I am researching, looking for a suitable Rotary engine for an aircraft.
I would like to subscribe to your newsletter and also ask if you know
of a mfg. that makes a rotary engine that weighs 80-100 lbs and delivers
150+ hp to a propeller turning 2500 rpm.

Thanks

You have set HP per pound  requirement unrealistically high.
Is that the bare engine weight with out gear box or the firewall forward weight?
Wankel rotary engines usually run about .7 HP per pound firewall forward.

With a 3:1 gear box, all aluminum construction and and about 8000 RPM takeoff you might achieve as much as 1.2 HP per pound.

Small aircraft piston engines like the O-200 are .5 HP per pound,
The O-320 is about the same ratio.
