On my supercharged 350z, at the drag strip I misshifted the 3-4 into a 3-2 at redline. the tach needle swung all the way around to the 6 oclock position momentarily before I got the clutch back in. Fortunately no damage.

Pucker moment lol

Is 8200 RPM the default value?

No. The stock limiter is set at 7500 RPM.

You can't beat entropy... all mechanical systems will fail...

An engine's "redline" is essentially the maximum RPM in a given gear where peak torque and power have been surpassed, and now the engine is producing less useful work and and more heat, further contributing to (eventual) mechanical failure.

Running any engine at or beyond redline for long periods of time can kill it in short order -- consider the planned teardowns for dedicated racecars than run the car to its limits all the time.

But, you are not running the car for sustained periods into the red -- you are shifting at or below the (more or less empirically established) redline.

Pick any gear and drive all the time past the line, well into the red for sustained periods, and you will kill the engine; on a related note, run the RPM's high enough (well beyond redline), and you'll break the oil pump.

On that note, if you shift the car at redline frequently, while it will put more wear and tear than never running it hard at all, it would also be a lot less fun if you never ran it up to its limitl. In other words, stop at the limit, don't hang at it for a while or go beyond it.

Will a "babied" car last longer? Sure. Likewise, a machine that never runs also won't break, but it won't produce any any useful work either.

On a well maintained modern engine, you might see well over 250K miles on it; on one that is run hard, but not beyond the established boundaries, maybe 150K.

You'll probably buy a new car before that anyway.

So, in short, beat on the car as you like (within the limits with which it can be logically beaten), do the regular maintenance, and you should be fine.

Thanks, I went in car and it was set to 7500. I brought it down to 7000

You brought the shift light down to 7000. You'll still bang it off the limiter at 7500.

^^^ This

I have mine set to 7.8K.

I'll take it on faith that those revving to 8K or a bit higher are not risking the oil pump, but 7.5 is certainly fine.

I bang into and bounce off the rev limiter 20+ times a day.

I redline after I startup to get the oil flowing and get everything up to operating temp quickly to reduce engine wear.

I needed a good laugh, thx

Psch...... I do the same, but in reverse. In takes maybe 2 minutes & I'm good.

Indeed, was aware of that bit LOL.:driving:

L0L! When u chirp 5th, its hard n0+ 2 do! L0L! :icon14:

I don't redline it every day, but I also don't ever shy away from it. I bought the car, I'll enjoy it and the sound it makes. Every few days off a stoplight on a 50+ road I'll tease the limiter a couple times.

It's relatively hard to do damage to our stock 7AT, if not actually impossible without attempting to shift into Reverse or Park while moving. We're probably all going to be more at the mercy of random engine issues or general unavoidable age than we are from issues directly related to beating our 7AT around.
