Hey, here's my issue, I installed my ZEX nitrous kit and the thing works awesome, but the other night I was drag racing and my pressure started dropping, so I flipped my heater on, let it sit 20 mins or so but the bottle didn't even start getting warm, so I thought the heater(thermostatically controlled automatically) crapped out. So I bought a new one, installed it tonight and tried it out, It immediately got warm, then the relay clicked and cooled off, then back on and off. It was cycling fairly quick and kinda erratically. On for maybe 15 seconds, off for sometimes a minute before it comes back on. After 1/2 hour, bottle not even close to feeling warm let alone hot, and the pressure 600psi(it's only about 65-70 degrees out right now) didn't even budge. I've checked my power and ground and they are good. I don't see how this can heat my bottle while I'm dragracing, the bottle gets cold just from use and I don't have 30+ minutes between rounds to get the pressure back up. I have a 10lbs bottle by the way. I did try putting the heater directly wired to a spare battery on my bench and layed the heater on the bench, turned it on and the thing got seriously hot, enough to almost burn my hand, then would kick off, and cycle back on but not as fast as when on the bottle. I'm just frustrated because I think I bought a new heater for nothing because my old one is now doing the same thing, I don't see how it will heat my bottle up, I was racing last week and it was over 80 degrees and only got 2 good runs in before my bottle pressure was down, (by the way, the bottle was full so I'm not running out of nitrous). Anyone run into this? Know what I'm talking about? Fixes? Thanks in advance!

when i was spraying my kenne bell with a 150 shot i could only get two passes out of the bottle before the pressure would fall off

try both bottle heaters and see if that will keep the pressure up longer...run them both direct to the battery...it will work better that way!

sounds like a wiring problem or the relay is bad or doesn't have enuff amps tro carry the load...who's bottle heater kit is it? I've used NOS bottle heaters in the past and never had an issue.....
