Nitrous Oxide Jet Calculator

Share |
I decided to write this app because I couldn't find anything web based at the time that would do this. Most of the info out on the internet required you to have a calculator or do the calculations in an Excel doc.

If you have a Palm PC running PalmOS 3.5 or later, or want to have a version that runs on your Laptop/Desktop PC, CLICK HERE.

Wanna see the car that I have the Nitrous Oxide installed on? It is my 1991 Geo Storm. Yea, yea. . .you say that now, but I'll still smoke you. Checkout my Storm project and the modifications I have done!

Until next time; "Get in, sit down, shut up, and hang on when I push the fun button!"

The Nitrous Jet Calculator will help you calculate Horse Power ratings for jets used in nitrous oxide systems. If you are using a 'wet' setup, you can calculate what the Fuel Jet size is by filling out the nitrous pressure and fuel pressure fields for a given Nitrous Jet.

To see the other downloadable versions of the Nitrous Jet calculator for the Palm and your computer, CLICK HERE

Fuel Pressure (PSI):
(info only needed if you are using a 'Wet' setup)

Nitrous Bottle Pressure:
(info only needed if you are using a 'Wet' setup)

Nitrous Jet Size:Thousandths of an inch.
(Will calculate Horse Power(HP) rating for jet)

Number of Jets/ports:
Single fogger/direct port/etc...




Results

The Fuel jet size should be 0.000" or 0.000mm

A Nitrous jet size of [NJ]" or mm should produce:
0.00 HP with [NP] port(s)

Actual HP to the wheels: 0.00 HP
