Default The Definition of Acceleration

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!


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.

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 load.

The redline is actually quite high at 9,500 rpm.

Assuming all the equipment is paid for, 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.

This has been posted a few times but it's always a good read. The most amazing part is John Force is one of the best driving a funny car and he is dumb as a stump. I met him once a talked for about 30 min, I thought he was working on a stand up skit on me but it's just him.

I agree this is a good thread. I went 160 once it was a blast. Unfortunatly the owner of that boat is now deceased. (boat accident) Now my 100 mph Talon is just fine. Be safe everyone!

Great article as always Matt.

My friends & I run our cats a LOT, as well as ride in each others often during the year. Even having quite a bit of regular seat time running fast, it never feels any less "serious" with each run.

The water conditions & traffic are constantly changing, so you have to be mindful of potential scenarios when you're going to run speeds that make turning more difficult. I always try to have a comfortable second option to take, if the line I'm on becomes unreliable for even the slightest reason.

I think the statistics are pretty favorable concerning accidents, when you consider how many boats are on the water capable of 90+mph. Even with what seems like every accident being posted on OSO, there aren't that many by comparison, which is obviously a great thing.

My buddy in college down in St.Pete had a 20 lake and bay boca with a 300xs engine. This was a boat that would do high 80's with nothing in front of you to block the wind. It's a flats boat so had like 0 freeboard. even less then most flats boats. It was terrifying and terrific all at the same time. At high speeds the boat would barely be in to water.

Get Real, you posted the definition of acceleration & that is something to really think about if you are reading, but if someone wants to put this into a perspective they can see one needs to go to a drag race or top fuel boat race to fully see & feel what its like as a spectator. I took a picture at firebird lake of a top fuel boat launching, I snapped the shutter when the light turned green & the picture I got was of the back side of the roostertail. 4.66 sec I believe it was unreal

Love it ! that just made the hair on my neck stand !I ve been on and around boats my whole life, fastest ive been was about 117 in my buddys fountian capsule, 170s on my rocket and grew up around flat bottom K boats, my uncle was the first in the K class to incorperate a capsule into the boats, he has lost alot of fellow friends/racers through out his raceing career, 12 years ago he retired from the boat raceing scene and started raceing Nitro funny cars, every time i go watch him , just standing 3 feet from the engine as they tune it, burping the engine, watching him go down the track, sends shivers through my body, he went from one extreme to another, id rather crash strapped in a cage then in a boat, that said i took a wave wrong on my 99 kawasaki 1100 at 75 mph , felt like i hit a brick wall !!!! broke 3 ribs,sprained my wrist and saw a chiropracter for a year, had bruises all over my body, my buddy said i looked like a rag doll floppin across the lake, i dont want to know how it feels over 100 mph

I have a steel rod in my leg from a jet ski accident that the tsa likes but thats ok. its all good . I was at havasu last year & am going again this year. It was a real trip to see a boat fly by. Of the people piloting these fast boats there.There was no problem as far as room between the boats but I do understand it only takes a second for something to go wrong. The people running those really fast boats were on their game & did an excellent job of driving I hope I get to meet some you guys in person. Maybe go for a ride??
