GT Redline

[foghat]

Yeah I definitely don't have that light grey section on my car. You sure that's not the Ecoboost tach?

You positive? My GT has the grey. I'm in Canada, maybe that makes a difference.

Here is mine. Just took these today. One with the lights on and one off. The grey area is there for sure. Yes, I had a GT

Redline is before fuel cutoff. Usually a couple hundred RPM.

In most cars you should shift as close to redline as possible for max performance. There are some exceptions, especially with some of the new turbo engines that fall off quite a bit at the top end. The EB is one where shifting a bit before redline can be faster. You basically want to shift such that you maximize the average HP when you drop the revs. This also means that if the RPMs drop a different amount for different shifts, you may want a different shift point for each gear. But for the GT, just shift at redline.

Oh, and to find redline, just hit the fuel cutoff a couple times, pay attention to where that happens, and from that point on just shift just before you hit the cutoff. You'll really get hosed on performance if you hit the fuel cutoff during an acceleration run.

Except you'll never make it to the indicated redline (7000) in the GT, due to the party abruptly stopping at 6800. Something is not right with the way things are setup.

Wow...calm down ladies, its the internet. you could continue your "sword" fight in PM right?

Won't blow up but the life span of that motor can be significantly shortened by high rpm use.

Ok, I'm legitimately confused here. I've seen that the Coyote engine redlines at 7,000 rpm. But my gauge cluster reads a 6,500 rpm redline, and pictures I've found online of other GT tachometers read the same:

So what's the deal?

Yeah I agree it's a little confusing. Ford put some extra margin on their redline, is how I interpret this. I usually reach for the shifter closer to 6,000 rpm, because I'd rather shift a little early than hit the limiter.

It's funny how people can find a way to fight about most anything.

Jimmytwotimes starting a thread about the redline?! Welcome to the dark side Jimbo! ;)

The redline is far earlier than 7000. Looks to be 6500 or so if you go by where it starts on the tach. Point being, on the GT, for max performance you should shift as close to the rev limiter as you are able, without hitting it. I've edited my post to be more clear on that.

If you increase the brightness of your gauges does that gray show up?

I think you are right. Car and Driver says 6500 too.

I just don't get the way they've marked the redline on this car. Off to the left, there is an actual line that is red that starts at 6500. There is also the grey at 6500. Then there is the the single hash at 6500 and then the bolded hash (or whatever) at 7000. Not sure what is trying to be conveyed. It is confusing.

Redline is not 6500. You can't define redline by what you see on the tachometer. 5 of my 6 vehicles didn't have a true "redline" indication on the tach. If I remember correctly, the 1 out of the six was my 91 cavalier...it didn't have a tach. The redline on an engine is defined as the critical point on the engine you don't want to go past. Again not going to blow up as the valve-train, specific to the new coyote, is well capable of 7k+ rpms. So redline, in this car is whatever the Manufacturer set it to, to indicate an "overrev" code in the PCM

And CO GT you can post up the numbers you received from whatever research you did, but I'm telling you what the car actually does...ya know in real life.

And please do site your souce and not just say "Ford" as that is incredibly vague. Most magazines seem to think the Redline and Revlimiter are both set at 7k

Also, just googled and found JPC did some data-logging and also found the rev limiter to be 6800.

Edit: also maybe there is a correction it might be 4 out of 6 since the darker hashes start at 7k on the mustang. Most sources seem to indicate the redline of the coyote is 7k. I would be inclined to think that is what Ford set it at.

So how does one know what this critical point you should not pass is if not for the markings on the tach? The actual line that is red (and most often used to indicate redline in cars) starts at 6500.

I am thoroughly confused at the way this tach is marked up.

A boss 302 makes peak horse power around 8k on the coyote engine. Ours is limited too 6500 for redline but let's us push too 7k but after 6500 HP goes down. Wonder if using a boss intake manifold and setting to 8k would be OK for these engines since its built a bit better than a regular boss 302 engine?
