How high to rev before shifting in each gear?

ZeeBabar

There are guys who want to redline once a day and others who do it frequently. It's fine unless they con themselves into thinking its good for the car. The car is perfectly satisfied with gentle shifts, get it into 6th at about 60 and stay in 6th all the way to 130+ and it would not mind.

Guys who redline often and get to believe the car likes it are like guys who want to do it every which way they can with a woman and think the woman likes it. They get blown engines and short relationships, car or woman does not matter.

You sound like you need to get yourself a vette or sum other Gov't Motors powered car. These Nissan engines don't make any torque 'till high up on the RPM band and redlining it to the stock rev limiter ain't gonna hurt it.
Car = Machine.
Your analogy with women = FAIL.

Exactly. That's why the rev limiter is there- to prevent damage. Do you think Nissan would sell and warranty a car that was able to be damaged by frequent trips to the redline?

If hitting the rev limiter caused people to blow motors, where are all of the "Guys I popped my motor" threads?

I wasn't about to touch the car=woman analogy because there's a whole lot of stupid there I don't even want to deal with.

Until the advent of computerized engine controls, the only rev limiter was your foot and the physical limits of rods and valve springs. I owned six vehicles before my first EFI car. Only my '72 Cutlass had rev limiter of sorts, it would float the valves at about 5500 rpm. Aftermarket coil packs sometimes had rev limiters built in.

As for the dyno comment, that was half-assed. To be completely-assed, you shift at the point where the rising torque in the next gear equals the falling torque in the current gear to achieve maximum acceleration.

Otherwise, shift whatever the hell rpm you want that's allowed by the ECU. I grandpa my G for the most part because I'm not Big Bank Hank and can't afford to fill up every other day.

Agreed, 6th gear from 55MPH+ all the way to 150. And also agreed that everyone here who 'enjoys' redlining their cars and thinks their sports car can handle it must also partake in domestic abuse/rape/sexual assault.

Why? I think Chuck summed it up..."Exactly. That's why the rev limiter is there- to prevent damage. Do you think Nissan would sell and warranty a car that was able to be damaged by frequent trips to the redline?

Errr, I'm sure the people that have had fuel starve said the same thing.


Just remember "can" doesn't always mean you "should".

So what exactly do you think happens when you redline the car more often? Why do you think the factory put the rev limiter in? Why do you think they put it at 7500rpm if the car couldn't handle it? I'm not saying go out and keep the car bouncing off fuel cut your entire daily commute, but the idea that the car will damage itself at redline is asinine. It's right up there with the mind control chemicals in the airplane contrails and vaccines giving you autism.

Haha, I'm with you.(Shiiiiii once I get a tune I'll be doing some 8k shifts)

But people that think they can redline stoplight to stoplight on a daily basis without any consequence at some point it's going to catch up with them.

And you will then find out why the rev limiter is set at 7500. Don't raise it. The internals of the oil pump will self destruct and your motor will make a very expensive noise.

That was a snarky post mainly aimed to mock the poster's posited sentiment that people who willingly & freely redline their cars (often) were likely to treat women in a predatory fashion. Also, the notion that one should use 6th gear to accelerate from 60 - 130...

Yeah, that's pretty funny.

Putting a lot of load on the motor at too low rpms is far worse than hitting the factory rev limiter.

6th... worthless gear. I literally never use it. Hell, I keep it in 4th a lot of the time just to avoid speeding too egregiously.

It's even worse on my bike. 3rd is cruising along at 70mph, 4th-6th will get you arrested.

I hate lugging engines along at low rpm which is probably why my fuel economy is such shite.
