Quick N20 question. - NJFBOA - Home of New Jersey's Camaros and Firebirds

I am borrowing Vinny's bottle for the time being, and I wanna "test" my system before the spring season.

Question is, with the bottle shut, can I take out this plug and install either my gauge or sender? The bottle is full or pretty close, so I don't wanna have a plug shoot me in the chest and then a face full of N20...

Its an NX bottle.

your gauge should be inline. that means u screw it to the fitting there on the right.

LTb1ow · 01-09-2010, 01:18 PM

Yea, not enough misc. parts to rig that up. Oh well.

S.J.SLEEPER · 01-09-2010, 01:19 PM

1st. do not take that plug out unless valve is open and bottle is empty,

and you want your gauge inline like guy above stated

ah. get a T fitting that has a female AN threads on one side and a male AN end on the other and a femal NPT thread in the middle so u can screw the gauge into it and youll be good to go.

The gauge is for the bottle heater more than anything.

http://www.clubrsx.com/graphics/00000001/82005.jpg here ya go thats the fitting

do u have a dynotune automatic bottle heater?

i could snap a pic of mine, its set up slightly different though. it has a 6an line (bigger than most standard 4an feedlines) i have a sender for the electric n2o pressure gauge and a sender for the automatic bottle heater

So whats the difference?

If the gauge is on the bottle or the line....?

98tadriver · 01-09-2010, 03:10 PM

you spend the 5-10 bux or whatever it is for that fitting and u dont have to worry about hurting yourself

LTb1ow · 01-09-2010, 03:25 PM

But whats the difference... pressure in front of the valve or behind it...

sweetbmxrider · 01-09-2010, 04:00 PM

line pressure vs bottle pressure. i believe on the bottle it may be an inaccurate reading due to the properties of liquid n20. i am no expert obviously. call up nitro daves or someone like that.

98tadriver · 01-09-2010, 08:31 PM

put it in the line and call it a day. thats how many many many many many people do it

I have may gauge in the bottle valve. I have a Harris Speed kit and thats where the directions told me to put the gauge. I like the fact that the you see your bottle pressure at all times. Think of it this way, on a hot sunny day and your bottle pressure starts getting high while the kit is not in use, You'd never know how high the bottle pressure was until you went to open the valve.

Thats what I was thinking, technically the bottle can't be open in the staging lanes too... I have a mech guage and a electric one.. so I will buy that fitting, throw the sender on that and use the mechanical gauge on the bottle itself.

the super hi flow valves NOS sell has the gauge where you inquired.
You want to be able to read bottle pressure with the valve closed, whether your heating the bottle or if the in car temps are high so you can cool it if needed.
It doesnt hurt to have both - 1 in line, 1 on the bottle.

I had an in line only from dyno tune and it was also used with the dyno tune pressure sw for the heater.
Most n2o explosions happen because of a solenoid that passes, why would you want to have your bottle open so long? You could fill your intake with n2o and not know it until you crank over the car and boom.
