Read this recently. Especially the last two paragraphs.

TOP FUEL DRAGSTER FAST FACTS

ACCELERATION PUT INTO PERSPECTIVE

dragster* 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 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.

* A stock Dodge Hemi V8 engine cannot produce enough power to merely drive the dragster’s 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 1.7:1 air/fuel mixture for nitro methane the flame front temperature measures 7050 degrees 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 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.

* 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.

* Dragsters reach over 300 MPH before you have completed reading this sentence.

* In order to exceed 300 MPH in 4.5 seconds, dragsters must accelerate an average of over 4 G’s. In order to reach 200 MPH well before half-track, the launch acceleration approaches 8 G’s.

* 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 9500 RPM.

* THE BOTTOM LINE: Assuming all the equipment is paid off, the crew worked for free, & for once, NOTHING BLOWS UP, each run costs an estimated $1,000 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 this all into perspective:

Lets say the 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 & ready to launch down a quarter-mile strip as you pass by it. You have the advantage of a flying start. You run the ‘Vette hard up through the gears and blast across the starting line & pass the dragster at an honest 200 MPH. Just as you pass the Top Fuel Dragster the ‘tree’ goes green for both of you.

The dragster launches & starts after you. You keep your foot down hard, but you hear an incredibly brutal whine that sears your eardrums & within 3 seconds the dragster catches & 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 & not only caught, but nearly blasted you off the road when he passed you within a mere 1320 foot long race!

That’s acceleration!

I really don't see an issue with this. Not talking about the death, but the rage some people have for a kid driving these. I use to spend a lot of time at the track working with a team (adult team, not juniors). We would watch the juniors and it was awesome. There were different classes, but the highest class was an 8HP (if I remember). The times allow(age 5) couldn't be faster than 20 seconds. 5-7 was 14 seconds. 8-9 was 12 seconds. THIS IS 1/8th MILE. (my numbers could be off, its been about 10 years since I was involved).

Minivans are faster than this, so no the G Forces are not hurting the kids. The rules and restrictions are pretty darn safe. I would say motocross is MUCH more dangerous.

It's fucking crazy giving kids the reigns to that much speed, it ends in dead kids, as it has.
