The tooling is ready to go for the first sample castings. The first 20, or so, go to Snyder. They will be available in iron also.

Wow, even after watching youtube videos to see how things are cast in metal it never ceases to amaze me. Keep up the good work Tod.

That amazing. I would love to see a picture of how they look once installed...even better, a video of one running.

Can I assume these are also high-compression?

Back in July 2002 Secrets of speed magazine had a piece on using a 82-84 Datsun / Nissan dual plug ,dual coil four cylinder distributor.........could be an option ?

I'm not sure. Snyder's sell these to the airplane guys. Pietenpol. I imagine it is available through someone.

Typical aircraft engines are required to have redundant systems (as backup). I would think they would use aircraft magnetos instead of distributors though.

If the aircraft is licenced as 'Experimental' by the FAA, redundant ignition may not be required (I'm not sure?), but it would be a good idea.
 
Nissan dual plug one the way to go , I run one on an 8 plug McDowell, Had a few stashed away for spares , I think it fires the intake side 1st then 12* later fires exhaust side, might have that around wrong way , simple to fit , Derek headed to AZ,

You are correct in your thinking, IMO and experience. I sold several Wico 1509 (up top of head) and several side mags for old aircraft usage.

What ignition system changes are necessary to fire twice the amount of spark plugs?

Hey Bob,
Differing ways to accomplish same goal. As mentioned, some more modern distributors (Nissan, etc) are used.
Another way Is to use Charlie Yapp front timing cover 'stock' looking 4 cyl distributor..up front, and to also use a mag or another 4 cyl dist up top.
 
Very nice! My Dad built a Pietenpol back in the 60s (used a Continental A-65) I still have the plans and thought of building one someday. Car engines in aircraft scare me a bit but this would help.
