Thanks for the info, guys! And Rusty, Congratulations on the
(flying) RV3!
Now i have to get over to the SoCal RV list and connive somebody
into giving me a ride so that I'm truly convinced. If I fly in
the RV and don't like it (not likely), I'll go for the pusher,
even though I HATE sanding, but I loved how the Vari-EZE flew.
BTW, since I posted last time, I searched the list archives
again, and found Tracy's post on http://www.car-part.com. There
is a wrecker in Tampa that has a Renesis for $3k, but that
was the only one I found.
MessageI 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,
Rusty (must be Ed's nap time)
