Finally broken in. Red line question

[boB]

After a 500 or so mile break-in I usually redline my "fun" cars ( and motorcycles) at least a few times a day. Even my Honda CRV gets redlined occasionally. I figure the designers set the redline at a point that prevents engine damage, none of my cars seem to have suffered from this treatment.

Well, I like hearing that the cars from Ford you beat up keep coming back for more. It's just that harsh treatment doesn't generally breed longevity in machines. No speculation, plain old fact.

My 2019 fastback GT Premium on order is my first Ford, so I'm glad they will handle some abuse. I can say this with complete confidence, demanding 100% performance from an engine will wear it out a lot sooner than not doing so. Basic machine fact. But, if the time to wearout is acceptable to you, why then go for it whenever you can without getting a ticket. No complaint here.

Cheers.

The occasional redline is nothing for wear compared to racing an engine. I don't understand buying a car like this with no intent to ever drive it to its limits. The Coyote has a reputation for very high durability and longevity and was purposely overbuilt as an NA engine.

Isn't a redline here and there actually good for your engine? Maybe I'm thinking the PI/DI setup or only DI engines. Not sure it applies for a purely port injected engine.

I think the key word here is 'occasional'. Some people are at least suggesting much more frequent than that.

At the dragstrip, during a HPDE session, or possibly at autocross (far less likely), sure. Close enough without actually hitting the rev limit, anyway. On the street . . . I can't see there being any mechanical benefit in running all the way into the rev limit that's not available by the time you get to 80% - 90% of redline revs. Any psychological benefit that may result is a totally separate matter that the car will not benefit from.

Personally, even with an engine having a reputation for excellent durability, I'd rather burn through its fatigue life out on the track than throw it away on the street.

There is a history of Coyote engines becoming oil-burners if they're not driven hard here and there during break-in. Strong pulls to the red-line, and then backing off and cruising, help bed-in rings, bearings, mating surfaces, etc. A little heat and pressure, and then back off.

Really, I think keeping the oil clean and fresh is much more important than how many times you red-line the car.

Actually, even more important is not taking it to high rpm (north of say 4500) before the oil is fully up to temp and can flow easily. High revs soon after cold start is the way to prematurely kill an engine.

Oh, yeah, definitely. I watch my oil temps like a hawk now. I never realized how long it takes to get the oil up to temperature.

Why the hell would you buy one of these cars and not have fun with it?

Twist it every now and then. It's good for the soul.

Mine is an auto but ive hit the limiter using paddle mode probably 10 times between 1k miles and 5k miles already.

When not using the paddle shifters, i get the red dash light and full revs probably once or twice a week.

I think the danger comes in when you get up to the top RPM range (say anything over 6500) and HOLD it there for an extended period of time, especially if you aren't moving fast and don't have adequate cooling. Or if you do it several times in rapid sucession without any real time in between. Those are the things i would recommend avoiding.

I haven't tried lately (not something i do on purpose if i have the presence of mind) but i am pretty sure when i have gotten the "lets hear that exhaust" cat call after a cold start and i tried to rev it while parked the saftey featuress kill the throttle around 5000 rpms and won't let you do it even if you wanted to so you should be pretty safe. I don't know if the feature is tied to having the car in park or the oil temp...like i said actually testing this is not something i do on purpose if i am actually paying attention and i usually make it a habit to use my auto start function and give it 2 or 3 minutes at idle and then and then there is 3 or 4 minutes of driving through the neighborhood at 2000rpms or less before i even hit the streets. Even then i usually don't go full throttle as a matter of habit, though i have been known to do it late at night when no traffic was around a few times.

Can anyone confirm the feature i am referring to and shed some light on whether it is just in park/neutral or if ford tied it to the oil temps in the 18s? IE, it isn't just the normal redline but a variable one depending on temps?

The only reason i am aware of this is that my C7 had a dynamic redline which rose from 4500rpms to the normal top level based on oil temps. It was a nice feature, I liked it.

Not sure if the gen 3s do this but i think they might be doing it on the back end a bit. (even when it is not immediately obvious to the driver). I am just guessing though i really don't know.

It does the same thing if I rev it in gear w/ the clutch in in my '15 manual.

Does it do any kind of on the fly dynamic redline adjustment when actually driving?

I edited my post above to explain, my C7 had this feature of a dynamic redline based on oil temps which was pretty darn cool.

The dynamic redline along with the ability to press and hold the left paddle for the lowest gear all at once are two things i wish every mustang had.

It will prevent you from using launch control until coolant/oil is up to temp.
