    I am new to the blown hemi stuff, what is everyone using for crank triggers and wheels? We are getting pretty close and just need a little help!
    Thanks

    There are two major trigger sensors available that both work great made by MSD and Leahy (http://www.electrimotion.com/). MSD's comes with the wheel but with Leahy's youwould have to get a wheel from RCD. They are both good. The BIG thing to make sure about is that both crank triggers have shielded and grounded cables. If they are not shielded and the shielding grounded then strau Electromagnetic Interference from the high voltage side of the ProMag will randomly fire the system and may destroy your motor.

    Crank trigger

    I use a RCD hub and wheel. also Leahey Trigger with a RCD bracket. I beleave MSD makes a small pick-up as well.You will need some lead time when ordering from Leahey. He makes them the way you need. as straight. 45/90 degree also length. Just try and keep it as short as you can. and still make it work. What ever you do, buy a new pick-up. They can be a pain sometimes. Don

    got customers using rcd wheels ..and even using the msd universal 8655 cranktrigger kit..
    they machine the center and holes to fit on the crank hub, also depends on the room you have... 3/8 or the 3/4 pickups...

    Just bought one. Construction looks really good. It came with the switch and harness to change from mag to trigger, and shipped the day after I ordered it.
