Dial Your Own at Street Machine Drag Challenge explained

Confused about Dial Your Own racing? Here's a run down of how it all works

Drag Challenge DYO 5 nw

THE Dial Your Own class at our Street Machine Drag Challenge events is always very hard-fought. Finishing in the top 10 earns any racer massive kudos, but not everyone understands how the competition works – let’s sort that out now!

2015 Drag Challenge DYO winner, Alysha Teale   

Dial Your Own is for entrants who don’t wish to compete in the ‘tyre classes’. DYO racing is all about consistency, so we will be looking for the most consistent cars across the three tracks. Your quickest and slowest times from the three tracks will be used to calculate your spread, and this will determine your finishing result.

2016 Drag Challenge DYO winner, Benny Philips  

We will be measuring the spread down to as many decimal places as necessary to determine a result. Entrants can make as many passes in the time allowed as they like, but they must provide one timeslip to the nominated Drag Challenge official before each day’s cut-off time. We reserve the right to limit passes if weather or other factors come into play and we need to get other cars down the track.

2017 Drag Challenge DYO winner, Blake Jefferys 

Because we compete at both eighth-mile and quarter-mile tracks, we will have to adjust some times to suit. All eighth-mile times are multiplied by 1.555 to create a quarter-mile time – at Drag Challenge Weekend, this will be apply to Warwick Dragway only.


Racer A runs 11.520 at Willowbank, 7.50 at Warwick Dragway
(x1.555=11.662) and 11.55 at Willowbank again. His quickest time is 11.520 and the slowest is 11.662, which gives him a spread of 0.142.

Racer B runs 10.985 at Willowbank, 7.032 at Warwick (x1.555=10.935) and 11.012 at Willowbank. Her quickest time is 10.935 and slowest 11.012, which gives her a spread of 0.077.

In this scenario Racer B would be the winner.
