: No, I didn't mean NO maintanence at all, but some are required, like changine oil once in a while.
Oh ok, you were using the term "NO maintenence" loosely...well then I agree with you there, I've seen some badly abused honda engines keep on chugging (i.e. no oil change in 20,000+ miles!!)
: No, I'm not a mechanic, but Honda's engine require less maintance than probably any other car I can think of the top of my head..
: If Honda designed their engines to achieve peak HP at such rediculously high rpms, don't you think they took this into consideration and at least put some effort into making sure the damn thing lasts?
Sure, they'll make an effort, but the original post seemed to imply that you could rev the thing at 9000 rpm for a month and have no ill effects. I'm sure the engine will take 9000 rpm much better than most other engines, but it is still going to shorten the life of the engine if you run it that hard for that long.
: It's funny to say an engine with a 9000rpm redline (S2K in this example) achieves 240hp at 8600rpm, and would have problems being kept there for periods of time.. That's the purpose.
Sure! Like I said, they design it so it won't blow up at 9000 rpm (i.e. not throw a rod, maintain valve-piston clearance, etc).
: No, it's not a frictionless surface of course, but the stuff Honda uses in the NSX 3.2 is just amazing, can't really name all the details, but yes Titanium conn rods is one of them, along with other goodies specifically designed so that the engine withstands such high rpms.
: Of course there's a difference in engine wear of shifting at 3K, and shifting at 8K, but I have no doubt in my mind that that's what the engine is meant for.
: In other words, revving that little 4 banger to 9000rpm is probably the same as revving your I6 to 7000rpm.
I agree with all of the above...what are we debating again? :)
: I'm sure that's not a deliberate attempt by Honda to prematurely make you blow up your engines right after your warranty expires.
Well that's assuming the original post was legit. Sure they may do it, but I'd have to see it to believe it. What happened to break in periods!??!? Rev the thing at redline for a month!?!??! What do they have, this big warehouse full of running engines and gasoline with a big exhaust pipe coming out of the top!?!? :) I'd REALLY like to see that one (as I'm sure the EPA would).
Oh well, who knows :)
