All You need to know about Dry NOS Kit for 5.0L

This is actually brought over from corral but figured I would post some stuff here and also have the link posted to the other forum where there is more stuff.


Here are some of the jetting sizes for a NOS kit:

19LB (stock) Injectors (orange top)
59 fuel/ 42 NOS = 75 HP
53 fuel/ 47 NOS = 100 HP OR 100HP 49F 55N
42 fuel/ 59 NOS = 125 HP
42 fuel/ 67 NOS = 150 HP *
42 fuel/ 73 NOS = 175 HP* (this is the max that the stock solenoids will flow).

24 LB Injectors (light blue top)
63 fuel/ 42 NOS = 75 HP
57 fuel/ 47 NOS = 100 HP
51 fuel/ 55 NOS = 125 HP
45 fuel/ 67 NOS = 150 HP*
42 fuel/ 73 NOS = 175 HP* (this is the max that the stock solenoids will flow)

30LB Injectors (red top)
67 fuel/ 42 NOS = 75 HP
63 fuel/ 47 NOS = 100 HP
61 fuel/ 55 NOS = 125 HP
53 fuel/ 67 NOS = 150 HP*
45 fuel/ 73 NOS = 175 HP* (this is the max that the stock solenoids will flow).

36LB Injectors (dark blue top)
70 fuel/ 42 NOS = 75 HP
67 fuel/ 47 NOS = 100 HP
65 fuel/ 55 NOS = 125 HP
57 fuel/ 67 NOS = 150 HP*
48 fuel/ 73 NOS = 175 HP* (this is the max that the stock solenoids will flow).

42LB Injectors (lime green top)
75 fuel/ 42 NOS = 75 HP
70 fuel/ 47 NOS = 100 HP
67 fuel/ 55 NOS = 125 HP

This is for the NOS Purge Kit

This is the Wiring Diagram that I made up and used for my car, Its a little different then the NOS way for the Kit and also a Purge kit:

***One other thing that would be recommended to do is to get a Window Switch...with this you will be able to spray through certain rpms....example would be 3000rpms to 5000rpms.

Here is a window switch at Summit Racing:

Dry or wet shot?

Are all the jets the same for different brands. like ZEX, Nitrous works, etc.?

 

[Danman765432]

i believe the jets are all the same, i believe they all go by the same increminents such as .47 and .59 are some examples, if the jets vary in size (meaning if they will fit into different nozzles) this i do not know. (maybe someone can help me out with this) however the systems are hooked up differently...the thing with the NOS system is that they use something called a Bypass Tee. In this Bypass Tee there is also a jet. This bypass tee causes vacuum and tells the computer to send it more fuel, this is how the NOS system compensates for adding more fuel. In the jets above it says Fuel/Nitrous. Where it says fuel, that means the size of the jet that is in the Bypass Tee and the Nitrous is the size of the jet going into the nozzle.
