    I guess this is a dumb question, but i dont know. I know you can run one and not the other but what is the difference between too. I cant find anywhere in the rule book where it says C or D.

    I know you have to run a D, but what is the difference and where does it say that?

    I don't have a rulebook handy, but I don't believe it says that outright. You may find some trouble when Collins puts his gizmo on top of your gizmo and the profile isn't even close. I know the C displaces quite a bit more air per revo. than the D, the exact number I'm not sure enough of to post anything.

    C Blower rule

    It does not say anything about c or d blower in the class rules part of the rule book, but you have to go to general regulations on screw superchargers I believe.

    The wording is no screw superchargers developed after April 1, 1997 are legal for competition.
