MSD vs Atp flame total loss????

[easyrhino]

Sweet six cylinder setup.

Now post a diagram for a twin cylinder Superjet.
Did you notice how each individual coil on your diagram serves two spark plugs in parallel?

i may not be the smartest man jenny, but i do knowwhat a TL diagram is. How is the energy to the coils different when talking about the stock system vs what the flame sends to the oem coils? i am asking because i want to know.

 

[easyrhino]

do you know for a fact that msd made less volts on the multi channel? or is it now just using more energy than is required to simply fire the plug. i think they use more power than required.

If the TL is using the OEM plug @ set to OEM gap and only firing one plug.

ah man, my brain is melting, happy 4:20. i am going to the garage for a bit.

It's not something to worry about unless you're buying a timing light. You want to get the t-light with a direction inductive pickup so it only flashs once per revolution. The volts to the plugs are A/C. lol it reverse polarity for each cylinder.

so if you run a tighter plug gap, it would require less power to spark but if you have more power than now needed and it gets sent anyways would it not create a stronger or more powerful spark? Msd says this about the gap:

Spark Plug GapWith a MSD Ignition you can run a wider spark plug gap than you would be able to with a stock ignition. The MSD Ignition has a higher voltage output and can jump the spark plug gap easier. As an example, if you normally would run a .028 inch gap on your spark plug with a stock ignition, you could run a .032-.034 inch gap with a MSD Ignition. There are variables that will affect the gap size: the higher the compression - the smaller the gap; the hotter the output of the ignition - the larger the gap, etc.

Power is watts, I was talk'n volts. When the system reaches enuff volts to arc the gap it complete the circute and the secondary winding is short. But I think what you saying is true.

From http://www.strappe.com/plugs.html This is what I was talking about and we were using "Booster gap" with CDI. However, at bottom it says it's not needed with CDI fast raise time.

A final variation on the basic spark plug theme you should know about is something NGK calls a "booster gap," and is known at Champion as an "auxiliary gap." By any name it's an air gap built into a plug's core, and it improves resistance to fouling. Conductor deposits on a plug's insulator nose tend to bleed off the spark coil's electrical potential as it is trying to build itself up to spark-level strength. If so much energy is shunted in this way that firing does not occur we say the plug is "fouled." It is possible to clear a lightly fouled plug by holding the spark lead slightly away from the plug terminal and forcing the spark to jump across an air gap. The air gap works like a switch, keeping plug and coil disconnected until the ignition system's output voltage rises high enough and is backed by enough energy to fire the plug even though some of the zap is shunted by the fouling deposits. Mechanics discovered this trick; plug makers have incorporated it into some of the plugs they sell, and booster/auxiliary gap plugs work really well in bikes with an ignition system strong enough to cope with the added resistance. Such plugs more or less mimic the fast-voltage-rise characteristics of CDI systems - and offer no advantage used in conjunction with a capacitor-discharge ignition.

Msd says this about the gap:

Interresting.

Hotter ignitions also need better insulation on the high tension side. Its easier to have salt water gremlins if everything is less than perfect. I wonder if those $50 model airplane ignitions will work on a ski.

Interesting info guys. but we are still not at page 9 on my screen.

Any Updates?
