Looking for a high powered ignition system? The IGN-1A Race Coil is designed to put out 103 mJ per spark, with a longer spark duration (2.9 ms) than what you’d see with a capacitive discharge. They are the same coils used in the Huber Mustang, which makes over 250 hp per cylinder, as well as on our own land speed record holding LSR 240sx.
IGN-1A Race Coils have a 19 amp IGBT ignitor is built in and can be driven with a 5 volt logic level output – an MS3X or MS3-Pro will run them directly (set spark output to going high), and we recommend a 270 to 330 ohm pullup if you’re building a MegaSquirt 1 or MegaSquirt 2 to drive them and can fully charge with as low as 2.5 ms of dwell. Normally, you’d use them for a distributorless ignition as a coil per plug application, however they can be fired sequentially or every crank revolution (wasted spark coil per plug). If used as a single coil with a distributor, you may need to run a bit less dwell to prevent heat buildup from being an issue. Maximum recommended duty cycle is 40%.
Plugs are sold separately. We offer either a 2′ long flying lead pigtail or a pin and connector kit.
Here is the connector pinout:
A – Ignition signal from ECU
B – Logic ground, connect to ECU ground
C – Spark wire ground, connect to cylinder head
D – Power ground, connect to battery negative
E – 12 volt power
The coil dwell starts when a 5 volt signal is applied to pin A and the coil fires when the voltage drops to zero. The signal is similar to an LSx coil, although it does need a bit more current to trigger.
Coil specs:
Minimum voltage output (no load, at recommended dwell): 40,000 volts
Output energy: 103 mJ
Spark duration: 2.9 ms
Primary resistance: 0.5 ohms (not directly measurable)
Primary inductance: 4.8 mH (not directly measurable)
Secondary resistance: 8,500 ohms
Secondary inductance: 22.5 H
Turns ratio: 71.1
Maximum current: 19 amps
Maximum battery voltage: 17 volts
Nominal dwell: 3.0 ms
IGN-1A Race Coils are very solid, robust coils that will do well for you if dwell is set up correctly. Excessive dwell or duty cycle may cause meltdown. As with any race coil, the manufacturer does not provide a warranty.
