A Top Fuel dragger makes about 7,500 horsepower from about 8 litres, burning 85% nitromethane / 15% alcohol.
To add further to your reply here are some interesting facts. :)

* 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 ½ 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.

* 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 9500rpm.

* 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
333.00mph. (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 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.
That folks, is acceleration
:crazy:👍
 
Surely now with aerodynamic advances f1 cars should be allowed more horsepower as they are handling better than ever before but the stupid fia has put on aero restrictions aswell. I want to see the cars go faster.

They've undoubtedly calculated it all out, and know when things will get out of hand and unmanageably unsafe.

In fact, the limits of what the drivers can take are probably being pushed right now. Formula Ones generate insane G-forces. Any more and the drivers may not be able to last the length of a two-hour Grand Prix.

You have to remember that race cars are not remote-controlled. They are being driven by human beings. Even more important, auto racing is not a studio show, done in front of cameras only. The tracks are surrounded by huge crowds of real live people.

The limiting factor is the people involved, not the machinery.
 
I suppose it isn't that old, but here's my 20-year-old, beloved 318i...

Sitting under that hood is the same engine block that spawned the 1000+hp 1.5L Turbo 4-cylinder BMW-Brabham engine, that you guys were talking about a page ago. :sly: In qualifying-spec it could reach 1500hp, with 80+ psi of boost. :crazy:

You'd have to leave your engine block outside for a few months and piss on it occasionally to bring it upto F1 spec :sly:
