Bottle Blanket

Help me out on this:
I understand the a heater blanket is recommend to keep the pressure in the bottle constant/up? If you fill the bottle to a particular PSI why does it drop if not being engaged/used? I can see some variation possible with ambient temperature changes and possibly altitude. Do I really need a blanket with a dry system? Thanks

with a dry its not as much of a problem as with a wet kit however you should still get one. Dynotune sells them on ebay fairly cheap. The kits horsepower rating is done at a certain PSI and in order to get the most out of your kit you will need to have the pressure on your bottle up. The pressure will start to drop lower when you start to use your nitrous due to it being able to expand however if its heated you will bring that pressure back up. It has saved me money in the long run because I get better usage of my nitrous bottle and can actually use it til the juice is almost gone instead of wasting 3-5 pounds of nitrous due to not having enough pressure. With a wet kit like mine you need to keep the pressure up or you will end up spraying more fuel than nitrous and flood your motor and you dont wanna finish a race and stall at the end..

Makes sense and thanks.

The bottle loses pressure besides cause it's empting due to the fact it get's cold cause of the liquid oxygen moving in it. Since your back east I'll give you a scenario to compare......

Think of a propane heater in the garage or shop that you run off a bottle like what on the BBQ. After a while on high the bottle frosts up and basicaly freezes due to the propane moving in the bottle=Same on your nitrous bottle.
Yes a blanket helps steady bottle pressure. But it also doesn't work ANY where near as good as a heater!!
Hope I helped.
