when the bottle is full, its temp will pretty much tell you the pressure..lets say the bottle is full mind you...if the bottle is 85 degree's, pressure will be about 850 or so....but as its emptied , the temp will go down... and make sure your fuel system is up to snuff.

but keep a eye on your 02 sensors..i always seem them dieing alot with the spray cars. its better to be a little fat , then too lean.and the colder it is outside, the richer you need it to be..best bet is to pull the plugs after a pull, and see how they read. white is not good.

OMG you need a pressure gauge lol!!! that 85* 850 psi garbage what you gonna measure the bottle temp with????

most nitrous kits recommend no less than 975, i keep mine at 1100, if the pressure isnt high enough you could not be getting the whole effect of the spray!

Spray a car at 850 full and then 1100 full and feel the difference!! if you cant feel it look at your time slip,if you get to 1200 better purge could hold the solenoid open, ouch!!

buy a damn 30$ gauge, thats why nitrous has a bad rep, sh*t aint right blows up and ( it sucks cause you went cheapazz on your setup!!) oh my god nitrous sucks blah blah blah!

I have a simply question im new to the nitrous world but i bought a nitrous outlet 2v plate kit i was wondering if ill be fine running 100 shot to start off with? It has the WOT switch and i also have a window switch set for 3000-5000 rpm is that a good widow for the nos to kick in?

^^^ A 100 shot is totally fine as long as you have a tune for it. If it's a wet kit, you could probably get away with no tuning, but i would never do it personally.

I would spray it between 3-6k, or at least to 5.5k.

YIKES !!!!! did it blow up yet ?

use stock coppers gapped at .040-.042" if your scared you can 1 step colder but it's not really needed

time it about 10* with 92 octane

if it's cooler out you can run it harder..... i typically spray 80 on 10* and 89 octane as long as it isn't hotter than 75* or so

nitrous_bob

yes, thats extremely conservative

i spray all stock cars from the hole. i launch hard and never lift til i finish. ain't broke nuthin yet in over 12 years of spraying.... 3 diff cars and 3 diff kits

nitrous_bob

and as far as pressure goes ???

i consider my bottle empty when it gets lower than 800, i like my bottle 85-90*

bare minimum is 75* or more

i like pressure to be 1000-1200 psi

Im getting a backfire between gears sometimes when I spray.. Whats that about? And I bought a Professional Products fuel pressure regulator (adjustable) how much should i turn up my stock 19lbers? if its gotta run a lil fat and im switchin my nos jets to 100 from 75. Haha I came back from a 9 day training evolution right.. Get in my car to take it for a cruise nice and easy ya kno? I have a $hitty vibration when i let off the pedal 50mph and up.. gets worse the faster im movin.. 100mph got bad. Rearend or driveshaft? was fine when i parked it..

floodzilla

two stages of 600 shot easily.

nitrous_bob

hard to say, you lift on shifts ??? what are all your settings ? try dropping to 100 jets and check it out


dry kits spike fuel by themselves, you should see about 80 psig

so i'd set it at 42 w/ vac off so it's like stock
