Does shifting at redline..

[nando]

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.

Bearings are NOT a metal contact surface

Most engine wear is from cold starts, not revving it once warm.

Jesse usually shifted at redline with no problem, but he was running titanium valve springs.

Look at it this way, if you fap furiously fast once a month, using the recommended weight lube, you will create x amount of friction between your palm and penoose, thus causing wear.

If you fap every day for a month with slow even strokes, you will create the same amount of wear and tear on your dick, granted over a longer period of time.

Conclusion, win-win.

owners manual specifies that part of preventative maintenance is to run the motor to red line occasionally.

^just because the manufacturer says so dosent disprove that its not bad for the engine. it could be prescribed for the sake of preventing something that is much more likely to break than the engine itself. or they could be hinting to enjoy the car every now and then ;)

Thanks jlevie for a great answer.

good thread

Gotta float dem valves...

I know this seems like a dumb thread

But I was curious how long an engine can last while being maintained and driven hard

Who are you going to believe, the engineers that designed the car or some guy on the internet?

What if the guy on the internet is one of the guys who designed the car?

Drive it like Fast & Furious

M42 actually wears out faster at lower RPM. In it's never-ending quest to mature into an S14 it craves the redline.

How is this so?
