Drag Racing Starting Lights

Breakout - used only in handicap racing, breakout refers to a racecar running quicker than a driver predicted. The driver's prediction is called and is posted on the racecar. The driver who breaks out loses the race unless his or her opponent has committed a more serious foul, such as a red light or crossing the centerline of the drag strip.

Burnout - this is spinning the rear tires and water to heat and clean and before run for better traction. Most often the burnout precedes every rundown the drag strip.

Christmas tree - this is the electronic starting device between the lanes on the starting line. It displays a calibrated light countdown for each driver.

Elapsed time - the time it takes a drag way's vehicle to travel from the start line to the finish line.

Funny car - and aerodynamically enhanced carbon fiber body that loosely resembles the production cars on which they are based. They are supercharged, fuel injected, nitro methane burning machines and they travel the quarter mile and 4.6 seconds at more than 330 mph. Most teams use an aluminum version of the 426 Chrysler Hemi engine that produces an estimated 7000 hp.

Junior dragster - half scale version of a Top Fuel dragster designed to be driven by kids ages 8 to 17 in the NHRA Junior drag racing league. Using a 5 hp single cylinder engine, a junior dragster can go as fast as 80 mph in 7.90 seconds in the 1/8-mile.

Methanol - peer methyl alcohol used as fuel in top alcohol dragsters.

Nitro methane - May specifically as a field for drag racing and is the result of a chemical reaction between nitric acid and propane.

Nitrous oxide - when injected into an engine under pressure, this gives the engine a sudden boost in power by introducing more oxygen into the fuel mixture. Nitrous oxide is not allowed in any NHRA category except Pro Mod exhibition.

Pro stock - pro stock cars look like streetcars. They have extensive modifications to the cylinder heads, manifold, chassis and suspension thrust them to 6.6-second elapsed times at more than 205 mph. The most popular engine choices for these carbureted, gas-burning vehicles are the GM big block wedge, the Mopar Hemi and the Ford wedge.

Pro stock motorcycles - they produce more than 300 hp and are highly modified motorcycles which cover the quarter-mile in lesson 7.0 seconds at more than 195 mph. The steel chassis is cloaked in a lightweight aerodynamically enhanced replica of the original motorcycle body and the carbureted gasoline engine may be a Harley V twin or a two or four valve.

Reaction time - the time it takes the driver to react to the green starting light on the Christmas tree and it is measured in thousandths of a second. The prophet reaction time is .000.

Red light - when the racecar leaves the starting line too soon it activates the red light on the Christmas tree and the driver has automatically lost the race.

Top fuel dragster's -the fastest accelerating vehicles in the world and the most recognizable of all drag race cars. It is a 25-foot long landlocked missile, which covers the quarter mile in 4.4 seconds at speeds faster than 335 mph. The engine of choice is an aluminum version of the famous Chrysler Hemi. The supercharge, fuel injected nitro methane burning engine produces an estimated 7000 hp.
