What size jets to use??

[Skinny]

Alright. I'm using a 46/26(nitrous/fuel..or maybe a 28.. can't remember) for my 75 shot. If I was to run a 100 shot, what should I use? Jet sizes is the one thing about nitrous that just totally baffles me. I knew to use my current configuration only because someone told me. Where/how can I learn what to use? I don't even know where to begin.

it is 52N 33F

Are you sure about that? I've heard that NX sizes are different.

[pgriffith]

what kit do you have?

NX: 100= 52/28
75= 41/24

[pgriffith]

I called NX tech and got these answers(read post)

I called again and got different for the 75 shot. 41/24 which is what I am currently using and it works great.

I have a NOS 5175 kit converted to wet. I called NOS tech today and the moron told me to use 46/30 for a 100 shot... I'm using 46/26 for my 75 shot.. :rolleyes:

OK so we know the brand, nos kit
This has been a problem I have experienced.
I call the nos tech line and ask about jet sizes and hp ratings.
I have called and each time one tech tells me one hp level and another call they will tell me another level.
I was once told that the 120 hp jets I was running are actually 150 hp
I then informed them that I dynoed 111 hp more with the 120 shot.
They are useless.
63 is a 120 shot
I don't remeber the 85 hp shot, 100 shot I never tried.
Someone needs to dyno it to get a definate answer

Ok, ran a 52/32 combo.. seemed to work nicely...

[aarong20]

I believe the 85 shot is the .047 jet? That's the only jet that came with my 5175 kit I just got it two weeks ago..

[12secondv6]

Yeah, I think you are correct.
47 is nitrous 85 hp rating on a nos kit 5175.
Jeez, it's been soooo long since I've ever had that shot in the bird [img]tongue.gif[/img]

[aarong20]

James are these jets interchangable through NOS? I actually lost my .047 jet and my friend had one that came with his Nos kit for his cobra can I just use his or do I hafta buy another jet? also there is a jet that goes into the t-fitting its called a "flair jet" is that just the spare jet that came with the kit? it said like 28 or something on it..

[Skinny]

Yes the jets are interchangeable, as long as they are the same size. Any .047 jet has the same size hole at the tip. The jet in your t-fitting needs to stay there. I'm not entirely sure what that one does, since I never used that section of the kit because I converted mine to wet.

The jet in the t is for vaccum or is known as a 'fuel' jet on a dry kit. It is not like a fuel jet on a wet kit. That jet alloys the fuel psi to raise to the appropriate level
