Redlining your car

[Bikeman315]

P.S. Doesn't the auto shift at, or before redline no matter the mode it's it?

Not sure but at least you do not need to worry about it hitting the rev limiter.

No , in track mode the auto will let you stay in redline without shifting for you

I would not bounce of the limiter, but I see no issue getting to near the redline in spirited driving.

Past experience has shown for me that a few hundred rpm short shifting seemed to produce lower ET on a drag strip, unless you have an lightweight engine package and low geared car that zing's the rpm up instantly that's a different animal

big gray area.....redlining is pushing things to the limit and stock parts break
at any given moment when pushed to the limit ...No risk no reward but when
you spin a bearing or drop a valve its 99% of the time at the higher RPM and
not from normal driving

I've always understood hitting redline every so often is pretty much irrelevant. These motors are designed to rev unlike the LS counterparts, so unless you just sit banging off the limiter the engine isn't going to notice anything. I just make sure my coolant and oil is warmed up before I get anywhere near it.

Hitting the limiter isn't going to hurt anything as long as its not sitting there, you should be fine to hit it every once and a while.

Unless the power curve falls off a cliff once you hit peak HP rpm, average power to the tires ends up being higher when you use a few rpm above peak power rpm rather than rpms further down on the low side where less power is developed. This would be engine-specific and might depend on other details.

Right, the typical car has a redline 1000 or 1500 rpm above the power peak. But the Mustang GT only allows an extra 500 rpm.
The specific optimum shift point will vary based on the power curve, the gearing, etc.

I have calculated the optimum shift points for the 2015-2017 GT, and it is ~7300 rpm (varies with gear), and the stock redline for those cars is 7000 (or somewhat less). So short shifting is NOT optimum for them.

I haven't hit redline yet on the highway....it's pointless in 1-3rd as it's just wheel spin and in 4th, it is go straight to jail...do not collect $200.

Exactly.

The only time I can think of where short-shifting would make much sense involves upshifting before you enter a corner just to avoid having to upshift in it. But that's just a wee bit outside the way OP is looking to use his car.

Ford warranted the power train for 60,000 miles, with full ability to hit the refine. If you leave the Ford engineered nannies in place, I would expect you are operating the engine within its design specs and abilities. But anything you beat on will generally fail sooner than something lightly used.... my 2015 is full stock, I have probably done 100-150 1/4 mile runs at full throttle, nannies on, hitting redline at each gear shift. No issues, nothing is broken, doesn’t use any oil....runs smooth, straight and quiet down the road....

I have a new 2019 GT. Need for green with the black racing stripe. Damn do I love this car.
Prior to this one, I had a 98 with the 4.6L engine. It was quick and sounded good but NOTHING like this one.

The problem that I've had is how quick it gets to 7,000 RPM in first. I've bounced it off of the rev limiter a couple of times now and panicked about it. It will take me a bit to get used to it for sure. A few early mornings on the local highway should help.

Is there a way to set the rev limiter lower than the factory setting? I know that is the opposite of what most ask, I just don't like getting that high into the RPMS if I can help it.

And as for the rev matching... Arrgghhhh.. I hate that.

 

[Norm Peterson]

Maybe start getting used to this car by NOT doing any hard pulls in 1st just yet. Use 1st just to get the car rolling, maybe only to 3500 rpm, and wait until you're in 2nd to lay into it.

You can set the shift notification to any RPM you like...it won't stop you from revving higher but it light up the dash and turn red once you hit that set RPM....that could help you get used to it. I'm guessing you have the 6 speed manual?
