Default Anybody know torque and horsepower rating of top fuel dragsters?

Just a curious question. Anybody know the torque and horsepower rating of top fuel dragsters?

Don't know the torque, but they are 8000+ HP.

I thought I read 8000 or so. Anybody know the average max torque and possibly at what rpm?

They estimate between 8,000-8,500 horsepower. There is no way to measure it.

You do realize the cost it takes to run one of those all full throttle for 3 seconds, right?

Its said that it takes 900hp to just turn the blower. You guys notice it has two separate distributors.

50-60psi from the blower? is that possible? Thats some serious boost.

In an interview, Austin Coil(Force's main man throughout the 90s when he won the majority of his championship) hinted that most of the data they had pointed at the guys with top notch equipment having just short of 10,000 hp in good air.

The TQ curve would be interesting to see but impossible to measure on any current dyno. The highest engine dyno I know of is in Jim Oddy's shop in Elma, NY and it is rated to 3000 hp. He maxes it out with his ADRL Pro Extreme screw blown hemi. Its used more for testing fuel curves and alcohol roots blown motors.

Did you ever find the missing case with $99200 left in it?

I think i read some where the torque was around 6500 something. Not exactly sure though

Enough to remove the dyno from the floor and sling it into the next county I imagine.

Here is a list of some interesting drag racing facts that I got off of a forum a few years ago. I copied in the info, for some reason I could not get the file to attach properly.




--------------------------------------------------------------------------------
* 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 Top Fuel dragster engine consumes 1 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 426 Hemi V8 engine cannot produce enough power to 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 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 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 seconds dragsters must accelerate at 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 red-line is actually quite high at 9500 rpm.

* 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. 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 all of this into perspective:

You are riding the average $250,000 Honda MotoGP bike. 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 RC211V hard up through the gears and blast across the starting line and past the dragster at an honest 200 mph (293 ft/sec). The 'tree' goes green or
both of you at that moment. The dragster launches and starts after you. You keep your wrist cranked 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.
