do a pulley swap on the supercharger, and underdrive pulley set, longtube headers, off road h-pipe, and a tune should help out alot and should run your bank account into the ground

^^^ Underdrive pulley set?? ... on a 03/04 Cobra??!!

Yea I've seen them on latemodelrestoration.com unless they were for a GT only

I don't think that underdrive pulleys are necessary for the 03/04 Cobras. If anything they'll rob you of power. Do your research on that one. The only thing I did was double bearing idler pulleys w/aux pulley,and a 4lb lower crank pulley. With this combo on a stock eaton will get 450-480 rwhp. A ported eaton you'll get low 500's.

You should be in the low 500's with a ported only Eaton ...520 to 530 range with a 4# lower and 550 range if you add in E85! ....see the link above!
