Anyone remember the compressed air Funny Car that Mickey Thompson built?
Rocket dragsters used a lot of the same basic components as the Mickey Thompson system, such as a dome regulator, in their systems. The only real difference was instead of the compressed air being used to supercharge a piston engine it pressurized a tank to force the hydrogen peroxide into the rocket motor. A dome regulator is the type you use when you need to flow a large volume of air. In the attached page the dome regulator is the device mounted on top of the crossmember. The device to the right of the dome regulator, with the dial grip on top, is the dome loader regulator. The dome loader regulator sets the output pressure of the dome regulator.
The cool thing (no pun intended) about the Mickey Thompson system was since air was being DECOMPRESSED, it came into the intake manifold cold, thus eliminating the need for an intercooler.
