I just bought my first Nitrous system and it comes with a 10lb bottle its a NOS system I dont think I can upgrade the bottle without paying about $250
for a new 15lb bottle and then I end up with 2 bottles but I was thinking do I need a 15lb bottle?How many runs down the1/4 can I do with the 10lb bottle?

 

depends on how fast you are. i think its around 10 sec/lb of nitrous or something like that. plus it would depend on the jet size and all that fun stuff.

 

i use 3 pounds per pass aprox.
my vett with 100 dry did 5 passes, and had 3 pounds eft!

 

Depends on how much your spraying also.

 

like 125 wet shot on 12 second passes

 

keep the pressure up and 5 passes easy

 

Thanks

 

on my Old Camaro I got 8/10 Passes out of my 10lb bottle. Pill size i was shooting was 150. That Pill should Last you allmost 50secs

 

Im thinking 125 shot is roughly 5 lbs a minute, so your looking at 2 minutes spray time on a full 10 lb bottle right?

 

So at 5lbs a minute 10lbs gets me 2 mins and thats 120 seconds and at 12 seconds passes will give me 10 passes and thats enough for a days racing I think.
Is there a gauge for sale that tells you how much you have in your bottle?

 

just dont forget, you never use all 10 pounds. 7-8 pounds, after that, your done.

 

Ok so 7 runs or so?

 

yhea, on a dry kit id say 6-8 no problem, on a wet kit, id probably want to top off around 5-7 passes. if you run low or out of spray on wet kit, you can be screwed.
