Anyone know roughly how much horsepower a funny car would have?(i.e. John force's car in particular) and how much top fuel dragster would have? or if someone would know where to find this info?? thanks.

top fuel, 7000 horsepower, funnycar, 6000ish, least thats what force said on driving force tv show, top fuel used to be 8000 hp, but that was before they lowered the nitro level.

I'm watching qualifying and they are talking to everyone about HP in between runs. They said 8300 was their best educated guess based on dyno numbers from Pro Stock and Alcohol cars but that may have been with the old fuel. I'm only partially paying attention. Although I'm paying enough attention to know Greg Stanfield just stole the Pro sock national record that Greg Anderson set yesterday.

Kick Ass! Go Stanfield (he is a great guy)
All Top fuel engines (Dragster/Funny car) are able to make 8k h.p.
or better. They De-tune the engines to certain track conditions.
Whats really neat is that they will mix compression ratio between
cylinders to achieve this. Both Dragster and Funny car engines are
built the same.

Before they started using the set-back blowers the difference in compression in the cylinders was crazy! I think they are a little closer to being the same now that the blowers are set back and filling the cylinders more evenly.
This has been posted before, but it gives you an idea of the power of a TopFueler, I updated some of the info
Something everybody should know:
* 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 half 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.
* When the parachutes open, the deceleration force is around -6G'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 redline is actually quite high at 8600rpm.
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 4.437 seconds for the
quarter mile (10/01/05, Tony Schumacher). The top speed record is 336.15
mph as measured over the last 66' of the run (05/25/05 Tony Schumacher).
Putting all of this into perspective:
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 and
ready to launch down a quarter mile strip as you pass. You have the
advantage of a flying start. You run the 'Vette 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.
