Spark plugs; Fact or Fiction

Saw this on another site, looks to good to be true (40:1 A/F???) but I'm sure there are people here better qualified to make that asessment than I am.

Interesting reading. He may be an expert on spark plugs, but his understanding of his magic plugs raising the red line on the tachometer is way off base. I think that is a valve spring issue, not a combustion issue and most motor men will agree. Also, his thoughts on detonation being caused by unburned fuel/air may be a little suspect. Glowing carbon build up or a glowing thin metal surface in the combustion chamber can cause the early firing of the fuel/air early in the compression stroke. Since combustion chambers have not been changed (optimized) for the much leaner mixture, then you must reduce the amount of fuel drastically to get a 40 to 1 A/F ratio since the amount of air stays near the same. Dramatically reducing the lubricating and cooling effect of fuel in our present I/C design is going to produce some bad results, in my opinion. Thus, I will vote that this may well be more "snake oil" than fact.

What a bunch of hoooey. Surface gap plugs were installed in WWII aircraft for gods sake! Heck they came factory installed in late 80's Mazda 13B rotary engines!

Pseudo science that he can't explain, yea rrrrrrrrrrrrrrrright. Notice no independant 3rd party dyno charts to substantiate his claims, next snake oil salesman please.

Here is all you need to know..."STANLEY: How does that happen?

KRUPA: I'm not sure."

The plug is interesting and it might get a better spark, but some of the things he said just seem to be way off. A 40:1 air/fuel ratio just doesnt seem like it would work and not to mention it would make a unhappy engine. If they come out I might pick up a set to try them, but it seems like more of a gimmic.
