I really don't think filling a standard feed line is going to cause that much pressure drop. A standard feed line a 14' -4 line would have about 5.27 cu/in of capacity, and a 10lb bottle is 410 cu/in. That is a very small overall percent of the bottles volume. So I don't think there would be any significant pressure drop.

Well at the end of the track on my first nitrous pass ever my bottle pressure would read 800psi. The second time I took a little more time heating it up and got it up to 1200 and let it sit for a while and drop a little to 1150, well at the end of that run it read 900 psi.
That night I asked a friend there with me that was running a 3 stage 350 shot on his car (credibility) about what was happening and he told me that my bottle if heated real quick would loose pressure fast down the track. If it was heated properly (not too fast) it would only drop about 25 psi.
I think I might join the blow torch crowd and use one of those to heat my bottle from now on. I have to run my car to keep the battery good and hot while running my electric bottle heater. Anyone got any words of wisdom?

I see conflcting opinions about having the Bottle open while heating as to heating while bottle is closed. What's the difference actually? If the pressure is there before or after...?

I just leave the bottle open all the time.

Then you open your bottle and fill the line, bingo, you just lost 100psi of pressure, but not enough to turn heater back on. Whereas, if you would have opened your line before heating, then when heater turns off your entire system is up to optimum pressure, just the way you want it. This can help you run more consistant times.

"So the bottle warmer has a timer on it almost? Or a threshold? Once it gets to a certain temp or pressure it won't turn on until a certain point?
I am thinking about getting a nitrous system within the next 3-4 months so I am trying to get all my research done now. Thanks in advance"
