a 10lb bottle unwarmed would last 0 passes in anyones car who actually cares about their nitrous kit's performance. A full cold bottle only gives me like 750psi which is way too low. I over-heat my bottle in a bath tub to like 1400psi then wrap it in a blanket that I just took out of the dryer before I head to the track... By the time I get there the bottle is usually around 1000psi. Between passes I keep it warm with a torch (yeah I know...) and I can easily maintain 1000psi even after several runs. I can make 4 passes through an .041 nitrous jet and only use 5.5lbs of nitrous - So thats about 40-45 seconds of use.
