About a year ago, Dragzine introduced the world to Davis Technologies’ Profiler Wheel Speed Management System, a unique approach to power management designed to allow tuners to apply or reduce timing to a combination to navigate the available traction. The system relies on driveshaft speed to monitor traction and adds or subtracts power based on the data received from the driveshaft speed pickup.

The concept is a very simple premise: If the wheel speed is too high for a given point in the run, the car is losing traction and power should be reduced to bring the wheel speed back to the appropriate point. If the wheel speed is too low, more timing and power would be applied. The execution of this concept is hardly simple, however, and that is where Profiler’s creator Shannon Davis shines, taking his years of traction control knowledge and revamping it into a complete power management system like Profiler.

And the fruits of Shannon’s labor are really showing in the run sheets from some of the biggest races in the country. Davis spent last weekend updating his Facebook page with his customers’ progressions through the rounds at the Outlaw Street Car Reunion at Memphis International Raceway, and the names read like a murderer’s row of radial racing badasses: Jason Michalak, Brad Edwards, Mark Woodruff, Jared Johnston, Rich Bruder, and Kit Luong. Those guys made up 75% of the semi finalists in Pro Drag Radial and X275 at one of the most prestigious radial races in the nation. Michalak became the quickest man on radials during qualifying when he ran an effortless 3.97 at 194 MPH, to supplant Edwards from the No. 1 spot. Davis’ customers can now claim the only two three-second radial passes ever made in competiton.

Meanwhile, Johnston and Bruder have swapped the X275 world record back and forth a few times between them. Johnston currently holds the record at a blistering 4.44 with Bruder hot on his heels with a best of 4.45. Between the two of them, they account for the bulk of all X275 passes made quicker than 4.50 seconds, and they’re quick to point out that Davis and Profiler are huge factors in their go-fast equation.

With this level of success, it stands to reason you’ll be seeing more Profilers wired into any car looking to extract the maximum possible performance, which is the very essence of racing at it’s core.
