2.0's to the sixty foot make sense with a stock converter and is actually decent (an aftermarket converter would improve that by at least .25 second assuming traction).

What I (and Gene K) are trying to point out is that the 1/4 mile trap speed is way off from where it should be and the timers at the track were probably not placed correctly. The 1/4 mile ET totally makes sense, but that is checked by a seperate beam at the actual finish line, while the trap speed is calculated by two seperate beams to average the speed from 66' before to 66' after the actual finish line. I suspect that those two beams were inadvertantly moved too close together, erroneously showing less time to travel between them and, therefor, inflating your trap speed. The car in the right lane appears to have suffered the same inflation of trap speed as a 104+ trap speed is indicative of a low-mid 13 second run - not a 14.41 pass.

I also can't help but notice that you were going nearly 88 at the 1/8 mile. My supercharged '07 GT averages about 89 to the 1/8 mile. I suspect that my centrifugal supercharged 4.6L (which has about 40-50 more hp at the flywheel than an '11 GT) should pull harder than your 5.0L - yet, I typically average about 111-112 mph in the 1/4 mile. I find it hard to believe that your heavier, less powerful N/A Mustang could beat me in trap speed (by 3-4 mph) from the 1/8 to 1/4 mark.

Again, the 115 1/4 mile trap speed just doesn't compute. All the other numbers on your timeslip totally make sense and the '11 GT (manual or automatic) is one helluva beast.

Take the car to another track and get this over with.

This is entirely believable. Go check out what Challengers run over at ChallengerTalk - R/T automatics are routinely running high 12's to very low 13's, while 6-speeds are nearly .50 second behind. Automatic R/Ts (no, not SRT8s) typically run very low 13's, and with a tune, muffler/mid pipe/and a techicallyacoldairkit and good air, high 12's are pretty common.

Remember the amazement when the 5-speed autos appeared in the new Mustangs and were nearly spot on with the 5-speeds? This isn't a slushy AOD-E that hamstrung a Mustang like in the past.

Manuals though are going to be more manageable in an auto-cross and unless there are timing lights at stop lights with a scoreboard, a lot more fun and you look 84% cooler nailing a 2-3 upshift.

People are talking about the trap being wrong, not the ET.

i would disagree. First off the car on the other lane was running a 2.5 60 ft. so he burned rubber off the line, its usually .2 for every .1 drop in 60ft, if he would have pulled a 2 sec 60 it would have been a 13.4 @ 104mph which is an accurate time basically what a stock 03-04 Mach 1 would run.

Comparing the 1/8 to 1/4 from your car to the stock 5.0 is wrong since you are running drag radials, your launch to 1/8 is going to be better but the 5.0's power shows up and runs you down from the 1/8 to the 1/4.

One more thing, I do agree 115 is higher then i would expect and would like to see timeslips from a few passes. But I don't feel it is off as much as you feel to believe.

sdsguy

maybe one of the new features is a flux capacitor and once the cars hit 88mph they travel even faster than described!

Exactly i will be heading to a different track this coming week to see if the MPH is truly accurate. I myself was surprised with the MPH but in the same area every other car there was in the right MPH and i did both passes in both lanes. So in essence whenever the track officials saw my car they decided to move the beams a little

I just returned from a road trip (Dallas to Austin and back) with my 2011 Mustang GT Premium 6-speed auto and want to add my experience to this discussion. Two things I'm very impressed with: 1) The automatic has enough gears to put the engine in its "sweet spot" no matter what the car's speed -- and put it in gear QUICKLY!, 2) The 5.0L low-end torque is miles ahead of the 2010 Mustang GT's 4.6L.

I've also owned my share of Cummins diesel pickup trucks, so I know what real torque is. Not saying the 5.0 is anything like that, but I've been amazed at how well the new 5.0 pulls from low RPM. For example, in easy driving, the automatic may shift into a higher gear and lockup the torque converter which drops the RPM to 1,000. Even when going up a hill, the engine will easily pull and accelerate the car from 1,000 RPM with no sensation of lugging, pinging, or any type of complaint. That is amazing considering this engine's performance, RPM range, and 11.0:1 compression. My 2010 Mustang GT 4.6L manual 5-speed would not do that. That engine was relatively gutless below 3,000 compared to the 5.0L.

The 6-speed automatic will quickly gain more respect when there are more of them out there and folks see for themselves what it can do.

Lastly, the 2011 Mustang GT is one helluva car. I'm not just speaking of awesome performance, but also quality of workmanship, quality of materials, design, style, it's the complete package. I'm still in awe of the car. It's the real deal.

My car has a centrifugal blower which makes its absolute best power up top. My car's strong point is from the 1/8 mark to the 1/4 mile mark as I'm making full boost by then. There is no way a heavier car with 40-50 less hp is going to gain more mph in that stretch than my car. I gain about 22-23 mph from the 1/8 mile mark to the 1/4 mile mark, on average. I suspect that a new 5.0L automatic could gain 20-21 mph in that same stretch, which from the 88 mph at the 1/8 in this '11 GT's example would yield 108-109 mph at the 1/4 mile. 115 just is not likely. And again, I have no qualms about the 12.76 ET. That is right in line with the hp & weight of the '11 GT. I do agree that we need to see a bunch of other timeslips from a variety of '11 GT automatics to know for sure.

All-Or-Nothing

I think the Automatic cars will be very very fast with higher stall converters. Is any one developing them at the moment.

Look what evo just ran NA!
Evolution Performance, Inc. First 2011 Mustang GT 5.0 4V In The 10's N/A - 10.97@ 124MPH - 1.49 60ft

All-Or-Nothing

Hmmmmmmmmm...........this time would make it faster than all the N/A Camaros on C5. In fact it would be #6 on their power adders list.

guest01

Looks like we have our answer as to whether the 2011 6-speed auto Mustang GT can do 115MPH in the quarter. Evo Performance ran a 117MPH (11.98) with their 2011 auto ...and with no power adders (only a CAI and tune, and some suspension/tire changes).

==========

Six hours ago, Evolution Performance reported on their facebook page: "First Automatic 2011 Mustang GT 5.0L 4V in The 11's - 11.98 @ 117 MPH N/A! Grabber Blue FTW....!!!!"

Only Suspension Mods were Steeda Ultralite Lowering Springs and an Evolution Performance, Inc. Adjustable Panhard Bar! Track Temp was 127 Degrees and the outside Temp was 93 Degrees! The Car was Full Weight, 19" Wheels on the Front with 18X9" Wheels On The Back with M/T Drag Radials. CAI, tune and lt's

This weekend Same track, Sacramento Raceway i pulled a 12.57 @ 115. Still all stock just learning how to launch with the stock 235 tires. The auto times are coming in and finally backing me up

WOW guys this is great news.

Holy crap these auto's are fast from the factory. I thought it felt fast even accelerating from highway speeds, this just confirms it. I've never been happier that I got an auto.

Hey guys, I asked this on another thread.- no answers

Is any one with an auto(50.) getting any engine "ping"? I had it off and on driving back to Fl. from Pa. and was using only 93. - even with moderate acceleration. At first I thought it was mountain elevation, but I also notice it at lower levels. Think maybe the sensors or computer is having a hard time figuring out what type of driving I'm doing? Or maybe not all these stations are selling the same octane?

2,000 miles on the odomoter thus far, no problems with my '11 GT 5.0 auto. I use Exxon 93 octane 10% ethanol. I don't know if heat has anything to do with it or not, but it's been 100-103 degrees here the past couple of days and the '11 GT 5.0 auto running flawlessly in it. No issues at all.

guest01

Great time! Btw, now I understand better why the 2011 Mustang GT auto literally blew the doors off the 2010 Camaro SS auto at Ford's Media event (you may recall the well-publicized videos of the Mustang/Camaro drag race at the air strip). Not only does the Camaro SS auto have less horsepower (400) than the Mustang GT 5.0 automatic, the Mustang auto is **** quick ... and pretty consistently so!

todd03blown

awesome!! Wasn't your MPH like 115.8 actually?
