Yes so it does take a generator or some power supply.if that's not possible a simple bottle heater should work.I personally use a heat gun and generator in the pits and torch to keep temps up.imo black paint will be hotter but you need a good bit of heat to soak not only the outside of bottle but its contents. I belive 96* is all that's needed to get around 1100 psi.but just like with a torch if I heat bottle for a few secs if its completely cold the outside is to temp but the pressure hasn't risen.in other words.painting it black may have very very small advantages to keeping bottle heated but is Probally more for looks.need to look in a consistant method to heat bottle becuase that's more important
And using sunlight or exhaust does work but is keep a.close eye on pressure.maybe make a short line with guage and blow off cap so valave can stay open and you can read pressure.like I said 96* internally is around 1100 psi.no.need to.be that high on nitrous pressure unless you want it high to purge it out.900-1000 is optimal. Direct sunlight at 80* outside temp could be well over 1000* so very close eye is needed on bottle
So it seems like the black might help some, but not a whole lot...Lots of other good advice- if im understanding correctly, the bottle valve has to be open to be able to read the pressure, but obviously plugged so that im not loosing any nitrous to check it.
I thought about getting a bottle heater, but I have heard that they really put a strain on the car's battery
The bottle heaters are like headlights they pull just enough amps that if the car is off on 30 min to a hour your battery could be dead.keep the cat running or get a generator and battery charger and use that.other wise you could build a bottle bath with charcoal.and cool hotdogs at the same time.lol
good info, I guess if I keep the heater on too long then I have problems, otherwise im good....I thought I read that some shut off after reaching a certain temp, but gotta look into that more...although the charcoal and hot dogs thing sounds pretty tempting LOL
