Break In Period?

Higher RPMs? I'm pretty sure that regardless of how your cars computer learns your driving style when you push the pedal all the way down the same thing happens. I won't go in to open loop vs. closed loop because I don't know where the ECM makes the switch on this car. But, in your car that has been babbied carbon deposits are EVERYWHERE (robbing power and economy). Higer revs means more, faster air moving through the engine. This keeps things cleaner and working better. Maybe the cummulative load of driving like you stole it over say 100K miles might weaken something like a connecting rod or valve spring but probably not to the point of failure.

Anyway the reason that engines that have been driven hard make more power at WOT (there is only one WOT setting regardless of if you drive like grandma) is because the motor is clean(er).

Studdies have proven that the ideal engine RPM for longevity is 1500. So if longevity is all you care about enjoy driving your new 40K sports car like a lawnmower.

That being said it won't hurt anything to obey the published break in procedure. It will give you peace of mind and a chance to learn your new car. If you shorten it up a bit it's at your own risk but odds are it won't hurt anything.

I remember reading horror storries about Evo's not breaking in properly and leaking constantly. But I never came accross anything like that on a VQ.
