"Top fuel" is the class of drag racing that uses a fuel made up of 90% nitromethane and 10% methanol(also called racing alcohol) more commonly called "nitro".

You can start at 8 years old NHRA has JR dragster classes for 8 to 17 year olds

Increase downforce which improves traction.

Top fuel dragsters have dual fuel pumps capable of pumping 77 gallons per minute. They use 22.75 gallons for warm-up, burn out, stagging and quarter mile run.

They can burn this much best the fuel Nitro methane burns at a air/ratio of 1.7:1 air fuel ratio, and most run the engine richer (1.1-1.4:1) and use the extra fuel to help cool the motor. So they run around 1.1 lbs of air to 1 lb of fuel, in an 8500rpm, 500cuin. engine running 45lbs of boost

.8 seconds 0-100mph

Yes, because the makers totally wanted little kids watching it.

They are there as an indicator so that the crew can, more easily, see how much the tires spin as the car leaves the starting line.

No, Shirley Muldowney retired in 2003 (at age 63) after a much-reduced schedule in the late 1990's.

Why we used an aerodyanamic in a ski design

Depends on the class, top fuel cost $150,000-$200,000, while a Pro stock car can be $300,000-$350,000. Maintenance is the big cost with racing.

Depending on the class, 1 or 2.

around 130-150db

ET is not affected, however, your MPH's will drop. The purpose of deep staging is to leave sooner.

Pro Stock $20,000

Any car or motorcycle that is a true "TOP FUEL" vehicle, uses a mixture of methanol (alcohol) and nitromethane. The current NHRA rules allow for a mixture of 90% nitromethane to 10% alcohol.

Dragsters are long in order to maximize stability and reduce aerodynamic drag. The length helps distribute weight evenly along the vehicle, improving traction and preventing wheelies during acceleration. Additionally, a longer body allows for a more gradual increase in speed, reducing the likelihood of losing control at high velocities.

Bull riding is more dangerous because you never know whats in the bulls mind, or in boat racing you control the boat and know if you are doing the right thing or not.

i think 4 times ..... engine explsions ....many more than he'd want to count........the last crash allmost killed him ...but the improvments in car safety saved him...thanks to Eric medlin r.i.p...........

Four and 1/4 horsepower for every 1 pound of vehicle weight. The car weighs approximately 2,100 pounds without the driver. Engine horsepower varies mostly to the conservative side, but a good figure is 8,800 horsepower hence a 4 to 1 ratio.

They use water because it helps with grip when doing burnout down drag strip, bleach would ruin the tires and track

Rear engine dragsters are more aerodynamic and provide better traction.

11,000-horsepower

The modern T/F engine is a very loose interpretation of a Chrysler engine that came out in 1951. The legendary Hemi. The first recognized "racing" derivation was the Donovan 417 of the later 60s. It was siimply an aluminum casting of a Chrysler block.

Over the next 40+ years they evolved into the modern marvels of today. Most are Mondello blocks.

The first T/F National race was won by a flat head Ford driven by Calvin Rice in

Great Bend, Kansas in 1955. He ran a sub ten second run. They tried all types, Olds, Pontiacs, Small & Big Block Chevys, but finally settled on the hemi. Its the most detonation resistant combustion chamber design. A surface area to volume thing.
