HP Increases for 4.7L Flex Fuel

[strokeZ]

Has anyone done significant mods to their 4.7L and what are your HP gains? I have done all the standard "bolt on" mods except throttle body. I have been looking to install a blower on it (preferably a twin screw) and get about 400 HP out of the thing, but would settle for the mid 300's. I am not sure this is even possible. I would like to stick to a supercharger given all of the issues with turbos in aftermarket mods. I know many will ask "WHY?" - Let's just say "JUST BECAUSE" Yes, I should have purchased a Hemi and all that jazz so lesson learned. Any input would be appreciated. I have talked to Kanne Bell and they don't offer anything for the 4.7L

Forget the blower. If you want some serious passing power what you need is what I have disquised as a storage pod. It's a J.A.T.O. rocket. Gaurenteed to give you a kick in the pants when you just gotta pass that other guy.

Straight from a C-130 to the rooftop of your commander! If you want to go cheap you can go to a hobby store and buy some Estes Rocket kits and tape the engines on the back. Be sure to post some pics if you do though.

So I have talked to Lysholm, Kenne Bell and Vortech. No one seems to be interested enough in the 4.7L to do aftermarket mods such as this. Seems like they are steering away mainly from re-flashing the ECU especially when 4WD systems are involved.

Well dude this is half the fun bro. Making stuff work and fit that is not made for it will make it a one off mod. If you want one get one thats close and invent the rest to make it fit. I think finding one to fit will be easy. The hard part dealing with the computer that will be the challenge.
