Bobby,
I did some maths on my single configuration and
that compares well to Powersports figures and we both agree that 44mm is the
optimum PP diameter.
My figures are 240hp (approx) at 7500 rpm - a
bit higher with the renesis 10:1 rotors. So
I'm looking for between 115hp and 125 hp with a take-off rpm of 7200
rpm. IMHO the PP is well worth
consideration if power levels are borderline, as in my case with the single
with weight considerations.
One of the chaps who was involved in Powerspart
was on the other list and gave some great insight into their development
work and their very small and light development of a 2 rotor which came out
to a similar weight to an Al housing development - beautiful little engine.
They used chrome molly (oven brazed) centre and end housings with a 12A
crank - lovely work. I have a photo if anyone is interested. One thing about
PL's site, the people drawn to it and a wealth of input, but not necessarily
PL's.
Like Ed, I look forward to the 16X - perhaps a
16X single, if the power is right.
