The magneto drive looks expensive. I would think triggering a bunch
of MSD ignitions off the e-shaft or flywheel would be less costly,

weigh

less and

might work much better than an aircraft mag. What is happening in the
states is most of the experimental aircraft guys are switching to

solid

state ignition systems. My next door hangar neighbor Klause of LSE is
making most of them.

I really got excited when I saw this.
I spent 16 years drag racing blown cars.
Looks like a 3:71  overdriven from what I can see.
And yes, Paul I believe you are correct in the MSD concept.
I converted an O-200 with dual msd's with crank trigger, and
the cost was around $1100.

Hi Paul
Unfortunately, MSD and all CD type ignitions are unsuitable for high
compression
drag engines running alcohol - the long duration spark of a magneto is
required.
Archie - the blower is an 8/71 Littlefield alcohol blower with teflon
strips, running
3% under.

MSD means multiple spark. At high RPM it is still firing several times
per combustion event. Able Ibarra here in So Cal claims 400 HP per
rotor on alcohol and NOS on both his two rotor and his three rotor turbo's
using MSD's. Jim Mederer claims about 1000 HP on aviation fuel
on his turbo 3 rotor using MSD's.
