Here's how we do it, we just ask the driver to power up the car (no engine running) and push the TB button and listen for the Click after release...no delay means no delay. Usally we do this in the pits but when in doubt it has been done in the stageing lanes. We also stand at the starters box and watch when it is suspected.

After reading this post we will be checking Randys car twice dont forget the Meeting 3/29 @ 1pm
