make an adjustable rev limiter for an MSD 6AL
 

tired of buying pills so after a bit of research I made this. I used a propane torch to melt the plastic and solder off the pill studs. then soldered them to a potentiometer ( ? ) I had. I checked the resistance on this chart

and my range was from about 1000 rpm to 6900 rpm. perfect! plug the pins into the pill holes and you're done. I'll come up with a better mounting solution but for now, it works! I might run the wires into the cabin so I could adjust the rev limit from the seat but don't see much need for it. I might do it as an anti-theft. with the dial turned all the way back it rev limits to about 1100 rpm. should annoy a car thief.
