    MSD 12, 20 or 44? Blown alcohol.

    I have a 12 now but its new have not run it yet? Should I get it upgraded to a 20? Sell it and buy a 44?

    what is everyone running and more importantly WHY?

    Go with a 44, we ran a 12 on our big block chevy with a 8-71 and was putting the spark out at 1000 ft . We put a 44 on it and no more problem, car picked up 2 tenths,. we now have BAE and I would not even try anything but a 44.

    did the same thing as you. Called Snyder motorsports Larry told me to up grade to a 20amp set it out to Dave Leahy and got it upgraded to a 20amp could not be happier. Call Dave and ask him he will get you the info you need to decide on the 20amp or the 44 Vinnie

    have racers been having issues with 12's converted to 20's?
    and if so what were they?
