Nitrous Master Nitrous Oxide Systems Open Flow Test Kit

This kit allows you to test, analyze and set your
nitrous fuel system for optimum performance.

Most Complete kit available

Works with plates, nozzles, single or multi stage systems.

Digital gauge reads in 2/10 lb increments.

Built in zero button means "zero" is always zero,
whether racing at the beach or in the mountains!!

Can be used in conjunction with our Bottle Scale and Nitrous Master software to do your own flow testing.

How and why it works:

The different size jets used with this tool simulate the pressure at your jets or nozzles.
The "flow jet" is the same equivalent area as your total number of fuel jets or nozzles.

The on/off valve simulates pressures of the solenoid open or closed.

Available in 6 different basic versions.

Note: The only difference in the kits is the jet sizes.
While you can have any jet size you want the versions below carry some of the most used jet sizes. You can start with any version and buy any extra jets sizes you need later
OR if you know what you need we will change out the jets to your requested sizes.

Single Jet Method:

For those that prefer the one jet size fits all method. Request the size you want and we will swap out one of the standard jet sizes for your preferred size.
