Subject: [FlyRotary] Re: Whats good for
Racing is necessarily good for aircraft was Re: Intake questions
This may be just side commentary and a useless
data point, but for what it's worth here is another somewhat different
comparison. Also I've copied Jon Lauter on this because he must have some more
knowledgeable input. I have one of Jon's Rotary Power Marine engines in
a boat. (Cut that laughter right now). He rated it at 175hp and has a short
manifold to a carb just above it on the intake side of the engine (also
distributer ignition, turbo block and rotors).
My "dyno" comparison is with the previous engine
a 150hp johnson outboard (Will you guys cut that out?) The current
installation must be well over 100lbs heavier due to the conversion from an
outboard to a stern drive but turning only 4500 I'm the same speed as the 150
hp so I feel pretty comfortable that should I let this get up to 6500 I'd have
that 175. Pretty scientific, I know.
Hopefully Jon will respond.
By the way, it is really nice cooling a boat
engine!

Peter, just the guy I want to talk too. I'm
converting a 4.3L Chevy stern drive boat to rotary power so I'm curious about
what you used to interface the 13B to the stern drive. I figure I'll be
droping about 150 pounds.
I have assumed that RPM is doing jet drive
boats but maybe they have stern drive stuff too? I seem to have lost
Jon's email address so would appreciate it if you could pass that
along.
BTW, I used to fly a 135 HP Johnson
outboard. Now *you* stop laughing : )
