just got nitrous system installed and went out and sprayed a couple of times and my pressure gauge doesnt drop a bit....bad gauge or what?....everything is BRAND NEW on system

 

thats normal. it wont start dropping unless volume declines 50% or temp of bottle goes below 70ish

 

What he said.

 

What was your bottle temp. at?

 

This is not correct. Bottle pressure is determined solely by temperature so long as any liquid nitrous remains.

 

i have absolutely no clue how to tell what the bottle temperature is at

 

Not exactly. As you flow and the liquid nitrous evaporates, it chills the remaining gas and drops the head pressure of the bottle.

And pressure in the bottle is directly proportional to temperature. At 70ish nitrous is only at around 650-700 psi.

 

Bottle pressure tells you the temperature.

Pressure (psi) Temp F
600................50
700................62
800................74
900................84
1000...............93

 

Very, very useful info there! Thanks! Looks like 88 - 89 should get me the 950 psi I need.

 

 

Lol guess I was wrong my pressure normally stays close to where I like to spray unless its pretty cold out.
