I did a search but got conflicting answers. I know people with DP setup's typicaly use low pressure setups but was not sure about lower pressures with nozzle setup's. I was thinking of useing lower fuel pressure setting with my stand alone, I was thinking of jetting the nirous for a 150 shot but using a 200HP fuel jet, I then wanted to reduce the fuel pressure untill my A/F ratio was good. Is there anything wrong with using this methode with my dual NX shark nozzle setup? Your opinions are much appreciated. Thanks.

I can't see why this would be a problem. You will just need to have the correct jetting.
Going with a dual nozzle, it looks like a .045 jet for the nitrous in each nozzle and a .037 fuel (at 10PSI) in each nozzle. This should be right at 150rwhp shot (based on nitrous pressure of 1000PSI) and a good starting point for your A/F ratio.

Thanks for the reply, I'm tring to see if I can use a NX 33 size fuel jet on each nozzle and gradully lean it out. The strange thing is I already dropped the fuel pressure down to 12 PSI and I'm still pig rich. I only have 4 LBS of nitrous left in the 10 LBS bottle so maybe that has somthing to do with it.

The only thing I'd make sure is that the nozzle will still atomize the fuel the same at a lower pressure.

Nitrous is what atomizes the fuel not so much the fuel pressure.

Thanks for the replys, Anyone else have any opinions on using NX shark nozzles and low Fuel pressure. Please bear with me I'm still a nitrous newb.

Yes. Running the NX system at 10psi is no problem. You will just nee dthe correct jetting.

Is the above listed jettings for DUAL nozzle like SmaknaSS asked for?

It looks like single nozzle jetting to me.... You may want to check that before using it.

Sorry I was under the impression it was for a single nozzle system. I'll post the correct jetting in a bit.
