it's a choice of either the diablo sport chip or a cat-back exhaust. i plan to eventually have both in addition to a stage one aerocharger.

or maybe i should consider another choice for a first upgrade?

thanx.

the chip would be a waste with the ACI. Just get a nice exhaust and start saving for the ACI, or forego the exhaust and just get the ACI, since you will already be pushing the transmission past its limits with the ACI

yeah...i know the turbo will be almost too strong for the tranny. at two grand plus cost of install, the turbo is less like a goal and more like a possible dream.

assuming i could not get the aerocharger, should i go for the diablo or cat-back? i understand that the chip does wonders for the auto tranny. then again, cat-backs are sporty and (possibly) add up to 5-7 whp.

thanx. i'm still open to other suggestions for a first mod. what would you do for less than $400?

well, i've been searching for dynos on google and found this. IE users, press F11 to enlarge view of dyno sheet.

judging from the whp, it's a manual. it has a new exhaust (no idea which), new wires (which mean nothing), pulleys (assuming a udp), and the diablo sport chip. with those mods, there's a whp gain of 6.6 and 4.4 ft/lbs of torque. the run was done september 21, 2001. also, i think this took place in canada. maybe the canada version focus has different specs? maybe diablo has made further improvements to the chips programming since then?

i hope so because these gains suck. i shouldn't be surprised...aerocharger is looking more like a reality.

for anyone following this, here's another dyno (one example--click on steedadynoB.jpg) i found at focusfrenzy.com. it's a clear base line comparison of stock (103 hp) vs. chip (110 hp) vs. chip & cat-back (116 hp).

okay, if I couldnt do the ACI thing at all I would go for a chip and some under drive pullys, for one they won't attract ANY more attention to your car by making it louder, and they'll give you some nice noticable gains for LOW prices, I got my Superchip for free for my auto, and sold it for $75, they're very inexpensive if you get them used


another thing you should look into is a complete bushing kit, and installing it yourself, or atleast do the motor mounts, there's alot of reponse to be found there with the small sacrifice of vibrations....

all of those are relatively cheap, and effective mods...I wouldnt do an exhaust unless you just wanted to make your car sound a little sportier...and even then I would try to find a used one

You might want to consider a plate-style trans cooler, synthetic fluid exchange and a remote trans filter re-locater.
Trust me, if you drive your car hard this will help prolong the life of the poor 4F27E.

does anyone know or believe that a chip can really add hp & tq to a stock zetec?

Do something for the intake before the exhaust!
intake before exhaust? i thought the typical gain with an intake mod is between one and two horses. freeing up the exhaust usually adds at least three more ponies, right?

more to do with driving style than anything. Dont try the numbers game too hard with these initial mods. I like Lowend torque, lot more useful for incity driving...which is wher emost of us do most of our driving.

Exhaust will net you no gain to a loss in low end torque, while an intake will help all the way through, but most pronounced in the lower ranges.

UDP's are awesome as well; they improve how fast the car revs as well as free up a few HP lost to accessories.

i'd honestly go for either the volant or iceman intake...or an underdrive pulley.

i recall when an underdrive pulley, best bang-for-the-buck, was alomst always the first recommended mod. after doing a search (hold the applause
), i found claims of 7-8 hp. i'm gonna guesstimate that to be around...4-5 whp? good suggestion, kenna j.

i also found additional info (again with the searching) regarding the gains of a chip--a steady 2 horses throughout the entire rpm range? right on!

if there is still a focaljet member discount at 2-D's Performance for the diablo sport chip...then i think these two mods done at the same time would not only leave a decent butt-dyno impression, but i'd still be under my $400 budget. awesome...thanks, guys

i thought that loss of low-end tq with a larger exhaust was a myth?

i'm not saying it'll be too noticeable, but physics is physics. Most peopel agree that the high-rpm gains morethan make up for the low end loss.

i'd strongly caution you ont to bother with a chip on a mostly stock engine...just not worth it. I dunno, surprised not to see more support on this. but between the modest gains and the need for premium fuel not worth it.

As for using the chip to firm up shifts, something some of use slushbox users have bought and succesfully used is a device that regulates the shift firmness by means of a potentiometer. I'm too lazy to search but I read about it couple months ago. They bought it through escortfocus.com

UDP/Intake/shift controller is how I'd go, dude. SEriously reconsider your decision to get the chip.

i'd shy away from a chip right now, not that it wont work some and work as you do more, but b/c of gas prices these days (havin to run premium w/it). look elsewhere 1st, i/e is the logical choice.

if you consider gas prices a reason, then yeah, shy away from the chip, but if you regularly go on road trips, or long trip on the highway, then the chip is a plus for obvious reasons....I know the Superchip only changes the first gear shift points, but the change in firmness and the small timing advance is definately worth it.

but you guys are definately right, the escortfocus.com mod is definately worth while if you want to keep from having to run super unleaded

well, it just so happens that premium gas prices don't concern me. and, i drive 272 miles (both ways) about every other weekend to visit my girl at college. if the chip will also give the engine a bit more driving zest--then i'm sold. anyone know if 2-D Performance still offer the focaljet discount? i'm confident this and the AF/X UDP will be my first mods.

judging from dynos (one example--click on steedadynoB.jpg) and info shared on this forum, i'm estimating an 8 to 10 whp gain with the chip and af/x udp being my first mods. does 10 whp sound realistic?

okay...
maybe i'm way off. would 5-7 whp be a realistic gain with these two mods? my goal is to find the best mod for an automatic costing less than $400. any ATX drivers out there have experience with these mods or other ideas?

thanx.

Don't waste your time with a huge high flow exhaust setup, because you will lose too much low end with a mostly stock Zetec - beleive me
.
Your best bang for the buck mods with your setup goes like this:
Diablo or SuperChip - (you need to make that auto shift better! also the increased line pressure will prolong transmission life)
Poly motor mount - (makes up the "off the line snap" that the automatics torque converter soalks up
)
UDP - (this will provide you with gains all around, and again makes up for some rpm lag from the automatic transmission)


This is of course all in my opinion with my auto Focus.
If I had to do it all over again those would be my first three mods.
