The redline thread reminded me of this question.
Last time, I asked "What if I never go above 5k?" I got many horrified responses.

This week's question is: What if I always keep it above 6k?

Intuitively I think that the only issue with always holding it at 5k would just be less gas mileage. I could be wrong though.

At 6k (or above, always), would this still be the only issue? What about seal wear, or tranny issues? Looking forward to hear your thoughts.

More RPM's = more stress on the engine components. The Renesis was designed to rev to 9k+ routinely. However, it is not a race engine designed for prolonged high-rpm operation. I would expect that an engine that is run continuously at high rpms (like a Star Mazda engine) would have a reduced life, and should have more frequent service.

In track days, autox, spirited driving, there should be no significant effect on engine life. If you are endurance-racing, or driving for prolonged periods of time above 6k, expect reduction in the life of the engine components.

the best rule of thumb i can give is to vary the rpm's regularly

don't *always* lug under 5000, but don't *always* drive at 6000rpm either

a variety of rpm's would be good for the engine in the long run

something must be wrong with your car if it is lugging above ~1250 rpm.

lug in my context means purposely keeping the rpms low (in this example under 5000rpm)

maybe granny shifting is a better expression? :D

my car's perfectly fine btw, thx for your concern :D

i prefer the term "casual driving"

sorry if that came off as a bit abrasive. there seems to be a myth running around here that 8 is incapable of operation under 4-5k rpm, and the engine will actually lug if you try. such dramatically inaccurate comments kinda irritate me. glad to know your car is working as it should

driving under 5k is fine. Now always driving over 6k will probably effect the tranny before anything else.

If you always hold above 6K, you will break the seventh seal and unleash the apocolypse. So please for the love of budah don't do it :D

as far as i know (haven't studied buddism very much), the seventh seal is part of the christian new testament...so what does buddha have to do with this?

and from what i understand from my limited studies, buddha typically shifts around 3500rpm for normal driving, and redlines it once per startup to keep the carbon build up at bay, and averages 18.5 mpg. he also thinks the interior is comfortable, but wishes the seats were a bit wider.

It's a little known fact that the "Enlightened One" is the key to the seventh seal. I believe I read that in the DaVinci Code. The whole thing is hidden in the Vatican Archives. You're right though he does crave a wider seat and finds the head room a little tight. Another little known fact, Buddha was quite tall :p
