Delay Box Racing 

For drag racers only: this month my “Dead-On” column will be directed a bit more towards the readers who actually race and a little less towards the editorial/opinion stuff. There are some things that I think are just the beginning of a problem that should be dealt with now. If you race in a class or bracket that does not allow delay boxes, PLEASE READ ON!


This is the new trans-brake switch that in reality is just a delay box in disguise. Even the instructions tell you to go out, if you red-light consistently you need to get a practice tree and adjust the amount of delay to put into the switch. So now you need a $350 switch, a $300 practice tree and several runs to get the "delay" set on your NHRA legal switch? Are you kidding me or what?


Most of you know that I race every week that I can get the dragster ready and afford to go to a race. I have been doing that for over 30 years and I just love it. I have seen the progression from 4-speeds to automatics. The introduction of transmission brakes made the automatic transmission cars leave like a stick car. Then came the MSD ignitions with rev limiting options and the natural addition of a 2-step rev-limiter that controlled start line RPM with an “rpm-chip” for both stick cars and trans-brake cars. Even cars without a trans-brake figured out how to launch “with the chip” by using four-wheel line locks. The use of tape on the windshield to block the other side of the tree or isolate the bottom bulb was

next. Then the delay boxes came out of the closet and into production by several companies but mainly it was Digital Delay, K&R and Dedenbear. They are still the three main players in the electronics drag racing world.

Did the delay box change drag racing? Yes, no doubt about it. Did it change it for the better? In my opinion, yes, no doubt about it. You cannot cheat if you use one when they are allowed. It is the No Box classes that deal with who may be cheating. Faster brackets that allow delay boxes made more cars and drivers competitive. It also leveled the playing field because there is a class that allows electronics and a class that doesn’t. Having those two brackets for a racer to choose from kept bracket racing uncomplicated and fair and it remained that way for probably 10 years. You either used a delay box or you didn’t, it was your choice.
