MSD Tech: Rotor Phasing

By: Ray Frescas | 08/01/2011 < Back to Motor Life Home
On engines with extreme cylinder pressures, such as nitrous and supercharged applications, correct rotor phasing increases in importance. More voltage is required to ionize the plug gap and if the phasing is off, the spark is more apt to find an easier path to ground rather than the correct cap terminal. This may result in severe engine damage. Check out the tech video to keep your phasing in check.
