Does shifting at redline..

hahahaa

wear is the square of difference of speed.

2000 rpm last 16 years.
4000 rpm last 4 years.

hee... I almost tried to respond to this thread!

Because... not racecar.

Redline all the time seems extreme, and abusive, esp on the road... I always feel kind of sick when I hit the limiter..
In m20, doesn't seem like u lose much shifting a couple hundred below red.

I was aware higher rpm operation equals more wear.. I was curious how much more wear

[dnguyen1963]

If you redline all the time, I would worry about changing the timing belt religiously and not about the other parts wearing out.

[coldweatherblue]

first of all, a maintained m20 loves to spend time at upper rpms.

second, i think it's common sense that running an engine at redline will expose it to more wear than keeping it at 2k rpm. meaning.. slightly more wear...

however i like to drive my car, and in almost 10 years of daily driving an e30 and taking it to redline probably once a day (you all know that fun 2nd gear section on your commute where you can go from 20-50 fast and its fun but not really "speeding") I've never had a problem or worried about wearing the m20 too fast. As said above, wear is mostly from cold starts and failed maintenance on the part of the owner. if you save the r3vs for 1-2x daily when you're having fun driving your car, i wouldn't worry about the wear because you're getting enjoyment about your car.

It's not something I am concerned with I have Had several motors over 200k and still take them to redline most engines it's the valve train that's the limiting factor on rpm

Truth.

My sedan had 250k when the timing belt snapped. Someone swapped it to a 5 speed and installed a LSD rear who knows how long ago. My point is, that I'm sure that car was used and abused, and sadly was taken out on a technicality.

I had an impreza with a sloppy ass shifter this was back when Subaru engines were non interference and I money shifted it and it revved to like 8500 and it was fine

How is it not?

the others explained it well, but if you like reading more

It's not gay if the bearings don't touch.

:rofl:

[Holland]

bearings don't touch. that's why you want good oil pressure, and why losing it is bad.

In general, how you maintain the engine will have much more of an impact over its longevity than how you drive it. Maintaining it religiously and beating the piss out of it (after properly warming it up) will be better for it than skimping on maintenance but babying it.

Plus, you'll have zero carbon build-up. My 250k M50's valvetrain was spotless when I peered into the head. :rofl:

Especially remember to always keep dem new diesels at low rpm's, gotta keep dat DPF temperature steady!

[Exodus_2pt0]

always assumed it was because it was a decade old mini van....

All about how it's driven.

I have a 94 Trans Am with 5x,xxx miles on it that I baby. My father bought it brand new, and I have taken it over. I get on it probably once or twice a month in the summer when I have it out, and on the first hard accel it will smoke like a diesel. Just on the first pull,,for about a second, after that nothing. Granted it does run a bit rich, but just goes to show that you do get a build up under easy driving conditions, and once you get some air flowing through, it will clear it out.
