NITROUS OXIDE ( nos / n2o ) advice forum

I’ve got a Yamaha Banshee with a Yamaha R1 1000cc engine with a wet Nitrous system and it’s hot here in Missouri temp up around 100 and bottle pressure it way up, is there a way to control the pressure to the solenoid

How much bottle pressure ? At 100F I guess you are seeing around 1050 - 1100 psi ??

If this is the norm for your weather conditions then you can play with jet sizes. 850-900 psi is what I use on the heater. But I can log my AFR on the engine to fine tune. You do not need to worry about the integrity of the solenoids with this pressure. But you can play with nitrous jet sizes to fine tune on plug readings. I see no appreciable difference in AFR on a 1/4 mile pass between 800 and 900 psi on my 175 shot. If you have a concern about the extra pressure then either cool the bottle to 850 before you race by putting a wet towel onto it to bring the pressure down, or insulate the bottle to stop ambient temps making it too hot, or take your nitrous jet down by 25% and do plug readings, or add more fuel and do plug readings.
