Hello everyone i guess I will introduce myself. My name is Robert
    Sando.I
    live in Delaware. I am building a 4 place vision from
    www.visionaircraft.com. I initially was interested in using a Subaru
    conversion in my airplane because I thought the rotary wouldn't make
    200hp
    but after more reading I found out how much power can be made with a
    13b or a
    renesis. I thought that I understood the operation of the Wankel until
    looking at this animation. After careful study it looks to me like the
    combustion chamber is the depression in the rotor face. Is this true?

    Well to make 200 HP with a RX8 high power side port
    motor you need a 2.85:1 PSRU and it will be just 200 HP
    at around 7000 RPM. Your intake manifold must be just so.

    Don't fool around and be disappointed. You will be sure to
    get much more than 200 HP with a p-port RX8 motor or other
    Mazda rotary.

    Yes the combustion chamber is in the rotor face.

Robert, I thought the Vision spec'd in a 120 HP powerplant?

Paul, This rotor animation has a link (blue) from the shaft to the rotor
apex that goes "thru" the shaft at every revolution.  What am I looking
at here?

Yes and that is not the way it is. The trouble with the
eccentric animation is it is hard visualize the eccentric
moment arm where as this one shows it clearly.

Paul,
The Vision 2 place is optimum with 115 to 125 HP  with a Firewall
forward limit of 300 lbs - the 4 place is ?

Send me a picture so we know which Vision we are talking about.
