World of Outlaws Sprint Cars to Implement Fire Suppression System by 2023

Series Director Carlton Reimers and Technical Director Tom Devitt have confirmed an on-board fire suppression system will become mandatory to compete with the World of Outlaws NOS Energy Drink Sprint Car Series by the beginning of the 2023 season.

“We’ve had preliminary discussions about this for the last few years, so this has been the goal to get here for some time,” Devitt said. “I brought it up again at Knoxville last year and presented the rule to drivers and teams, and everyone was well receptive of it. We just have to go through the process of refining what exactly the rule will be. The two SFI standards right now don’t fit into a Sprint Car, so we’re creating a new 17.3 specification. It’ll take a bit of time, so that’s why we’re holding off until 2023.”


Titled the “Single Seat Open Wheel Front Engine On-Board Fire Suppression System,” the SFI has already drafted the 17.3 specification with finalization on the rule coming once research and development are complete. Due to the open cockpit of a sprint car, the SFI 17.3 specification is expected to be “tougher” to pass than other fire suppression specifications.

Series officials have already begun conducting cockpit nozzle tests, while the SFI will begin their research & development in late January. A specification is expected to be finalized by late spring or early summer.

FIRE SUPPRESSION SYSTEM: By the first event of 2023, fire suppression systems will be required for all World of Outlaws Sprint Car Series competitors. Sprint Car Safety Council members are in the process of working with SFI and manufacturers to develop a set of specifications which is anticipated to be completed by May 2022. It is anticipated that the specifications will include required number of nozzle(s) and their location, minimum 5lb system, bottle construction, type of mounting hardware, etc. It is recommended that anyone considering a sprint car fire suppression system should wait until the SFI specifications are released before making a purchase. If you intend to install a system before the SFI specification is completed, be aware you may be required to update it when the SFI specification is mandatory in 2023.
