I agree with you Rusty. I have hit 6800
rpm with my old 13B and believe that if you took a 13B and spent another
600 on lightening and balancing the rotating mechanism for say 9000 rpm, you
would produce at least as much power as the Renesis. On the other hand my
"New" model is already 14 years old, so if starting from scratch, I would
probably go for a junkyard Renesis. Still waiting for the first RX-8 in
this area to get rear-ended (no injuries of course).
Going to take a long nap! Yawn

Truth be told, I don't
think the Renesis will really outrun the 13B in our rpm range. I think
Mazda just made a better intake, and turned up the rpms. There are
certainly some improvements in the Renesis, but it's not light years ahead in
performance. It's absolutely possible to get 200 HP from a 13B at
less than 7500 rpm, with nothing more than a street port, and a decent intake
and exhaust. Tracy was doing it, and I expect to be as
well. All that being said, the Renesis is clearly the future of the
rotary, and there's no downside with the exception of a bit higher price at
the moment. I think the Renesis is a slam-dunk choice for folks starting
out now.
Cheers,
