    Default Ignition box for blown engine

    Which ignition box do you guys recommend for a blown pump gas 548 ci Chevy. I run 11/12 psi of boost. I have been told the blower will blow the spark out if using a MSD 6A/6AL.

    Daytona Sensors.

    My personal thought would be that a 6 MSD would do fine, but I don't know. I run an MSD 7 using about that same boost with no problem for e85 and did the same with AV gas.

    Where can the Daytona box be purchased . Do you agree with what I said about blowing the spark out Scott ? I don't detect a miss with the 6A.

    I've ran a MSD 6AL on a smaller(469 blown jet deal with 10 lbs. for 8 years with no issues.

    Straub sells the Daytona Sensors but that's not why I recommend them. We sell MSD as well but IMO the DS is a much better ignition. I think the MSD would work, I'm just not a fan. Too many failures.

    That was 2 owners ago. Much has changed. The old stuff is the good stuff.

    I have old MSD 7al boxes... if I did not...
    I would jump on the Daytona sensor piece in a minute. FOR ME.
    I won't tell a guy to buy a new MSD.
    A blown gas piece WON'T blow out the spark. Idiotic internet bullshit.
    BUT...Daytona sensors has tons of advantages... I WILL be buying one for the dyno ignition.

    What about 30 psi with a centrifugal blower? Will the DS support that?

    Scott , will the Daytona work with the MSD Coil ? I've got a MSD ML3 box I'm thinking of replacing down the road but then I guess I can't use the MSD plug in style modules etc ??

    I'm pretty sure the answer to that is no, and no on the modules.

    I am running a MSD7 with #10 boost on methanol and I have never detected any misfires. And never any failures Im very happy with it.

    Thanks for the reply Scott. The guy that I got this Vortech V4Z system from said he had a problem with ignition when he was running the higher boost. And he was running an MSD ignition system..... (dont know which one) and at 10# boost it was ok, but when he bumped it to the 30# boost pulley it had trouble with ignition.

    So before I go buy MSD stuff and waste time, would I be better off just going with the DS system? Is it just the CD box or do they have a disty, coil and everything? Is it comparable in cost or much more $$$?
