Nitrous oxide continues to be a popular power adder for those who want to go fast. You’ll see it used on weekend warrior’s rides, bracket cars, and in the Pro Mod ranks. Getting a nitrous bottle filled can be a challenge if you don’t have a local shop that offers the service, but you can solve that issue by getting your own nitrous pump station and mother bottle.
The average cost to fill a nitrous bottle has gone well over $6 per pound in most areas. If you’re tickling your engine with a lot of giggle juice, that can add up quickly, and that is why many turn to getting their own mother bottle. To properly fill a nitrous bottle, you need a pump station and an understanding of how to use the station. We talked with Mark Wennin from Nitrous Outlet to learn more about nitrous pump stations and how to properly use them.
Nitrous pumping stations really aren’t that complex. There are just a few basic parts that make up the system, but how you use the system is what’s most important.
Nitrous Pump Station Basics
Nitrous bottles are filled using what’s called transfer filling. You’re moving the liquid nitrous from the mother bottle to the smaller bottle that’s used in the vehicle. Wennin explains how the two main ways of filling a nitrous bottle works.
“Nitrous pumps work by using compressed air to reciprocate a piston to push liquid nitrous from the mother bottle to the bottle being filled. Alternatively, you can use a gravity feed setup, which will transfer liquid nitrous from the mother bottle to the bottle being filled via pressure difference. This is accomplished thanks to a heated mother bottle and cooled bottle that’s being filled.”
The Nitrous pump stations are perfect for shops that fill a large number of bottles and want to get it done fast. Racers can also use a nitrous pump station to fill a bottle quickly at the track. A gravity feed station works in situations where you don’t need to fill a bottle in a hurry. You can also use the gravity feed station if you don’t have access to compressed air to run a traditional pump station.
Racers really can benefit from having a pumping station in their trailer or at the shop. It makes filling bottles quicker and easier when you’re pressed for time.
Now, the method you use is going to be influenced by the type of mother bottle you have. It’s very important to know if the mother bottle has a siphon tube inside.
“A siphon tube is a metal tube that runs from the valve to the bottom…
