i think there was a post/debate about that a while ago

 

one run in tf dragster cost about 5g's. that's not cheap being that the motors themselves cost about 75g's.

 

What magazine did you steal that from? Car and Driver or MotorTrend? I saw that same exact thing word for word in an earlier article.

*One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows of the Daytona 500 *Under full throttle, a dragster engine consumes 11.2 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 the 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 the 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 gasses. *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. *In order to exceed 300 mph in 4.5 sec, 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 mph before you have completed reading this sentence. *Top Fuel Engines turn appr. 540 revolutions from light to light, and including the burn out, must only survive 900 revolutions under load. </TD></TR></TABLE>

I've seen a show where they were talking about TF dragsters. Somewhere it says that it has more acceleration than the NASA space shuttle from the start. Pretty amazing stuff.
