Information Bulletin

ERIE, MI (June 30, 2018) – There have been a few questions recently among Engine Pro Sprints On Dirt presented by ARP competitors.  This bulletin is being provided for the benefit of SOD teams.

As with any speedways and series, it is the responsibility of each team to know the rules that they are racing under.  The complete Sprint On Dirt rule book is available online at https://goo.gl/xZEoMG.

 Raceceivers

The Sprints On Dirt default channel is now channel 000, 454.0000 frequency.  This is the channel the raceceiver will default to when replacing the battery.  It may be necessary to use another channel at times, and it will be announced at the speedway when required.  INSTALL A NEW BATTERY FOR EACH RACE DAY.

Unaltered mufflers or inserts are required at all tracks.  Inserts can be purchased from Sprints On Dirt at every race.
