What's the 5.0's redline?

[jon2002]

Hello all,

What is the actual redline for the 5.0 motor? The tach on my 2016 GT PP is mighty confusing...it appears to be either 6500, or 7000.

The dash goes all red at 6500, but it seems to still pull hard to 7000.

Also, what's the fuel cut off rpm?

Thanks!

I thought Coyote redlines were at 6800 rpm's with fuel shutoff just past 7000 rpm's, but with hash marks on the tachometer starting at 6500 rpm's. I could be wrong as I had my Coyote tuned long ago and have shift points well past 7000 rpm's now, so I've forgotten what it was like when stock.

Owners Manual should answer all of your questions, that is why Ford supplies one with every car they build, very easy reading and very informative!

I believe those initial hash marks are the "caution" ones with the engine redlining at 7K. However, I have experienced fuel shut off at 6800 rpm.

Hi there

I did much research on this, I think peak power is 6500rpm, with limiter/fuel shut off being 6800-7000rpm.

Most tunes seem to increase the limiter to 7400rpm which I'd be a little wary over if your still running the stock oil pump.

Thanks to everyone who has responded.

Why did Ford feel the need to make a simple tachometer redline tremendously confusing?

At what rpm do the automatic GT's shift when floored?

I think the redline is about 6500. The automatic should shift at at that too.

Redline
shift point
rev limiter
peak power

not all the same thing....

the "redline" is simply a number on the tachometer. this does not indicate peak power, optimum shift point, peak power, or the rev limiter location

the shift point is generally best located slightly past peak power to maximize the "area under the curve" and will allow the next gear to fall into a higher RPM range and will increase average power rather than just touching a peak in each gear.

the rev limit is just a point past which the engine may experience issues from too many RPMs like valve float, spring breakage issues, etc depending on the type of engine.

the rev limiter can be raised, the shift points altered, etc to suit the engine combination/modifications.

redline is 6750RPM
fuel cutoff is 7000RPM

True, they are all completely different. But, the redline is the maximum safe operational engine rpm, as determined by FoMoCo. For Ford to make it unclear on the tach is ridiculous. I have no interest banging the rev limiter on my 5.0.

In my teenage years, i've blown the headgasket on a Honda CRX Si from banging the rev limiter one too many times.

Thanks everyone

I asked the same question a while back.

To bump this with a few questions...

1) without a tune, where is the fuel cutoff? I see people say 6,750 and 6,800 and 7,000 and 7K+ etc.

2) what is a "safe" redline? I see people saying with a tune they are shifting at 7,200-7,500 RPM which seems awfully high.

See the attached tables from the stock 2015 coyote:
The tables on the left are spark cut tables, and kick in first. As you can see stock is 6,850 rpm at normal operating temps. Basically the ECM will pull timing to less than zero (-2 degrees in my logs).

The fuel cut is 7,000 rpm, I've never hit it.

Most people seem to agree the stock motor is good to 7,500 rpm. I've got my fuel cut at 7,500 rpm and the spark cut at 7,300 rpm.

Thanks Plimmer! Could you explain why fuel and spark don't cut out together? I'm not knowledgeable about motors, was curious why you would still want fuel after stopping spark.

 

[Plimmer]

I'm not really sure why they don't cut together, maybe cutting spark gives you a "soft" cut and the fuel gives the "hard" cut. Not sure though, just guessing here
