Mmmmm show me the data?Steve Arndt wrote:...
The IGN1 is the most powerful coil available.

I have a set of LS2 truck coils sitting here...
Beyond a certain point it's like nuking rubble.
Secondary current is usually the criteria, as voltage is always "as needed".
IGN1:
Primary Resistance: 0.5 Ω +/- 10%
Primary Inductance: 4.8 mH +/- 15%
Secondary Resistance: 8.5 kΩ +/- 20%
Secondary Inductance: 22.5 H +/- 20%
Output (50pF load): 41 kV +/- 10%
Output Energy: 118 mJ +/- 7%
Peak Secondary Current: 100 mA +/- 7%
Arc Duration: 3.2 mS +/- 10%
Turns Ratio 71:1
Maximum Battery Voltage: 17 Volts
Base Dwell: 3.0 mS
Max Continuous Dwell: 9 mS but don’t exceed 40% duty cycle
Max Intermittent Dwell: 80% duty cycle, 5 seconds maximum
Mating Connector: Packard/Delphi 12162182 “Pull to Seat” Included
Mating Contacts: Packard/Delphi 12124075 “Pull to Seat” Included
High Tension Wire Terminal: HEI “spark plug top” Style
LS2 "truck coil" d585: (Sounds like a Wells part#)
Dwell protected at ~7ms @~13.8v.

"120mA secondary current
The dwell should be set at 5 milliseconds input pulse trigger - going longer
does not generate any more spark current.
To get 5.0 milliseconds of running dwell, the nominal dwell parameters should
be set to:
Maximum Dwell5.5 milliseconds
Maximum Spark Duration 2.0 milliseconds
Acceleration Compensation 0.5 milliseconds
Battery Voltage Compensation
Setting Net Voltage Dwell Compensation
-4.0 8.0 Volts 2.4 milliseconds
-2.0 10.0 Volts 0.9 milliseconds
0.0 12.0 Volts 0.0 milliseconds
2.0 14.0 Volts -0.5 milliseconds
4.0 16.0 Volts -0.9 milliseconds
This will give 5.5 - 0.5 = 5.0 milliseconds at 14.0 volts while running with the
alternator charging normally. "
