Funny Car is a drag racing car class. Jack Chrisman (1928 &mdash August 17 1989) was an American drag racer. Marion Lee "Mickey" Thompson ( December 7, 1928 - March 16, 1988) was an American Off-road racing legend Don 'The Snake' Prudhomme, (born April 6 1941, San Fernando California) is an American Dragster racer who won the NHRA Funny Drag racing is a competition in which objects compete to be the first to cross a set finish mark usually from a dead stop and in a straight line In the USA, other "professional" classes are Top Fuel, Pro Stock, and Pro Stock Motorcycle. Top-Fuel Racing is a class of Drag racing in which the cars are run on a maximum of 90% Nitromethane and about 10% Methanol (also known as racing alcohol Pro Stock Drag Racing is a class of Drag racing featuring 'Factory Hot-Rods ' Pro Stock Motorcycle, formerly known as Pro Stock Bike is a Drag racing class that is the two-wheeled equivalent of Pro Stock. Funny cars have forward-mounted engines and carbon fiber automotive bodies over the chassis, giving them an appearance vaguely approximating manufacturers' showroom models. The Dodge Charger and Chevrolet Impala sedans are now commonly used in the NHRA. The Dodge Charger is an American Automobile manufactured by Chrysler, under the Dodge brand name The Chevrolet Impala was through 1996 a Full-sized Automobile built by General Motors for their Chevrolet division "NHRA" redirects here For other uses see NHRA (disambiguation. Worldwide, however, many different body styles are used.

Guidelines
The NHRA has strict guidelines for funny cars. Most of the rules relate to the engine. In short, the engines can only be V-8s at 90 degrees. A V8 engine is a V engine with eight cylinders mounted on the Crankcase in two banks of four cylinders in most cases set at a right angle to each other (The most popular design is loosely based on the 426 Hemi. A Hemi engine (from hemisphere) is an Internal-combustion engine in which the Combustion chambers are of hemispherical form ) There can only be two valves per cylinder and superchargers are restricted to a basic Roots type—19 inch (483 mm) rotor case length with a width of 11. A poppet valve is a Valve consisting of a hole usually round or oval and a tapered plug usually a disk shape on the end of a shaft also called a valve stem A cylinder is the central working part of a Reciprocating engine, the space in which a Piston travels A supercharger is an air compressor used for Forced induction of an Internal combustion engine. Inches redirects here To see the Les Savy Fav album see Inches. 25 inches (286 mm). The engine displacement cannot exceed 500 cubic inches (~8. Engine displacement is defined as the total Volume of air/fuel mixture an Engine can draw in during one complete engine cycle it is normally stated in Cubic 2 L). Only single camshafts are allowed. The camshaft is an apparatus often used in Piston engines to operate Poppet valves It consists of a cylindrical rod running the length of the Cylinder bank There are two common bore-stroke combinations: 4. 1875 × 4. 50 inches (106. 4 × 114. 3 mm) (called a 3/4 stroker) and 4. 25 × 4. 375 inches (108. 0 × 111. 1 mm) (called a 5/8 stroker). The 3/4 stroker is the most common combination used today and equals 496 CID (8. A cubic inch (plural cubic inches) is a non- SI unit of Volume, equal to the volume of a Cube with sides of one Inch. 1 L).
Engine blocks are usually made out of aluminum billet. WikipediaNaming Billet refers to a cast Semi finished product. It is also referred to as Ingot, particularly for smaller sizes Crankshafts are made from steel forgings. The crankshaft, sometimes casually abbreviated to crank, is the part of an Engine which translates reciprocating Linear Steel is an Alloy consisting mostly of Iron, with a Carbon content between 0 Forging is the term for shaping metal by using localized compressive forces Intake valves are titanium and of 2. Titanium (taɪˈteɪniəm is a Chemical element with the symbol Ti and Atomic number 22 40 inch (61 mm) diameter, while exhaust valves are 1. 90 inch (48 mm) diameter made out of Inconel. Inconel is a registered Trademark of Special Metals Corporation that refers to a family of Austenitic Nickel -based Superalloys Inconel Every funny car has ballistic blankets covering specific parts of the engine prone to explosion.
Funny car fuel systems are key to their immense power. Most systems will deliver from 500 to 600 psi (3 to 4 MPa) of fuel pressure at as much as 75 U. The pound per square inch or more accurately pound-force per square inch (symbol psi or lbf/in² or lbf/in²) is a unit of S. gallons per minute (62 imperial gallons/min; 5 L/s). During a single run (starting, burnout, backing up, staging, 1/4 mile) cars can burn as much as 15 U.S. gallons (12 imp gal/57 L) of fuel. US customary units, also known in the United States as English units or Imperial units (in reference to the British Empire) (but see English A gallon is a measure of Volume. It is in current use in the United States and still has limited use in many other English-speaking countries Imperial units or the Imperial system is a collection of units first defined in the British Weights and Measures Act of 1824 A gallon is a measure of Volume. It is in current use in the United States and still has limited use in many other English-speaking countries The litre or liter (see spelling differences) is a unit of Volume. The fuel mixture is usually 85–90% nitromethane with 10–15% alcohol. Nitromethane is an Organic compound with the chemical formula CH3NO2 In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon The ratio of fuel to air can be as high as 1:1. Compression ratios vary from 6:1 to 7:1. The compression ratio is a single number that can be used to predict the performance of any engine particularly piston engines (but can be used on essentially any Internal-combustion The engines in funny cars commonly exhibit varying piston heights and ratios that are determined by the piston's proximity to the air intake. A piston is a component of Reciprocating engines Pumps and Gas compressors It is located in a cylinder and is made gas-tight by Piston Funny cars have a fixed gear ratio of 3. The gear ratio is the relationship between the number of teeth on two Gears that are meshed or two Sprockets connected with a common Roller chain, or the 20:1 and have a reversing gear. Wheelbase is between 100 and 125 inches (2. In both road and rail Vehicles the wheelbase is the distance between the centers of the front and rear wheels 54 and 3. 18 m). The car must maintain a 3 inch (76 mm) ground clearance.
Horsepower claims vary widely—from 7,000–9,000—but are probably in the 8,000 BHP range. Supercharged, nitromethane-fueled motors of this type derive their extremely high speeds from their torque, which is estimated at about 7,000 ft·lbf (9,500 N·m). A torque (τ in Physics, also called a moment (of force is a pseudo- vector that measures the tendency of a force to rotate an object about They routinely achieve a 6G acceleration from a standing start. g-force (also G-force, g-load) is a measurement of an object's Acceleration expressed in g s
Safety
Many safety rules are in place to protect the driver, spectators, and others. The more visible accoutrements are the twin parachutes to help stabilize and decelerate the car after crossing the finish line. A parachute is a device used to slow the motion of an object through an atmosphere by creating drag.

Origins and name
The first funny cars were built in the mid-'60s and so-called because the rear wheels had been moved forward on the chassis to improve weight transfer under acceleration, increasing traction on the rear tires, which were oversized compared to stock. Looking at the cars, they didn't quite look stock, hence the name "funny. " Many of the older cars are still raced today in the NHRA Heritage Hot Rod Racing Series, including the National Hot Rod Reunion and the California Hot Rod Reunion.
