Today I juiced it with only 800 psi and it seemed kind of weak. My bottle might be empty but Ive only put about 7 good sprays thru it. Is 800 psi too low??

 

On a dry kit bottle pressure = flow of nitrous. So yeah...the lower the pressure the lower the HP. To compare at 900 psi on the 140 pills I got 570 rwhp. At 1200 psi it was 623 rwhp.

 

so does the bottle warmer keep track of what pressure the bottle's at or does it just keep a consistent temp? hopefully it gets hotter as more nitrous is used. correct?

 

The NX bottle heater has a pressure switch that controls the system. Works well from what Im told. As pressure drops below a set point it will turn the heater on. When the pressure rises to a certain point the heater shuts off. As the bottle empties the heater does not get hotter...just stays on longer to mainatin psi.

The rest uses a thermostat type switch to maintain a temp. Doesnt work as well ...especially when the bottle is very low. Most with this type of system bypass the thermostat and just monitor the psi via a gauge and turn off and on as necessary.
