I'm doing alot of research on bolt on power for my 03 FX4 4.6 to try and get the most power that I can with out forced induction. Here are some parts that I have been looking at purchasing.

Troyer Micro Max Tuner
Troyer underdrive pullies
Magnaflow SISO exhaust
E-Fans
CAI
JBA shorties

The little 4.6 came stock with 231 HP and 305 lbtq.

What do you guys think the setup above will make???

I'm guessing around 360hp and 370-380lbtq to the wheels

On Troyers site the advertise 40-45 hp with the tuner, no less than 15 hp with the e-fans, and around 13 hp with their underdrive pulleys when used with the micromax tuner and 10hp with the MagnaFlow SISO catback. This is what I'm basing my gussetimate on.

 

Not be an *******, but No Way. What they say under all the hp gains is bull.

You will never gain that much from those mods.

 

You MIGHT be around 300 at the flywheel...

 

That is what I was thinking, thanks for the responce guys now I will just have to save my money for the positive displacement blower.

 

I would guess with you mods...
290 350 flywheel
218 262 at the wheels....

 

Go with the blower, you won't be disappointed.

 

I'll go with either the Kenne Bell or Whipple, I know from driving my 03 Cobra the positive displacement blower will get the job done.

 

Right now it looks like it will have to be a Kenne Bell, Whipple doesn't offer a kit for the 03 F150 with a 4.6. I know that the positive displacement blowers will make more power and torque the the centi-type.

 

I would say MAYBE 275 at the flywheel with those... Stock hp is usually over rated, and all those mods wont gain you that much, only the tune, and efans will gain you. dont waist your money on shorty headers, as they gain a hp or 2.

 

Thanks for all of the replys guys. I'm going to go the KB route.

 

don’t forget the TP tunes, they’ll complete the package

 

Glad to hear that! KB ROCKS!!! even though i dont have one....

 

I'm not sure that's true.

Per MZ89's post. If you added up all of the advertised hp gains you are supposed to see from bolt ons, you'd have 800 hp!

 

That is pretty true... Id stick with roots/twin screw.

 

It will have to be a KB and nothing else!!!!
