How often do you redline your Z? Is it bad for the car?
 

First off all, I have never redlined the car when it was cold, but every time I do redline it, I still think I am damaging the car in the long run even though its a sports car. I'm not talking about bouncing off the limiter either, just shifting at 7.3k makes me feel guilty.

Also, is there a difference redlining a 6MT and a 7AT?

You bought a sports car, enjoy it. Take care to do the scheduled maintrnance. U know what took me s long time to get used to in the 7at? Downshift 3rd at 65 mph, i came from a v8, jumpings revs like was hard to get used too...

Your car does have warranty? I wouldnt do it if the oil temp was over 215 or so but thats me.

If Nissan thought it was bad they wouldn't let you do it. It's a sports car with a high revving V6, enjoy it!

Says the guy from Dubai. :stirthepot: :icon17:

Not very often. Maybe twice a week. I actually enjoy driving it lightly. Its effortless acceleration.

don't redline it man, keep it under 2k rpm :icon17:

I rarely redline. I'm scared something will break tbh lol. 6k-6.5k is my spirited driving.

Bumping the redline every now and then will add some wear and tear but Life's too short to get all that worried about it. Going by what I've read, the engine will not hold up to a lot of high rev use (oil pump and valvetrain tend to crater).

Like zefaulter, I seldom take mine above 6-6.5k. But I grew up with relatively low-revving V-8s and anything above that makes me nervous. :)

Mutiple times a day. it was set there for a reason, if they though they would all be blowing up they would lower it, you think Nissan wants to be paying out a bunch of motor claims? Sold my 350z with 110k owned it since 60k, beat the living you know what you of it. now mines boosted and has take 5k hard miles, still havent gotten it out of my system yet :). I would only classify abuse as going all out for hours on a race track, on the street, no way.

This.

I hope your engine holds up for over 110k again. reading your comment is probably gonna make me redline mine today

I'm in a DE 350Z but...

I started autocrossing my car less than a year after I bought it. Since then, it is generally getting thrashed, or getting driven to place where it will be thrashed.

I redline my Z often. (I bought the car new at the end of 04)

I mean I've redlined it probably 20 times total since I've owned the car, and I've only put on 5000 km on her. I just feel guilty doing it, but it does sound pretty awesome.

I go to 6k maybe once a day or so though.

I will be parting out my full NA setup and with the drysump i hit 8300 a couple times without valve float, don't know how long it would like to do that though.

50K miles. I've done my fair share of redlining. I typically try not to bounce the limiter though (probably done it a handful of times).

I find that 1st and 2nd gear redline pulls are just the thing I need to get me revved up :yum: I wish my wife was that easy :icon17:

It's my DD, so I don't beat on it all the time. But it's rare that I don't have a few 5K+ RPM shifts on my daily commute. Only a few times have I ever done multiple redline pulls in a row. Normally, I like to beat her just a bit and then give her some tender loving. Kinda like the bedroom ;)

75k miles here on my 7AT and maan I love shifting right before redline especially 3rd, I call it My Miracle Worker ;) but all in all its GREAT Especially when you got a F.I exhaust setup(Or any of your choice) is like music to my ears when WOT :tup: also its my DD fyi

They car is a high reving car. It has a good bit of safety things on her. I have red line her a few times. I do it every once in a blue just to remind myself how well I can shift (not saying that I'm any good at it) and how bad azz my car is. I have gone 75mph and dropped her into 3rd just to haul booty no problem. She can do it fine. The only 2 emotions I have when I do this is the adrenalin (it's both literally and emotionally a rush) and the "ohh shi*t" when I have already got off the gas after the short burst and cruse by a patrol vehicle 5minutes later.

Put boost on your car, plant your right foot and try to 1-2 shift with an MT before hitting redline. :stirthepot:

Challenge accepted! Now someone buy me boost

:leghump:

7.5k every time, cause you can't keep your eye's on the gauge and the exhaust note is just wide open!!!!! You got to drive it like you stole it to appreciate what the care is capable of.

This makes me want a Z even more

Then get one.:tup:

in due time. and i like smoke every once in a while as long as it's not my rubbbers. you can go through a lots of $$ like that.

if i'm getting on the freeway and shifting under 7k, it's because i'm driving home from the bar. :driving:

Redline it away, just don't accidentally go from 3rd down to 2nd while you're redlining =P

if redlining it hurt the car, Nissan would have put the redline lower. Mine is reset to 8200 and I shift at the limiter 90% of the time. I have over 16000 track miles on it doing that.

Even if he did "Accidently" Auto Tranny won't let you ;)

Well the way this car is setup, you dont get your HP peak/powerband until 7000rpms. Torques peak is at 5200rpm. This motor was built as a high reving engine. I always shift a little after the powerband. Most people when they race shift at the powerband, + or -

But I aint saying its not damaging the engine. Just saying the engine was built to handle it.

Thats only when stomping it of course lol

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.
