How long will the 10lb. bottle last?
This largely depends on the type of nitrous kit and jetting used. For example, a 75 HP Power Shot kit with a standard 10 lb. capacity bottle will usually offer up to 15 to 18 full quarter-mile passes. For power levels of 125 HP, 7 to 10 full quarter-mile passes may be expected. If nitrous is only used in 2nd and 3rd gears, the number of runs will be more.
