Is revving the car to max in neutral okay as it has a limiter?

Was just wanting to make sure revving the car to max for a second in neutral is fine for the engine. I know it has a rev limiter so I figured it is a-ok, but just wanted to double check as everyone that comes up wants me to pop the hood and let them hear how crazy sick the motor sounds.

This is on a GT-500, thanks in advance.

idk but I wouldn't...a blip to 4-5K is what I would do. I've heard it was bad (something about floating?) but don't know.

What's the point of doing this in the first place? And no, I would not do it either. Do it enough and there is a risk of floating valves and stretching rods, IMO.

Seems like a dumb thing to do just because people are asking for you to do it.tell them to rev there own car at max rev.if I did burn outs every time someone ask I would be buying tires every week.I don't do it!!

Lol alright, I've only done it a few times, I can't see why it would hurt the motor as the limiter is there, but good to know. Even talked to a Ford service guy and he was like it shouldn't do any harm. Btw you have to rev past 4-5k to actually get the S\C going which is the thing everyone wants to hear :P

I could see floating if you were to HOLD it on the rev limiter, that would make sense, but you'd have to be stupid to do that. Regardless I think I'll set the RPM max indicator lamp and turn on the tone to max 5500RPM to avoid hitting the limiter ever. Anybody recall how to do that? I haven't set mine up yet.

So why did you ask for peoples opinions again?

I'd ask your Ford service guy if this would be benificial for your engine. Then ask him to rev his cars engine in neutral till it bounces off the limiter.

I wouldn't do it to any of my engines and I've walked away from purchases because the seller has done that in front of me.

Just drive the thing!

Because I was curious but the floating bit confused me, I mean the limiter is there to prevent damage, right?

Anyway does anybody recall how to set the max RPM indicator lamp\sound warning? Shifting in the GT-500 RPMS come up so fast I'd like to get a quicker warning with an audible sound which I know all Mustangs have an option for...at least I think.

Strangely enough, setting the shift light is covered in the owner's manual (what a surprise). In the Settings menu, select Vehicle then Shiftpoint then you can set the light on/off, the tone on/off and the RPM to activate.

When it's a Shelby it's the super-charger everyone wants to hear, exhaust is exhaust, and mine does have the SVT tuned exhaust. My prior ride was an SRT-8 6.1l Challenger w\ Super 10 mufflers + 1 inch turn downs prior to them.

Loud as hell, always drew attention due to the exhaust sound, but with the GT-500, it's the first car I'm not sure about putting a louder exhaust (prob boss 302 style sides) on it, as the super-charger whine is so addicting and awesome.

My father has a CTS-V and his super-charger is DEAD quiet, even though it's making 560HP\560TQ. I personally LOVE the whine and to me that is what really turns heads.

If I DID do one it would have to be the Boss 302 style quad exits with the plates that can change the sound.

There's a different between reving an engine through its power band (say up to 4500 rpm) and putting your foot in it waiting for the rev limiter to kick in....that show you can kill an engine because of the no-load condition and 2ndly.......you're relying on a piece of IT equipment to keep you from damaging your engine........not smart....unless you don't care about your car.

Revving the engine to redline in neutral isn't going to hurt anything. The rev limiter/fuel cutoff will happen long before any damage is done to the engine. It's set there from the factory for a reason. There is virtually no load on the engine when revving in neutral and there is more potential for engine damage from over revving in gear while under acceleration (max load) than in neutral. You will not float the valves and you will not "stretch the rods" as long as the factory rev limit hasn't been changed.

That being said, I completely agree with the others about having no real reason to rev it that high in neutral.
