Ford is saying it's faster with the the automatic, no loss of performance and faster shifting!

Automatic will be more consistent and faster, but less fun.

Same to me as driving a train. Put in the key and push the shift from stop to go. What the sports car in that? :p

My guess:

3.73s. 12.6 to 12.9. 0-60 4.2 to 4.5
3.55s. 12.8 to 13.2. 0-60 4.4 to 4.8
3.31s. 13.1 to 13.5. 0-60 4.6 to 5.0

depending on driver weight and weather

Well like I said I've had lots of clutches and hit and missed lots of gears, blown out a rear end or two and had lots of fun! But Arthritis in the knees and not wanting to manually shift through 6 gears has sent me to an Automatic and I will enjoy the hell out of it!

Stick shift is gonna be the faster one. Probably .3 0r .4 tenths and 1-3 MPH in the 1/4 mile over the auto.

I saw it's (6-Speed) numbers in Motor trend 12.7 @ 111 MPH. Wow!

Last week I used a GTech Fanatic SS accelerometer to check my 0-60 and 1/4 ET and TS. This device is similar to the instruments used by most road-test magaines, so it's a good yardstick for measuring your performance; it's a simple GPS that attaches to your windshielkd with a suction cup, and can therefor accurately compute any time/distance formula by means of satellite tracking. Unfortunately, I had to send the $200 device back to the mfr. when it stopped working, probably my fault for dicking around with something I was clueless about, so I have no photographic evidence of the results. I will be sure to take pictures of the results next time around.

However, I dd get off three clean 1/4 sprints on a local deserted roadway which had a mile-long well-paved straightaway.

Note: My 2011 GT has the 6-speed automatic, Airaid CAI and Bama "Performance" 91 octane tune. Stock tires, 3.15 rear end, Hushpower mufflers, nothng fancy.

First run I came to a complete stop, pushed the "ready" button which does not start the timer until you begin to move, and floored it in "Drive," Traction Control on.

The GTech Fanatic reported a 0-to-60 time of 4.6, 1/4 mile of 12.7 @115 mph. Lots of fishtailing in first two gears, but far less than at Mason/Dixon dragway where I turned 13.2 @109 (and that was before installing the CAI).

I did second and third runs in short order immediately after the first, and each successive run was a little bit slower, which suggests that letting your engine cool down between runs may improve your times. The engine showed absolutely NO signs of distress, continued to idle at a steady 800 rpm, temp gauge straight up.

But we must also take into consideration that I was trying different launch techniques. Second run (it says here on the notepad I jotted numbers down on), I launched more gently in order to control wheelspin, gradually leaning into the throttle as I picked up speed. I think I leaned into the gas a little too gently, resulting in a 12.8 1/4, can't read my writing on the TS, but it looks like 109 mph.

Third run I split the difference in launch techniques, limited the gentle throttle to about a car-length, then stood on it. The launch felt good, there was a little loss of traction going into 2nd gear, and then the sucker hunkered down and really picked up speed -- ET was 12.9, but the speed was up to 118.

Again, this run was made less than two minutes after the previous run as I was kinda pressed for time as church was gonna let out and clog my little public raceway with drivers who HAVE been struck with the fear of god.

I was trying to get the device to pull up my previous scores (it also measures G-forces and 60-0 brake distances and I did rip off a dandy 99 foot 60-0, but I don't think that's repeatable) when I did something that caused the device to fail to operate. I sent it back to the mfr after a phone call.

Anyway, this is great performance for a lightly-modified Mustang. When I first joined this group I was grousing about the magazines getting better perfermance numbers than I did at the track.

Now that I've used the GTech SS, I know how they did it. So now that we're comparing apples to apples, my little Mustang ROCKS!

I am very impressed with these numbers! Makes me wish I instead, got the automatic, but nonetheless, I am very happy with my Mustang. I very rarely get on mine because every time I do, I get that guilty feeling like I "abused" it. I never powershift or powerbreak - just get on it and shift fast and inadvertently albeit moderately hard. I got on it yesterday and I believe my tires were a bit wet after a wash, but I was skidding through first and second. When I went to go into third, I hit 5th instead; oh well. Anyhow my first upgrade will be the Airraid CAI and a bama tune too, which I hope I'll be able to feel. :hihi:

My main reason for getting the automatic was my buggered-up left foot, mangled in a bike accident a few years ago. But after racing with stick-shifters at the Mason/Dixon during a couple of "run what you brung" tuning afternoons, I found the automatic was much less hassle. No fried clutches, missed shifts or jammed linkage. Just point and shoot, the big issue is whether to start with one foot on the brake and how much throttle to come off with. Once launched, let the auto do he work, with the Bama tune the engine will redline in third and fourth, but not the first two gears, I think that's the Traction Control doing its thing. I've tried launching with the TC off, too much wheelspin with stock tires, slicks would dramatically improve my times, maybe get me into low to mid 12s.


The MT allows more control over wheelspin, no doubt, but shifting is still kinda hit-or-miss under pressure, and a lot of drivers baby their trannies in order to be able to drive home, and they lose valuable tenths because of this.

I was a stick-shifter for years, and quite good at it (I like to think). But modern automatics are so good that anyone considering a new or late-model performance car should test-drive both auto and stick before deciding.

And all that being said, the Airaid/Bama combo ROCKS!

JMHO
