Just wondering, how long does a 10lb tank of n2o last on like a 50-75shot only using it at the track on weekends for about 4-8 runs

it depends on how u use it. the longer you stay in wot the more you use. if you spray a 50hp shot in and stay in wot for 10 seconds then you might get around 26-30 uses before a refill. if you spray a 100hp shot then probably 12-15 uses before refill. of course if you stay in wot for 5 or 7 seconds then your bottle will last alot longer. in all it depends on how you use it.

You should get enough out of a 10lb for a days runs. I was running a 75bhp shot last summer with a single injector. I did get a progressive controller because of traction problems. With a controller your gas will last a lot longer.
I've just gone direct port for next summer so i'll see what happens then.

Depends on the jetting you're using. As a general rule, a 100 shot will consume 0.8 pounds of nitrous in 10 seconds. So with a 10 pound bottle, you're dry in 100 seconds, practically speaking. (Pressure drops as the bottle empties, and you should be running a pressure witch on your tank to prevent spraying at too low a bottle pressure)

So, if you're running a 50 shot, you can expect 200 seconds out of a 10 pound bottle at full pressure, and so on.
