crazy larry i just got through doing some reading, the jets are in the 300's in the 1/4 now.....

just not the same as a fuel car...

troy-curt When I worked for Super Chevy, the jet cars would shut down before the end of the quarter so they would not break the speed limit on the track.

And they don't even spin there tires, but they sure make your bones throb.

I havn't kept up with them for the last few years, so I'm not sure which is the fastest.

crazy larry a nitro car is faster. a jet will only get up to 260-270. nitro fueler hits 300+ if it was the mile, it might be different....

land speed record wise, the turbine has it. but don't say that around anyone who runs in a motor class.

stuartc not sure on the 747 bit? 4 jet engines i dont think they are that economical
25%less power that must be some drag car lol
if people were getting more power from a 500 cube motor surely we wouldt have jet cars
which is the faster jet car or drag car and i am thinking jet car

interesting dragster data

I got this in my email the other day, interesting info.



- Dragsters reach over 300 miles per hour before you have completed reading this sentence.

- 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 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 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.

- Top Fuel Engines turn approximately 540 revolutions from light to light!

- Including the burnout the engine must only survive 900 revolutions under load.

- 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).

- 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.

Putting all of this into perspective: You are driving the average $240,000 NASCAR Winston Cup racecar. 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 stock car 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

Troy
