Any year, make, and model vehicles(Door Cars only.)
Dragsters and roadsters are prohibited.
The Open Comp class will run 2 qualifying passes with your quickest pass (ET) being your index # for the entire event.
Qualifying Information, Ladder Type, & Tree
The class will be qualified by positive reaction time closest to “.000”based on a Pro .500 Tree. “.000” is considered perfect. Any negative r/t will be placed at the bottom of the qualifying ladder, the more negative the r/t is, the farther down the ladder the run will be placed. For cases in which identical reaction times are made, qualifying position will be based on a first-come first served: the first occurring r/t will be placed #1, the second occurrence of said r/t will be placed #2, and so on.
Class will be paired according to qualifying positions, and then advance to eliminations.
All Run, NHRA Pro Ladder, Pro .500 Tree, Handicap Start.
A 32 or less car field will be laddered on a Pro style ladder
A 33 or greater car field is randomly paired and run until the field reaches 32 cars or less. When the field reaches 32 or less cars a Pro ladder for the number of cars remaining will be used to pair the cars. Car placement on this ladder will be determined based on reaction time for the last round that was randomly paired.

Deep Staging

It is always the driver’s responsibility to stage the vehicle prior to the tree being activated. In any event, the driver must be prepared to leave as soon as the final stage light is lit. A competitor with the words DEEP displayed on the window is not necessarily obligated to deep stage.
