The Nitrous Express SAFE (Stand Alone Fuel Enrichment) system improves the performance of any nitrous system. The SAFE system includes a one gallon, high strength, composite fuel cell that can be mounted in most factory battery trays without modification. The SAFE system also reduces the need to upgrade OEM fuel pumps, and will completely eliminate pressure drop at the fuel rail in EFI vehicles. The tank includes an integrated fuel level gauge and all mounting hardware for a no hassle installation! This methanol version comes preassembled with dual, self regulating, internally mounted fuel pumps that support up to 300 nitrous horsepower. Enriching nitrous with methanol provides huge torque gains, detonation resistance and the ability to run standard timing. Methanol is unleaded so it will not harm your o2 sensors. Overall, methanol is the best choice for nitrous/fuel enrichment. Note: special jetting patterns are required.
