Default Re: Mitigating Cold Start Wear

I would love to see the internals of a Ferrari or Lamborghini engine to see the size/design of their rod bearings. Clearly they’re doing something right, no?

Yeah just like German cars. But really because many cars rev to 9k and Iíve never heard of them spinning bearings.

They do, not unusual. Pretty sure their rate of failure is significantly higher-- just happens less frequently because there's a lot less cars, seeing a lot less miles, and a smaller percent see track use... and the owners don’t post on BMW forums, and generally just pay to have things fixed/don’t worry about it.

Would you like me to teach you how to utilize the search function?

Gentlemen. It was a merely a thought. It could be because I own a bmw but I have never heard of other car makers having rod bearing problems as notoriously as ours do.

Yeah, I did think about them having a lot less miles. But certainly they could not see less abuse. The Ferrari owners that do come on bmw forums end up trying to sell their lsb/lsb M3 for $42k.

When was the last time you saw a Ferrari with150k hard miles?

People beat the living sh*t out of these cars for 100k and then are upset (not you) that the bearings wore a bit of metal. They did a good job especially considering the time and manufacturing capabilities of the period. If anything Honda has it figured out with their high revving 4 bangars but I suspect many of those that are beat on regularly also have bearing wear Š la S2000.

Nothing will last forever and few Lamborghinis get driven often enough/hard enough to see this as an "issue".
