The Nitrous Outlet 8 Cylinder Nylon Direct Port Dry Jet Pack (part # 00-00389-DRY) is a direct port nitrous system from Texas-based Nitrous Outlet. This version is rated for 100–400 HP. A direct port nitrous system feeds nitrous and fuel to every cylinder through its own nozzle, which gives the most even cylinder-to-cylinder distribution and the highest horsepower ceiling of any nitrous setup. It is the choice for serious drag cars where every cylinder needs to make the same power.

Features & details

Frequently asked questions

How much horsepower does this nitrous system make?
It is jetted for 100–400 HP (jetting for 100, 200, 300, 400 HP). Start at the low end, check your plugs and timing, and step up from there.

Is this a wet or dry system?
This is a dry system: it sprays nitrous only, and the extra fuel comes from your fuel system and tune.

What else should I plan for when adding nitrous?
Most racers pair a nitrous kit with a bottle heater, a purge kit, a fuel pressure safety switch and colder spark plugs, and pull timing to suit the shot size. Call us at 713-938-4033 and we will help you spec the right combination.
