Placerville, CA…With the season roughly two months away the Elk Grove Ford Sprint Car Challenge Tour presented by Abreu Vineyards has announced several technical and general rules updates for the fast-approaching campaign.
Some of the pertinent rule updates and modifications for this season include the implementation of fire suppression systems, along with an update to the weight rule, tires, aluminum block engines, double file restarts and guaranteed time in the work area. Traction control devices as always, are prohibited, and will present a stiff penalty if found.

Details of the updates can be found below. The full rulebook can be found at

-A fire suppression system that meets the SFI 17.3 specification must be installed and functional in all race cars at all times when competing at Sprint Car Challenge Tour events by May 1, 2023.

The fire suppression system must include a thermal trigger and a manual trigger, both mounted in the driver’s compartment. The thermal trigger must be in the lower area of the drivers compartment forward of the seat near the area of the fuel pump. The manual trigger must be mounted within reach of the driver on the forward left-hand side of the cockpit. A minimum of one nozzle must be mounted in the lower area of the cockpit forward of the seat.

The DOT approved cylinder manufactured of aluminum or steel must be securely mounted to the frame per the manufacturer’s instructions and the discretion of the Sprint Car Challenge Tour officials. The cylinder must have a minimum capacity of 5 lbs.

The system must be fully charged and display a legible and valid SFI 17.3 and manufacture label, easily viewable at any time by the Sprint Car Challenge Tour officials. Cylinders that are beyond useful certification date must be inspected, serviced and re-labeled by the manufacturer.

If a nozzle is connected to the cylinder with a line, the line must be steel or steel reinforced and must be triggered at the end of the line.
