Interesting little bit on dragsters.

Post by sp00n » Tue Aug 28, 2012 8:02 am

I'm not fixing the spacing, either.


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.

Seems I remember SOME of that being "fudged" (pretty sure a crewman can turn the supercharger by hand, for example), however, the "spot you a mile running start and pass you in a quarter-mile" story is 110% true.
I might be lost, IDK 🤷🏻‍♂️

Ha, I actually got it 8 years, 6 months, 2 days ago.

So does the bottom of your email speak of ET/speed records a 1-2 years before they happened?

I thought they cost way more than $4k between runs? I thought some stupid number per each piston and they replace them after each run? dunno but thought i heard something like that
