Dual 50K volt test ignition

NOTE, Dan Sheradin put a link in the comments to a working 30 second video. I have issues with getting videos from my iPhone to directly work with the blog software.

Builders,

Not all tests are directly aimed at making a product next month, some are pure R&D to test ideas which may or may not be integrated into later products. Either way, the understanding which comes from afternoons like this is part of what makes my experience valuable to traditional homebuilders.

Above: On Sunday I let this test ignition run on my 1947 sun distributor machine for several hours. Get a look at that spark, it is arcing over a 3/4″ air gap. It performed flawlessly, but is it something useful? In spite of working great for hours, it would still have to pass three critical tests: Power consumption, elevated heat tolerance and low voltage ability.  My current E/P and E/P-X ignitions do, and they do it affordably.  Looking at a system like the one above, it has advantages, but they come with questions and a different price tag. These are the the things you consider while this hums away in the shop for several hours.

The Details:

Body: Corvair dual bushing

Cap adaptor: Ford V-6

Pickups : Chrysler slant 6

Reluctor: Hand made

Module A : Chevy V-6

Module B: 1981 Pontiac 301 turbo.

Coil : Echlin 1990s GM E style, ultra low resistance.

.

The wiring is spread out a lot to make it more accessible for testing, it facilitates putting the heat gun and thermal camera on individual elements to see how the perform under duress.  Yes, Vice grips have a place in the world of tests and evaluations.

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.

    Here is a link to William’s Dual 50K Volt Ignition video

    I’m posting this to prevent William from using his iHammer on his iphone and then using his ishovel to bury the remains.

    I would really be interested in installing one of these! While I religiously check and set timing at WOT, it does make me more than a little nervous! While a prop at 1000 rpm is just as deadly as one at 2900 rpm, the prop blast is a little more manageable at idle.

    Any thoughts when you might have this distributor available?

    Thanks
