Top fuel dragsters are some of the most powerful machines on the planet, generating power and speed that push against the upper limits allowed by the laws of physics. This top fuel dragster quiz will amaze you with its raw power.
Although they produce astonishing amounts of horsepower, top fuel engines are based on factory 500-cubic inch Hemi engines.
GMC's diesel engine superchargers were named for the number of cylinders and the displacement of each cylinder, such as a 4:71 for a four-cylinder engine with 71 cubic inch per cylinder. More advanced superchargers got higher numbers even though the engines don't actually have 14 cylinders.
It's impossible to precisely measure a top fuel dragster's horsepower output, but estimates put it between 8,000 and 10,000.
Hill already held the quarter-mile speed record on water when he set the land record in a top fuel dragster in 1987.
Muldowney won her championships in 1977, 1980 and 1982.
Schumacher's 80 wins gives him a solid lead.
The top fuel distance was reduced to 1,000 feet from the traditional quarter-mile after the death of Scott Kalitta in 2008.
The percentage has shifted due to NHRA rule changes over the years, but as of 2016, it's 90 percent.
The NHRA first broke down its points championship into six divisions, including top fuel, in 1964. Jack Williams took the first championship.
Top fuel engines are made from aluminum.
Schumacher topped 330 mph on the quarter-mile in 1999, then did it on a 1,000-foot track in 2012.
Spencer Massey reached a speed of 332.75 mph in August of 2015.
The NHRA adjusts the minimum weight from time to time to limit speeds for safety reasons, but as of 2016 the minimum weight was 2,320 pounds.
The timing is reduced at about 7,900 rpm, which reduces top speeds slightly but helps save the engine.
In the first .5 second of a top fuel run, the driver endures more than 4 Gs of acceleration.
Nitromethane's oxygen content helps with ignition, which would otherwise be limited by the amount of air that could be forced into the cylinders.
1.2 gallons per second is faster than you can pour gasoline out of a fuel can -- the fuel system is basically a fire hose of nitromethane.
A precise measurement is hard to come by (not many sound meters can even register sounds this loud), but 150 decibels is a reliable estimate.
A dragster is just over 30 feet long.
Titanium components can sustain serious punishment, a necessity in a top fuel engine.
Including practice, qualifying and elimination rounds, $5,800 per run adds up fast.
The tires expand from a 36-inch diameter to a 44-inch diameter under the force of the wheels spinning.
Top fuel dragsters don’t have transmissions at all, just a clutch.
The supercharger is just a huge, belt-driven air pump, and it takes 700 hp to drive it (some estimates suggest it might be as high as 900 or 1,000).
A top fuel engine is rebuilt after every single run, so teams have to get it done in 30 to 40 minutes.
At 1.2 amps per spark plug, the total amperage delivered by the magnetos is not far short of an arc welder.
Special 70W racing oil keeps the engines components lubricated. It's quite a bit thicker than the 10W-30 in your street car.
The supercharger generates more than 60 psi boost pressure and shoves air into the engine at an estimated 250 mph.
It takes two spark plugs per cylinder to reliably ignite the enormous amount of fuel getting pumped into the cylinders.
250 feet of tubing is bent, angled and welded to create the rigid frame. As strong as it is, the frame isn't painted because stress cracks have to be re-welded so often.
