# One Top Fuel dragster's 500-cubic-inch Hemi engine makes more horsepower than the first four rows at the Daytona 500.

# A stock Dodge Hemi V-8 engine cannot produce enough power to drive the dragster's supercharger.

# With 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid form before ignition. Cylinders run on the verge of hydraulic lock at full throttle.

# At the stoichiometric 1.7:1 air-fuel mixture for nitro methane, the flame front temperature measures about 7000 degrees Fahrenheit.

# Nitro methane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, separated from atmospheric water vapor by the searing heat of the exhaust gases.

# Dual magnetos supply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.

# Spark plug electrodes can be totally consumed during a single pass. After half-distance, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees Fahrenheit. The engine is shut down by cutting the fuel flow.

# If a spark plug fails early in the run, un-burned nitro can build up in the affected cylinder and explode with sufficient force to blow the cylinder head off in pieces or split the cylinder block in half.

# In order to exceed 300 mph in 4.5 seconds, dragsters must accelerate at an average of more than 4 g's. In order to reach 200 mph before half-distance, the launch acceleration approaches 8 g's. A Top Fuel dragster reaches more than 300 mph before you have completed reading this sentence.

# With a redline that can be as high as 9500 rpm, Top Fuel engines turn approximately 540 revolutions from light to light. Including the burnout, the engine needs to survive only 900 revolutions under load.

# Assuming that all of the equipment is paid off, the crew works gratis, and nothing breaks, each run costs an estimated $1000 per second.

# The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter-mile (October 5, 2003, Tony Schumacher). The top-speed record is 333.25 mph as measured over the last 66 feet of the quarter-mile (November 9, 2003, Doug Kalitta).

# Putting all of this into perspective: You are driving the average $140,000 Lingenfelter twin-turbo Corvette Z06. More than a mile up the road, a Top Fuel dragster is staged and ready to launch down a measured quarter-mile as you pass. You have the advantage of a flying start. You run the Vette up through the gears and blast across the starting line and past the dragster at an honest 200 mph. The "tree" goes green for both of you at that moment. The dragster launches and starts after you. You keep your foot down, but you hear a brutal whine that sears your eardrums, and within three seconds, the dragster catches you and beats you to the finish line, a quarter-mile from where you just passed him. From a standing start, the dragster spotted you 200 mph and not only caught you but nearly blasted you off the road when he passed you within a mere 1320 feet.

Great read!

I saw something like this in a magazine article and I could not believe the low number of total revolutions the engine turns in a Top Fuel race.
Also, the 200 mph flying start comparison is unreal!

They also said that a Top Fuel dragster burns @ 10 gallons of Nitromethane in 4.5 seconds!...:eek:

If you lined up ten 1 gallon buckets of Nitromethane fuel, you could not kick them and spill them as fast as the injectors are spraying it and engine is burning it!

Top Fuel is something to behold, thats for sure. Went to my first drag race in 1969 at Barbers Point in Hawaii and saw the Snake, the Mongoose, TV Tommy Ivo and Roland Leong (all driving front engined AA/Fuelers) and all barely cracking 190 mph. Nowadays Pro Stock door slammers are faster. To me my favorite caegory were the old gasser classes but there is nothing like todays Top Fuel either. If you are along the fence when they get rolling its like getting a soft punch in the stomach as the go by.

ENGLISHTOWN NJ this week for the races! We are going down on the motorcycles and I cannot wait! Should be a great time! Nothing like going home deaf and with eyes burning from the fumes! Should be an awesome time!

Yeah, but I bet the 'Vette doesn't have a cop chip!

I also loved the old gassers. When I was a kid my Dad drag raced a 55 Chevy with one-piece flip front end, tubular front frame sections, straight axle, cutout rear fenderwells with slicks sticking out, stripped interior, and a 409 with dual quads. Enjoyed watching him line up against the Willys, Anglia, and Henry J cars with similar setups. Only thing that compares these days is the IHRA Pro-Modified class. NHRA runs a limited schedule on the Pro-Mods but it's the big draw for IHRA. Hey, guess what? IHRA still runs the 1/4 mile instead of the 1000'. I plan to go to the finals in Rockingham this October.
