My previous follow-ups went back to a poster's assertion - "Whatever you do, don't keep those rpms in the 2-3k range on your 911. It's actually bad for these motors.. moreso in a .1 which you have.".

Was the poster just using shorthand for "lugging"?

Or, were they saying that even non-lugging "low RPMs" are inherently harmful to the Porsche flat six?

This is an instructor/parent worried about their student overrevving an engine and way too basic for a 911. My basic answer is don't lug it and don't over rev it but definitely don't be afraid to regularly drive a short stroke relatively high revving flat 6 between 3500 and 5500 rpms. And roll in gas with rpm. Unless cruising at a constant speed your foot should be constantly moving.

That was me.. the original poster stated "I was always trained to always keep RPMs between 2-3K"

That implies the car is rarely if ever above 3k. I don't see how that is possible without lugging it. Cruising around in that range is fine but if that is your acceleration..

These cars are built to be driven and need to be more often than not. Anything less and she will taunt you with all sorts of issues.
