Don't know if conventianal spark plug rules apply here... Looks good coz you get 100% spark exposure over a long distance, no need to indexFLORIT said:Wow, that's different. I wonder how you set the gap on THAT thing.
Plutonium wonder plugs made by elves in the forest... :gr_jest: :gr_jest: :gr_jest:mistermike said:No they're not cheap, but it's not everyone who can brag that their plugs are crafted in the Czech Republic. Actually, a lot of your contemporary "plutonium wonder plugs" made by elves in the forest are $10-14 a pop. What I find intriguing about these is that they're "auto indexing" which might explain why the blown Ford guys like them. Indexing starts to become an issue as cylinder pressures climb.
Not only would the plugs need to be absolutely concentric, the material concentration would need to be absolutely uniform - all that chaos theory crap.mistermike said:Yes, that's the take on auto-indexing. The guys running extreme drag engines will spend a lot of time pointing the gap of a conventional plug where it does the most good. I've done it on a few cars with mixed results, and it's a pain in the butt. Dr. Christopher Jacobs, a bona fide ignition guru, states "It may not always help, but it never hurts." I've tried the Boschs a couple of times. On one engine, it was a big plus, and on a different engine, it degraded performance noticeably. I suspect that the proclivity of the spark in the Brisk plug to favor an area of higher fuel concentration would be highly dependent on the electrodes being absolutely concentric. Their other claim that a spark drawn across a surface is easier to instigate than a spark across a pure gap is interesting. Our GTOs are supplied with Delco iridium plugs made by NGK. Plain old copper NGK TR55's idle smoother for me. Might be a different situation with forced induction. The big iridium fans seem to like the Denso's better.
Makes sense to me. Even Doc Jacobs, who is a PhD EE, and a lifelong drag racer states that there are several competing theories on why a spark even causes the fuel to ignite in the first place. Even an explaination of how an electrical discharge "knows" the path of least resistance conjures up some scary theories. Tachyons anyone? :eek2:phobos512 said:Not only would the plugs need to be absolutely concentric, the material concentration would need to be absolutely uniform - all that chaos theory crap.
