High Volume Kit for Up To 300 RWHP Gain!
Nitrous Oxide Systems (NOS) has long been one of the most recognized names in nitrous oxide kits. The NOS Big Shot dual stage nitrous kit is their more race oriented kit. Racers know that a nitrous kit is an easy and affordable way to add big power to your engine, but sometimes when you add too much power at once you begin to have traction issues. The NOS Dual-Stage Big Shot addresses this by allowing you to run a smaller initial shot and transition to a larger shot once the car is moving. This is great for race cars or high horsepower street cars that can't get traction with a full 300 shot.

Complete Kit
This NOS Big Shot squarebore nitrous kit is a complete kit, utilizing large solenoids for high volume and includes everything you need to get started. You can just bolt it on, wire it up, fill the bottle and you're good to go. Some additional accessories may be helpful depending upon the intended usage. Most racers will opt for a nitrous controller for maximum control of both stages at the track, but it can be set up a number of ways.

Easy Installation
NOS Big Shot nitrous kits can typically be installed in a couple of hours and only requires basic tools. Wiring the solenoids and activation switch is very simple using the detailed instructions included in the kit.

Tuning Notes
NOS Big Shot systems are designed for use on highly modified engines and is intended primarily for competition applications. To supply the proper amount of fuel to the carburetor and Big Shot system, a fuel pump must be used that is designed to operate between 5 and 10 psi, with a flow rate of at least 0.1 gallons per horsepower per hour at 6 psi. High cylinder pressures are generated with the use of these kits and this greatly increases the load on internal engine components.

Fits
Most V8 Engines with Holley, Carter or other Sqaurebore Style Carburetors
