How Hot Should My Ignition Coil Get

there is your problem... you need to run that coil using the stock hot wire. the stock coil i think is only 1.6 ohms, in order to run straight 12v thru a coil you need a 3 ohm coil.

let me ask you this. did you add wire to get direct 12v to the coil or bypass the ballast resistor?
