How many runs on a bottle?

[jimbo98z]

I'm wondering from you guys that have nitrous, how many 1/4 or 1/8th runs do you see on a 10 lb bottle with a 125 or 150 shot. Also, how much does it cost to refill it?

get about 6-7 runs on a 150 jet, cost about $3 per lb and that is a 10lb bottle. so $30

about 5-7 depends on how much i play with the purge. and about $30.00

[jimbo98z]

is that quarter or 1/8? I assume 1/4...

[mrr23]

sorry 1/4
