Installation & Maintenance Considerations
Proper Installation for Optimal Performance
ZEX Nitrous Oxide Systems are engineered for straightforward installation, but correct setup is essential for safe and reliable power delivery. Always follow the kit‑specific instructions and verify all electrical connections, fuel lines, and activation points before first use.
Fuel System Requirements
- Ensure your fuel pump and injectors (EFI) or carburetor (carbureted setups) can support the selected horsepower shot.
- Upgrading to a higher‑flow pump or regulator may be required for larger jets.
- Always confirm adequate fuel pressure under load.
Electrical & Activation Checks
- Verify throttle‑position activation (TPS) for EFI systems.
- Confirm all relays, switches, and safety devices are wired correctly.
- Test activation circuits with the engine OFF before live testing.
Bottle Mounting & Routing
- Mount the nitrous bottle at the recommended angle for proper siphon pickup.
- Use high‑quality brackets and secure all lines away from heat sources and moving components.
- Maintain clean, kink‑free routing for both nitrous and fuel lines.
Routine Maintenance
- Inspect solenoids regularly for wear, contamination, or sticking.
- Check all fittings and lines for leaks before each use.
- Replace bottle seals and filters as needed to maintain system integrity.
- Keep the nitrous bottle filled with high‑quality, uncontaminated N₂O.
Jetting & Tuning Adjustments
- Match jet sizes to your engine’s power level and fuel system capacity.
- Retard ignition timing as recommended for higher horsepower shots.
- Monitor air‑fuel ratios during tuning to ensure safe operation.
Cold Weather & Bottle Pressure
- Maintain proper bottle pressure (typically around 900–1,000 psi) for consistent performance.
- Use a bottle heater when necessary to stabilize pressure in colder conditions.
- Avoid overheating the bottle or exceeding recommended pressure limits.
Safety First
- Always use a wide‑open‑throttle (WOT) activation method or TPS‑based activation.
- Consider adding a window switch, purge kit, and fuel pressure safety switch for enhanced protection.
- Never activate nitrous at low RPM or under heavy load without proper airflow.
