what are the jet sizes for a dry kit (75hp-125hp).

 

.041 I think is 75 HP
.046-.047 is 100 HP
and .052 I think is 125 HP.

 

thanks for the info.

 

From OneFlyin95z28 45N+67F=80hp
49N+65F=100hp
72N+54F=175hp

 

Granted this guy wanted to know about just they nitrous part, but the fuel jet sizes you mentioned make no sense. From this, as you step up in nitrous, you step down in fuel. This must be for a carb setup or something because of how large the fuel jets are.

Just odd that as he steps up in nitrous jet, he steps down in fuel. I would think that would make it leaner as he went.

 

I am glad you mentioned this. The "fuel" jets mentioned are for the Nos #5176 kit which has a Tee'd in nitrous regulator to raise fuel pressure via the fuel pressure regulator. By putting progressively SMALLER jets in the line which feeds the nitrous regulator -to fuel pressure regulator - fuel pressure is INCREASED.

 

Thanks for the clarification!

I didn't realize that NOS wet kits used the tee'd regulator to boost fuel pressure. I ASSumed that was only for the dry kits to compensate for the nitrous.

 

Nah your right, It is just the dry kit that has the pressure tee, the 5176 is a dry kit.......the whole "fuel jet" thing on a dry kit is kinda confusing, they should just call them pressure jetts or something

 

Did you read the original question? He is asking for the jet sizes for a DRY N2O system? The NOS 5176 kit is a DRY kit. NOS does not use the "tee'd regulator" for their wet kits.

 

I read the original question, but had a major brain fart and forgot about the pressure regulator. I also didn't research to find that the 5176 kit is a dry kit.

Sorry.

 

My NOS #5176 dry nitrous system came with 67N/42F in 1996.
I believe Edelbrock uses the same size jets for their dry kit.
