In SS can you shift on rpm or time?

I thought only RPM was allowed?

Using "the transbrake release" to start a timed event seems defiant of current rules in Super Stock?

Pretty sure the only things allowed to be hooked to the trans brake circuit is the brake solenoid and the rev limiter. They even frown on the replay tach connected to the brake circuit

You can shift by time if you use your wristwatch..

We always use RPM on our SS cars.
We do not wear watches.

You can do it with either if you use an MSD PowerGrid. They have a built in timer that can be used for any feature you would like. You can turn on a brake light at 5 seconds into the run if you so choose :)

Hmmm, I don't see any options for using MSD power grid in the rule book? Is this located somewhere else?

On the accepted list, page 79 it's MSD 7730 (this is the PN for PowerGrid).
