can't step on the Shelby's toes. No big surprise they suddenly have more HP now that the Shelby does.
