Doesn't feel like 460hp...?

[Smokey613]

You got me by 25hp but this is my experience as well in my 16' manual. Only time I could get them to spin on takeoff was if the road was damp. When I put on my 275/305s it feels like a weighed down boat off the line. Not impressed at all.

This is my experience with my 2015 vert auto with Conti 265-35-20 tires. Even with the Advance Trac off it just hooks and goes which is actually what we should want, but every once in awhile a little tire spin would be fun.

Peak horsepower is a static figure and is the max capability of the motor... while torque is the force applied.

Maybe it’s just the Variable valve timing doing it’s thing

I don't think so. Only because in higher gears the torque is instant and doesn't lag like in lower gears at the same rpm, at least in the A10. And occasionally I can trick it in a lower gear and torque will be instant. I trick it by getting on it momentarily then letting off. Then getting on it again. Sometimes that defeats the lag and full torque is instant and the initial jump is noticeable stronger, even in lower gears.

I think the lag is due mostly to traction control software, and Ford may also add the lag partly to reduce drivetrain stress. The drivetrain stress part is just a theory.

So the torque output isn't based on the rpm? Same rpm but different gears get you different or in your case more torque in a taller gear?
Nannys disconnected too?
Tune? What's the stall speed factory?

I have never disconnected that connection by the airbox. What would that do for a daily with a manual? I don't want any management of anything. I'll manage it.

Totally stock car, stock tune, never been modified (bought it new off the lot in Nov. '18). 2018 GT Premium/A10/PP1/Magneride/Safe and Smart package. It's hard to explain. My theory is that in lower gears, the car knows it's more likely to spin the tires upon a quick throttle input, so it modulates the throttle output upon a quick throttle mash. For example, with my A10 PP1 in 3rd gear at 4,500 rpm (essentially peak torque rpm)...mash it...car begins to accelerate, but at a rate that feels more like half throttle, for probably about 0.2 seconds. After 0.2 seconds (give or take), full torque output is allowed and it smashes you back into the seat. Similar effect happens at other rpms in the same gear, and in 2nd and 4th gears. In a higher gear, say 5th gear, at 4,500 rpm, mash the throttle, and the car accelerates without the 0.2 second delay in full output. Because the computer knows the car is not likely to spin the tires at 4,500 rpm in 5th gear (that's somewhere around 70 mph, give or take), so it doesn't nanny it or limit torque output.

3rd gear acceleration, after the 0.2 seconds, is definitely harder than 5th gear acceleration. But in 5th gear, the full throttle output is not delayed like in lower gears.

Sometimes I can trick it, for example. Same scenario as above in 3rd gear at 4,500 rpm, mash it, nanny kicks in for 0.2 seconds. Let off, then go back to 4,500 rpm and mash it again, and WAM, full throttle is instant, slammed hard into the seat. I'm guessing the computer remembers that you just tried it and the tires didn't spin, so it doesn't limit the torque as much on the 2nd attempt.

The 0.2 second full output delay occurs even with the traction control switched off. I also have a theory that it is there to help protect the drivetrain.

How so? The throttle mapping makes a big difference. If I give it 1/4 throttle in Normal or Wet mode its not 1/4 throttle.

In Sport and Track mode the throttle is mapped much more linearly meaning that 1/4 throttle is 1/4 throttle making the responsiveness feel better and making it feel faster given the same pedal input.

If I want 1/4 throttle, I steep on the throttle 1/4 the way down. Having a computer turn my 1/4 input into a 1/2 input does not make anything better. It hurts me on track, where linear power delivery is important as I roll on the throttle out of a corner, or use maintenance throttle mid corner. And 100% is 100% even if the electronics give you 100% at 50% throttle. All it can do is fool you into thinking you have more power because of exaggerated part throttle response, which makes the car harder to drive smoothly.

Now sport mode shift logic is a help with an automatic, if the car is reluctant to shift down even with big throttle inputs (the root cause), and you don't use the paddles to shift it down manually (or it is slow to respond to them). My solution, get a manual and the driver dynamicly determines the shift logic (and amount of throttle) .

Isn't that what I said? Throttle response in normal mode is NOT linear.

Sport mode and Track mode are linear throttle mappings.

I think you misunderstood me.

My 255 P Zero's were pretty decent. 1.87 60' bone stock.

Ever wondered how accurate the track apps are
Also the car runs 12.5 rather consistently on 402m on the street.




Best 1320@on the highway

It is definitely a different feel for us coming from driving late model Hemi cars and trucks. The Hemi has a lot of low end torque and really sets you back in your seat like our old muscle cars we grew up driving. I have had to re-learn that this engine likes operating north of 4K rpm. The good thing is I don’t find myself breaking the tires loose as much as I did in my tuned 2011 300C, especially with the “no nanny” tune I had for it. Unless I put it in track mode, this Mustang just hooks up and goes. I will say, I enjoy driving it more than ANY vehicle I have ever owned and that is saying a lot for me. Besides, drop the top and it is really fun!

Some of my past rides:

1965 Olds 442
1967 Camaro RS convertible
1969 Olds 442 W-32
1969 SS396 Chevelle
1974 Z28 Camaro

Good wheel choice - those look good on that color.

 

[SpeedRacerXT]

lol, probably just the wheels...more aggressive looking wheels make the car feel more aggressive.

I have a 2019 Bullitt and it is still under 1000 miles. My biggest problem is keeping the "leash" on it. It just wants to go and I'm trying to break her in per manufacture instructions. Based on my limited driving her I don't question the HP rating on this car as the few times I have passed cars on back roads I can't believe how quickly she accelerates. My last ride was with a friend who drives a Corvette Z06 and he was amazed how quick she is. I love this car!!!

I feel the same delay (even posted about it a few weeks ago) from the traction management with the A10. It's as if it needs a couple of tenths of a second to determine the traction, then react with full throttle after deciding there's enough traction. It certainly makes the hit less impressive in lower gears. Wish it was much quicker reacting. Actually, I wish it was reverse of that: allow full power, then back off if the tires start to break loose.

And you have an A10 and still get this effect. Well we have a traction control option already so don't need that. Ford clearly has employed some algorithm to reduce the torque hit in the lower gears even when advance trac is off. I'm sure that was a smart decision at the corporate level to reduce accidents. I'd just like my car a little more responsive, it's already plenty fast.

I have never disconnected that connection by the airbox. What would that do for a daily with a manual? I don't want any management of anything. I'll manage it.

I have a manual. Far as I can tell disconnecting the plug makes the car drive like AdvanceTrac off.

The plug seems to disable ESC and TC completely, or no nannies. Still get the softness at low speed full throttle. ABS still worked. Though you get two lights on the dash permanently if you pull the plug. The ESC disabled light and also a warning light.

After a few days I plugged it back in. I can always easily shut off the ESC and TC with the button if I want to since that feels the same and I'd like keep ESC on for rain.
