Compressed Air Supercharging has developed equipment that delivers extremely cold, dense air to the engine in an instant—and racers are getting results with it.

    Ok the article is really thin on details on how this works.

    For the layman who understands the basics of internal combustion engines. Imagine that there is no “intake” in a traditional sense, just a sealed system being fed massive but precise amounts of compressed air from a 3300 psi tank. (Its actually more complex with valves and so on so you dont use the bottle until you’re ready but lets not overcomplicate this)

    Its kind of genius because a lot of energy goes into compressing the air into the tank but that isnt energy the car needs to produce in any way which is then stored as potential energy, when you release the air from the tank its around -30c (-20f) which means a denser charge in the cylinder and therefore a bigger bang from lower boost levels.

    No mechanical drag on the engine from running a SC and no exhaust restriction from spooling a turbo, Its really clever.

    So… it’s same like Nitrous Oxide then, but instead of nitrous it’s pure oxygen now

      I don’t think so? I tthink nos is sent to the engine in the air intake. Normal turbochargers work by using the exhaust to sort of act as an air compressor and pump more air coming into the engine. Because of this turbochargers work better at higher speeds (becuase more exhaust powering the system). I think this is just kickstarting the process to engage the turbochargers earlier at lower speeds to get an edge on others. But I’m not a car guy, so I’m not actually sure.
