Pro ET Rules:

All bikes must pass basic NHRA tech inspection (performed by track official). Wheelie-bars required. Slicks or DOT tires OK.
Split-tree, no delay-boxes, playback data recorders OK.

Time-trial passes prior to eliminations will be grouped with Street ET and split into .500 Full Tree and .400 Pro Tree.

Bikes will be laddered randomly on a NHRA sportsman ladder. Lane choice will be by best RT in qualifying and best RT in previous round in subsequent rounds (each pair of racers will determine this on their own. No printouts of RT’s will be available).

All dial-ins will be on bike, and include a “P” if a .400 pro tree is desired. It is up to the racer to make sure their dial is correct on the board before staging. Also, different tracks may use either the Pro or Full tree as the default. It is up to the racer to make sure the symbol on the board is correct.
