How often do you over-rev?

It seems like every other month I over-rev my car, invoking the limiter.

I've probably done it maybe 5 times.


What I've found is that to avoid this unpleasantry, I often shift too early during my power runs just to "make sure" I don't over-rev.

I wish I could get a beep or something, like an RX7 I once drove.

If you are revving via the throttle and hitting the rev limiter, then you are not "over" revving, you are simply revving to the limiter.

over-revving (mechanically) would be revving the engine beyond the limiter by mis-shifting.

nothing wrong with bouncing off the limiter once in awhile .

There's no reason to hit the rev limiter on the street - it takes you past the sweet spot with unnecessary (albeit small) stress on the engine. Lower the stereo and/or get a louder exhaust and listen to the engine - you should be able to go by sound once you get used to it.

I've never accidently bounced off my limiter. When I've done it, I've done it on purpose.

I'd say I hit the limiter (that's not over-revving) about 10 times a week. It's always intentional, though.

As KrisL said, it's not over-revving, but I've hit the rev limiter only at the track, where I can't hear the engine well with the helmet on and the windows open. I've never over-revved (from a missed shift).

I wish it was everytime I drove it!!! But, since 07/2004, I've run into the limiter maybe 5 times or so. My daughter (when I was teaching her to drive a stick) downshifted into 2nd instead of 4th once. It sounded pretty bad, but, I don't think she over-revved it. I reached over & just yanked the shifter out of gear without looking at the tach. I don't even remember if we were going that fast.

I do wish the tach was a little different. I wish the redline was a little more towards the 12 o'clock position. When I get going, I have to keep an eye on the tach so I know know when I need to shift. For some odd reason, I can't 'hear' when it's reaching redline yet???

I rarely "hit" the limiter. I shift right at it though.

You're right. I should have said "revved to the limiter". I never mis-shifted into the deep red zone.

To me, hitting the limiter means you lost acceleration.

I think one SHOULD go past the sweet spot before shifting. Otherwise, the upshift would sink your rpm's too far BELOW the sweet spot.

Your sweet spot must be too small....

Neither does revving "past the sweet spot" because you can't manage to stay in the sweet spot on the upshift.

I may "hit" the limiter, but I don't bounce off it... usually.

Did it once or twice, just wanted to see what would happen. It's fun to take it to the limit.

I've hit it once. I'm still used to the sound and feel of my MR2 that I had
for 12 years. This car is just too smooth. I was merging onto I-95 w/
the radio up and I remmber wondering why the car stopped pulling. Then
I looked at the dash and saw the tach and "2" for the gear!

Someone posted earlier about turning the radio down and getting a louder
exhaust. They're right!

"Sweet spot" -

It will depend on the car's torque curve shape and gearing. IMO, the idea is to minimize the total area UNDER the HP curve. If I have to go a bit past the max HP point on the curve so that the upshift would drop me into a spot that minimizes that total area, I would do it. That said, hitting the rev limiter would slow you down enough so it won't pay for itself - you should shift right before you hit at the latest. I only hit the limiter at the autoX when it makes no sense to upshift to third for a second or two and than having to downshift again into 6K rpms or so...

Exactly. The moment you shift you are no longer at max HP, but it's a compromise to keep the upshift closer to the max HP point as possible.

Maybe the confusion between BahnBaum and myself is about "sweet spot". To me, it means the point of max HP.

Prolly right.

Either that, or it was my failure to Just Say No in college.....

Yes, I hit the rev-limiter often, especially when I see this sign

Damn, I'm green with envy just looking at this sign. You should have your limiter removed.

There's a rev-limiter in my car, but the speed is not limited
