Dumb question about engine revving at idle

Rev it up, won't hurt the engine As long as the oil is somewhat warm. No load, no nothing, Engine doesn't care. Don't sit there & bounce it off the rev limiter like some silly guys do... A dyno pull to redline puts a lot more stress on the engine.
I believe most autos will not let the engine rev past a certain number to protect the trans. I'm not sure if it's the torque converter or what, but I believe this is pretty common.

I wish you could get an a real answer rather than the peanut gallery giving you useless and uncalled for remarks. That's the CF...
When I get mine, you bet I will rev it up for the crowd when asked.
I would like to know the answer to your question.

Glad I'm not the only one. This forum has been very helpful for some stuff and very disappointing for others. Seemed like a simple enough question. I could see if I "asked" for everyone's opinion on IF I should rev my engine at a car show. Whatdya do?

I don't know for sure, but my Porsche does the same thing in Park. I am guessing the ECU won't let it rev too high to protect the engine. Was the engine warmed up at the time?

Yeah, engine was plenty warm and I was in park. I'm sure it's just a tuning deal from GM to help protect against abuse? Oh well. Thanks though.

There is some condition that limits the RPM. If he goose it right it may rev up more than 4K, but in most cases it will not let you. In any case it's enough that it sounds good and you really don't need to rev it high unloaded. A bit of a throttle bark sounds cool, revving it up high in neutral does not.

Rev it high enough and it is.
Tell an old neighbor who love to rev his engine. It coughed and stalled and next thing the wreaker was there to get it. The car never returned.
Revving an engine is needless and serves no purpose.
I always heard it was bad to rev a engine. It has no load.
I hear someone revving the engine I think idiot right away.
But I guess different strokes for different .......

Completely funny to see all these boomers going full on negative nancy “back in my day i heard” when the man asked a simple question. No wonder my generation steps all over the older guys. Instead of guiding us you sit a degrade. Bunch of “chads” and “would you get a load of this” vibes in here

All the new cars I drive that are autos have limiters between 3k and 4k when not in gear. My first car that had this drove me nuts because I thought it had a problem. I had to dig deep into the shop manual to find the deal. My M7 Z06 revs way up...so it is obviously a manual/auto thing.
Revving occasionally is not going to significantly hurt your car. The only thing that could is if you over-rev past the red line...but that is not possible in this day of electronic limiters, unless you downshift too far in a manual car. It's virtually impossible in an auto. If you have a pre-limiter car, you can completely destroy an engine by revving over redline in a performance car. Most EcoCrap cars can never even reach redline.
For those in the "it's bad" camp, you are correct that your engine will last longer if you never push it at all. A couple hundred revs in the life of a car is truly insignificant in the big picture, though. You're taking off, what?...a couple hundred miles of engine life? Who lets there Vette go that far into an engine's life anyway?

When I was a younger airline pilot fresh out of the military, I called a Captain friend that I both liked and respected to complain about a couple of asshat Captains I had recently flown with. After patiently listening to my grievances, my Captain friend responded, “Where do you think those asshat Captains come from?” When I had no answer to his question, he clarified his point by saying, “The asshat co-pilots I’m flying with today are the asshat Captains of tomorrow. Asshats don’t change as they get older, they just get worse. Fortunately, in the piloting profession they have always been relatively small in number.”
So, if anyone thinks that their own generation of enthusiasts are “special”, maybe they should stop and consider the shortcomings and naïveté of their own individual perspectives, less they risk becoming the asshats of tomorrow.

The rev match feature on the manual basically does exactly what most of the guys on this thread are saying is horrible to do. . . . .it revs the engine under NO LOAD in between shifts just for the sake of matching the shift.
It will easily hit 4k depending what conditions you are downshifting in.
How is that any different?

he was focusing on upgrading the cooling system in his car even though it doesn't overheat on the street anyway. . . . . . .just to have extra capacity that won't be used, but he'll know it's there!!!!!!!!!
