driving below 2800 RPM = trouble?

[Jaxonalden]

With the weather we had here last weekend, I decided to take out the Box to "teach it the meaning of the word respect". I love that line from Carl the grounds keeper http://www.youtube.com/watch?v=JObTMW3RVf4&feature=related . Anyway, the opposite was true, I forgot just how fast that car can fly and just when I think I'm getting in trouble those big Brembos bring me back to subsonic speeds, I LOVE IT. :dance:

This much fun must be illegal is some Middle Eastern country's.

Could we change the title of this thread to "uninformed opinions maquerading as facts about IMS failures"?

Lugging and almost stalling an engine are not the same thing! Wear to cylinder walls, main bearings, piston rings, etc. does not cause IMS failure therefore arguments that state that high RPM causes wear miss the point.

There was one post early on that tried to give a reasonable (although theoretically only) explanation that links low RPM, variocam and additional force to the IMS that sounded like a good argument for staying on the high side of the variocam switch over point. But that is just a promising theory. Jake Raby's anecdotal evidence that one seriously beaten engine has not had IMS failure supports the theory but certainly does not prove it.

I like the idea of driving your car the way you want and not worrying about IMS. If it blows up then either warranty fixes it, you sell the hulk, or pay Jake. Simple and stress free solution.

^ actually you'd be surprised how many people were unaware of the pitfalls of driving at low RPMs in the wrong conditions. I've been on this forum and others for years and the possibility of this type of driving being linked to IMS failure is seldom if ever discussed unless you follow a more technical forum like Renntech.

I don't think you'll ever prove anything when it comes to these engines... like whether 10K oil change intervals are worse than 7K or letting your oil come up to temp will lead to a longer running engine. There are doubts about everything including Porsche's most recommended oil. Doesn't mean it shouldn't be considered.
