I'm getting really interested in supercharging my '97 5.0. Ive seen 3 different systems that fit but have only found information on here about the powerdyne version, and the one that explorer express sells. Has anyone installed the ford racing version? I can find that for about $2600.00 online, that undercuts the other two by quite a bit, especially the eaton one. The other thing im wondering is i've got about 145,000 miles on my motor...I expect I would need a rebuild to feel safe with a supercharger. I apologize if there are already links discussing this. The model number for the one I have found is M-6066-E51. I have a late model 97, they list one for a '97 and a different model number for a '98...i figure the '98 version is for me. Also I am in dire need of headers. I have true duals, the back 2 cats are high flow and that leads to my 2 40 series flowmasters. I know this is the next logical step, but i'm wondering if there is such a drastic power change between the torque monster headers and the ford racing ones to constitute roughly twice the price. Any imformation is appreciated, thanks.
