This may be old news to some of you but this company says they have a Paxton kit worked out for the Hemi Rams. At minimal boost it gets about 350 rwhp. They're fabricating the brackets on a Magnum right now and will have kits for Magnums and 300Cs within weeks. I assume that will transfer over to the Charger when it's available. They got it to work with the current ECU and does not or is not affected by the MDS system. They have another more aggresive kit that delivers 500 rwhp. I think the price is under $5K. Sounds like all us Hemi owners can go even faster if we want to.

I also found a twin screw supercharger from Kenne Bell.

If you goto the link that you gave it says that they will not be offering a supercharger for the 03. They are trying to develop one for the 04's
