    Stock? Modified? If you taken your Fiesta ST down the 1320 we want to hear your times. Post 'em up. Bonus points for time slip images.

    If you're a newbie with a question, ask. If you're a drag race veteran with some tips, share 'em.

    Also, since the car is new to market, feel free to speculate on estimated times too.

    I'm hoping flat 15sec
    Can't wait to see what I'll get when I get mine.

    There were a number of missions for August for the Fiesta Movement to run the Fiesta ST on a drag strip. Oddly, there were no takers.
  5. Why would that be? Lack of skill set? Lack of track options? I'm just learning about those "missions". Can't believe a 1/4 time hasn't been seen yet for regular joe. Anything sub 15 should be OK. It's not a 1/4 car anyway.

    Not sure, I figured somebody would pick it for a mission. There are a ton of really good missions that don't get picked. Everything from racing at famous tracks, SCCA autocrosses, Skip Barber school, and top speed runs. Those of us who really want to do those missions are the ones that usually have killed their tires by now and can't do those kinds of missions. Agent67 and I are two of those agents.
  7. I looked on this site and didn't find this:

    Won't bother mentioning the lack of driving skills. Oops, I just did. No matter, glad someone was able to get to the track with a new Fiesta ST.

    that is one slow 197 hp, 2500 lbs car ;) my pre-Fiesta 124 hp, 2400 lbs car ran 16.2 in the quarter mile. but seriously the specs listed in that article have the specs wrong. The Fiesta ST curb weight is 2742 lbs. A non-ST Fiesta is 2537 lbs. Also the Fiesta ST compression ratio is 10.0 to 1, not 10.5

    I think it's the brakes on the "vectoring" to combat the torque steer that slows 1 and 2nd gear down. You tune that out and put a good differential in the front and you'll get better times even at the same power.

    the enhanced torque vectoring control should not affect acceleration in a straight line.
    Enhanced torque vectoring control is
    comprised of two elements:
    • Torque vectoring control which applies
    brake torque on the inner wheel in a
    curve for better traction and less
    • Cornering understeer control which
    controls the yaw response of the
    vehicle under braking and acceleration
    on high and low friction surfaces.
    No action is required to activate torque
    vectoring control. It operates automatically
    due to vehicle operating conditions.
    Unlike electronic stability control,
    enhanced torque vectoring control does
    not slow the vehicle but does help control
    excessive wheel slip and gives the vehicle
    cornering agility. The system only increases
    performance. Because of this, enhanced
    torque vectoring control is not disabled
    when the AdvanceTrac system is off."

    I'd like to see a comparison of it turned on and off with a proper differential. Has anyone one the focus st side done a comparison like that yet?

    Hello guys, my name is Daniel Arroyo and I am a Ford Fiesta Agent from Tampa, FL. Temp was about 85 degrees (7pm). Here is my best time slip, I also have footage (I just need to edit it). I hit 15.200 @ 93.16 mph.

    That's pretty good.

    One of these days some one is going to figure out how to make one really hook and get the 60' time a lot lower. Add in some cool air and low 14s might be possible.

    I want to add enough power that I could run solid 13s (if I was any good at the track, I've never tried because I don't have a local track).
  15. No offense, but you're going to need quite a bit more HP to get solid 13's out of this car AND having never been to a track. The car magazine drivers aren't the best and they hit 14.9 so far. A "good" driver could probably hit 14.7 at best in great weather. Sub 14's needs another 50-70HP I imagine. If not more. Plus a good driver. A 13.9 1/4 mile won't be easy nor cheap with this car.

    What saddens me is my neighbor back in 1987 drove his stock GLHS 14.4-14.5 consistently at the track. I know it's a lighter car, but for sure with less HP. 26 years later our hot hatchbacks still can't match that 1/4 mile time.

    I said if.

    I'll be happy with the power even if I'm not good enough to hit the number and I probably won't ever run a drag race suspension setup so it might be stuck in the 14s.

    As far as what it will take, I think 270 to the wheels should do it and that will probably take a bigger turbo, possibly a new cam to get more fuel out of the high pressure fuel pump, a nice intercooler, custom exhaust from the header to the tail pipe, probably a free flowing intake (maybe a bigger throttle body) and an Accessport with one hell of a tune.

    I might get some lag in the bargain but probably not too bad.

    Time and money are the only things that can stop me and as of now time is more threatening.

    I've read several times that the stock turbo is tiny.

    If you follow this link:

    You will see in their maps that torque tapers off as rpms increase and it says the boost target is 20.5 psi peak tapering to 13.5 psi at redline.

    Looking at the torque curve, I believe it.

    To me that sounds like the turbo can only pump so much air and at high rpm the boost falls off because there isn't enough flow to maintain the pressure.

    If I can get a turbo that holds on to 20.5 psi until redline, I estimate a 25% increase in power from 180 to 225 whp.

    If I can add more boost or find power from a free flowing exhaust, intake or upgraded intercooler, I might find 250 whp fairly easily.

    The high pressure fuel pump is a Bosch and it looks like they only make one kind. The volume is determined by the number and height of the lobes on the fuel pump cam, worst case I'll need a billet cam and I'll wind up with a fuel system almost exactly like a Focus ST. I don't know if injectors will be a bottle neck but if they are, maybe the Focus ST will offer an upgrade? Focus ST fuel system supports 300+ whp so I'll be good if I can emulate that.

    I figure a budget of $5,000 should get me close to my goal and even if I get stuck at 230 whp, it will still be knocking on the door of 13s with the right driver and suspension.

    Im definitely going to have to agree with "Wash" on this one, I only took it down the track three times and consecutively pulled 15.200 then 15.223 then 15.4. The wheel hop messed with the launch a bit I would suggest dragging the clutch a little bit rather then dumping it because it helps deal with the torque (FWD), if I had a couple more runs (and less people at my track) I know I could get 14.9/15.00. The turbo on this car is very small and it helps with the fun factor to the powerband, but if you just got bolt-on's, tune, and stickier tires I am pretty sure I can dip low 14s to high 13s. The only problem I see with this car is the gearing (1st/2nd, very short), after some practice if you are a great driver (feathering for traction, keeping the RPM within the peak hp/tq curve, and compensating with a slow clutch dump) im sure you/I would get high 13s. The drag strip really doesn't matter in terms of the ability with this sort of car. It is beautiful on roll races (Straight line) and it shines within all it's glory on twisties. I also managed to beat two Focus ST's which I found odd. (maybe they didn't know their cars well).

    At the autocross test and tune I ran, I had several chances to try different things at the launch and I was paying attention to it about 6 times. The "track" was not too bad, cracked up but pieces were not getting pulled out. The launch rpm is hard to pick, too high and it spins through first until you shift, too low and you bog (I do that a lot on the street). Then there is the clutch release. I think I was happy with 2-3 launches.

    With a stickier track it would put down more power and I think I could do that with a little practice, I just worry about the reaction time, staging and all the other details.

    Also my idea of solid 13s are more like 13.6 or 13.7, quick enough that an error can add a few tenths and it still runs a 13.

    DanielArroyo New Member

    I totally agree, I actually really like the clutch while driving on the turns, it's really mid/late with a few inches of play, you need some delicate coordination within it's delivery. This error alone can account for a drastic change in times. But what would your potential setup look like all around to achieve the 13s with ease? I would love to see a slightly bigger turbo on it, 3rd is gold in this car and 4th struggles in it's powerband. Tires, Full Bolt-On's, Tuned, w/ slightly bigger turbo, fuel, and Suspension would make this car a monster (250whp-300whp), it's already feather weight.

    15" front wheels with slicks as tall as you could fit, possibly an anti-sway bar delete, drag shocks with low rate springs and pizza cutters on the back.

    A splitter might help but I'm not sure if its worth very much on a car in the 13s.
