Open Comp is usually run on a 5 tenths pro tree with a competitor getting a set "index" or "dial-in" for the race.
The way it works in NHRA division 2 is 1/8-mile, 5 tenths pro tree, transbrakes and 2 steps allowed, but no delay boxes and no throttle stops or timers. You get 2-3 time runs, and they drop .05 from the fastest pass for your index/dial-in. Example would be you run 7.22, 7.21 and 7.23, your index would be 7.16 for the weekend/night/whatever.
The way it works in NMCA/NMRA is 1/4-mile, 5 tenths pro tree, transbrakes and 2 steps allowed, but no delay boxes and no throttle stops or timers. You get 2-3 time runs, and they drop .10 from the fastest pass for your index/dial-in. Example would be you run 10.47, 10.52 and 10.49, your index would be 10.37 for the weekend.
As mentioned, some tracks / series run it a little differently. It's a lot of fun, we started running an Open Comp series at our local track 4 years ago, and this year NHRA division 2 added it, along with 6.50 and 7.50, to the classes that will run for a wally and a gold card at the ET finals in October.

One more question though. Do you leave at the same time or is it a delay for the fast car like normal ET races?
