Main Line Nitrous Kit 50-150HP

The Nitrous Express Main Line Nitrous Kit 50–150 HP represents a direct-port wet nitrous oxide system engineered for EFI-equipped engines seeking significant, tunable horsepower gains without extensive fuel system modifications. This single-stage wet system delivers nitrous and fuel through the intake manifold, making it a proven choice for street and track applications where reliable, progressive power delivery matters.

The kit's 50–150 HP range reflects the variable output available through jetting selection and tuning, allowing builders to scale boost to their engine's capability and fuel octane. The included 10-pound aluminum bottle provides adequate capacity for multiple passes or sessions without frequent refilling. Universal EFI compatibility means integration works across domestic and import platforms, provided the fuel injectors and engine management can support the added fuel demand. The white powdercoat finish resists corrosion typical in engine bay environments, protecting the bottle during long-term storage and repeated use cycles.

This system suits builders targeting modest yet measurable power increases on naturally aspirated engines, weekend drag racers, and owners seeking transient torque gains for roll racing or highway pulls. Wet systems inject fuel alongside nitrous, reducing detonation risk compared to dry systems and maintaining drivability during low-load cruising. Experienced tuners and shop installers familiar with nitrous plumbing and jetting will find this kit's direct-port design straightforward to adapt to most EFI powerplants, provided adequate fuel supply and ignition timing control are confirmed before activation.
