    Default Mags

    Anyone want to talk about the pros and cons or should we wait for another day?

    Heard the guys with the "mag failures" actually had other issues. They just told you it was their mags to make you feel better. Just what I heard

    No! They both came in and changed transformers.Something else nocked them out of the race. The 22 went out with a broken prop, the 24 went out with a broken V drive. Went replaced the MSD with a mag(really I did) and it knocked us out. Truthfully, that was my fault, not the mags. The point is, 2 magas failed at the enduro. A few more thru the season as well. We never lost an MSD during the season.

    We lost a transformer at Burley. Mallory Mag V w/ 28900 transformer. The problem was a bad plug wire ( loose end from MSD ) .

    They act like a HEI, if it can't send the spark to the plugs, it backs up into the ign system ?

    OH but it did. It would probably lasted all day on the MSDs. It was the same motor we have run for the past 2 seasons. But it so bad now I am actually afraid to look at it right now. But I bet its bad. Like I said not the magfs fault but mine. Sent the boat out with the timing a mile off.

    Battery connection. Loose as hell. It would miss fire when it hit some rollers. Finally blew the fuses inside the MSD.

    I can think of something positive to say about mags that I've heard others say,
    "They're simple, they only have one wire"

    Back in the in the Offy days at Indy, they used 8 cylinder mags and grounded every other lead off the mag. If the didn't they would fry in no time.

    Default Magneto vs something else - not shocking news

    Sirs and others that might be interested in this stuff,

    Magnetos have been around a very long time and modern mags are better than old stuff but many things still remain the same. They are typically limited in the amount of spark energy available.

    A typical magneto fires 4 plugs in positive polarity and 4 plugs in negative polarity. Without beating that pony to death not all plugs get the same level of spark energy (4 are down about 25+%) from the git-go. Just the nature of the the magneto critter.

    IF you have to have a battery on board anyway and IF you have the courage to run an alternator (for distance events) then running a modern type CD (capacitive discharge) ignition is much more forgiving than the lower spark energy levels of a magneto.

    There is much more that could be compared in an A vs B outline format, but it takes too much effort to do so.....

    For blown fuel applications, the MSD mags are probably superior.

    For almost anything else, I highly recommend MSD ignition stuff for the electrical energy at the plugs.

    Regards to All,
    IG
