Not enough power?

[MSMStannyl]

Turn stability control off and you should be able to chirp 1 through 4th and get a little fish tail on each gear shift. I keep mine on just so it does not fish tail when I shift hard, don't want to hit the curb plus from what I researched it does not improve your times.

Isn't there also torque management at work, specifically for the lower gears? From what I understand, you would need a tune to get rid of that, or at least to have it turned down. At that point things really open up quick.

That's probably the norm. The S550 is kinda of a porky car. Aren't the '11-'14 a little lighter? That would account for the outcome!

I believe you're right but they also have a little less power (assuming stock vs. stock).

Just want to start by saying, I have not dyno'd my Mustang yet. I intend to as soon as I can.

When that happens, I of course will get a better idea of how much power mine is putting down.

As of now I'm going off my butt dyno, and honestly I was expecting more. I have 500 miles on it so far, and it really isn't as fast / powerful as I thought / hoped it would be.

Example: I tried launch control yesterday for the first time. I launched at 3k in track mode / traction control off, and it barely broke loose. A couple chirps from limited wheel hop / and almost no chirp into 2nd gear.

I'm not trying to burn my tires up (tires are expensive). And I know traction=good times at the track / more money in your pocket. I just thought I would have to take it easy in order to preserve my rubber. But i'm finding it is actually the opposite. I'm having to try really hard to feel wheel spin / break traction.

I have heard / read many people saying they are having trouble preserving their tires or maintaining traction at the track with the stock tires.

Kinda starting to wonder if there is something wrong with my car....

I'm not the best driver out there, but I'm no amateur.

Any thoughts or guidance is much appreciated.

s550/Gt/PP/PP 400a/all stock.

have you tried track mode + advancetrac off?

plus, only 500 miles.

TQ management only caused issues with launch control when I was stock. If you launch off idle or at 1k rpm it should not slow you down, I did not feel it unless I used launch control. The tune does indeed get rid of it and lets you launch hard without kicking in once you spin too much and catch traction.

I think you are basically experiencing a refined, heavier mustang that actually hooks up well opposed to a lighter, less refined (insulated) mustang that doesn't hook quite as well.

I experience the same thing when I get into my Fiesta ST, I'm like man this thing rips! It spins the tire (only one tire mind you) in 1st and also in 2nd unless the road is freshly paved and completely straight... then... the fact that the body of the car is so small and light, the suspension is much more firm than the PP GT... the steering is sharper... all these things make for a driving experience that is far less refined but makes you feel like you are going fast.

The mustang is fairly soft, insulated, has sticky summer tires and a high revving v8 that doesn't give you 100% of power all in one surge at 2500 rpms.... its a progressive swell of power throughout the rev range.

So... once I jump back into the GT.... I'm like wow this car is huge, nice and quiet with lots of power... but it doesn't rip the steering wheel out of your hands and you sure don't have to fight to keep it in your lane.

It feels like true sports car(GT car) instead of a muscle car in my opinion...

Its a fast car but it doesn't feel like a high 12 second car because of the size, insulation and power band.

My GTPP felt like a switch was flipped around 900 miles and both the engine and tranission were night and day different in terms of power and smooth shifting. That being said my coworker has an 04 mach 1 and even during my "slow" period it still trounced his. And that car is fast! The design of this car overall takes away a lot of the feeling of fast acceleration and replaces it with tremendous ability to control.

my car is stock and ive been able to easily break the tires loose in 1st, 2nd and even chirped 3rd gear, with all the nannies on.

Pp car? Summer tires?

OP: I had a similar impression after my first test drive of the S550 coming from a 2012 GT. I felt like my '12 was quicker, though the difference was small and I couldn't be sure as I never dyno'd either car.

It is true that if you search for dyno results on an 11-14 and compare to dyno results on the S550, they seem to be putting about the same hp range to the rear tires. Not something you'd expect considering the published differences in output. Actually had a post on this you can read if you search a few months back. However, considering the extra 200pds or so the S550 carries, it would make sense that it's slightly slower if the real, RWHP is about the same.

A few things to consider:
1. The 11-12 coyote was probably making a bit more than the 412hp. There's actually an article on this with testing by one of the major car mags.
2. IRS = more line loss, more moving parts between the motor and rear wheels.
3. The car will pep up a bit over time. I've got a tick over 2k miles now and it feels noticeably quicker than new.
4. It is still bloody fast. After the first 1k, I've not had an issue spinning the tires between any gears in sport mode. I try not to do this to preserve the tires, but sometimes it can't be helped!
5. An 11-14 Coyote might just edge you out in a drag race, but throw in any curves and the S550 will win with the IRS.

yes PP car, but i'm on yokohama advan sport a/s tires. it was a few weeks ago, probably about 70 degrees around 8:30 AM. i was pulling out of a gas station on a service road, and like every other time i pull out of that gas station, i go WOT.

the chirp in 3rd that day was quite surprising, since it was the first time it ever happened. it felt like i hit my shifts perfectly. it might be when i hit .84g on my accel.

Launching is pretty tricky for me... but I have the 3.31 gears. With your 3.73s, it should be easier. Note, though, that Launch Control does use traction control, and TC will pull power and bog you down if detects too much wheel spin.

 

[Raider]

Thanks for all the input guys.

I just drove my buddies 08 gt-500, and he drove my s550.

I felt the power / feel between the two cars is comparable. Which makes me feel a little better.

He said he thought my car was strong.

I did feel a noticeable difference between his 3:55 gears and my 3:73.

Good to hear guys are feeling a slight difference in power once they get over 500 miles.
I'm looking forward to it.

You mentioned you were disappointed that it could barely chirp the tires. You are using launch control. Launch control is DESIGNED to get you moving with the least amount of lost traction possible. If you want to light up your tires and see your car is a lot more powerful than you thought, turn of ALL the nannies and just do a classic high rpm clutch drop. I'm pretty sure you'll realize your car has plenty of balls. If that doesn't work, then yeah, there's something wrong.

I believe you're right but they also have a little less power (assuming stock vs. stock).

You did not walk a new GT with your 2012 unless the guy didnt know how to drive. How do I know this? I had a 2011 GT TP and now have a 2015 GT PP. The new car is faster...sorry.

 

[Raider]

Bare with me, but I keep reading/hearing the word "nannies" What does that mean?

And just a sanity check, but to do that, I would put it in track mode, and then hold the traction control button for 10 secs and then advance trac is off right...?

Is there anything I'm missing?
