Facts and figures on BMW's F1 engine
Mind-boggling specs & information on the P83

It packs more than 900 bhp, weighs less than 90 kilograms and has a maximum engine speed of 19,200 rpm. The BMW P83 engine with which the BMW WilliamsF1 Team is pitching for the 2003 Formula One World Championship title will be put out to pasture after the final race ? the Japanese Grand Prix ? in three weeks? time.

Up to now, no more than broad skeleton data on this power pack from the Munich Formula One factory have been released. Ahead of the last two races of the season in Indianapolis (28 September) and Suzuka (12 October), its profile is now fleshed out.

Who would have guessed, for example, that 1,950 CAD drawings were made for this engine? Printed out and laid end to end, they would cover a distance of 1.3 kilometres.

Facts and figures:

· Output of the BMW P83 is over 900 bhp.

· Maximum engine speed is 19,200 rpm.

· In a race, engine speed is limited to 19,000 rpm.

· Idle speed is 4,000 rpm.

· The engine weighs less than 90 kilograms.

· It completes a distance of 500 kilometres before undergoing revision.

· Total production of the BMW P83 is 200 units, ten of which the team takes to each race.

· Before being phased out the engine will have received 1,388 upgrade modifications.

· It comprises around 5,000 individual components, 1,000 of them different.

· The air intake volume is 1,995 cubic metres per hour.

· Maximum piston acceleration is 10,000g.

· Piston speed peaks at 40 metres per second and averages 25 metres per second.

· Exhaust temperatures of up to 950 degrees are reached.

· Maximum air temperature in the pneumatic system is 250 degrees.

· The ultra-high-speed 130R turn at Suzuka with its lateral load of 4g poses the greatest challenge to the oil system.

· The BMW P83 endured the highest full-throttle proportion on the Monza circuit at 73 per cent per lap.

· At the Monaco Grand Prix, the transmission and engine have to withstand an average 3,100 gear changes.

· The engine block and cylinder head are made of cast aluminium and are manufactured at the BMW Formula One foundry in Landshut using a special thin-wall casting method.

· BMW Munich handles, among other things the manufacture of the crankshaft (steel), camshaft (case-hardened steel) and camshaft covers, as well as processing of the cylinder head and crankcase. The oil system and engine electronics also stem from BMW Munich.

BMW 83 engine timeline from concept to culmination:

· Concept: November and December 2001

· Design: January through May 2002

· Model construction at the BMW foundry in Landshut: March through May 2002

· Components manufacture: April through July 2002

· Initial assembly: July 2002

· First bench test: 31 July 2002

· Test phase development stage 1: August 2002 through January 2003

· First deployment in car: 18 September 2002

· Development to race readiness: October 2002 to mid-February 2003

· Further development: mid-February to season?s final in October 2003

In the meantime the test phase for the BMW P84 engine was launched. Following successful bench tests, it was already being tested on the track in its 2004 season specification at Monza on 4 September 2003.

TOP FUEL DRAGSTER TRIVIA

• One Top Fuel dragster's 500-inch Hemi makes more horsepower than the first 8 rows at the Daytona 500.
  
  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 4 times the energy volume.
  
  A stock hemi will not produce enough power to drive the dragster's supercharger.
  
  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.
  
  Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.
  
  At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitro methane measures 7050 degrees F.
  
  Nitro methane 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.
  
  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 those cylinders and then explodes with a force that can blow cylinder heads off the block in pieces or split the block in half.
  
  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.
  
  Dragsters reach over 300 miles per hour before you have completed reading this sentence.
  
  Top Fuel Engines turn ONLY 540 revolutions from light to light!
  
  The redline is actually quite high at 9500rpm
  
  The current Top Fuel dragster elapsed time record is 4.477 seconds for the quarter mile (06/02/01 Kenny Bernstein)
  
  
  
  Putting all of this in perspective:
  • 
    You are driving an average Lingenfelter powered "twin-turbo" Corvette. 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, but you still run the 'Vette hard up through the gears and blast across the starting line and past the dragster at an honest 200 mph. At this moment, the dragster launches and starts after you. You keep your foot hard down, but you hear an incredibly brutal whine that sears your eardrums and within seconds the dragster catches and passes you. He beats you to the finish line, a quarter mile away from where you passed him. That, folks, is acceleration.
    
    Think about it, from a standing start, this phenomenal machine has spotted you 200mph and not only caught, but nearly blasted you off the road when he passed you within a mere 1320 feet.

[StageLeft]

Impressive on both different cars, but I personally find that a 90 kilogram engine capable of 900 horsepower is totally insanely and supremely nifty.

 

[DurocShark]

Ok, I'm humbled...

 

[Demon-Xanth]

Top fuel engines pull 8000 HP and can't really be appreciated unless you watch them in person. Then you realize that those aren't engines, they're bullets.

It's probably more like 1500HP. BTW, the displacement of the BMW he's talking about is 1.5L.

 

[dnuggett]

Marvels of engineering in their own rights...

 

[Red]

I went to a Top Fuel competition in Bristol, WV this summer. I knew it was going to be fvcking crazy when I parked about 1/2 mile away and I heard the engines revving away, like some giant monster over the mountain. The loudest freaking things you've ever heard... when we went to the tents and started them up for the first time..... you can't hardly see it is so loud.... and just like that article says..when they were getting close to start time, and like 10 of the dragsters were started at one time, the air was freaking yellow... the smell of that nitro fuel makes your eyes water instantly and you cry.

It says at the bottom 900

isn't a F1 a 3L V-10 most of the times

I don't think that there are F-1 engines at the moment capable of 1500 bhp

 

[DivideBYZero]

F1 Engine = Stable Comp
Drag Engine = Liquid Nitrogen Show boat OC'er

That comparison might be true if the liquid nitrogen show boat OC'er somehow pulled off a 1000% overclock.

I've been at the drag strip and had a top fueler "pop" an engine right in front of me on the track and it feels like someone hit you in the chest with a hammer .

The dragster has 10000Hp?

Close, 8000. Give it a couple years

 

[fonzinator]

WOW! :Q That sucks that BMW engine won't be used in this Sunday's US Gran Prix. I'll be there this Sunday!

 

[geno]

Those dragster facts (Which I had seen some months ago) completely astonish me, the F1 data is cool and all, but not much surprises me, the engine weight and piston speed/acceleration numbers were cool though.

 

[sman789]

HONDA has F1 engines, its just not possible to put it in civics yet

And those engines are good for what, one or two runs before they have to be torn down and rebuilt?

 

[Demon-Xanth]

Just one. But they must be able to run within 75 minutes. (yes, a complete engine rebuild including heads takes less than 75 minute)
