Thank you. If you're standing on the limiter at a stop for any reason whatsoever, chances are you're TRYING to hurt something on purpose.

 

im really interested to hear evidence of why free-reving an engine is bad for it...i have never once heard that

 

Long time ago I've seen a video on the world wide interweb about students (kids) trying to destroy a civic.
They tied something to the throttle to make it run at redline.
It just would not die.
Then they drained the oil.
It still took a long time for the engine to finally gave up.
It is probably still on YouTube or something.

IMO the worst you can do to an engine is to accelerate from a slow speed in a high gear.
Max load and low revs so less oil pressure in the journals = max chance to break the oil film = max wear.
No, the oil pump pressure is not what keeps parts apart.
Its the oil pressure you get from rotating a journal bearing that does this and it is much higher than what the pump puts out.
The oil pump just transports oil around.

Free revving is easy on the engine.
No load, high revs.

I'm partial to believe that free revving an engine doesn't harm it at all. All the F1 teams and LMP cars have a "warm-up sequence" that consists of free revving the engine. If it was bad for a car, I can't imagine why the race teams do it?

 

How many miles do they need out of a race motor though? It's not apples to apples.

 

I'd like to see some hard evidence. In theory, I can understand some of the concepts people come up with as to why its detrimental to the engine. And many do make logical sense, but i've never experienced or even heard of somebody blowing up or otherwise causing obvious premature wear on their engine from free revving.

Back up your claims and enlighten me.
