How does
the flying weight compare on the 20B with a lyco 360 for
example?
Thanks,
Bob

Re: Newby 20B questions
Dwayne,
I’m putting a N/A 20B
in a Lancair ES, so I’ll attempt to answer your questions. My engine has
a mild street port, so I’m expecting 275-300hp. Al G. had his N/A 20B
dyno’d at 275hp, if memory serves me correctly. So, that should be a
conservative number.
Advantages of a
turbo… more hp at all altitudes. Quieter exhaust, in fact you will
likely not need a muffler if you use a turbo. This offsets some of the
additional weight penalty that comes with a
turbo.
Disadvantages of a
turbo… more complexity (tubo, intercooler, additional plumbing), more likely
to detonate, higher fuel burn, to name a few. Also, you will be a bit of
a trail blazer when it comes to picking which turbo to use. The only
other turbo 20B that I’m aware is Tom Parkes in AZ.
My feeling on the
turbo issue to go with a peripheral-port instead. PP is simpler,
lighter, easier to fabricate a manifold, etc.
No, Renesis parts
won’t work. One of the 20B’s side housings in unique to the 20B.
This part is only available for the 20B.
Good
luck,
Mark

questions
Greetings
all,
First time posting
here so I’ve got a couple of newby questions.
1)
Does anyone know what
HP to expect out of a 20B?
2)
Can someone explain
the advantages / disadvantages to adding turbo to a
20B?
3)
Can a 3 rotor engine
be built using Renesis components?
Feel free to answer
any and all and thanks very much for your time!
Dwayne
