Re: [AMC-list] Pacer motor mounts oddities

[Jim Blair <carnuck@xxxxxxxxxxx>]

The rotary is actually a single cycle engine. I had a 3 rotor motor from a Cosmo in my RX2's body with 2 turbos. VERY fast! (I got clocked on the Trans Canada at over 175 mph which was NOT it's top speed! That led to 6 months w/o a license and I sold the car) Running NO2, it would do the 1/4 just under 8 seconds. The RX8 turbo comes pretty close, but I no longer have the driving skillz or lack of fear I once had.
   I did build my own rudimentary EFI system that got it to close to 17 mpg in town.

Aren't Mazdas still using rotary engines to this day? Speaking ot Olds Toronado there was a great photo of Croft Trailers framed on the wall down on Navigation years ago. There was a Toronado.....NO BACK WHEELS, hooked up to trailer and it toured the country this way the trailer held up rest of car I guess, too much physics for me. I used to rent trailers there for swap meets and was always facinated by that photo.

  Couple o' things.
  The wankel rotary isn't a 2 cycle OR a 4 cycle, they are Wankel cycle.
 
  (In fairness, I tend to think of it as 2 stroke, but that's not accurate ;-)
 
  Mazda used the rotary in a full lineup of cars including the RX-7 and their various boxy japanese sedans.  After the various apex seal problems, all the sedans dropped the rotary for the mazda 4 cylinder with the RX-7 being the lone rotary in production at all for a while.
 
  2 stack rotaries are commonplace.  Even singlestack rotaries are used, but not in cars -- you're talking all of 75 hp or so.
 
  3 stack are common, racing and road cars, but not domestically.  They are usually ordered in from Australia or somewhere.  Can't make EPA, you know ;-)
 
  4 stack are, to my knowledge, not used anywhere except experimentally on stationary applications like their "spark assisted diesel" project for electrical generation.  Yup... a wankel running diesel fuel... except "spark assisted" -- talk about marketing spin.
 
  The 4 stack has a lot of the same kind of crank probs a straight 8 can have.  Too much load over too long a shaft, basically.
 
  Among the many reasons the rotary didn't take off were those crummy apex seals -- ironically, now that there's so few of them, they've come out with good seals and the problem is gone.
 
  Also, they never did get good mileage.  Ever.  That's why I think of them as a 2 stroke engine -- they chugalug the fuel.
 
  The new Mazda Renesis (?) is a production rotary.... 3 or 4 years now?   And no, you don't see  many of them.
 
  Just in case anyone was gonna lose any sleep over a stupid little japanese engine.
 
  Oh... and if you run one without a muffler, it makes absolutely the nastiest, loudest, and most-annoying sound I have EVER heard from an engine.  Talk about something that would invoke road-rage... that'd be it.
