You brought it up and said I didn't have any (experience). I don't see why I shouldn't tell you mine.Originally Posted by stevedmc
I already said I'm sorry you were silly enough not to follow the directions.
I told you you were not on the same page...That is primary voltage! I have been talking about secondary voltage (relatively more coils in the secondary = more voltage output) and about voltage at the plug gap. You are putting words in my mouth (or thoughts in my head?), again. I've seen that idea here, but I didn't say it.
Good. You really haven't been doing that anyway...most of it was pick and poke instead...and the majority of the rest on some other page.

I was asked to do this, so here goes for the benefit of the doubt:
Take a deep breath, calm down, get on the same page and read this:
From the beginning, primary voltage...
Voltage (E) = Amperage(I) x Resistance(R), so R = E/I. At the moment before a spark, the resistance at the plug gap is a fixed value (it changes afterward but too involved to get into here), so, if we increase the primary's input voltage, the secondary's output voltage must increase. Now, (P)ower = I x E. Since we increased E and I (it will draw what it wants), we increase P. This is all you had to do to increase energy at the gap. You could of accomplish this by bypassing 1/2 or all of the resistor grid (that's what its job is!). Not a good idea...the rotor, especially one with a resistor in it, will not like it on a long trip (The more you run through them the more heat they give Sparky [oops FS, um,] off...); The change in energy changes the burn characteristics, including the moment of max burn (we want this to happen when the piston/crank is at the optimum position. [For those who wonder why timing is often set to a point before the position even reaches the top...That is basically why...the higher the RPM the sooner we have to start the burn...time]; The list goes on and on.
FWIW, I believe you (at least basically) knew most of this.

Now, the other page...the 'a plug with widened gap will not fire' - '"performance" includes HP and emissions' page.
I was, collectively, being told it is wrong to say increasing gap alone increases energy at the gap. And, that if we widen a gap, there would not be enough voltage to jump it.
That leaves us (me anyway) wondering how engines with wide/worn gaps run. [Bill said it won't. You didn't answer, even though the question was directed to you.] I see it like, we increase R by widening the gap and it still runs, so it must be sparking. So, we must have increased the energy. Now, we are back to P = I x E. We raised P, so...
As for "performance" includes HP and emissions, that was aimed at Bill, IIRC. Besides, he has repeatedly ignored the question from almost everyone since he knows most of ALL of the above (enough to be dangerous anyway) and that it contradicts his 'coil alone improves performance' statement(s) and his glorious paper (that is supposed to shed new light on 1981 technology (while it points to and agrees with a 1960s paper, and this particular point w/o question
...and wants me to argue with both of them (or should I say all three of you?)
of the Premier had AMC build plates on the driver's door, and even in 1989 the Premier an emissions decal under the hood that stated, "American Motors Corporation" and then in tiny letters, "Built by Chrysler." All models still had radiator hoses with the AMC logo.
