I usually find it easier to drive the 8 around at higher rpm than my rsx-s, cruising speed with the RSX is roughly the same RPM as the 8 however, it feels a lot rougher on the 4 banger than the rotary. With the rotary, I just want to keep reving it and it feels like I can rev past the redline while the piston engine, it sounds painful at high RPMs...

Vibration????
A while back right before the RX-8 was first released Mazda engineers were showing off the Renesis and had it running on an engine stand. They then put a glass of wine on it and revved the engine to ~7K and held it there. The glass didn't move or shake and it was reported the wine barely even rippled. (I think this was in the R&T back in '03 where Sam Mitani wrote the lengthy article when it was still in pre-production, it had the yellow 8 on the cover.)

The only thing scarry about 6000+ rpm is:
How fast the fuel goes down
How smoothly the car pulls
How slow the rest of trafic seems to get
and how stupid we look grinning and smilling at the tach.

At least that is my interpretation of the feel of the car a high speed.
And yes I am at 94K when I shift through the gears from 1st to 5th to get over 140mph.
I have yet to get higher speed in the straights. Run out of road.
I am hoping the new tuning and the REVi intake and ram air duct will give me a little bit quicker acceleration.
You may not be able to test a ram duct on a dyno, but after watching the news regarding the hurricanes, if winds of 60 to 150mph can do that much damage, creating that type of force artificially by driving the car that fast has got to really ram some air into the car. It just stands to reason.
I am also toying with putting in 5.+ ratio rear end to help get the car quicker in the straight and up to high RPM faster.
When I first got the car stock, it could out run anyone else in the corners, but in the straight it had a bit of a challenge against some of the turbo cars.
By the way, against the Boxter, that Porsche could not come near the 8 under any circumstances.
After I took out the stock exhaust, the 8 just walks away from everything else in the straights. Right now I need to be able to hold my own in the straights so I don’t lose the gains in the corners.
I also need to trust the car more coming out of the corner leading into the straight, I might carry more speed into the straight and get better times. But all in time with more practice.
For the record, it runs silk smooth to redline. So much so, I have to keep an eye on the tac to insure that I don't hit the limiter.
Since I talked about high RPM we are still more or less on topic. More or Less.

The 8 revs more smoothly at 9k than most piston driven engines at 4-5k.

I'm more scared to take a piston engine to 6000 rpm (any piston engine) than I am to take a rotary to 9000 rpm. Big deal. You could drive around all day there and be fine.

If you think about it, that is why you see the power band on the rotary start around 6K because the rotors are at 2K. That is the same RPM on many piston engines when they start to develop their initial power.
On the track, if you don't keep the RPM between 6K and redline, you get left in the dust.
Some of us are looking to raise the RPM limit for that very reason. At 10K the rotors are only at 3300K. The only thing that is high revving is the crankshaft.
That might put a little persective on the RPM issue regarding the rotary engine for you.

13B at 6000 rpm's = 12,000 combustions per minute
4 cyclinder at 2000 rpms = 4000 combustions per minute
Not equal...

Yes. Fun begins at 6000 rpm.![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
