Fastest 1/4 mile ever 3.58 secs @ 386 mph (621.61 km/h)

Santa Pod dragstrip is the venue in which the current world drag racing record, a time of 3.58 seconds at 386.26 mph (621.61 km/h) was set by Sammy Miller in his Vanishing Point funny car in July 1984

The car is powered by a fuel called hydrogen peroxide which is stored in the large tank at the front of the car.

To pump the fuel to the rocket the tank is pressurised by two tanks of air - one either side of the car.

Both tanks are connected together with a pair of pipes and fed into a regulator.

The regulator keeps the pressure inside the fuel tank at a constant pressure (between 300-700 psi depending on the thrust required).

There is also a safety valve which will open if anything should over pressurise.

The fuel is then fed to the throttle valve at the back of the car, this controls the flow of fuel.

The fuel is then fed into the rocket engine

Inside the engine, the fuel is sprayed onto a silver mesh, a reaction takes place and the fuel breaks down giving off heat and water.

This produces a blast of high pressure steam & oxygen.

The engine produces about 14,000 lbs of thrust and sends the car forward at a very high speed.

In 1977 in the Mojave Desert, Kitty O'Neil piloted a hydrogen peroxide powered rocket dragster built by Ky Michaelson to the quickest quarter mile elapsed time in auto history, with a timed run of 3.22 seconds at 396 mph (637 km/h) with an average speed of 279.5 mph (449.8 km/h). This was in the desert not on a track.
