Jetting Combinations:
If you plan to use a wet system, such as a single fogger nozzle, then you can use this chart to find the proper Nitrous and Fuel jets you will need. This chart displays the jetting for ONE fogger nozzle mounted on the intake of your engine. If you want to add more than 150 HP, you will need to add a second fogger nozzle alongside the first one, and then jet it according to how much extra nitrous/ fuel that is required. Also, this jetting chart is for an EFI, high pressure fuel system, not a low pressure carb system. This chart is based on 35-40 PSI of fuel pressure, similar to what a standard efi system will use.

FOR FUEL INJECTION ENGINES....
N2O / Fuel / Horsepower Gained.
34/18 40HP
37/22 50HP
39/24 60HP
41/26 70HP
43/28 80HP
46/30 100HP
52/33 125HP
61/38 150HP
For a carb setup running 5psi of fuel pressure, the basic jetting is as follows:
N2O / Fuel / Horsepower Gained.

38/46 50HP <Very Rich Jetting
46/53 75HP <Very Rich Jetting
57/65 100HP <Very Rich Jetting
47/53 100HP <NOS Jetting.
55/61 125HP <NOS Jetting.
73/82 150HP <NOS Jetting.
82/91 175HP <NOS Jetting.

Does the N2O increase the VOLUMETRIC EFFICIENCY. or not?

Come on guy's..... does anyone know that answer to that...

ofcource;;;
you'r going to use all ingen power. so the engin is working efficincy

Thanks for your answer Mr.Mustang,

But First we should know What is the VOLUMETRIC EFFICIENCY?

It is the measurement of how close the actual volumetric flow rate is to the theoretical volumetric flow rate. A engine has a set volume (displacement) that can be calculated. However, your engine will not use the full volume (100%) it has available because of friction losses, leaks, and the fact that a mass produced engine can only be so good before the money out weighs the benefits (the point of diminishing returns).

And now we are ready to learn How to calculate VOLUMETRIC EFFICIENCY?

It is simply the actual volumetric flow rate divided by the theoretical volumetric flow rate multiplied by one hundred. The Equation shows the volumetric efficiency using the data from the previous two equations. This will tell us the volumetric efficiency of our car at 5,993 rpm.

Equation

Where:

VE = Volumetric Efficiency (%)
AVF = Actual volumetric flow rate (ft3/minute)
TAF = Theoretical air flow rate (ft3/minute)

Solving for VE:

The results you get from your calculations should help you better understand how your car will react with future modifications. Be sure to establish a baseline and test your car after every modification.

Happy modifications :devil:
