I had the Crane ignition with no problems but during my latest restoration I decided to go with Petronix. I only had about 7oo miles on the Crane but decided to go with the Petronix because I wanted it more simple and clean under the hood (didnt like the box and extra wires). I autocross with rpm up close to 6000, have I made a mistake going with Pertronix-----I know, "if its not broke dont fix it", but I wanted to go more simple. opinions please (will not go back to points, thats not an option for me.)
Well, what mistake? I think the ultimate test of a Pertronix is in a really Hot V8 engine bay of a Triumph Stag with a tuned Rover 3.5. My Pertronix has not skipped a beat (touch wood) in 4 years of very hot summer drives, including baking in 120 degree F traffic in Dallas / Ft. Worth last year at VTR 2006, temp gauge at 235 F.
My 3.5 ECU rev limiter is set at 7000 RPM and it has been there a few times.
IIRC the Pertronix units are good to over 15000 RPM, so that is much higher than you will ever dream seeing.
The first Pertronix units were polarity sensitive, so if you reversed the wires you could - not necessarily "did" damage the unit. I believe that those units that "failed" were reversed polarity my mistake of the installer. Also there have been some issues people have complained about with the magnets on the collar shifting or falling out under heat. I have not experienced any problems with the magnets dropping or shifting and the magnets are pointing down on a large disk in my Dizzy - an AC Delco unit. /bcforum/images/%%GRAEMLIN_URL%%/thumbsup.gif
