what prodction engine makes the most power?

ok i am editing this post to make it more clear i kinda made it a tad confuseing before. ok which engine that goes into either a pasgner car or motorcyyle makes the most power per cubic inch.hope this made a more sence

Raggie, I would have to say this engine is most likely the most powerful in the world, and its diesel,

V10 Diesel

I dont know, an engine in which you and some of your buddies can stand inside one of the cylinders, thats quite incredible. Coming in at just under 109k HP and 5+Million ft/lb torque all at ~100RPMs.

Current production? Or historical? Power density (power per unit weight of the engine)? Probably ALL different answers, and there is a heavy "thumb" on most mfgs numbers

Historically? Probably something like the Dodge 440 cu in Hemi, but it's a BIG HEAVY engine

Then again, it might be something like the current Dodge V10 diesel. Huge HP numbers, but at LOW RPM, heavy weight, with narrow torque bands

Power density? Look at something on a motorcycle. In a CAR? Depends on if you count "exotics" as production. The McLaren F1 has some amazing hp numbers, particularly for it's weight

Non exotics? Do you count the Accura NSX as exotic? Too much cash? How about the engine in the Subaru WRX.

Non car, non passenger "production" engines, HP/Cubic inch? Probably something like the Old Fox .36 Combat special (MkIII) for U control airplanes, OR the Nelson .36 combat engine. The Fox was "off the shelf" in the hobby shops at one time, the Nelson has to be ordered. Both those engines produce in the ROUGH area of 1.25hp, weigh in around 6 oz or so. Think about those numbers - That's about 7.5 HP per cubic inch - or about 700hp for a 1.3 Liter engine if you scaled it

Non production "stock block", there have been some "interesting" engines out there - like the "ford escort" mod that was available that had the 1.3L making 900hp - of course, the engine life span was about 250-500 miles - aka one race

holly molly thats so cool.thats huge i kinda did mean hp per cubic inch though.my post was kinda confusineg.but thats one cool disel hect it would pull a person thru inntake

I think if we used certain parameters such as "per displacement" and "power production threshold" (meaning some engines can make gobs of HP but you need to rev'em to 9000rpm or whatevers and there is an utter LACK of torque down low which is "real word" power anyway) then it would HAVE to be the 2004 Mustang Mach 1! The fact I drive one has absolutely no bearing on the matter of course...

New twin turbo V-12 in the Mercedes SL65 is rated 604 HP and 738 lb-ft of torque. Probably sufficient.

The BMW Formula-1 engines of the early 80's were spec'd at 1420 HP from 1.5 litres in qualification trim. Interestingly, these were not only production based blocks, they WERE production blocks! BMW discovered that normal production engines with 20 to 30 K miles on them had 'seasoned' blocks that were stonger than new. They used to look for them in salvage yards to convert to racing engines.

Yes, I get up at 4 AM to watch F1 on Speedvision.

edit: The first post by raggie has been changed so this post has no relevance. Move along..nothin ta read here..

I think the world record holder for most powerful engine is held by GE. The GE90 (or something like that) delivers about 3.5x the power of the engine that powers an F-16 Falcon Fighter Jet. and YES it is a "production" engine. Maybe some of my fellow "erby-diddle" alumni can weigh in /ubbthreads/images/graemlins/smile.gif

But for way cool "production" engines, consider that some Formula One engines not only produce a lot of BHP, but rev to...

20,000 rpm's.

These ain't motorcycle engines. These things are amazing. F1 engines are the coolest. And the engines have to last for two race weekends now. I like NASCAR, but they ain't doing anything like this. I am impressed.

holly molly 20.000 rpm thats scary

When you say "most" you need to qualify that somehow, like in a production car, or a reciprocating engine, or what. Certainly engines in ships are very big and produce a lot of power by default. I think one of the rocket motors in the Saturn 5 rocket produces a lot of power.

Assuming you're talking about automobile engines, some of the exotics produce well over 500 hp, and I have heard of plans for one that would go near 1000 hp.

posti edited to try to be more clear

Well, in a car, the Bugatti Veyron puts out 1001 bhp and has 900 ft-lbs. of tourque.

The next generation Koenigsegg CR puts out over 1200 bhp /ubbthreads/images/graemlins/str.gif

The Honda S2000 generates 120 HP/Litre. Very close to the Veyron's 125 / Litre.

in the mid 80's BMW F1 cars had 1500hp turbo charged 1.5L engines. for those still in remedial arithmatic classes, that's 1000hp/liter folks.

Leon.

What about Mazda's rotary engine. IIRC it's horsepower to displacement ratio is/was pretty high.

at one time the ho old's quad four was tied with some ferari
engine for output per cubic inch - 1.41 hp per cubic inch

at the time these two engines put out the most hp per cubic inch of any mass produced normally aspirated engines.

and the olds aerotech(powered by a turbo charged 1100 hp quad four - 2.0 litres) held the closed course speed record for years.(might still hold the record)

but it is old tech now

my old grand am with it's stage 2 w41 ho quad four and auto trans does 0 to 60 in under 6.4 seconds - not bad for a old car.

yep mazdas my choice id love to see what they can do with it i like rotarys

The five stage 1 engines produced 160,000,000 horsepower, or 32,000,000 HP each. I got that from here. And there were enough of them made to qualify it as a production engine. I'd say it easily qualifies as the most powerful production engine to date.

BTW for those who talked about F1 engines turning at 20K - yeah, engines turning that fast are "fun" - I mentioned the Fox MKIII .36 Combat special - I have one - they detuned them after that, as the MkIII was a BIT too close to the hairy edge of coming apart - used to throw con rods! Anyway, as I said 1.25 HP in just over a 1/3rd of a cu in - of course this was at OVER 30k RPM in full out trim - I mostly ran them with a slightly larger prop to detune them - I was ONLY getting about 1hp and turning JUST over 25k rpm. Only ran them full out in matches. What was fun was these engines had NO throttle, and are normally asperated, but had external high pressure fuel feed. To start them, you'd fuel up, clamp off the fuel line, prime the engine, hook up the battery, and flip the prop. If you knew what you were doing, it'd start in the first or second flip. Now came the fun - you had to unclamp the fuel line JUST right - see, if there was too much prime left, your engine would run rich for the entire flight, unclamp too LATE and you ran out of fuel and the engine stopped. Now you'd adjust the card (hand within 3/8" of that prop that is now turning, oh, 25k rpm), but you'd leave it a TAD rich - why? Because when you let go of the airplane, the ram air intake would force a BIT more air in, so it would lean out a bit, plus it "unloaded" the prop, so the RPMs would come up another 5k or so

Mind you - no muffler, so it was "plupp, plupp (you flipping the prop), rrrrrrRRRRRRRRRRSHREEEEEEEEEEK (adjust, launch) SHREEEEEE_E_E_EK. Now in a match, the OTHER team is doing the same thing, at the same time. You both got in the air and the pilots would attempt to cut a crepe paper streamer from the back of the other airplane - more than a FEW mid airs. You were limited to .36 displacement, and like in racing, More HP = More likely to win. LOTS of effort went into eeaking out a bit more, but still being able to start it (you start the engine during the match - and there were time rules). A GOOD ground crew was IMPORTANT (2 crew, 1 pilot) Normal match fuel was 40% Nitromethane (maybe a tad more or less) 40-45% alchohol, and the rest castor oil or synthetic oil (castor is better) - aka dragster fuel with some oil added. "practice" fuel was ONLY 25% Nitro

As you can tell, these airplanes were a "tad" different than the little .049 U/C aircraft a lot of kids played with

The Fox engines are mini-marvels, very neat engineering, but they are small. Moving a "normal" size piston at those speeds takes a combination of engineering design and technological manufacturing.

And if you think the Fox engines are loud, when I was going to races a lot in my mis-spent youth (actually, pretty darn well spent, truth be known), the racing Mazda rotaries had no mufflers either. Brigeported, polished, etc. Way, way over 300 BHP out of 13A and early 13B rotaries. They'd run all day, redline was pretty much meaningless -- you'd run out of power way past the redline, and as long as you backed off as the power dropped at high rpm, it was going to hold together, and pretty easy to rebuild when you needed to. Downsides were very little low end torque -- you had to get the motor spinning pretty quick but that was no real problem, lots of heat -- even stainless steel exhausts wore out -- lots of burned feet, and LOUD! These motors were one of the reasons that there are rules on engine noise and why many racecars need mufflers. BTW, I remember 3 rotor race motors, racing rotary trucks, and 4 wheel drive rotaries. Neat stuff.

Now, for sound and power, in the 70's there was a CanAm (Canadian American) racing series, with pretty much unlimited motors. Dodge engines were bored out to (IIRC) 600+ cu. in. Monstrous horsepower. These were open cockpit cars with fenders, and by rule, had to have two seats -- but the second seat was never used and very tiny. These things cranked out so much horsepower that it could be felt through your entire body. Loud, low end rumble, and then a roar as they went by. You got your insides rattled as they approached. Later on they changed the rules and basically made the series one for older F1 cars that had fenders added to them.
