    Max Boost on Stock Denso Coils?

    What is the most boost that anyone has successfully run on standard Denso Ignition coils? They only charge at about 1.8ms I am wondering if you will blow the flame out much over 20psi? If you increase the Dwell time you fry the ignitor circuit.

    I am not there yet, but if someone else has been, it would be useful information.

    You can close the plug gap up some to increase the threshold, but I have not tried yet.

    22-25psi with out cdi
    you can go to 30 but you will find as the coils worm up after say 6 laps cc racing,you will get missfire
    i run cdi with all my motec and autronic setups with stock coils
