I start to tell when the bottle is gettin empty due to when letting off the gas, it kind of backfires on the deceleration or it will fall on it's face, which I am thinking it's just spraying mostly from the gas.... So, in the past, a new bottle fixed it.

But, when I fill the bottle up, it was only half empty. Any suggestions?

 

I have the same problem. I have 3-4lbs leftover when it 'stops working'..

 

When I put the nitrous plate on a month or so ago, I got the bottle to about ~900psi or so and did 2-3 WOT runs... Turned around and came back and stomped on it, and it fell on its face. Did it again, fell on its face again. So, the next day I went and got a refill (which was only half a bottle) and it hit hard like it should.

Other times it would just do a little backfiring on the decel.. So, filled bottle up and it worked fine again but was still not a full bottle that was put in..

Wonder if maybe next refill, just empty the bottle out?

 

Your suppose to re-fill the bottle at approximately 30% capacity.

 

But, with that 30% still left in, I can get the pressure up to~900 as well.. So, I guess there is no way to tell unless the car either falls on its face or backfires on the decel?


How do you tell?

 

Yes, there is a way. All you have to do is weigh the bottle. There will be weights for the bottle empty, and bottle full, on the label, or there should be. Then you just do the math and see how much you have left

 

Oh, I have never really looked at the bottle....

 

Is you line anywhere near some serious heat? I had to run my line from inside of the car threw the glove compartment gromet, after the car got hot the line wasn't to awful far from the headers, I had the same problem you had until I put the line from inside the car to the trunk.

 

I would not think so.. the bottle is in the spare tire area and the line is runing thrue the gromet area on the passenger side up and over the motor...
