NHRA Facts

[cfiler]

1. One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500.

2. Under full throttle, a dragster engine consumes 1-1/2 gallons of nitromethane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced.

3. A stock 426 cu inch. Dodge Hemi V8 engine cannot produce enough power to drive the dragster supercharger.

4. 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.

5. At the stoichiometric (stoichiometry: methodology and technology by which quantities of reactants and products in chemical reactions are determined) 1.7:1 air/fuel mixture for nitromethane the flame front temperature measures 7050 degrees F.

6. Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.

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

8. Spark plug electrodes are totally consumed during a pass. After ½ way, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting the fuel flow.

9. If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinders and then explodes with sufficient force to blow cylinder heads off the block in pieces or split the block in half.

10. In order to exceed 300 mph in 4.5 seconds dragsters must accelerate an average of over 4G's. In order to reach 200 mph well before half-track, the launch acceleration approaches 8G's.

11. Dragsters reach over 300 miles per hour before you have completed reading this sentence.

12. Top Fuel Engines turn approximately 540 revolutions from light to light!

13. Including the burnout the engine must only survive 900 revolutions under load.

14. The redline is actually quite high at 9500rpm.

15. The Bottom Line; Assuming all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs an estimated $1,000.00 per second.

16. The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter mile (10/05/03, Tony Schumacher).

17. The top speed record is 333.00 mph. (533 km/h) as measured over the last 66' of the run (09/28/03 Doug Kalitta).

Thats awsome bro!! Thanx!!!

[Ammar]

WOW...incredible.

Ive grown up watching drags on tv and going to a few events as a kid. the gator nationals was quite an experience. I gotta say the top fuel cars are the most fun to watch especially at night.

There's nothing like putting it on the bumper!

Impressive!

sweet ass post!

I have a supercharged WS6 trans am with 500 rwhp, those facts make it look like a soap box racer

[LatinoPR]

nice !!!

Yikes!
