what's changed???????????????
- Thread starter page90lx
- Start date
did you take both to the track? it may just feel like it's faster. there shouldn't be any sizable difference between the two in power.

I can't get it up......ok that didn't sound right.
It could be that your 2001 isn't "new" anymore and the 2004 is. Just a thought. If you take good care of a vehicle, it should good, no matter how old or how many miles it has.

Waterpump pulley different yes? (stupid rib)
the color of injectors? (been debated on injector size)
04 no Fning schrader valve.stupid ford
If you had an early 01 the tranny? (don't see how that would make a diff)
Maybe the 04 has different rear gears than your 01 ?
04 still in tip top condition 01 had some miles? (although usually a car runs better after a few thousand)
The o2 location is different on 04. (don't see how that would affect performance)
Cleaner fuel filter?
Or maybe 04's are just better. j/k

I'm guessing that its the placebo effect. The new shinier pill must work better than the older model.
That, or you may have just stumbled upon a factory freak now, or a mediocre car before.

I have tried to take most everything said into account . but i take care of my cars and the 2001 only had 22,000 on it when traded and the 2004 is faster than the 2001 and it was stock at the time. somtimes you just find a car that has a little more to it than the others a.k.a. lucky. thanks for the help guys i know now i didnt miss anything

I think I have that same problem...

I don't buy into this thinking. These motors are mass assembled. Where does this 'factory freak' factor come into play? I mean, where is the horsepower hidden?Gearbanger 101 said:
You may see a couple horsepower difference, but I wouldn't expect to see anymore than that.With regard to the original question...I too think it's old vs. new, just feeling faster than the other. Plus the fact that the 99 is probably in need a bit of maintenance to bring it back close to factory fresh.
Tell that to the guys with the Fox bodied coupes that were cracking low-14's/high-13's right off the showroom floor back in the day.twogts4us said:
Assembly line tolerances, changes mid-year in materials, product suppliers, quality care can all have a large impact on how a vehicle performs. I agree that the differences aren’t as huge as many make it out to be, but it does at times happen. I used to work for a Ford Dealership and was Assistant Manage for their Budget Rent-a-car division. Trust me when I say we used to put these cars through their paces when transferring them from one area to another. We'd often line up the exact make and model of car with all the same options and almost every time one was noticeably faster than the other.
Why would you trade a 2001 with only 22,000 miles for a 2004? All you're doing is eating the depreciation to get a car no better than the one you had.page90lx said:I have tried to take most everything said into account . but i take care of my cars and the 2001 only had 22,000 on it when traded and the 2004 is faster than the 2001 and it was stock at the time. somtimes you just find a car that has a little more to it than the others a.k.a. lucky. thanks for the help guys i know now i didnt miss anything

This has nothing to do with the question, but more to do with driving style. (How to drive it like you stole it - 101) I'd guess you are referring to different magazines reporting different ETs. Some mags will drive it like they own it while others will drive it like a rental. Guess who got the low-14's/high-13's?Gearbanger 101 said:
The assembly line tolerances? Especially with modern engines, it is essentially set in stone. There is little that one assembler can do to make it better than another. Changes is materials? The only significant change in the 99-04 Gen2 SN95 run that significantly affected performance was the change from the T-45 to the TR-3650. Product suppliers? Same answer...no significant changes. Quality care. I think you'd find more issues with interior fit and finish, body work and issues with exterior trim pieces than anything else. And, IMO, it is highly doubtful that you find any of the above on a Ford that was above par. And you certainly wouldn't find an above par motor...maybe a below par one, but not above. Again, all just my opinion...not trying to argue with cha Gearbanger...just a friendly difference of opinion.Gearbanger 101 said:

“I’ll take any car you’ve got, but the one that was built on a Monday or the Friday before a long weekend”?
…..I don’t mind a friendly difference in opinion, but there’s more to it than driving style. How else do you explain the multiple instances when we used to take out Taurus’s, Contours, Focus’s and other gutless wonders, line them up from a dead stop, nail the pedals at the same time, achieve no wheel spin with either car, and still have one repeatedly pull significantly harder than the others. No, it wasn’t always like this and for the most part they all perform relatively the same, but it does happen. Maybe one was broke in a little differently than the other, maybe the parts in one engine were of a little higher quality, or assembled with a little more care than another, maybe one cars MAF and/or computer was calibrated just a little more aggressively than another because of a drop or raise in temperature that day. The point is, is that it still happens. As far as changes in materials…it can go a lot deeper than just the model of transmission the particular year car used (but yes, that is a good point). Maybe the assembly line that knocked off the 4.6L pistons that day had a little higher silicone content allowing for quicker expansion and better sealing? Maybe the plan where they pour the head castings used a different set of moulds than they did the day before. We already know that core shift can have a huge effect on how a head flows (remember the instances of raised compression because of the casting flaw the ’01-up heads had over the ’99 and ’00 models?) ….and they’re not that perfect with today’s engine because I just removed a ton of casting flash from the 2001 Romeo heads I just ported. Yeah, all of these differences may be minor and insignificant on a normal basis, but obviously the make some difference, otherwise we wouldn’t have such inconsistent performers. I mean…a bad tank of gas here and there is one thing, but I’ve seen far too many Mustangs (and cars in general) that have been fire breathers or dogs right off the showroom floor to just chalk it up to coincidence.
But that’s cool…..I can easily see it as being a few sub-par vehicles adding to the masses. I’m sure it works both ways.

Different MAF, injectors, compression ratio, block, eec strategies. Not that these contribute to the factory freak idea, just pointing out a few changes that were made other than the trannies.

Damn. And I was just going to say that out of the pack of popsicles that I bought, some had more kool-aid in them than others.
. Kids ya knowThe above statement is very true. That's why sometimes even some Diehard batteries are garbage going out the factory door. Even though they all come down the same line, some are better than others.
I used to work in a plant that made batteries. And I can tell for a fact that we sent out some crap, even though the batteries came down the same line. Some batteries had more charge than others. Even though a machine was set to pour out a certain amount of lead, sometimes it poured more into some batteries than others. There are only a few components that make up a battery and they had variances. So just imagine an entire car and all of the variances that it has. I guarantee you, if you tested all of the Trick Flow heads that were made a certain day, some will outflow others.
Plus you have to look at the one important human factor when working, "Break time."
I have an 02 and my fiance has an 04. We have the same 3650 tranny, but our 1st and 5th gear ratio is different.
jimfitzgerald said:True, but you already had one.
Yes i did but i didnt like the color
and i was able to get adeal i couldnt pass on and then there was the all important female factor the 2004 is really hers i just work on it, mines the 90LXwe bought new somtimes you got to do what mama wants
