Hi

i am currently building a mustang 2 and looking for a
turbo engine in the 200 to 210 hp range

i am hesitating beetween a subaru 2.2 to 2.5 with
after market turbo and racing type computer and fuel
management

and

the rotary with after market turbo

from the research i did ,power wise both are up there
no problem but reliability wise i keep earing comment
about oil leak and seal problem on the rotary

i agree that the rotary reduce frontal area is a plus
as is well as his basic working principal

so what to make of this comment , are they bla bla
from poorly maintain engine owner or some real consern

where could i find reliable information about the
rotary engine , from engine selection to intaled
weight

thank you

Oil leaks vary by builder. That applies to any engine. If you are
referring to apex seals that problems was solved in the late 60's.

Go to OSH and ask the man that own one. Rotaries fly in from all
over the country to air shows like OSH and Sun & Fun year in and year
out. I don't see that with airplanes powered by Subaru's.
My guess is a high power soob is good for 300 hours or so. At Sun & Fun Soob's are
frequently missing altogether on auto engine row while there are four or more
rotaries. Same goes for OSH but OSH is less organized getting all auto
engines together so I am not sure if there is not one lurking out there
somewhere. Sure you see them in commercial booths of people hyping them.
I would say a Soob would make a pretty good 100 HP aircraft engine but
pumping it up to 200 HP is dicey. Finally you don't need a turbo to
get 200 HP out of rotary. BTW read some of the text on the web site below.

Hi Claude-

Birds of a feather, as they say. We also are building a Mustang II, and we started thinging Soob first, before going rotary. Finally, we also started
turbo-rotary before ending up a NA/PP rotary where we are now.

Feel free to contact us off-list & we can share MII war stories...
