Ok, I have hit the switch about 3 times since I have had it. Now when I put the bottle on, it shows only 600psi. When I put the bottle heater on for about 15 mins, it only shows 800psi. Now if I am correct shouldn't I get a least 10 uses before I have to refill? It just doesn't make sense to me. I rememer the first time I used the bottle, it felt like it was leaking where the guage and line connect. Any suggestions?

you might be losing a little from somewhere. it's also a little vague in the uses department. if you use it through 4 gears from like 3k to almost red..well then you will use alot on nitrous.

Listen for leaks. You need to make sure everything is tight. Like Jeff mentioned there is no way of telling how much exactly a bottle will last you. It all depends on how long and when and where you use it. Soem bottles will last longer than others.

once bottle pressure drops down to about 600-700 that bottle is prety much dead.

That depends on the shot, too. I get about 8 good, hard 1/8th mile runs out of 12 pounds and a heater...

if there is a leak the nitrous feed line it will have frost on it.

Well it was a beautiful day out here in RI. I haven't used the Nitrous in a while (only used it 3 times). Well it was in the 80's. So I decided to see what the bottle pressure would be. It was at 900 psi. Before I could only get it to just under 800psi. Well I came to complete stop. Hit the switch and feathered first, HOLY SHIT I couldn't believe it. I felt the car pull hard. I was sooo pleased. I thought I had wasted my money. The 55 shot coupled with the S4's is insane!!!!!
