Does shifting at redline..

[5Toes]

Does shifting at redline wear out your motor faster?

I know alot of people here drive their cars like they stole them (me too sometimes) and I am curious if you can still get 250,000 miles out of an m20 or m50 while doing this.. granted that you do all the maintenance on time, etc.

Yes.

[kronus]

yes

[Hick]

No, you cracked the secret all car manufactures didn't want you to know!

[LJ851]

An good example of this would be a SpecE30 car. Stock engine driven hard and well maintained.

[pandaboo911]

yes, unless you have a rotary under the hood

So what exactly will wear? Obviously assuming that the engines not cold and it has the right weight oil.

An engine is wearing any time it's rotating. At redline it rotates faster, so all oiled metal contact surfaces (all bearings, cam, rockers, valve seals, rings) wear faster.

Wear items will wear at an accelerated rate when they are exposed to extended periods of high strain. The wear items are pretty much anything that moves in an engine, i.e. piston rings, pistons, bearings, valves, etc. etc. I mean you can look at it as simple math, a piston that is revolving at 7800 rpm is experiencing twice the travel that one will experience at 3900 rpm and so on and so forth and that is not getting into the details of the more sophisticated physical strains subjected to a moving part under load. So yeah, if you drive in the red zone, you are wearing out your engine faster. If by maintaining it well you mean replacing ALL the wear items regularly, well then you are dealing with almost a brand new/freshly rebuilt engine every time

Wait so would redlining a e motor that redlines at 5 compared to an I motor that redlines at 7 is one wearing fasr or the same

There will be slightly more wear on the engine if it is routinely taken to the redline as opposed to shifting at lower engine speed. But probably not enough additional wear to make a significant difference in engine life.

Using NOS at the redline will wear it out even faster ;)

Well, you only live once so. Redline all day.

There is no room for intellectual observations in this thread!
