This^ and add a different Y pipe (the 97-03 one is a major plug) and a straight through muffler. You won't make it a stump puller or dragster, but for <$600-700 you can make it a different animal.

 

[QUOTE=Austin97;1072007]The intakes are different as well as many other things, but they don't matter as much as the intake.

Mustang 2V 4.6 - F 150 4.6 1997- 2003 same engine, same HP, same torque ratings which would mean no increase in any useful specs. That's what I mean when I say the same engine. A few minor differences, that's it. No difference in performance unless you go up to a 4 V DOHC 4.6 InTech from a Navigator, Continental, Cobra, etc.
The guy wanted a cheap fix for more power, I still suggest a performace chip as the most bang for the buck.

 

I'll sell you my mustang intake and you can swap yours out and see if you still think they're the same. Mustang peak HP/torque is around 4800 while the f150s is around 2800. That's the difference. I agree on the tuner though if you are only going to do one thing.

 

Thanks but no thanks. I have a 5 speed, so I have more power off the line anyway than an auto so I don't need to mess with the intake. My truck has more power than I thought it would, and I never use it all, and barely put my foot down on the gas pedal. A Truck is for towing and hauling, not racing. Besides my favorite game is how much mileage can it get not how much gas can I guzzle to make the oil companies wealthier.
The 4.6 engine is still the same, the intake is not really part of the engine itself like rods, valves, cams, pistons, etc.
There are no mods to the 4.6 engine itself in the F 150, vs the Mustang.
Ford says they are no real differences in the engines (or specs, or the heads, rods, valves, cams, pistons, etc. etc. etc.) and that's good enough for me.
Long story short to the original guy - go with a good chip, but don't expect to get a high performance car from a truck.
That'll do it for me with this thread.

 

I wouldn't recommend a chip for a 5 spd, really all they do is change the shift points in an auto car. They're just not worth the money for what they do to just the engine

 

Remember the days when a truck had a three on the tree and all of them had either a big six or a small six...people hauled hay wagons and worked them like a dogf and they stood up to the test of time..

Now we have trucks that are like cars and we want more and more...I recall my Dad putting a 302 in his '66 F100 Fleet and that thing was crazy..and it had much less HP than my 4.6.....

Now we have supercharged Fords that everyone wants to make faster..

A truck is a truck is a truck....it will be a truck after you are done putting thousands of dollars trying to make it into something it is not...f you wa

If you want more power, there is only so much that little 4.6 can deliver...you will need to up-grade to a larger engine...

 

bolt on's are not crap i have seen a all bolt on mustang run a 12.1 its completely possiable i watch bolt on mustangs make vortech mustangs eat **** all day its all about a good driver and a good custom dyno tune
and the throttle body and plentum you can get a one in the same from bbk i thinks its called a bbk 78 you would just have to do some custom work

 

Jesus... where do you live that you get SHAFTED for almost 2 grand to do gears...

Around here gear swaps are 400 out the door parts and labor for a single axle...

If someone told me they wanted almost 2 grand for gears and labor I would just hang myself.

 

LOL... thats more the suspension doing the work than the bolt ons dude. Trust me...iv been around the block for a long time with the 4.6 and what it can do. If you want to spend all that money to get 40 hp... be my guest, especially with a vehicle thats a good bit heavier than a mustang. Plus most bolt ons will do nothing for the practicality of the truck; i.e torque. you will just gain unusable power in the upper rpms.

And the good driver comment is a given... if you give me a vette and you have a civic... and i just spin the tires of course you will win. But you cant honestly tell me that two comprable cars with the same driver...only one has 400hp and the other has 260... that you think the 260hp car will win lol... it will get pulled like a freight train. But lucky for everyone...driving is 99% of the battle.

And for a bolt on car, a "good custom dyno tune" means basically nothing.. all you can do is advance the timing until the point of detonation on 93 then back it off a tick, or lean the car out a tad. thats all they do. Its nothing special, lol. the best tuner is only going to squeeze out 10-15 hp from a bolt on 2v with out cams or any upper work... theres just not that much to adjust. Anyone who has done full bolt ons will tell you the only ones worth a darn are headers and gears.. the rest is all suspension on the track. I know people with 240 RWHP in the 12s with a solid suspension and good tires.

And ull get the same performance out of a 70mm tb and plenum than you will a larger one.. you start to lose significant intake air velocity without forced induction above that... hence why every manufacturer out recommends nothing but a 70mm for n/a applications.

 

If I wanna race something then I will use my motorcycle, if I want to pull or haul the family or other vehicles my 4.6 works just fine... I would like to have a little more pep but there is not that much difference in combustion chamber size than the 5.4.. Your getting a different cam, pistons and injection.. You can change anything you want and talk about how much it works and give stats, but until you are in a major magazine or online article because of the work you did. Well it don't mean ****.. You do what you do and discuss how it worked with your vehicle.. Thats like telling someone to try different anti depressant meds til they find what works for them..Every vehicle is different..
