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


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!

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.

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.

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 2023, this will be apply to Mildura’s Sunset Strip and South Coast Raceway.


Racer A runs 11.520 at the Heathcote Park quarter mile and a 7.50 at Mildura’s eighth mile
(x1.555=11.662) and 11.55 at Heathcote 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 Dragway at the Bend, 7.032 at Mildura (x1.555=10.935) and 11.012 at The Bend. 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.
