CLASS WARFARE

-

DRAG Challenge entrants are divided into five classes: Haltech Radial Blown, Turbosmart Outlaw Blown, Pacemaker Radial Aspirated, Tuff Mounts Outlaw Aspirated, and K&N Dial Your Own. Cars running on a 275-or-smaller tyre run in the Radial classes, while ‘big-tyre’ cars run in the Outlaw brackets. The tyre classes are then divided into aspirated and blown, with the latter encompassi­ng turbocharg­ed, supercharg­ed, and nitrous-boosted engine combos. The tyre classes see competitor­s submit their best timeslip every day before leaving the track, with each ET added together into a cumulative score. At the end of Day Five, the car with the lowest cumulative ET is declared the winner. The fifth class is the huge Dial Your Own bracket, which had over 80 entrants. Cars in DYO don’t run a cumulative time; instead the slip they hand in on Day One is their nominated time they need to try and match over the ensuing four days. This sounds simple in theory, but this class normally comes down to thousandth­s of a second after five days of ballsto-the-wall racing, as it did this year.
