All race cars competing in motorsports must carry a properly mounted and secured fire extinguisher within reach of the driver. But a racing fire suppression system goes further, distributing a fire-suppressing agent to multiple areas of the vehicle simultaneously. Already required in F1, NASCAR, and other premier divisions, on-board systems are now mandatory in many circle track classes, including dirt modifieds, late models, and sprints.

Mandatory or not, having on-board protection can make all the difference in an emergency. While fire-retardant clothing helps protect the driver, a properly installed fire suppression system helps contain flames in the cockpit, engine bay, or fuel cell area before they can spread. Our guide explains how race car fire suppression systems work, how to choose the right size and configuration, and what’s required under SFI 17.1 specifications.

How To Choose the Right Size Race Car Fire Suppression System

Selecting the right race car fire suppression system depends primarily on vehicle weight, engine type, and sanctioning body rules. Bottle size refers to the amount of fire-suppressing agent inside the cylinder, not its overall weight. Larger and heavier race cars typically require larger bottles to provide adequate coverage for the cockpit and fuel cell area.

For most circle track applications, a 5- or 10-pound bottle is standard. Lightweight Sprint cars often run 5-pound setups, while heavier dirt modified and late model cars commonly require 10-pound options. Always verify minimum requirements with your sanctioning body to ensure your racing fire suppression system is compliant.

Recommended Fire Suppression System Size by Vehicle Type

Choosing the correct fire suppression system for race car applications ensures adequate coverage and helps prevent under-sizing a setup for larger vehicles.

Should I Choose a Manual or Automatic Fire Suppression System?

For most circle track racers, a manual race car fire suppression system is the standard choice. Manual versions use a pull cable or push-button actuator that the driver activates in the event of a fire. They are simple, reliable, and widely accepted under SFI 17.1 rules.

Automatic versions activate when heat or flame is detected. They provide an added layer of protection if a driver is unable to trigger the bottle manually.

If your series does not require automatic activation, many racers choose manual setups for their simplicity and proven reliability.

Fire Suppression Installation Best Practices

Proper installation is critical to ensure your race car fire suppression system performs as intended under SFI 17.1 rules. While manufacturer instructions should always be followed, these general guidelines apply to most FireBottle and similar setups.

Cylinder Mounting

Mount the fire bottle securely using an approved bracket. In most circle track cars, the cylinder is installed:

• Horizontally in the center of the open bay with the valve facing rearward, or
• Vertically, with the nozzle pointed upward

Do not install the bottle with the nozzle facing downward. An inverted cylinder can prevent proper discharge and compromise performance.

For systems such as the AMRC-1002 or FIRFC1002:

• Automatic two-nozzle assemblies typically route one line to the driver compartment and one to the fuel cell area.
• Manual three-nozzle configurations commonly use one nozzle in the cockpit and two in the engine bay for broader coverage.

Nozzle placement should prioritize driver protection and fuel containment areas.

Remote Cable Installation (Manual Systems)

Manual systems use a pull cable or actuator to deploy the bottle.

• Route the cable through a secure dash or bracket opening.
• Ensure the cable housing is fully seated in the activation head before tightening.
• Secure excess cable along the roll cage to prevent movement or damage.
• Keep the bend radius gentle to avoid binding.
• Remove the safety pin only after installation is complete and the vehicle is ready for use.

Push-button styles do not require remote cable installation.

Installation Tips

• Route cables where they cannot be crushed or damaged in a collision.
• Use a solid mounting bracket for the pull handle to withstand activation force.
• Keep the safety pin installed during transport or storage.
• Cover discharge nozzles when washing the car to prevent contamination.

A properly installed fire suppression system should remain secure, protected from impact, and compliant with activation and mounting requirements.

Racing Fire Suppression System Maintenance

Routine maintenance helps keep your system functioning properly in the event of an emergency. Inspect your unit every few months and before the start of a new racing season.

Before servicing any fire suppression system, insert the safety pin to prevent accidental discharge.

Routine Inspection Checklist

• Remove the activation head and inspect the firing mechanism.
• Clean and lightly lubricate the firing pin assembly using a high-quality lubricating grease designed for racing applications.
• Blow out discharge lines with compressed air to remove dirt or blockages.
• Inspect pull cables for fraying, corrosion, or debris.
• Check distribution tubing for damage or obstruction.
• Confirm all cable housings are properly seated and secured.
• Replace any worn, rusted, or damaged components.

Once inspected, reassemble the unit, secure all cables, and remove the safety pin only when the vehicle is ready for operation.

Keeping valve assemblies, cables, and tubing clean and properly lubricated with approved racing lubricants helps prevent corrosion and ensures reliable discharge when needed.

FireBottle & Fire Suppression System Recertification & Recharge

Most FireBottle and fire suppression systems under six years of age can be recertified and recharged according to manufacturer guidelines. Once the equipment exceeds six years from its manufacture date, replacement is recommended to maintain compliance and safety.

Always follow manufacturer and sanctioning body requirements for inspection and service intervals to keep your system race-legal.

SFI 17.1 Specifications for On-Board Fire Suppression Systems

Most circle track series require an SFI 17.1 fire suppression system. This specification governs performance, discharge standards, labeling, and recertification requirements for any approved equipment.

Here’s a simplified compliance overview:

SFI 17.1 Performance Requirements

• Discharge Performance: The system must discharge at least 95% of the fire-suppressing agent and extinguish a fire within 10 seconds.
• Engine Compartment Testing:
• Rear-engine vehicles: fire must be extinguished within 10 seconds.
• Front-engine vehicles: fire must be extinguished within 20 seconds.
• No flame re-ignition is permitted.
• Automatic Activation (if equipped): Thermostat actuators must activate the system within 15 seconds.

Certification & Labeling

• The manufacturer must submit test results for approval under the SFI program.
• Each cylinder must display a valid SFI conformance label.
• Manufacturers must revalidate performance every 48 months or when design changes occur.

When purchasing a fire suppression system for use in a racecar, always verify that the bottle carries a current SFI 17.1 conformance label. Without it, the unit may not pass technical inspection.

Frequently Asked Questions About Race Car Fire Suppression Systems

Are fire suppression systems required in race cars?

Many premier series—including F1 and NASCAR—require a race car fire suppression system, and more circle track classes such as dirt modifieds, late models, and sprint cars are adopting similar rules. Requirements vary by sanctioning body, so always check your rulebook to confirm whether an SFI 17.1–approved system is mandatory for your class.

Do I still need a fire extinguisher if I have a suppression system?

Yes. Most tracks still require a properly mounted handheld fire extinguisher, even if your vehicle has an on-board fire suppression system. A suppression system protects multiple areas of the car at once, while a handheld extinguisher provides additional backup for the driver or safety crew.

What is the best race car fire suppression system?

The best race car fire suppression system is one that meets SFI 17.1 requirements, matches your vehicle weight and class rules, and provides adequate coverage for the cockpit and fuel cell area. Many circle track racers choose FireBottle for its reliability and series approvals, while some applications may require FIA-approved options such as OMP.

What does SFI 17.1 require for fire suppression systems?

SFI 17.1 sets the performance standards for fire suppression systems. The unit must discharge at least 95% of its agent and extinguish a fire within specified time limits, with no flame re-ignition. Each bottle must carry a valid SFI 17.1 conformance label to pass technical inspection.
