nklr direct hits and split fires and electrex

[Weaver, Mark]

geez, just go to their website and read the technical data. it's appears to be a peaking capacitor to give a shorter more powerful spark. i'm no engineer, but i'm reasonably educated, and with a degree in math (proving things), i can usually spot totally obvious b.s. i perused the website for a few mins, and decided i should ask my brother (a mechanical engineer who specializes in internal combustion and emissions issues) about how installing a peaking capacitor directly over the spark plug would affect the combustion process. i'll post to the group when i hear back from him. the tech article by the Sandia Labs guys makes it sound like using the non-resistor model spark plug is definitely going to give an improved spark as well (which someone else mentioned earlier on this thread). i accidentally bought a resistor plug a few months ago, but i'm ready to change it out now. i'll probably do that tonight based on what i've read today. mw p.s. while it's good to be skeptical about outrageous claims, it's also good to read and understand what's going on before outright dismissing them. the direct hits claims don't seem all that outrageous to me, and there may be some science behind them (at first glance), so i'll withhold judgement until i hear from a real expert, and the listers who've tried them can make a longer term report.

If we were still back at RPI, I'd
