Definition of acceleration - 2003-04 Mach 1 Registry Owners Club

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 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!

Beautiful write up. I cant imagine 8 G's of force thats gptta be insane pressure if youre not prepared for it.

Shaker1 · 11-15-2006, 01:28 AM

Still not as powerful as a Mach with a few well chosen bolt-ons (and a good tune).

CBrowning84 · 11-15-2006, 01:41 AM

Wow! I knew they were powerful, but that blows my mind!!!

gfong · 11-15-2006, 07:15 AM

Read that before but thanks for posting. I like it!

03AV8R · 11-15-2006, 08:18 AM

Did you notice they never mentioned how much RWHP a top fueler is actually making?? I dont believe there is a system that can actually measure it.. Its over 6000 HP nowadays right?? It can be calculated by weight & ET/MPH though pretty close.. :THUMBSUP:

03AV8R · 11-15-2006, 08:23 AM

Actually using the ET & MPH #'s above they should have been making over 7000 RWHP..

Most are now estimating they make over 8000 RWHP. The HP/ET Calculator doesn't work perfectly for them because they do most of the acceleration within the first 330 feet. I've seen a more in depth write up on them. They cut sub 1 second 60 feet and are at nearly 100 MPH when they cross the 60' mark.

CBrowning84 · 11-15-2006, 10:42 AM

I think i remember reading somewhere it was around 8000HP :THUMBSUP:

G · 11-15-2006, 12:21 PM

Cool read. :THUMBSUP:

I think our cars stack up pretty well if we can make it a two way run. :ORANGE:

The acceleration theme could be continued to discuss the process of MAKING the turn-off or the tragic potentials involved with hitting something at those velocities. Driving TF sure won't get you low insurance rates. Thank God most of the time all goes well.

Amazing machines --- past and present.

Hey man, could ya pm me the name and # of that tuner? lol

I will road race a top fuel car any day and win. LOL

instantmassege · 11-15-2006, 01:48 PM

So why are we even modding our cars?!?!?

TorchMach1 · 11-15-2006, 06:30 PM

Acceleration = rate of change of velocity

JDraper · 11-15-2006, 07:05 PM

Bah..they're only fast because of all the stickers on 'em

Cool reading, thanks for posting.

HP is a measure of how fast and object moves
Torque is a measure of how far and object moves when you run into it....
