Push systems serve the same function as a regulator would, that is to help maintain a certain bottle pressure. But like regulators the concept has been around for a long time and never really taken off. There are a few different problems when trying to run a push system.

1. If you are using nitrogen to push it will dilute the nitrous in the bottle requiring you to empty and refill the bottle after every run (Although I believe Nano uses compressed air to get around this)

2. There is a lot of other equipment that is needed, bottles lines and regulators for example this can add up to as much weight or more than another nitrous bottle which can give you the same effect to a certain degree as a push system.

3. They are not legal in a lot of classes of racing

4. But the largest problem is with density. Nitrous has a certain pressure to density ratio when the pressure is had by temperature. For example at a standard pressure of 950psi the bottle will be about 90 degrees and the density of the nitrous will be 5.44 lb/gal. At 70 degrees the pressure would be about 735 and the density would be 6.45 lb/gal. What this means is that if you were to take a bottle that was 70 degrees and use a push system to artificially raise the pressure to 950 you would end up with more mass flow than you would if that pressure was brought by temperature. Now because the mass flow is increased you need to add more fuel to maintain the same nitrous to fuel ratio as you would normally have. So what you end up having to do is keep the bottles at a consistent temperature so as to avoid the large changes of density when using a push system.

So while push systems can work and the density issue doesn't change the tune up a lot until you either have a lot of nitrous or have nitrous that is fairly cold. A lot of the same benefit can be had by adding a large bottle or an extra one. If anyone has any specific questions I will try and answer them.
