how many passes can i run on a 250 shot on a 10# bottle

 

Make a run and weigh it. A full bottle weigh's 24 lbs for a referance, and I would try not to run it down lower then 2 to 3 lbs for consistancey, so if you're going thru less then 4 lbs a run you can get 2 solid runs in before you need to change it.


With a 250 shot, I am gonna guess and say you are burning thru about 2 to 2.5 lbs a run, so you "should" be able to get 3 runs out of a bottle depending on wether it was really full or not to start, and how much you purge off each run.

 

Me too, a couple runs. 1lb per 15 seconds @ 100hp shot, so a 250hp shot would take about 1.75lbs per 10.5sec run. If I had your ET I could narrow it, but an exact number, it ain't gonna happen, to many variables.

o.k., how about a 150 shot and a 9.5 second run?

 

ran 9.50 on a 150 with 800 bottle presure bumping the shot up to 250

 

I was told you'll use 1 pound of nitrous every 10 seconds for every 100HP you're spraying.

 

well my shop owner is spraying 300 and he only does 3 passes any after that we notice a dramatic drop in e.t
