Reving to high RPM bad for the engine?

[mc68386]

-As stated in many forums the 5.0 engine doesnt feel quick in low rpm range but really accelerates rapidly after 3500 rpm.
-Just to achieve fast acceleration is it bad for the engine to shift at high rpms.
-I have been shifting gears below 3k rpms but acceleration doesn't feel as quick but I don't want to stress and wear my engine parts early by rapid acceleration.
-What is a happy medium and at what rpms you all change gears usually?

As long as you let it warm up first, your engine will love running at 3k to 6k. The interior will rattle to pieces long before the engine wears out.
But driving high RPMs will kill your MPG. Do you mind paying for 2x more gas? No? Go for it!

This whole thread reminds of the Foreigner - Rev It On The Redline song

And if one single person asks, who's Foreigner, is that some kind of ancient band, I will personally come over to your house and beat you about the head.

Yes I am old, lol.

Huh, I normally shift around 2500 or so in town. I see no reason to run an engine at low load, high RPM.

My car has this thing on the dash that shows the RPMs. It's white in one area, which I assume is the safe running area, and red in another, which I assume is the danger area. It's almost like Ford wanted us to know where the safe operating range is.

But shifting at 3,000 rpm isn't doing you any good either. Enjoy the sweet spot between 4,500 and 7,000 rpm frequently, keep up on your maintenance, and you won't have any issues.

I shift when the little green light tell me to it's way bellow 2000 rpm actually. I suppose Ford know there engines and for 30000 miles on my 5 years old Fiesta the only thing I changed shifting on the green light was a radiator fan as it goes busted in a 40 degrees celsius heat when my car stop on the interstate because of traffic jam courtesy of our road workers :(

I shift at 2500-3000 for daily driving. (3.73 gears)

i'll probably shift around 4-5k for some fun every now and then, and 6-7k when i really want to gun it but i rarely do that.

Your GT Performance Pack Mustang has a green shift light? And it lights up below 2000 RPM? I thought that was idle speed. ;)

My GT Manual (Analog gauges) does not have a shift light at all. If it did I'd find a way to black it out.

Mine is 2017 and is right there in the right corner of my middle gauge don't know if this is available on 2018 and up Mustangs. Or if it's just an EU mustang thing but yeah I have a green arrow pointing up for shifting 1 gear up. Most annoying is when at 80 km/h it ask me to shift to 6th gear (you can calculate how much RPM is this my rear is 3.55) way bellow the 2000 RPM mark. All other times I use it.

My 2019, the gauge cluster lights up red when you hit the limit lol.

You actually shift well below 2000RPMs???

Why would you pay any attention to it?

Here's the deal: Yes, wear and tear is accelerated on any engine at high rpms. Additional heat, more rotations per second, etc. However, consider that, even when you accelerate fast, you're only in the top 90% of the operating band for an order of a few seconds, depending on how fast you get up to. Accelerating quickly at WOT to 60 mph, your car is only above 7,000 rpm for a second or two at the most (if you have an '18 since the redline is 7,500 rpm). That said, I rarely take my car above 6k rpms because I don't really need to, although when I do wind it out, it is glorious because the sound is amazing (and the pull is awesome at high rpms in the Gen 3 Coyote). Revving to even only 5,000 rpm still makes the car much faster than nearly everything else on the road, and you get to feel the peak torque in any given gear (4,600 rpm, I believe). But, when I do rev it to redline, I don't worry about it. The engine doesn't live there - it's only a fleeting moment and then it's done.

I would argue that shifting under 2,000 consistently is worse for the engine than shifting at 3,500-4000 regularly, and taching it out to 7,000 + from time to time. Carbon build-up, piston slap, and load at lower RPM is not the Coyote's favorite snack.

I feel bad for all these coyotes that are being deprived there God given right to howl. The beast wants to scream. Let it...

Same man! I think the car is very responsive in that rpm range

 

[2019fordmustang]

The automatic transmission shifts at pretty low rpms tells me shifting early is not a bad thing. With manuals it's tiring to shift that quick. I guess my next mustang will be automatic. I love the manual but feel like I'm getting lazy now.
