Speedworld Junior Dragster 2012 News
The 2012 Team Speedworld Team Junior Dragster schedule is TENTATIVELY posted at the bottom of the front page of the website. There are still several things yet to be worked out, including the matter of all of the JD Divisionals (as of 1/11/12). We'll try and get this resolved as quickly as possible.
Jr Dragster RULES
This includes the requirement for a full chain guard.
ALL cars must be equipped with a guard to cover the width and at least the top run to the forward and trailing centerline of the sprockets on any chains. Chain guards must be minimum .060" steel or .090" aluminum. Chain guard must be within 4" of the chain at all points. Must be securely mounted (no tie wraps). Plastic and carbon fiber chain guard prohibited."
The finishing touches are being put on the 2012 NHRA Jr. Drag Racing League Rulebook and it will soon be available for download on jrdragster.nhra.com, and in conjunction with its release, the NHRA Technical Department outlined amendments to rules for the 2012 edition. Rules amendments from 2011 to 2012 are minimal and include the areas of Jr. Dragster ballast and gauges and Jr. Comp drivetrain and ignition. The complete list of amendments is below.
