I have put in N while coasting in my buddy's long driveway to rev the engine to announce my presence. It sounds better than the horn but the engine response is insanely slow it will hardly rev at all even when you command full throttle. It's really disappointing.

I only do this when I have a tesla behind me. Race exhaust, neutral bomb. Gets their girl a little moist. Something a tesla will never do.
Do they like girls, or want to be them?

I've never been into transmissions but I'd heard that atf wouldn't be running through the transmission in neutral like it does in drive and would kill a transmission. That was about TH350s and TH400s, though.
AFAIK Autos pump fluid at all times when running. It's towing with the engine off that can cause problems on some.

I can only assume this is done for some fuel efficiency or emissions compliance reasons. Manual rev freely in neutral while almost all autos rev slow and only about half way to redline in neutral.
you should just buy a manual next time :-)

I'm guessing this rev bombing is youthful exuberance?
One of my pet hates with modern bikers is rev bombing instead of using the horn.
Sure, it's much safer to pull in the clutch, rev the nuts off the bike, and hoping you don't have to brake and swerve suddenly, than press a horn button.

Thats funny back in the day I was in my 67 Ranchero that had dual fours sticking thru the hood. I'm sitting at a light and two young kids pulled up beside on sum japanese bike He started revving his bike to real high rpm trying to impress me. Then just as I was looking at him in the eyes. Then the best part his clutch cable broke and launched his bike into the back of an old VW Rabbit. The driver went thru it's back window over the bars and his buddy on the back went right over the top of the car. Still to this days that's one of the funnest things I have ever seen. So reving to show off can be dumb and sometimes dangerous.

A real neutral drop is doing it from a stand still. Put it in neutral, floor it, bounce off the rev limiter, slam it in gear. Bonus points if you dump a gallon of bleach on your tires first.

@SmoothButter ..... yes you can but, respectfully, watch out for the auto tranny - if your revs are too high it will launch you once you shift into drive....as per my post above about a Mustang GT that rear-ended a vehicle at a red light after "rev bombing".

The concern is the fluid flow within the transmission in neutral. Is it going where it's needed? Hopefully, someone knowledgeable about the subject can interject.

as long as the vehicle is running, transmission fluid is being pumped through the transmission. the only time the fluid is purposely not running to a certain place is when a clutch pack is not meant to be applied. in fact, the same clutch packs are applied in both neutral and park, just park also has the parking pawl brought into play. so if its safe to rev in park, its safe to rev in neutral

Bikers on Harleys? Ever hear a Harley horn? I could raspberry louder. Those horns belong on bicycles.

As to why, I was with other mustangs in a 4th of July parade and little kids asked for revving. I hit N, revved, and a few times rec’d APPLAUSE!! One of my favorite Mustang moments. Definitely in my top 3.

Yep, I worked at a Harley shop. All bike horns are like mouse farts, uless you fit an air horn like I did.
But my point was the stupidity of rev bombing in an emergency.

I had no idea you worked in one. Was going to mention the double trumpet horn with a little air compressor. My dad wanted one and put it off. By the time he was going to purchase it the catalog no longer had it. So he used one from a later model. Not much louder. He gave me the bike. Dang thing runs like a charm. Horn still junk. When people make fun just say it's nostalgic.
