Ford Mustang: Expected performance of stock `03 GT Vert ? Road tests? Dyno charts?

    Expected performance of stock `03 GT Vert ? Road tests? Dyno charts?

    Hello,

    Can anyone tell me what a bone stock `03 GT convertible will run in the
    quarter? 0-60?

    I have not yet found any road test articles on the GT convertible
    specifically. The convertible is about 150 pounds heavier than the coupe I
    believe... I assume that is the only performance related difference between
    the convertible and coupe.

    How would you describe the torque output of the GT 4.6 across the rpm band?
    Is this engine torquey down low, or does it concentrate the bulk of its
    power at high rpm? I have yet to see a torque curve graph of the GT 4.6 -
    is there one on the web someplace? Any dyno charts anywhere for a stock GT
    4.6?

    I have not yet driven a GT 4.6... I did drive a V6 Stang Vert for a day and
    fell in love with the car itself, though I felt the engine was way too
    weak... (my friend's stock 4-door Honda Accord 3.0 V6 would blow the doors
    clean off it). I can't wait to get my new 4.6 Vert next week.

    My last car was an old 455 Trans Am, so I am wondering how happy I will be
    with the 4.6 GT? I don't expect it to embarrass the 455. However, being a
    lighter car with modern engine technology and better gearing, I do expect it
    to kick some butt.

    One person told me that I should expect the GT Vert to run high 14's in the
    1/4, and 0-60 in about 6 seconds flat. Does this sound right? Regardless
    of the numbers, I am hoping that the GT is torquey down low so it provides
    good kick when just driving around town. I enjoy feeling a lot of torque at
    lower engine speeds. Comments?

    Thank you -dm

    dm,

    0-60 in 6 seconds is pretty fast.. I don't know if the GT will be able to do
    that. Either way (and this applies to the quarter mile, etc) it's not only
    the car that determines the speed. It's the person behind the wheel that
    matters also. It's hard to give an actual figure of what YOU'D be able to
    push since I dont' have a damn clue how you drive =). I have a 98 Mustang GT
    & she pulls her weight around nicely... even nicer when I put 3.73 gears put
    in. Anyway... maybe someone will be able to provide you with dyno charts
    though if they've had their cars dyno'd. I haven't... and I don't have an
    '03 GT, but they are damn nice cars. I've test driven a couple.

    Hi Mike,

    Thanks. Surely things like driver skill, tires, road and weather conditions
    etc will effect actual performance times. I'm not really too concerned with
    the exact times that I personally will be able to yield with the car, but
    more interested in what the average performance results are for these cars
    to use as a basis for comparison.

    You mentioned that 0-60 in 6 seconds is pretty fast. I'd agree. But I read
    some articles recently stating how guys have been yielding low 5 second 0-60
    times in new Mach 1's and mid to low 13 second 1/4 mile times. I realize
    that the Mach 1 coupe is quite different than a GT Vert in terms of
    performance capability. I guess reading about the Mach 1 got my hopes up.
    I wanted to buy a Mach 1 very badly, but they don't make Mach 1 verts... and
    I had to have a vert... so, the GT vert is the next best thing. A Cobra is
    just too much $$$ for me right now, plus I am not really a supercharger
    kinda guy. I've run normally aspirated engines since day 1, and I think
    I'll keep on this path (not that there's anything wrong with superchargers.)
    I've always been a believer in cubic inches... my last car had a bored 455
    (462)... that's about 7.5 liters (compared to a Stang 281 / 4.6 liter). For
    this reason I am wondering how happy (or not) I will be with my new GT vert
    once I get it. Well, the Stang will yield at least TWICE the mpg of my old
    462, so that's a pretty big factor, especially at $2.00 per gallon now.

    My friend's old G.T.O. vert was always fun to drive, felt plenty "fast", at
    least for street use... I think he averaged about a mid to high 14 in the
    quarter on street tires (car was very heavy). So... I guess if the Stang GT
    vert can yield similar times in the quarter, I'll probably be happy (maybe
    not thrilled to death, but at least happy). I never actually timed my 462,
    but I did blow away the above mentioned G.T.O. plenty of times on the
    street... I was probably running a low 14 or high 13 (in a heavy car with
    street tires). The best thing about that car was the torque on tap... at
    almost any rpm in almost any gear at any time, you could stab the pedal and
    damn near snap your neck... that is if and when you could keep from spinning
    the tires which was a task... the thing was TOO torquey. Was a beast
    really. I expect a more refined vehicle overall from the Mustang even if it
    isn't a brute from hell. These days I've been getting more into "quality
    verses quantity" anyhow. Just wondering how much "quantity" (of power) the
    Stang really has. Thanks

    Well, with a 455 Trans Am, you had the top-of-the-model-line-up for
    Firebird in terms of performance.

    You might want to look into the top-of-the-model-line-up again, which for
    Mustang, would be a Cobra.
