To answer a question one would like to ask yes I use the Second Strike and have had no failures. I cannot say the same for anything MSD related since I have had many failures with MSD items. Since going complexly with Pertronix many years ago the failures have stoped. Ronnieroadster

Re: Pertronix Nightmare
Ronnie, thanks for that info,
this is on a customers car, and he had the msd street fire and a e fire distributor, the setup would only fire 5 cyls, I have found the fault and at least got it to run using the old MSD distributor from my dragsters that can't stay on the car, I never knew there was a u nit like you mentioned and will look that up. thanks |

Re: Pertronix Nightmare
Some times technology is a good thing especially when your running a modified combination. When the correct improved parts are used there's no trouble at all. Ronnieroadster

Re: Pertronix Nightmare
The stock ignition system works great on a stock engine - or almost any street build (depending on RPMs). If they're setup with high quality components, they will run up to the RPM limits that most hot-rodders on the street will hit.
When you start getting into much higher RPM builds, race engines, etc. - there are improved ignitions that can take the RPM, have high spark energy, etc.. I run mostly magnetos on most of my race style engines as well as the MSD ProGrid and a MSD distributor on some setups. I have not had issues with my MSD ignitions - other than one bad coil. I also run a MSD 20 Amp ProMag on one of my race engines (blown alcohol) and it makes a difference when you're trying to burn a lot of fuel under boost. |

Re: Pertronix Nightmare
I have had terrible issues with pertronix products. I gained 17 rear wheel HP going back to points on a big block Chevy in a Camaro. Sent ignitor back to pertronix and it tested fine. Most will work fine on a distributor tester, put them in an engine firing a plug and they won't hold steady timing. That variation in timing is costing you power.

Re: Pertronix Nightmare
Was that an "original recipe" Ignitor, or was it one of those fancy pants variable dwell & rev limited variants?
The Ignitor I is about as simple as it gets and the particular one I always recommend to people who just want to get away from points & condenser ignition for whatever reason. For racing stuff, well I dunno that's outta my wheelhouse. It's kind of interesting if you think about it - the Hall effect sensor is today about as far removed or obsolete as points were/are, compared to where electronics are today. Cadillac introduced contact points in 1910, the Hall sensor (via IC) about 1960. The disadvantages with a simple electronic "switch" (that's all a Hall effect sensor is) would be the same as ignition points or mechanical switching - a fixed dwell period that it is selected as a compromise. The same unit I bought in 1997 has worked fine for thousands of miles up till today. I know now points can be made to work fine obviously, but back then I didn't understand that, couldn't figure out that a loosey goosey junkbox worn out distributor will never hold the dwell, and on a Y-Block, the distributor is way back against the firewall. My back started to protest! And I fell for the "never change points again!" advertising. It would be interesting to see some dyno tests (or emissions) with the Ignitor I versus contact points in comparison, it would be tough for me to believe the electronic modules would perform any worse in that situation. |

Re: Pertronix Nightmare
Thanks for that link. That's about the coolest thing I've seen all day, though it's still early yet.

Re: Pertronix Nightmare
Pertronix has been beat to death several times on this forum (and on HAMB)......Most failures have been traced to improper installation/incompatible coils.
I have used the P-1 version for over 25 years on the 327/375 (Rochester FI) engine in my '40 coupe with zero issues. My reason for ditching the dual points was bounce and premature wear at high RPMs. My son's 302 SBC off-road Trans-America engine has used a P-II version since they were offered for sale, without any issues. It has a Corvette dual point fully mechanical distributor converted to Pertronix and functions very well up to 7500 RPM. I have found both versions to be very stable through the RPM range, and reliable. |

Re: Pertronix Nightmare
I think the 12 v guys with no problems probably have an alternator on the engine. My limited understanding is that the Pertronix systems don't like the voltage variance a generator puts out compared to an alternator. Maybe that issue has been addressed.

Having personally converted a lot of 6 volt distributers to Pertroxix I can say a generator will not cause a failure. Failures experienced are what others have written leave the ignition on with out starting, incorrect coil or ignition wires. The Pertronix system is so simple to use and extremely reliable and also responsible for incredibly fast speeds by many users. Ronnieroadster

Re: Pertronix Nightmare
This all seems to be coming back to an underlying issue that 1 instructions issued by the supplier are not specific enough in the cans and cants 2 people being people tend to think installation instructions are only the suppliers opinion 3 most of us dont under stand fully how some of these so call advances in technology actually work and their limitations also i havent heard of any supplier listing a complete kit [ignition unit any filters required coil and lead sets this would remove a large portion of what seems to be common errors
