A LONG time, I can get 5-7 track passes out of a 150 shot. Mind you that the "Hit" isnt as strong as you progress but I could still run off close times even when the bottle pressure was down after 4+ runs.

At least 5 runs getting a full hit spraying out of the hole. You could go longer but you won't get a full hit because the pressure drops as the bottle is emptied. If you're only using it in blips to stay ahead to make money then a 10lb bottle on a 75hp shot will last quite awhile. Generally, you want to always have as close to a full bottle as possible though. I always refilled mine after every trip to the spot or track. That's when multiple bottles come in handy.

How do plan on using the shot? I would guess 7-10 times then fill her up.

It's like sex with the new wife... FAST and FURIOUS through the first bottle, then it tapers off, and you hit it A LOT LESS FREQUENTLY.. so after that, it should last quite a while.

Using the estimations you guys are talkin about I am gonna have to get a much bigger bottle and a filling station at home so I dont live at the filling station.

I prob shouldent even ask cause I prob wont wanna know but how long will a 200-300 shot last using a 10lb bottle.

Realistically? Buy a couple of spares and rotate bottles. On the gas, once a week to the speed shop for nitrous refills is a regular routine.

You're right you probably shouldn't, but not for the reason you mentioned...




Given: 10 seconds = 1 lb of nitrous at a 100 shot.
We'll assume you always spray for 10 seconds with a single stage.

If 100 shot = 1 lb, then a 10 lb bottle / 1 lb per run = 10 runs

You want a 200 shot? 200 shot / 100 shot = 2
(2) (100 shot) = (1 lb used) (2) by the Distributive property.
200 shot = 2 lb used

If 200 shot = 2 lb used, then a 10 lb bottle / 2 lb per run = 5 ten second runs


Using a 300 shot? 300 shot / 100 shot = 3
(3) (100 shot) = (1 lb used) (3)
300 shot = 3 lb used
10 lb bottle / 3 lb used = 3.333333333333333333333333333333333333 ten second runs






...if you're lucky to get every last drop out of the bottle -> https://ls1tech.com/forums/showthrea...28#post4304128

That math is pretty and all, but on a 300 shot hole to trap won't last more than 2 runs. You'll still get a hit but it won't be the full 300 and your mixture will likely run rich. And you don't want to spray until the bottle empties because when there isn't nitrous along with the fuel the excess fuel will cause the car to fall on it's face. I don't use more than 5lbs out of 10lb bottle before I refill it so on a 175 shot that is roughly 4 runs hole to trap. Your setup will be more consistent using full or near full bottles.
That push system is neat looking and seems to work I guess, I haven't seen it in person or talked to anyone using it. But it would appear to be overkill on a single stage medium sized setup just to save trips to a filling station or running spare bottles.
