Im thinking it would be worthwhile to try to duplicate that if possible. So is there a better VB921/similar that is capable of 9+ amps? Or....
Can I use a pair of VB921s to drive each coil, and wire the VBs up as if I was doing wasted COP? That is, two VBs, 680 ohm resistors running off each spark output, but instead of four coils for four VBs, have two coils for four VBs? I would then scope out dwell in the standard way with both VBs going through a single 0.1 ohm resistor to ground.
That should prevent each one from going into current overload, and let me charge the coils to their full potential. Is there a downside to this that im not thinking of?
And heres a pic of the coilpacks in action. I accidentally knocked one of the copper wires away and saw that it could do this, so I took both of them off and took a pic. Yes I know spark length isnt a real measure, but this is a d*** cool pic and goes well with the DANGER HIGH VOLTAGE sticker on the coilpacks
