What is the best way to build pressure in a NOS bottle? I know they should be arond 950 to 1000 lbs of pressure. The bottle is the 125 shot deal. I have seen some people use a propane torch. That does not seem to be very wise. Any ideas how yall do it at the track?

an electronic bottle heater/blanket is the best way

Yup, they make a special bottle wrap, that keeps the bottle at the optimum tempature for use.

I have a bottle wrap. However, when the pressure is down to around 300 psi, what is the best way to heat it?

 

[Dave]

Top it off?

Top it off?

You are probably right.

If it is at 300 lbs the bottle is either empty or it is -65 degrees where the bottle is.

best way is a water heater (look at all the class racers at a big race) works much better and heats bottle all the way through.....
We use one from Jeff Prock (one of, if not the best Nitrous tuner out there)

I have run down the battery in my car before sitting in the lanes trying to get the pressure up with a blanket heater....not cool

The spas are nice but not needed for a 150 shot on a sportsman car.

I would be carefull with a propane torch! I saw a car catch on fire one time because of a propane torch (heating a bottle)
