Dear Kevin ;

Thank you for your reply.
I have bought the Twinstarr manufacturing rights, all tooling etc..
We have made an ultralight version of the Twinstarr, called the Twinstarrlite, which meets the stringent European ultralight rules.
The machine is now a lot lighter and handles well. In order to make other engine option availabe, we are loking intensively at a single rotor Mazda
aplication, in the knowledge that the Norton rotary is too expensoive and apparently had some shortcomings (at least the earlier version).
I hope somebody can help.

I heard years ago that Atkins rotary made a single rotorversion out of a 13B, but it produced only 90 HP . I think nowadays with the 20B , fuel economy as
well as output may have been increased.

Sincerely,

Woody DE SAAR-

**** Hi Woody, I have been collecting single rotor info for 2 years now, mostly off this newsletter, however to save you a lot sifting thru irrelevant
material you can contact me for single rotor specific items . A lot of development has gone on in Australia with turbo singles where they race in the turbo 2
litre sports sedan class and Guru are seeing around 240hp at the rear wheels on a roller dyno. N/A REW engines are showing 97HP@ 8500 at the rear wheels,
which is approx115-120 at the flywheel; RX8 based engines are expected to show a 10% increase on these figures with better BSFC due to improved port design.
An RX8 single is due to be dynoed in a week ot two. BR, Dave McCandless,  daval@iprimus .com.au
