Acceleration is the change of velocity with respect to time, or the the following;
* One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500.
* Under full throttle, a dragster engine consumes 1-1/2 gallons of nitromethane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced.
* A stock 2004 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 (stoichiometry: methodology and technology by which quantities of reactants and products in chemical reactions are determined) 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 B= 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 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 $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 within a mere 1320 foot long race course.
That folks, is acceleration

Kept it up for 39 hours over the weekend, only stopping to drink champagne...

I used to have a friend who measured 'burn outs' in the street. His name was Chopper! He had a note book with locations, dates and measures of the burnt rubber... and would speculate what cars could have done it.
I also had another buddy who had the sweet 'pink panther' truck. It was a souped up S-10 and he even had the tinkle on the Ford emblem guy sticker. He was lighting it up once when we were riding dirt-bikes out to the gravel pit. He slowed down, started yelling "Buuuurrrrp, burp burp burp!" like he was on a motorcycle.
This other guy Damian asked me for years to let him buy the engine out of a used truck I had. It was a 350 bored over 30 with Harley headers, and stuff. I finally blew the rear end out of the truck yelling "Feel the Power" on a huge hill. My wife was there, and still busts me up about it.
Damian got his engine a few weeks later, after I was told how much it would cost to fix the drive train. I told them they were nuts and went to tow the truck home. They removed the pins from the rear wheels so about 3 miles down the road my rear tire passed me on the left going into a corner. The truck locked up on the ground in perfect parking position and I had a flatbead drop it off at his house.
He put the engine in a Javalin, Gremlin, and Pinto... something crazy like that and burned the tires off them in the parking lot behind McDonalds every 3 weeks or so and probably sold the engine for 5 times what I sold it to him for.

I had a 1969 Firebird HO with a compression ratio of 10 to 1.
350 w/ 300 HP, turned the quarter mile in 11.9 which wasn't bad for a stock car.
I raced a Ford Cobra on the expressway and slowly pulled away from him doing 140 mph, but unfortunately the stress was too much and the engine spun a rod bearing. Those engines weren't meant to be run wide open for any length of time.
A drag race, just like arrakis, is over in seconds.
EDIT: Hey arsekiss, didn't you just last week attempt to tell me that I had to quote my sources even though I actually had? Where did you paste this from?
