Sonic spark plugs
Alright folks, this is an interesting modification to spark plugs.
http://www.enginebrain.com/ They use OEM spec plugs and drill a small hole in the ground strap to create an ultra-sonic wave in the air/fuel mix. The discussion on the web-site is interesting reading. On our A4, I have made changes that have made the engine purr, especially the temperature control valve and heat exchanger that keeps it steady at 180*. And the prop (10x7) that gives us a comfortable 1800 RPM and 5.5kts cruise speed (GPS). I'm curious to hear feedback on the science of these spark plugs. |

Both web sites show some random and nonlinear writing.
Not much makes sense to me, Just a lot of what may be cleaver thinking but not presented as understandable.

I think your time would be better spent building a tuned intake and airbox... Maybe look into a keihin fuel injection system, mapping would be easy since you would always be at sea level. Plugs, not so much..

He was able to get a patent on the invention - interesting...not very expensive either.

Ionizing
There was a big deal raised in the mid 70's with the same ideology. It was a series of induction coils "wired in series" and connected to the plugs and the plug wire plugged into the coil(s). There were all kinds of claims as to better millage and increased performance and of course it was recommended that you replace the plugs and do an "archaic" tune up IE replacing the points and setting the timing~sound familiar? The increase in millage and performance was due to the tune up mostly.
A reputable shop I won't mention that I was associated with had an employee (hi end engine builder) tell the guys that it really did make a difference. His BIL installed a set in an old something and he found that his partially fouled plugs did run cleaner. Well that shop set up a dyno and began testing some older engines and it did seem to help a bit. They did not find any gains but did find that the plugs seemed cleaner. So they set up a BB Chevy 7K RPM engine with a Mallory "rev-pole" style dual point distributor~top of the line at the time and started testing. They could find no gains but indeed the plugs did stay cleaner again. So they decided to make there own "ionizing system " only making there own more powerful coils and as testing continued again no gains but the very slightly cleaner plug. After 4 or 5 sets of ionizing coils and still being intrigued a much hotter coil was tried. At around 6,000 RPM's under a big load of probably 700 HP the engine burped and big parts of the crank and a few rods and pistons exited the engine through the pan and crank galley in a hurry. A total loss!! What happened was that enough induction built up so the "ionizing" coils actually created a series of sparks that were not part of the "timing" and sparks flew with the pistons in various positions, that was the shudder during the "burp" and the end of a very nice engine. Those devices were around for about 3 maybe 4 years. These plugs may indeed ionioze slightly or it is just the hole starting a "larger" and somewhat warmer area around the tip of the plug and this would only be effective at idle and very low RPM's, kinda like an increase in "gap".

Just get an MSD ignition box. You'll get several sparks at 3,000 RPM and below instead of one and "ionize" the crap out of your engine with no timing issues. One of my spring projects.

What happened with MSD anyway? There was a time that was high tech.
