i have never really compared 1/4 mile numbers. can a 4.6 with a computer chip match the performace of a stock 5.4? i have seen owner of 4.6 use this reasoning and i am wondering if any one has any real world experience. i would think it takes more than a chip to make up the cubic inch difference.

 

They are pick-up trucks.

 

I can't answer your exact question but will share what I have done with
my 4.6 Expedtion:

A good friend and I both have 2000 Exp's. He has the 5.4 with 3:55 gear
and I have the 4.6 with 3:31. Both are 2WD. Before I started modifiying
mine, we ran the two side by side from a stop for about a half a mile. He
had me from the start and continued to add distance between us the longer we ran.

I installed a flowmaster muffler to get some V8 sound. It did what I intended
but my friend continued to outpull me doing the same test mentioned above.

My next upgrades were adding a Superchip and Airforce One intake. The
results were excellent in my favor. I can now stay fender to fender with my friends 5.4 Like I mentioned earlier, I cannot say if the chip alone would have
netted the same results.

Another added benifit I see in going this route is a solid 3 mpg increase in fuel mileage over the 5.4

 

A similarly equipped 4.6l will run close to a second slower (maybe more) than a 5.4l. in the 1/4 mile.

 

LOGICAL please answer my following questions -logically of coarse

1. can the 1/4 mile performance of a truck be measured?

2. is a lightning , which by the way is a truck, as fast as mustang gt

3. is it not logical for a "performance chip" to add performace?

4. got any other useful information genius?

 

1) Yes, it's pretty much done the same way as with cars.

2) I suspect it is, but this wasn't a Lightning question was it?

3) Certainly that is what they attempt to do.

4) Yes, I do.....but how did you know I was a genius?

Geeze, relax...

I was just asking to clarify the question...read my post again with the question mark which I forgot to add....


These are pick-up trucks?

 

LOGICAL.. thank for a logical and stupid reply.

please answer the following questions for me

1. can the 1/4 performance of a truck be measured?

2. does a computer chip reduce the time it takes to cover the 1/4 mile?

3. can a lightning, which i think is a truck, keep pace with a mustang or corvette?

4. do you have any other useful information genius?

 

BROTHERDAVE,

The chip adds 26 HP to the 220 stock so you end up with 246. It adds 40 lbs/ft of torque to the 290 so you end up with 330. The 5.4 has 260 Hp and 350 lbs/ft of torque. The 2002 4.6 with 231 and 293 stock is closer with a 257 and 333. It is close but you will need more than the chip.
A 4.6 with a manual tranny wil put more power to the ground than a 5.4 with a slush box so I would favor the 4.6 under those conditions. Hope this helps.

Forgive me if I've asked you this before, but are you a fan of one of the greatest comedians that the South has ever produced? I saw 'him' live in a motel lounge in 1963(?) somewhere a long the east coast of Florida(may have been St. Augustine).

I dont know were the name came from. my dad and some of his friends have called me that since i was 5 years old. when i was little it really p!ssed me off, now i think its funny. i will ask him if that is where he got the name.

 

BDAVE- Aren't those the same questions reworded and reordered?

 

Just so you'll know; I'm talkin' about brother Dave Gardner. His records/tapes are still available at amazon.com. (Oh yeah, it was Cocoa Beach not St. Augustine.0

logical. for some reason when i posted the first response i got a message i had never seen and the computer took forever to accept it so i retyped it and sent it again so you are correct sir, they are the same questions reworded and reordered.

if your intension was to ask if i am refering to car and trucks , then i apologize. THE ONLY 5.4 that i now of in a car is the corbra r. seem like any time that i or someone else mentions making a truck faster, someone always pokes in and say why bother it a truck.

 

Wow, what a thread! Hot rods & believe it or not, more Brother Dave fans still live & breathe here on F-150 Online, I though I was the only one! We had every comedy album the Garder brothers ever did, I think.

Brotherdave,

To try and answer some of your questions, some of which you got other resposnes to already:

1.) You can run almost any kind of vehicle down the 1/4 mile, truck or car matters not, in general terms. Lots of us take our F-150's to the drag strip, including women. Like my own wife, she loves the drag strip, & we can't wait to get back out there with both our F-150's.

2.) To answer your question of can a Superchip bring the performance level of the 4.6 up to that of the 5.4, there are actually a couple of answers, as there are 2 different 5.4's, the 235 hp version from '97 & '98, and then the '99 & up 260 hp version. With the Superchip adding 26 hp to the 220 hp stock 4.6, that puts you ahead of a 235 hp 5.4 of course, but still a bit lower in power than a 260 hp 5.4. However, thanks to the other changes to the automatic transmission function from the Superchip, removing delays, retards, etc. in the transmission program, if both vehicles were automatics, in the 1/4 mile it would be very close to a dead heat. I have set aside for the moment the 231 hp 4.6 for 2001, assuming you get a 4.6 actually making 231 hp stock, adding 26 hp would bring it to 257 naturally, very close to the stock 260 hp version of the 5.4 motor.

These types of comparisons have been done many times here, and as you can see from other responses, the Superchip is doing it's job adding power. Sure, the 4.6 is a smaller motor, but when you put a decent tune on it, which the factory does not, you pick up obvious power from the same displacement. It's very easy to make a 4.6 F-150 outrun an identical 5.4. With more cubic inches, you can always make more power, but having less cubic displacement does not mean you cannot increase performance by quite a bit. Put another way, it's all a function of cubic $$$, as just about any vehicle can be made to perform every bit as fast as it's owner wants to spend.

I hope that info helps a bit,
