What is MSD , and what will I benefit by using it ? I see some of the guys winning at my pulls are using it and I would like to know what it does and why?

Thanks ..

They work great for a high RPM application,Most tractor pulling is a low RPM operation,I have used them,I have notice no big difference on my tractors over a good pointless ignition and the correct coil.

i run an msd on my m farmall. a hotter spark does boost performance, i can tell a huge difference when i went from even a new ignition system to msd.

from what I understand MSD to be, it causes the spark plugs to spark multiple (3?) times every time instead of just once/revoultuion. I think that I read in the litature that it does this at 2000RPM and below. I use a MSD box on one of my pullers as a rev limiter, just change an external chip to change RPM's.

To get the hotter spark, use a hotter coil. I use a 40-50000 volt coil on my 400 with the gap on plugs at 45 thousands. Nice, bright huge spark.

The fellow who posted earlier is right, you don't gain alot by using the electronic iginition if your origional is in good condition. Mine was almost 50 years old!

MSD is a company that makes ignition systems, primarily electronic ignition. With hotter spark you can gap your plugs a little more. Electronic ignition is more reliable than point systems. ELECTRONIC IGNITION DOES NOT however boost performance vs a well tuned point system. You do not need electronic ignition to win. I use a system made by Pertronix, but that is because I got sick of replacing points and condensers.

Are you sure a hotter spark doesn't boost performance? Last I knew a better complete combustion makes more power and performance but I gues everybody has there own theories!!!!

You are missing the point , MSD or electronics don't make the spark hotter , the coil is the only thing that can do that. These are triggering units only. The hot coils and wires and good plugs are the performance enhancers.

MSD told me that a 6AL box, sends 450-480 volts to a 12 volt coil to amplify the coil output, so it can boost the coils output,,, but how long would your average everyday coil last at that kind of voltage? Chad
