Mine came with a warranty so.....

Related, I'm currently dating Katy Perry but I've agreed not to touch her boobies (or anything else) so I can preserve her for the next guy.

Several years for the F458, but I bet very few have many miles. Used Ferraris appear on the market with a small fraction of the miles of their Porsche contemporaries, on average.

I hate to say it. Though it has already been said before many times. The garage queen problem you mention is largely a US problem. In Europe and ROW quite a few are driven hard and a lot.

My personal experience is 30,000 kms yrs in under 2 yrs, most of that spirited canyon carving on hot days and quite a few track days (some of them in searing heat above 100 F). The 458 engines are indeed almost like a race car. I have abused the 458 more than I have any other car. It just takes it. I also have some examples of people who push it even harder than me. Still no engine problems.

I have seen 458s here with over 50,000 kms but agree with you that miles on them are still less than porsches. But I have every reason to believe that the reliability will continue on these cars.

Go to 9.10. According to Chris the answer to your question is because they are porsche I am sure they will make the engine reliable at 9000 rpm.

458 engines have been revving to 9000 for several years and have proven rock solid so far. If ferrari can do it, porsche should be able to do it better.
I think a V8 that revs to 9000 is a very different proposition than a flat-6 that revs to 9000 before bouncing off the rev limiter.

Agreed.

Been there, done that, many times myself.

But the question is not whether it can without blowing up, but whether how often it can without blowing up?

To the latter question, no one is really certain at this point. Probably not even the geeks at Porsche HQ.

I'm just hoping that it'll last 1 day more than my warranty.

One day less than your warranty would be better

GT3 motor would have to be 3.0L for that analogy to be on point. When S2000 increased displacement only 10% to 2.2L, they had to lower redline to 8,000.

As karimGt3 knows, people in Lebanon push their cars very hard.. All we have are fantastic mountain roads with slippery tarmac ... Only time will tell... I'm already thinking that I will keep this car for a long time...

We are talking about flat six engines; as an asides how does Ferrari do the same with a Naturally Aspirated V8?

Hell how do the developer's of F1 engines go over 20K RPM in developing the engines that will eventually make it into the actual F1 cars? I'm not saying that F1 cars reach that in actual racing - at least not yet!

Not sure either of those examples qualify as what most consider "reliable".

Mean piston speed. Guessing all very high, they just get there differently. Small cylinders, oversquare bore/strokes, smaller distance traveled in one orbit usually means more RPMs before reaching MPS.

Can somebody tell me what happens at 9000 RPM that does not happen at 6000 RPM?
