For dragsters and race cars running at over 7,000 rpm, a crank trigger system produces rock-solid spark timing.

A traditional distributor is fine for a street vehicle’s ignition, but high compression, forced induction, and big revs can play havoc with your timing. Any slack in the timing chain or lash in any of the gears can cause misfires or false triggers, and that can cost you a race.

A crank trigger features a wheel that attaches directly to the front of the harmonic balancer, and a sensor that reads the position of that wheel as it spins (the type of sensor varies by manufacturer). Since there’s no mechanical...

For dragsters and race cars running at over 7,000 rpm, a crank trigger system produces rock-solid spark timing.

A traditional distributor is fine for a street vehicle’s ignition, but high compression, forced induction, and big revs can play havoc with your timing. Any slack in the timing chain or lash in any of the gears can cause misfires or false triggers, and that can cost you a race.

A crank trigger features a wheel that attaches directly to the front of the harmonic balancer, and a sensor that reads the position of that wheel as it spins (the type of sensor varies by manufacturer). Since there’s no mechanical lag in transmitting the crankshaft’s rotation, timing remains perfect even at extreme speeds.

Timing adjustment can be made by moving the sensor; any centrifugal advance from the distributor is locked out. You can retain the distributor to drive you oil pump, or convert to a distributorless system.
