What is the horsepower range of this Nitrous Express kit?

The Hitman Plus kit comes standard with four adjustable horsepower settings: 50, 100, 150, and 200 HP. It is also upgradeable to 300 HP with additional components.

Does this kit include a nitrous bottle?

No, this is the 'w/o Bottle' version of the kit, meaning the nitrous bottle is not included. You will need to purchase a compatible nitrous bottle separately.

What makes the Phase 3 nitrous plate different from older designs?

The Phase 3 plate is an updated design that offers superior fuel and nitrous distribution and outstanding atomization. It eliminates the need for traditional spray bars, which can sag, split, or block airflow, ensuring more reliable performance.

Product Details

Nitrous Express is known for making nitrous systems that offer a lot of bang for your buck, and the Hitman Plus kit is a prime example. If you're looking to add a significant power boost to your 4-barrel carburetor-equipped vehicle without breaking the bank, this kit is designed for you. It's an excellent entry point for anyone new to nitrous oxide, offering a straightforward way to experience the thrill of extra horsepower.

This 'Hitman Plus' system builds on the original 'Hitman' design with an improved Phase 3 nitrous plate. This plate is engineered for superior fuel and nitrous distribution, ensuring a more consistent and powerful charge to your engine. Unlike older designs with spray bars that can sag or block airflow, this plate technology is built to last and perform reliably. It comes with four adjustable horsepower settings right out of the box: 50, 100, 150, and 200 HP. For even more power, it's upgradeable to 300 HP with a larger solenoid and different jetting, and can even reach Stage Six capability down the line.

Included in the kit is a 40-amp relay to handle the electrical load, a wide-open throttle (WOT) switch that ensures nitrous is only activated when your engine is demanding maximum power, and a bracket for mounting the switch. Please note that this kit does not include a nitrous bottle, so you'll need to source that separately. Also, this system is not CARB approved and cannot be shipped to California.
