Redlining your car

[GTP]

The rev limiter is more like a warning, "You forgot to shift, dummy!"

I have bounced off the rev limiter at the track in both my 2016 A6 and 2019 A10 GT's. Its purpose is to prevent the engine from revving into the range where damage can occur. (Valves can reciprocate only so fast.)

It's no big deal,

...
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

Couldn't find a thread about this sorry, maybe I'm not putting in the correct key words... Speaking of reving, my 2019 GT A10 wont rev past 4500 in park or neutral. I thought I had a voltage gauge problem so was bringing the revs up slowly to see if the gauge would go up and noticed I cant rev past 4500rpm..Does it have a rev limiter in park or neutral?

Yes - that’s normal. Park/neutral has a limiter so you don’t sit there and bang off the limiter when you aren’t in gear.

Thanks...

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.

Not sure if the 18+ are running different tires, but if not and you are on stock Pirelli's, don't play around until they are warm, they break loose quite easily and a bit unpredictably (well for me) when cold.

If you pay a tuner, they can lower the rpm cutoff, but like others said, it is far from "gentle".

I never beat my manual cars with launches. I don't lay on the throttle until the clutch is fully depressed, don't ever 'power-shift' (leaving throttle pinned while shifting), and don't bang shifts either. The D4 tranny doesn't like it anyway, so no need to risk grinding gears, or getting locked out, and slow down more than if done more sedately. To me, a manual is to enjoy the driving experience without stress, meaning I still drive aggressively, but not overly so, therefore not abusing it. When abused, that's when things can go south quickly, like a money shift, or damaging the tranny. When I'm past break-in, I don't plan to get past 7K. No need for absolute maximum acceleration for me. With the redline at 7,400 and rev limit at 7,500, it's super easy to hit it, which would slow you down, defeating the purpose of revving the engine higher . The car is plenty fast without abusing it, so not an issue to me at all, but to each his own, of course .

I think I've only hit 6k rpm in second gear. I haven't found a safe enough road to get anywhere near redline in 3rd on up. 4th is pretty brutal at 5.5k rpm on a street with other cars in the area. One day I will find a safe enough area to let it loose

Hey, you can't redline 4th, even if you want to. Ha ha. You knew that, right? Even with our 3.73 Torsen, you hit the speed governor at 163 before being able to hit redline in 4th. So you can only redline 1st, 2nd, and 3rd .

 

[m3incorp]

Yep, I knew that . Now that you mentioned it, I may have to ask Roush if they remove the speed limiter in their tunes....most of the European tuners remove the limiters when they do tunes.....food for thought.

This car is a high revving engine! I drive mine hard. It’s a 5.0 with a performance package.

I bought a complete 2019 5.0 out of a totaled GT. The engine did not have scratch on it. I can tell you w/o hesitation, these are some really strong, well designed engines. The bottom end is massive and extremely well supported featuring 4 bolt mains with cross main supports.

The valve train is very lite weight for a mass produced engine. I mic'ed the bores (engine has 11K miles), stock is 3.662" and most mic'ed dead on, with one being -.0001" under, and three were +.0002" over (that's ten thousands). On a production engine this is amazing.

Oil squirt nozzles direct oil under the pistol skirts to heat the oil quickly and provide additional cooling when up to temp. Piston pins are fully floating. Piston skirts have an anti-wear coating applied to the skirts. Rings are very narrow to reduce friction.

I am very impressed overall, which means I would not hesitate to zing these things to redline on a regular basis. They are built to take it.

What did you put the engine in? I thought your 2018 would have the same engine.

Yep, I knew that

On the track, sure. But on the street there really isn't any need to, so you might as well save even the chance of valve springs gradually getting a bit tired for your track time.

Someone just did the ultimate torture test on a 5.0 by running it across country in a record 25 hours and 55 minutes. That's almost 26 straight hours of an average speed that was almost 120 miles per hour. He said he spent something between 3 and 4 hours sitting on the speed limiter of 155, lol. If that doesn't prove these cars can take some abuse, nothing will.

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....

If I may ask, what is your milage? Estimate is okay.
