A rotary question.
 

Is it ok to keep revs over 5-6K for long periods of time? Like say a 100mph blast on the freeway for 20 miles or more? I've got an s5.

Is there anymore wear on a rotary vs. a piston motor?

rotaries loved to be revved but yo have to be careful

youll be fine
just watch the temperatures

^ This has always been my understanding as well. Many club members track and AutoX their RX7s, and as long as you can keep your temps down you should be safe.

I've done it a few times on my S2. Different motor, but it's got 200 000 km on it, and it didn't seem to do anything to it. I've also done 12 hours on a highway in a day and had few problems. Of 4 times I've done it, I had a little temperature creep once, and just took it slower. I usually end up driving on the highway in 4th, I don't drive fast enough to keep the revs over 3000 in 5th often, and I've found I get awful fuel economy with the revs low.

That's exactly why I asked. My syncro between 4th and 5th is starting to go so i'm trying to get by without going into 5th on the freeway. In my vert, 100mph is about 6k. I really don't plan on going much faster but it's reassuring to know that I still have a couple thousand r's left to play with.

You really get better mileage with higher revs?

I've gone from chicago to palm springs in 2 days and my s5 seemed to love it. By the third fill up I was getting close to 400 miles per tank, I was drafting a lot. I do tend to drive on the faster side on the highway, just watch those temps.

I agree , Never had a problem.
