And you think your car is fast.
Top fueller Urs Erbacher managed a 1/4 mile run of 318.55mph in 4.747 seconds at Santa Pod yesterday.
Now that is what I call fast.

One Top Fuel dragster 500 cubic inch Hemi engine produces more horsepower than the first 4 rows at the Daytona 500.
Under full throttle, a dragster engine consumes 1 gallon of nitromethane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced.
A stock Dodge Hemi V8 engine cannot produce enough power to drive the dragster 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 nitromethane the flame front temperature measures 7050 degrees F.
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.
Dual magnetos supply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.
Spark plug electrodes are totally consumed during a pass. After 1/2 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.
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.
In order to exceed 300 mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. In order to reach 200 mph well before half-track, the launch acceleration approaches 8G's.
Dragsters reach over 300 miles per hour before you have completed reading this sentence.
Top Fuel Engines turn approximately 540 revolutions from light to light!
Including the burnout the engine must only survive 900 revolutions under load.
The redline is actually quite high at 9500rpm.
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 US $1,000.00 per second. The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter mile (10/05/03, Tony Schumacher). 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).
Putting all of this into perspective:
You are driving the Lingenfelter "twin-turbo" powered Corvette. Over a mile up the road, a Top Fuel dragster is staged and ready to launch down a quarter mile strip as you pass. You have the advantage of a flying start. You run the 'Vette hard 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 hard, but you hear an incredibly brutal whine that sears your eardrums and within 3 seconds the dragster catches and passes you. He beats you to the finish line, a quarter mile away from where you just passed him. Think about it, from a standing start, the dragster had spotted you 200 mph and not only caught, but nearly blasted you off the road when he passed you within a mere 1320 foot long race course.
That, folks, is acceleration.

the only thing wrong with that is, thay dont use full fuel dragsters in america. only used in europe. 
but love the way you put it, makes you think your there, well kinda

Just read that a spectator was killed yesterday

I think Urs will dominate top fuel next year, speaking to some of his team on saturday night , they have set that car to run 4.7's and it ran 3 hard 4.7s at over 315mph.
Lex joons incrementals looked on target for a 4.6 on saturday if his blower didn't let go at about 1000ft still ran a 5.0 though
Heres a scary stat, on urs 4.7 sec run at the 1/8 mile he was doing 265mph in 3.2 secs ... top fuel rocks but i prefer fuel funny cars
Long live nitro and bring on flame & thunder!

Yep as Tiss said youve got to hear it to believe it, when I was growing up I lived in a village about 10 miles from the 'pod' and on a good day you could hear them going down the strip. I went many many times as I still live nearby but havent been for years but it is a great day out.

Yeh the pressure form the exhaust helps the car to stay in a straight line if you loose one then there is more force on one side and steers the car for you, i may stand corrected on this tho.
