NOS 05001 Powershot Nitrous System Kit
The NOS 05001 Powershot kit focuses on delivering a controlled, safe application of nitrous power. It emphasizes a smooth power surge on demand and is designed to avoid affecting fuel economy during normal driving. This makes it suitable for enthusiasts who want a noticeable, track-ready boost without compromising daily reliability. Installation requires attention to manifold clearance and proper tuning to prevent engine knock and ensure consistent nitrous delivery under load.
NOS 16037 Intimidator Illuminated Dual LED Nitrous Purge Kit
The 16037 Intimidator Purge Kit uses dual blue LEDs to illuminate a nitrous purge plume, providing a visually striking display and a practical purge function. The kit helps clear the lines of any residual liquid nitrous and vapor before activation, contributing to more consistent pressure and nitrous flow. It’s aimed at drivers who want a standout purge effect for show and improved system reliability during high-demand applications.
NOS 16030-4AN Line Purge Valve Kit
The 16030-4AN Line Purge Valve Kit is designed to release trapped air or gaseous nitrous from feed lines, promoting consistent performance. It includes all components needed for an easy installation and is backed by a 90-day limited warranty. For builders prioritizing purge reliability—and wanting to ensure pure nitrous delivery from the bottle to the nozzle—the purge kit is a practical addition to a multi-component NOS system.
NOS 14164 Nitrous Bottle Heater Kit
The NOS 14164 Nitrous Bottle Heater Kit is calibrated for optimal performance by maintaining proper bottle pressure through thermostatic control. This helps ensure that the nitrous system delivers consistent performance across temperature variations. The heater kit is a focused upgrade for users who operate in varied climates or track environments where bottle pressure stability is critical for repeatable power delivery.
Buying Guide: Key Considerations For Choosing A NOS Kit
- Vehicle compatibility: Confirm engine type (carbureted vs. fuel-injected), manifold space, and carburetor compatibility to ensure the NOS kit fits cleanly and integrates with existing controls.
- Single-stage vs. multi-stage: Single-stage systems are simpler and often easier to tune, while multi-stage setups provide higher power at the expense of more complex installation and tuning.
- Purging reliability: Purge components improve consistency by removing air from lines. Consider purge valves, purge kits, and purge switches as part of the system.
- Electrical integration: Check for compatible switches, relays, and micro-switches. Proper wiring and shielding reduce electrical interference with vehicle systems.
- Pressure management: Bottle heaters and pressure gauges help maintain stable nitrous pressure. Evaluate bottle heater compatibility with your climate and track conditions.
- Display and monitoring: Digital gauges and LED indicators provide quick real-time feedback. Choose displays that are easy to read at a glance, especially under race conditions.
- Installation and warranty: Look for complete installation kits and clear instructions. A reasonable warranty period reflects component quality and manufacturer support.
- Safety considerations: Ensure the kit includes or supports safe activation controls, proper fuel management, and adherence to local regulations and vehicle safety standards.
- Maintenance needs: Purge and line maintenance can affect long-term performance. Plan for routine checks on lines, seals, and fittings.
- Cost vs. benefit: Compare the total package, including bottles, lines, solenoids, and purge hardware. Balance upfront cost with expected performance gains and reliability.
Any NOS installation should prioritize safety, correct tuning, and adherence to local laws and racing regulations. Always consult a professional technician if you are unsure about installation or engine safety margins before using nitrous systems on public roads or race tracks.
