I am new to this site and I would like to know more about rotary engines, specially hp and weight ratio vs. piston engines.

Bare weight is under 200 pounds less gear box. Firewall forward about 320 pounds.
HP is 150 to 180 HP NA at 6000 RPM with a 2.17:1 gear box depending on how well the
engine is ported. 180 to 210 HP NA with a 2.85:1 gear box at 7100 RPM.
HP with a turbo is almost anything up to 800 HP you want it to be.

Hi, Paul.

Tks for your quick answer, which prompts more questions.

Tks for your kindnest in helping me.

1.Weight mentioned by you is for a two rotor engine?

Yes.

2. If so, what about the weight/hp for a one rotor engine firewall forward?

Good question. Several are building one rotor engines but none are flying
right at the moment.

3. Weights of turbo for one and two rotor engines?

Tks !

Ramón

Turbo's run about 35 pounds but some of that is offset by no need for
a muffler.
