The driver can also dampen the movement by “Bump Box’ing” through the brakes, as Davis explains it. The Bump Box is adjustable, using a pair of knobs (both a “fine” and “coarse” adjustment) on the face of the device to make minute changes in how far the car rolls forward and at what rate it does it. For drag racers, there’s a thousand ways to do everything.”
Some like it to set up hard because they think it preloads the tires and suspension, but others think that’s part of the problem. “It can be made to move smoothly or it can be hard if you want it to be that way. Davis, one of the best with electronics in the business, set out to create a product that could deliver a very brief signal to the solenoid, allowing for a more precise range of movement - a pulse, of sorts, so minuscule that it could harness thousands of horsepower ready to pounce and make it roll forward as delicately as a toy pushed by the wind if you choose to set it up that way. The Bump Box is a stand-alone device that uses your transmission’s transbrake solenoid to control the forward motion of the race car. So you’ve heard what the Bump Box is designed to do, but how does it work? Let’s answer that. We ran bigger brakes and dual rear calipers, which resulted in more weight and extra hardware.

You can see here just how small the Bump Box truly is, neatly tucked away in the El General twin-turbo Pro Modified owned by Joe Gonzalez and driven by Eric Dillard.Īs veteran racer David Hance shared with us, “There were specific things we had to do with our car to help with staging before we had the Bump Box.

As Davis tells us, many of the top racers - from doorslammer newcomers like Melanie Troxel and Leah Pruett to experienced drivers like Todd Tutterow - all commented how easy it was to use, calling it a no-brainer tool in their arsenal. Problem was, the brakes either wouldn’t hold the car at all, or when released, wouldn’t re-grab and cause the driver to either deep stage or jump through the beams. These racers had to hold the car against the brakes, spool the turbos, and then try easing off the brakes to bump into the stage beam, all while holding back a couple thousand horsepower. You just push a button and it moves the car forward half an inch, instead of letting off the brake and moving forward an unknown amount and hoping you don’t roll through the beams.”ĭavis originally developed the Bump Box for turbocharged racers who were having difficulty with the staging process. Although an unadvertised product at the time, the Bump Box first made waves at the PRI Show in 2011, where Davis set the record straight from curious show-goers wondering if the device made cars capable of staging and launching on their own by explaining that, “…it’s not automatic nor is it magic.
You just push a button and it moves the car forward half an inch, instead of letting off the brake and moving forward an unknown amount and hoping you don’t roll the beams. For many, this relatively simple device that uses just the push of a button to roll a car forward a specific distance, is a tool many are unsure how they ever did without. The Bump Box, so named for its use as a device to assist in the staging process known as “bumping in”, is the newest product from Davis Technologies, and not only has it cured the ills of turbocharged Pro Modified racers who were in dire need of a solution, but its found its way into untold numbers of race cars, from bracket racing on up. Two years ago, auto racing electronics wizard Shannon Davis set out to develop a first-of-its-kind product designed to alleviate a common problem for drivers of turbocharged race cars, and in the process, he created and mass produced what has become a vital tool for drag racers at every level and with every form of engine and power adder combination. But the benefits were soon realized by everyone from the blown and nitrous competition to bracket racers and everywhere between. The Bump Box was originally developed as a solution for turbocharged Pro Modified racers, who were resorting to other measures to keep from rolling through the lights as they built boost and tripped the stage bulb.
