I was just being naughty Jere (blush) I would love to try a top fuel dragster or funny car. | ||

Nika, At one time in the blurry past, I participated in drag racing also. I ran what we called an altered roadster, ('23 Ford T-bucket fiberglass body over a full tube frame with a big block Chevrolet engine). I made the runs in the mid to high 8 second range with a top speed of roughly 165-168mph. It really is quite a thrill. The power is actually quite startling. As Tim says, the stopping (deploying the chutes) causes sudden deceleration and can be or cause eye-opening. You actually actually learn to squint for a fraction of a second just as the chutes fully deploy.. And I only traveled at 1/2 the speed and twice the elapsed time of the top fuel cars. It is indeed more fun to participate in than watch though. I really appreciate the dedication of anyone who gets involved in whatever form of motorsport they choose. I enjoyed my roughly 30 years of participating in drag racing. Been out for about six years now. Miss it. May go back. And yes, I thoroughly enjoy road racing and auto-x. | ||

Pain is all well and good, i can accept that- it's the 320mph that makes pain seem so minute, though... | ||

Driving top fuel dragsters is really hard. Its not fun at all either, its painful. ecven after the run, the pain doesnt stop. when the chute is deployed, the eyes of the driver come out of the socket because they are still moving at 320mph. | ||

Very interesting! Hey, that's my region! Anyway, us road racing guys are snobs and make fun of dragsters and oval racers, but that's some amazing facts. My spec7 has 105 HP at he rear wheels and by the time you finish this sentence I'm still trying to hit 60. | ||

This came out of the Texas Regions SCCA Newspaper 1. One fuel dragster's 500 inch hemi makes more horsepower than the first 8 rows at Daytona. 2. Under full throttle, a dragster engine consumes 1 1/2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747, but with four times the energy volume. 3. The supercharger takes more power to turn than a stock hemi makes. 4. Even with nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly solid form before ignition. Cylinders run on the verge of hydraulic lock. 5. Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder. 6. At stoichiometric(exact) 1.7:1 air/fuel mixture(for nitro), the flame front of nirtomethane measures 7050 degrees F. 7. Nitromethane burns yellow. The spectacular white flames seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gasses. 8. Spark plugs 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 shutting off its fuel supply. 9.If spark momentarily fails early in the run, unburned nitro builds up in those cylinders and then explodes with a force than can blow cylinder heads off the block in pieces or blow the block in half. 10.Dragsters twist the crank(torsionally) so far(20 degrees at the big end of the track) that sometimes cam lobes are ground offset from front to rear to rephase the valve timing somewhere closer to synchronization with the pistons. 11. To exceed 300 mph in 4.5 seconds dragsters must accelerate at an average of over 4g's. But in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8g's. 12..If all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs $1,000 per second. 13. Dragsters reach over 300 mph from a standing start before you can finish reading this sentence. Talk about extracing power and getting it to the ground. Wow!!!!!!!! |
