Bad refills..
Bad refills.. I'm feeling like the last 2 refills have been bad; 1-2 acceleration on the jug and after that the pressure drops substancially, like if its almost empty(500-600)! When its full, it was around 1200-1300psi usually and now its only 700-800 when freshly refilled??
They charged me for 11 and 12 lbs.
The thing that is really weird is that when I use my purge, theres no white steam, even when bottle is full, only the sound of air purging...So it really means its only air I guess!! Plus, when I disconnected my bottle, I openned the valve and a lot of air came out till there was nothing, I can tell it was NOT nitrous because my hand was right in front of the valve!
The 2 shops used pump filling system...
what you think?? How can I be sure it wont happen again?? Is it because they didnt purge the bottle before the last refills? I hate to pay 100+$ for this ****!!

The white "steam" you see is not the nitrous, it's water in the air condensing because of the low temperature of the nitrous. If it's very dry outside you won't always see much, if it's humid, you'll see more.
If you just cracked the bottle valve, which I assume you did, it will feel like it's just air.
They shouldn't purge the bottle before filling. That would be ripping you off.
Weigh the bottle right now on a reliable scale and see what it weighs.
Are you using a heater to regulate the pressure? Pressure after a fill can vary due to the temperature of the bottle. It shouldn't be between 1200 and 1300 at any time anyway. If it's a 10lb bottle, they shouldn't be putting 11 or 12lbs in it either. On a 10 pounder it should way 24.5lbs when completely full.

thanks for the reply guys, I'll check the weight before and after..
..yes I'm using a heater, but usually the pressure stays around 750 when cold and I heat it till 1000..takes 20mins. When the bottle is really empty, the pressure is around 400-600 without heatting

Isnt supposed to be very cold since its nitrogen?? Because When I purged the bottle, it was clearly not cold! My heater is working fine..
I finally got a refill and they were out of nitrous so I only got 8lbs this time. I like it better this way; I didnt get ripped this time since its under 10lbs of N2O..

I know but when they filled it with the pump system, it gets really full and the bottle warms by itself, so it shows around 1000-1200.

I'm not going back until I can afford/invest on a 9inch, which wont happen soon. I'd rather put5-6K on a stroker than a diff since its a street car.
I have found that my NX bottle (not the new bottles) weighs 25.2 lbs when full. I verified this by weighing it with the bottle nut and gauge completely empty and came up with 15.2. I used a sharpie and wrote "25.2 is full" on my bottle so there's no confusion when getting it filled.

filled the bottles too full.
When you have 11/12 lb of nitrous in a 10 lb bottle....you have
VERY small volume above the liquid. As you use the nitrous this volume increases (percentage wise) more rapidly than normal, and you see it as a faster pressure drop.
You should set up your system to operate at 1000 psig or lower and keep
bottle temperatures below 90*.
