One top fuel dragster 500 cubic inch Hemi engine makes more horsepower
than the first 4 rows of stock cars at the Daytona 500.
It takes just 15/100ths of a second for all 6,000+ horsepower of an NHRA
Top Fuel dragster engine to reach the rear wheels.
Under full throttle, a dragster engine consumes 1-1/2 gallons of nitro
methane 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's supercharger.
With 3,000 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 (stoichiometry: methodology and technology by which
quantities of reactants and products in chemical reactions are
determined) 1.7:1 air/fuel mixture of nitro methane, the flame front
temperature measures 7,050 deg F.
Nitro methane 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 halfway,
the engine is dieseling from compression, plus the glow of exhaust valves
at 1,400 deg 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 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 9,500 rpm.
Assuming all the equipment is paid off, the crew worked for free, and for
once NOTHING BLOWS UP, each run costs an estimate $1,000.00 per second.
The current top fuel dragster elapsed time record is 4.428 seconds for
the quarter mile (11/12/06, Tony Schumacher, at Pomona , CA ). The top
speed record is 336.15 mph as measured over the last 66' of the run
(05/25/05 Tony Schumacher, at Hebron , OH ).
Putting all of this into perspective:
You are driving the average $140,000 Lingenfelter 'twin-turbo' powered
Corvette Z06.. 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 pass 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 1,320 foot long race course.
...... And that my friends, is ACCELERATION!

it would be close how ever. i even did the math and i shall show it. ok first you need to convert mph to feet per second formula found here (found at Conversion Factors Table) ~Miles/hour (mph) to feet/second (ft/s) (mph) * 1.466666 = (ft/s)~ soo 200mph * 1.466666 = 293.332 now 1,320/293.332 = 4.500000002 sec which is only .082 sec slower the record top fuel pass and that is saying the car will not accelerate any further in the 1/4 if the corvette were to hit the traps at 205 mph and hold it it would pass though the 1/4 mile in 4.3 sec soo it would be a good race but my money is on the vette with a 200mph head start.
