Definition of Acceleration
One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows of stock cars at the Daytona 500.
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 for 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 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 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 estimated $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 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 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, all within a mere 1,320 foot long race course.
.....and that my friend, is ACCELERATION!
i thought acceleration was meters per second squared. ;)
Very nicely put, JB_OrchidGuy. My initial reaction was "Wow, this is a lot of text" but I enjoyed every word.
and yet dragracing is still boring as hell XD what a waste of horses
Nuclear pulse propulsion...
duuuuuude, thats like... the speed of light, yo :drunk:
Acceleration is popping a balloon behind a neurotic bunny. That little fur ball will fly. Hungry boa constrictors work well, too.
Lol i bet that us hear drsg speed to wireman. Funny funny.

I just thought it was interedting in email so i posted. That is a lot of feul. And the fact rhe supercharger cannot be turned with a stock hemi... Wow.

MylesG sometimes yes. I dont watch routinely. When i do it is for the wrecks or engines blowing up. But i do admit. The shear power in the engines is a bit intreaging.

i thought acceleration was meters per second squared. ;)


(ending velocity in meters per second minus inital velocity in meters per second) Divided by time (in seconds).... giving you a rate of acceleration in meters per sec.


I know, I know.... too much information

One of the best manly reads I had in a while! Thank you for sharing JB!

I read the first two lines, and immediately decided I wouldn't enjoy every word! ;)
and stopped reading..
sorry JB..

Lol....Myles if you think Drag racing is boring then I bet you LOVE Nascar hahaha.... around and around and around and around and around and around...hahaha....What I love about drag is that it's more about who can build the better car, and less about the driver( although that makes a huge difference too) and not all of the cars are almost exactly the same.

I just dont see how ppl get into nascar.....its sooooo boring hahaha....but everyone has their things :) nascar just isnt mine hahaha
