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!
