A stock G won't rev that high - it has a rev limiter set at 6600... Even re-flashed ECU (at least Technosquare), it will only go to 7100 rmp. Are you sure you didn't miss-read your tach? If not you have an anomaly!

The thing I don’t understand is even if you could get to 7400 rmp, how the hell do you not notice until you “finally looked up”??? The engine would be screaming by then! I have TS ECU re-flash and I rarely (if ever) go to 6500. Even on a dyno at 6500 it’s apparent (by sound) that it’s pushing hard. How do you get into those rmps by accident? I think you miss-read your tach.

 

The 6 speed has a 7,200~ rpm redline I believe.

 

Are you sure? I wasn't aware of that... you have a MT, is stock redline 7200?

 

He has the "old" model G35 which has a very low rev limit of 6600

 

I have the same model year as you... but my limiter is 7100 (only due to ECU tweak).

Until this discussion I was unaware that ’05 was any different. I felt compelled to find out so called a reliable source - low and behold ’05 MT is higher, but not to 7400. So the question still remains: the original post of 7400 rmp – was this an anomaly or a possibility? (BTW, we don’t know whether his car was MT or AT or what year).

None of it really matters, I’m just perplexed that the car would rev that high, and how you wouldn’t notice far before it did (if it could).

 

The new redline is at 7000rpms. The new version also gets a programmable rev light indicator. you can set it so it starts blinking at a certain rpm. He should have hit the fuel cut off but maybe he didn't quite get it high enough. Some of the other members with the older pre-05 engine has hit 6700 without hitting the rev limiter (without ecu tweaks) so maybe the tachometer isn't 100% accurate.

 

listen abusing any machine will break it faster then not too, but as long as you keep fresh oil in that motor, all shall be well.

 

After 5,000 RPM the engine is screaming on the 05 6MT. The basic difference between 6,500 and 7,000 RPM is hard to distinguish unless you are running your car into redline constantly and know the tone very well. I've been driving my car hard at times, mostly empty freeway on/off ramps and when I am cornering hard in second gear sometimes I will think I have a little more room to stretch the engine, then bam, I hit the rev limiter. It happens, not on purpose, but it can just happen and your first reaction is to look at the tach so you know how hard you just ran the engine. 7,400RPM may not be the most accurate number by the poster, but its close enough, I've seen my car hit 7,200 RPM and thats after I hit the rev limiter and took my foot off the gas.

 

Technosquare recommended to me that if you hit the limiter(7100), do not keep it there.

 

I hit 6900 about 300-400 over redline so i think 7400 is reasonable for 05 6MT

 

Thanks for the advice, I thought it was healthy to run my car into the rev limiter for at least 30 seconds before shifting

 

{edit}

I have a stock 2004 6MT, the fuel cutoff is at 6800. The actual red line starts at 6500 but limiter is @ 6800.

 

Absolute nonsense. The life of the engine, transmission, rear end, u-joints, brakes and suspension are all related to how hard you drive the car. I you plan to keep it a long time it is smart to treat the car well. Drive it hard and it won't last as long, it will have more problems and it will show signs of abuse. Whats important is whether or not you care. If money is no object and you want to drive it to its full potential, go for it. But don't kid yourself, driving the snot out of a car is not good for it.

 

Generally true... but some cars are going to show more signs of trouble than others. Nissan has a history of creating some pretty hardy sports cars. Not to say that they can withstand a ****-load of abuse - but they are designed for performance. I don't baby mine, but I don’t beat it up either… and for sure I take good care of it! 3rd Nissan I’ve owned and 5th in family.
