Ya' wanna talk about poor mileage?   -Bob





Read  this thru slowly and try to comprehend the amount of  force produced 
in just under 4 seconds!  
There  are no rockets or airplanes built by any government in  the world 
that can accelerate from a standing start as  fast as a Top Fuel Dragster or 
Funny  Car! 

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 

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 friend, is  ACCELERATION!
