In order to not overheat and damage to coil, the recommended ignition dwell at 9000 rpm is 2.8 milliseconds, 8000 rpm 3 milliseconds, and 7000 rpm 3.4 milliseconds. On the stock Evo 8/9 ecu the factory settings are completely safe for these coils to 9000 rpm. We run increased dwell times over factory depending on the engine's power level.
Specs on the coil are as followed:
- Output Voltage: up to 81kV +/- 10%
- Output Energy: up to 250mJ +/- 7% (8mS dwell @ 14 volts)
- Peak Secondary Current: 100mA +/- 7%
- Arc Duration: 3.2mS +/- 10% @ 3.0mS dwell target
- Max Continuous Dwell: 9mS not to exceed 40% duty cycle
- Max Intermittent Dwell: 88% duty cycle for 9 sec max
