WOO! first post, took me forever to track down a good forum. so i have a 2003 dakota with the 4.7L my mods are in the signature. incase there not... so far ive added a CAI, TBS, headers and dual exhaust, however its not a true dual. im trying to estimate hp on my truck. it says stock 235, plus the mods maybe 40-45 hp. before i supercharge my truck i would like to have some where around 330-350hp. to be sure it will get over the 400 mark with a super charger. let me know all help will be appreciated.

cheers

 

you're most likely going to need a heads mod. Check out krcperformance.com, they got some good stuff.

 

you're definately going to have to do cams if you want to get anywhere near 300 hp

 

okay so for a build up to getting my 4.7 supercharged. maybe pick up a set of heads. but would i get the fully ported, assembled/ported or the turbo heads? then i would need cams too, anything else? throttle body? intake manifold? with the supercharger do i need the pulley kit? any help would be awesome. thanks guys

 

intake and throttle FOR SURE your going to need all the air you can get wit an SC. also, for a little extra cash, you could sell your TBS,it is doing absolutely nothing on your fuel injected motor.

 

mines got one....(came with the truck installed) i thought it looks like a cool mod...but thtats it...LOOKS

 

Ya, they don't work at all on our motors.

I like thefastman.com for a good TB talk to Dan.

Exhaust that baby. Remember to install a Y pipe that is 3" diameter. A nice MagnaFlow system at least 3" all the way out should help those headers out!

 

without going completely custom, is there a true dual exhaust for our truck? or will my gibson dual work with a new y pipe? and some high flow cats maybe?

 

just get rid of the stock y-pipe, and i dont think there is a true dual "kit" for dakotas. it would have to be custom

 

i went to the fastman website and looked at there throttle bodys, what would you recommend for a size? 68.5mm?
also who produces a good, strong intake manifold?
and last but not least i wanna swap out some plugs and wires, maybe even a little more of the ignition. lemme know any ideas you have. thanks
