Someone at a car show told me its horrible to rev a car when its not moving. If its at operating temp why does it matter??

There is 1 word to describe the person that told you that: Failure

I've heard its bad to OVER rev an engine while in neutral... but it's also just as bad to over rev it while in gear too.

I would have looked at that person and said "You're an idiot."

Just don't sit there bouncing it off the rev limiter for 5 min straight. You'll be fine.

It is bad to "over" rev an engine without any load on it. Take a computer programming tool, hook it up and watch the knock counter between N revs and in gear at the same revs ... you get a lot more knock from the motor when there's no load. The reason for that is the mass inertia ... when there's no load ... you're spinning all that power at the crank and the energy has no where to go but back out on itself. When you're in load and spinning all that power, the energy gets transferred out through the tranny to driveshaft to diff to axles to wheel ...

i wouldnt make it a habit. especially when its cold. once in awhile shouldnt hurt anything but i wouldnt go WOT.

just dont rev it high, like 4k or higher. why would you be reving an engine past 3k in neutral? so how high was you reving your motor that made him tell you this? so yes it could or no it wont. just depends on facts you haven't told us.....

I enjoy setting off alarms in parking structures once in a great while. Once in a while doesn't hurt, but I do get a kick out of it when i do it on accident.

As far as doing damage to the motor, it's bs, Just don't bounce off the rev limiter for eight hours, you'll be alright.

Agree with what everyone else on here said. That guy who told you that and his friends who agreed with him should all do us a favor and throw their car keys off a bridge and never come around a car again lol.
