Emailed to me...Lesson in acceleration... First, some useful info:

a:) One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500.

b:) Under full throttle, a Top Fuel dragster engine consumes 11/2 gallons of nitro methane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced.

c:) A stock Dodge 426 Hemi V8 engine cannot produce enough power to drive the dragster's supercharger.

d:) 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.

e:) Cylinders run on the verge of hydraulic lock at full throttle.

f:) At the stoichiometric 1.7:1 air/fuel mixture for nitro methane the flame front temperature measures 7050 degrees F.

g:) 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.

h:) Dual magnetos supply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.

j:) Spark plug electrodes are totally consumed during a pass. After 1/2 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.

k:) 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.

l:) In order to exceed 300 mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. In order to reach 200 mph well before half-track, the launch acceleration approaches 8G's.

m:) Dragsters reach over 300 miles per hour before you have completed reading this sentence.

n:) Top Fuel Engines turn approximately 540 RPM's from light to light! This one confused Stan, but stop & ponder the fact that the engine is only used for apx 4 to 5 seconds.

p:) Including the burnout the engine must only survive 900 revolutions under load.

r:) The red-line is actually quite high at 9500 rpm.

p:) 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. The top speed record is 333.00 mph (533 km/h) as measured over the last 66' of the run.

Putting all of this into perspective:


You are riding the average $250,000 Honda MotoGP bike. 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 RC211V hard up through the gears and blast across the starting line and past the dragster at an honest 200 mph (293 ft/sec). The 'tree' goes green for both of you at that moment. The dragster launches and starts after you. You keep your wrist cranked 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. :thumb:

Yeah, this was posted a few months back, the only difference was the vehicle in the last example was a twin turbo lingenfelter Vette traveling at 200 mph instead of the GP bike.

BTW, the last example is wrong, the bike still wins the quarter! (I did the math when this was posted the last time)

Still an awesome read.

If anyone wants to know just how false some of those statements are just visit http://nitromater.com/ and search for yourself. Some of the Top Fuel guys, as in racers, along with one NHRA announcer shot holes in most of that.
Gotta register. Help a brotha out and do some research for us.

No matter how many times I read it its still amazing....Would love to feel what its like to be pushed back in your seat with 4-8g's of acceleration...yikes

Perhaps he was confused because it's wrong. /images/graemlins/smiles The "M" in RPM stands for minute--once you use that, inserting another time or distance factor to measure revolutions (such as "light to light" here) creates a conflict. What whoever wrote this meant to say is revolutions, as in (p), not RPM's.

What I think is funny is how many of the figures in each of those "facts" changes each time it's posted.

**************************************


Now another version.....

* One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 6 rows at the Daytona 500.
* Under full throttle, a dragster engine consumes 1½ gallons of nitromethane 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 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.

* 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 US $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 (or blown Viper). 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.

It is not the one I was talking about, but it does show that some things are bs in those "facts".

I'll be waiting for you here in Ohio, Gerald - V10 Nationals at Columbus and Viper Nationals in Norwalk.

BTW - I now like tequila thanks to you. :nod:
