Paul,

I was reading Tracy's updates for the renesis where he had bolted on the

new RD-1C drive with 2.85 ratio to the old 13B.  There was mention by Finn
Lassen saying "Guess Paul Lamar was right all the

time about the higher ratio being the best choice".
This was before my sign up.  Could you recap your comments re this

matter please?  Thanks

Tony Beaton.

I realized right from the beginning we would never have the power we could

have if

we limited the RPM to 6000 by using only a 2.17:1 gear ratio.

A similar situation is occurring right now with P-port verses side port.
If we are ever going to impress the aviation community with the rotary we

need

a better power to weight ratio than the current air cooled aircraft

engine.

As it is now with side ports the rotary is just about parity. With P-ports
the engine will easily generate 250 HP and weigh what a current 200 HP IO

360 weighs

namely right around 300 pounds. 250 HP Lyc O 540 and Cont. IO 470 weigh

about

420 pounds.

The rotary engine shows no signs of ever wearing out at the current 200 HP

level.

Until we see evidence of that we are not taking full advantage of the

rotary engine.

What's the weight of  the I0 - 360.

Hard to nail down exactly but it is around 300 pounds.

The basic dry weight of an IO-360-A2, as listed in the Lycoming web site, is
293 lb.  According to my information, the actual weight is 326 lb, including
alternator and mechanical fuel pump.  However, I am unsure whether this
number includes the starter assembly or not.
