Here is what I do before getting a refill. I will leave the bottle in the Freezer for couple hours so the pressure inside the bottle is lower(the shop will fill the bottle up to 900 psi regardless how many lbs). So in reality I have around 12 lbs worth of nitrous in the bottle.
The 12 lbs typically last me 5 solid passes down the 1/4 mile(spray from start to finish). I can squeeze the 6th pass if I heat the bottle up but the car tend to nose over pass the 1/8 mile mark. Hope this helps. Btw, this is on a 98 cobra with 75 shot jet setting; 150 shot on our car typically last 3-4 passes before running dry.
What!? :rolleyes:
