I'm installing a stand alone and using a Holley blue at 14psi. I have an NX wet kit at 150 shot with fuel coming off the fuel rail using a .38F. What NX jet should I go with when I move it to the holley blue?

Will I need a regulator with that small of pressure pump?

TIA

Hey Sarge,

The best thing to do will be to use a regulator and bring down the pressure to 10 psi then I can get you the jetting for that!

How are you spraying your car?? Nozzle? MAF?

Thanks Clay @NX

 

I'd go lower then 10 with the fuel pressure. Foggers we run anywhere from 5 to 6 psi, depending on the jet spread.

Lower pressure, means bigger jet, less chance of it getting clogged.

 

Using a shark nozzle. Wet kit, after MAF.

Just checked and the regulator comes with my pump. So I can dial it down to 10.

 

That is very true!
You can run it at 5 psi as well...

Here is our jetting for a 150 shot:

5psi: 62n/57f

10psi: 62n/46f

 

Thanks

Can you get me the numbers for a 175 and 200 shot?

Thanks

 

We recommend to use 10+ psi on 175 shot and up.

175hp = 73n/52f

200hp = 78n/57f

If you need anything else you know where to find me!
