Attention all Sportsman teams: The rules for sportsman currently state that the maximum RPM for the rev limiting box is 6000. This is incorrect. The wording should be this:

“The car must be fitted with one (1) unaltered approved MSD/DIRTcar RPM (rev) limiting box, maximum 6200 RPM with adjustment if necessary.”

This is effective immediately. This Tech Bulletin supersedes the rules as currently published. The rules will be updated on the website later today, April 16th.

If you have questions about this tech bulletin, please call the office and leave a message.
