constant high rpm's?
This may seem like a newb question, and it partially is.
But the RX-7, one of the advantages is that you can shift at a abnormal high RPM range, but what about constant speed driving?
Is it better to shift high, and then when you achieve the speed you're going for like 5 miles, shift up again so you aren't constantly stressing it? Or is it fine to keep it at like 4 or 5k or so for those miles?
This is something I've been wondering about for a while, finally bothering to ask.

I agree with the shifting low, that is what i do but i also have woundered about the Rotary's high-rpm lasting ability's.
Will they last with lots of high-rpm's?
I ask because i am used to big V8's which would just blow-up over 5000 - 6000rpm. So going to redline at 7000+ just seems like a death wish.

LOL, well the redline STARTS at 7k on my car, from experience with bent valves on one of my other engines i never take an engine past redline and try to stay a long way from redline especially on old engines. Much less go to the end of the tach.<o:p></o:p>

so the thought of being able to rev tot he end of the tach without harm is a foreign concept to me. Though with no valves i there is not as much to get hurt, still...

Well I know that gas mileage will be better below 4k, but - what about engine health? Does that strain the engine at all if you keep it at 4k or higher? Or will the only consequence be that lower MPG?
