High Output Coil

P4120889;sq box Supercoil. Been using it almost since day-1, in early 2000s. Goes to well past 7500, firing .045Plus gaps, through Jacobs wires(anybody remember him?) BTW my Champion Coppers have been in there since around 2004. They went in at .045. I have no idea what they are at today.I take 'em out now and then, when I check my compression; 10.7/1, or so. Maybe a tad more.
