See Bill, Aren't you glad you took Mr. Wizard's Class!
 Think he knows how to lay out historically correct '69 Trans Am Stripes?

They always leave some important word out of advertising and that word is potential.
It has the potential to hit the advertised voltage but probably never will. Several issues dictate this. Few of them being plug gap, rotor to cap gap, cylinder pressure of the engine at the time of ignition. Would there be a difference in performance between a 50k volt and 75k volt on a stock engine? Not likely. Same idea that if you upgraded your 35 amp Motorola alternator to a 200 amp unit and the only option you have in your car is the Motorola transistor radio. It's not going to release any more amperage than the original since power demand never changed.. |

It's all kind of based on your equipment and your needs. It's like an 850 carb without a cam. Like a big cam without headwork. Like Headers with a single exhaust. Like 800 watt amps powering a cassette player with Wal Mart "Loss Leader" speakers! Choose wisely specifically for your needs. Sometimes overkill can be a dissappointment.
Based on testing, I would say I could see improvement with the Ignitor III with the full 12 volts, higher compression, plug gap change, plug wire change, and other parameters to maximize what is installed. It's why Drag Racers do the things that they do! Edited by TorqueyAMX - May/03/2009 at 10:51pm |

But the bottom line is having too much charge from the coil is not a bad thing whereas having too little charge is not a good thing. So if you have too much who cares. It sure beats not having enough.

But the folks with street or street/strip engines worry about not producing 150,000,000,000 volts and how their car won't start well enough and all that CRAP.
I'm trying to get some FACTS out there, the hi-perf folks have everyone running scared with marketing hype for high-performance ignition junk, I'm trying to prove and explain why most folks don't need a $300 ignition system, it simply is NOT needed.
And as far as too much - fine, but why? If their engine does require so much spark, then they have other SERIOUS problems. I'd rather not mix hype and mis-information with plain fact.
That's the reason for telling folks like it is.
Yeah, Torquey - the drag racers are pulling much higher RPM - very hard to saturate a coil at those speeds.
Now you wanna talk stereo equipment - we can do that, too! I used to compete in the Alpine car audio contests.............. never did better than 2nd, mostly 3rd place, but not bad on my farmer income level of, well, annual losses! LOL. I was competing with some high-dollar stuff.
It's amazing what you end up hearing from your favorite bands when your system has the power to properly and faithfully reproduce it. Too much speaker and you under-drive them. Too little speaker, too much amp, you over-drive them, distortion up the wazoo. There's a system that needs to be balanced.
Anyway, I'd love to see one of those new ignition systems first-hand - that's probably the direction I'll eventually go, when I get the Eagle parts paid for.................... Edited by billd - May/04/2009 at 7:00am |

I am sure you realize that I was not talking about 150,000,000,000 just suggesting that if it exceeds what is needed for a given application it won't hurt anything but if it is below what is needed it can cause problems. Likewise with the alternator example, having a 100 amp alternator won't hurt anything. Agreed that the excess may not be used but it also is not an issue if you have that extra capacity and never use it.

Yeah Bill but a good system still won't make Brittany Spears sound any better!

After a long talk with the head electronics guy at Pertronix, I thought I'd update this thread both on this end and at the front end as I learn more about this brand new Ignitor III system and how it compares to other types. I'll keep it simple where novices can grasp the concept along with technoids. This is what I've learned so far. I've also updated the beginning of this post with this new information so if you've already read this, never mind!
If you check out their website, you will see various features listed for each system. For the Ignitor II and Ignitor III units, you will see, "Adaptive Dwell"
Ignitor II and Ignitor III utilize adaptive dwell. These micro controlled ignition systems maximize spark energy a different way than the HEI's. The newer Ignitors samples coil current levels just prior to spark, and uses that information to make adjustments to the dwell time in order to reach peak current levels. At low rpm when the actual time between sparks is greater, the dwell is started much later in the cycle to reduce system heat. At higher RPM's when the time between spark is short, the dwell is started earlier. The Ignitor II and III systems adapt to most any coil and attempt to reach maximum current by adjusting the dwell angle. High Performance low resistance coils are a must for Ignitor II and III.

Could have been worse! Could have used "Mrs. Miller" from the Ed Sullivan days if you remember her!
