    I am converting my Roto-Faze from dual points to dual Hall effect triggers.
    I am looking for some ignition technical advise on phasing between the two triggers and the effect on dwell with the magnetic triggers.
    I know that the two triggers must be set at 45 degrees apart . The magnet is from a 4 cylinder 4 magnet ring. All dual coil distributors have 4 lobes and two sets of points. No cross firing and 60 degrees of dwell with points. Huge spark while both coils work 1/2 as hard alternating from left to right. Kong Jackson’s Roto Faze is a work of art and a mechanical marvel and is one of my prized pieces of speed equipment on my car.
    My question is if I mount each trigger dead center along an exact 45 degrees angle to each other starting with no. 1 cylinder trigger leading will the dwell for coil saturation be exactly the same for both? With the points I set each at 60-62 degrees of dwell and it hauled ass.
    Air gap will be set at .030 and I can only assume the dwell of each will match once its set on a Sun dist.[​IMG][​IMG][​IMG][​IMG][​IMG]Machine.[​IMG][​IMG]

  2. If you are using pertronix a the dwell is handled by the unit. I’d think you would just have to set 45 degrees apart and check in a machine proper phasing. Might have to verify rotor phasing as well to make sure it fires when the rotor is in the right spot in the cap

  3. @quicksilverart46 ... did you figure it out ?

    You can always call Joe Panek at RotoFaze. Still kickin' .. of course.
