Whats the correct air gap on the crank trigger pick (Sensor)?
This is a common question that is affected by other outside sources like: Crank Trigger Wheel Diameter: (smaller vs. larger, larger being better because of higher magnet velocity) Starter Type: Block mounted vs. External (Blower Mounted) Battery voltage: 12 Volts -24 volts (block mounted) 36 – 48 Volts (External starters) Induction: Blown vs. Non-Blown (Blower more engine drag especially when re-stripped) All of the above will play a roll as to what the proper air gap will be for that engine combination. Typical air gap should be between .040 to .080 the low side is deemed by crank flex and high side is hard starting to no start. If the engine fires up repeatedly, that can ensure the air gap is correct, and crank flex has been accounted for. Air gap should not have a performance effect of the magneto system, however it has been noted that an excessive air gap can create a timing offset in the Race Pac data recorder by as much as 2ยบ depending on the air gap.
