I am going to use a single nozzle wet system for now and change to 4 nozzle later with 1 gal fuel cell and regulator just for the nitrous. I want to know what the best fuel psi to use is. I have herd around 10-12 psi but would the number change according to your nitrous setup? Also would a boost psi change mean a change in fuel jet sizes?

you should prolly post this in the power adders forum, they'd prolly be able to help you

when you spray, it will go up in boost a few pounds

Boost pressure has no bearing on what N20 jet you will use.
If you had a seperate fyel setup just for the nitrous I would just set the fuel pressure at 43.5
As long as you use the right fuel jet for the fule pressure you are running then the fuel pressure you choose isnt that important.
I say 43.5 because most kits will reccomend cetain jets based on you using 43.5psi fuel pressure.

am i right or wrong on that tom i think i am right but have never sprayed a turbo car all i have is hear say

Tom N

It can on smaller turbo.
If you have a good wastegate and free flowing exhaust it may not.
When I ran nitrous on a 60 trim with a .82a/r it wouldnt creep the boost at all. But on a 16g it would.

i was just basing it off of all of the srt4's who sprayed

most of the kits recomend 43 or 45 or even 40psi because you are using a line off of you exsisting fuel system. I have herd you would have less problems with a lower psi. like if you are using a .026 jet which is around 30.5hp at 43psi your fuel jet would be a .014 which is so small it's hard to see light through if a piece of dirt gets in it some how it would clog. anyways i will call a few differnt nitrous vendors in the morning and let everyome know what they say.

also i wasnt wodering it boost psi would rase but if you should change fuel jet sizes when you use a higher boost psi?

GsEclipse02

it should only go a few psi higher then normal just lower ur boost a few pounds
