I work for Roush Racing and my cuz works for Eaton. I gave him a call about 3-4 months ago asking about a supercharger kit for my Durango (he also drives a Durango). He said that they don't have "aftermarket kits". You would have to buy a supercharger and make it fit your vehicle (a lot of customizing work). The bad thing about this type of s/c'er is that you will probably have to change your intake manifold (may void your warranty), and they are a lot harder to install & dial in (tweak). I've been doing some research for some time know for a s/c for my Durango & have decided to go with a centrifugal type (i.e. Powerdyne, Vortech, Paxton, etc...) vs roots type (Eaton, Maguson (which is basically Eaton for aftermarket applications), Kenne Bell, etc...)
In my opinion, my 5.9L w/ 3.92 LSD, puts out a lot of stock torque (good for take offs). I want the s/c for more power after launch. Which is when a centrifugal kicks in (as your RPM's get higher). A roots type will give you boost all the time (except for by-pass). My buddy drives a new Lightning and it has a Eaton s/c. It works good, but he has a hard time not breaking the tires loose, ALL THE TIME! At about $200-$250 a tire, it can get pretty expensive. A roots type also takes more power to turn (i.e. a stock F-150 puts out 260 HP, the Eaton s/c'er takes approx. 65 HP to turn, but provides about 105 HP net. Making the Lighnings 360 HP) A centrifugal uses a lot less, usually no more than 10 HP.
Just my $0.02
