Horsepower per cubic inch!!!!

[1st Gear]

Post on cars that were produced..Excluding tuner cars,Make sure that your post are real carz and real power plants..They have to be a production car off the assembly line.....At the manufacturer

[BobR]

1968-1970 generation Mopar 426 HEMI
425 to 700HP
426ci
~1HP to 1.64HP per CI

2003 Mopar 505
525HP (according to American Muscle Car TV)
505CI
1.03HP per CI

2001 Hennessey Dodge Viper 800
830HP
488ci
1.7HP per CI


FYI, if you only know the displacement in liters, there are ~61CI in one liter.

[1st Gear]

BOBr the 2003 doesnt count not in production no guessing cause if thats the case 2003 mustangs will have 1500hp catch my drift..Which production car from mopar came with 700hp? NOT real;Sorry bob I had to change up the question a lil not quite the right question the first time..

[dodgeram]

The Super Birds and Daytona were rated at 425 hp with the Hemi, most people in the know will tell you it was horribly underrated.

[dustin ward]

The 426 hemi will still take the cake whether its dead stock which has been dynoed at over 500hp easy or in race (called race hemi by some) trim in like a '64 polara or ramcharger. It was once said the people at the MOPAR plant that rated the 426 at 425 horsepower would have called the pacific ocean "moist"!

[E-MaxxRules]

The street legal Porsche 911 GT2 makes 462 BHP.
And the 2003 or 2004 Second Generation Viper will make 500 BHP.

[1st Gear]

Now guys this is h.p. per cubic inch.At least give ups the Liters of the engine your speakin of so we can do the figuring.I dont think it is fair to guess what someones dyno said because alot of engines that have come out over the years were sand baggin in the out put numbers so it only makes sense to use advertised #'s because my old cavalier had dynoed at 500 fwhp(no not really making a point)

[E-MaxxRules]

Fine the Second generation viper will have a 500 cu. in V-10. And the Porsche 911 GT2 has a 3.6L twin-turbo horizonally-opposed 6.

[1st Gear]

well so far emaxx rules is winning it is a production car and it has blown away the viper in the hp per cu. in.The porsche comes in a 2.1 per inch can anyone beat that??

[E-MaxxRules]

2003 Viper RT-10 here is the basic engine specs.

8.3-LITER, OHV 20-VALVE SMPI V-10
Displacement: 505 cubic inches
Compression Ratio: 9.6
Power (SAE net): 520 horsepower (est.) @ 5600 rpm
Torque (SAE net): 540 lb.-ft. (est.) @ 4600 rpm
Max Engine Speed: 6100 rpm

[1st Gear]

The viper isnt a good candadate when it comes to h.p per inch.Even the Hennesy it still has less h.p per in. then the Porsche GT2.TOO many inches to deal with.Now when it comes to torque it will be top dog im sure.

[E-MaxxRules]

1st gear, Check out this car. The McLaren F1 LM road car has a 6.1L V-12 producing 680bhp.

[1st Gear]

That car is the best ever in my opinion and man nice numbers too but it only comes with 1.8 per inch..Your GT2 is gonna be hard to beat.

[focusfrenzy]

the only thing that might beat the gt-2 porsche is the mazda rx7.
i'll see what i can find out about the hp per inch on it.

[focusfrenzy]

Ok the mazda rx7 had a 1.3 liter twin rotor rotory engine. that translates to 79 ci. and I was told that the last ones had 220 hp.
in the turbo charged version. for a 2.78 hp per ci.

I almost forgot, my brother had a 88 rx7 non turbo and it had 150hp for a hp/ci number of1.89, and if you drove like a little old lady it would get only 20m.p.g. lol
the rotory engine is the most eficiant in power produced per displacement. but they wernt very fuel eficent and were hard to get to meet emissions standards.

[E-MaxxRules]

The 2003 Mazda RX8 is powered by Mazda's revolutionary RENESIS side-exhaust rotary engine producing 250 horsepower in naturally aspirated form.

2004 Bugatti EB 16-4 Veyron:boasts an 8.0-liter W16 engine from parent VW, cranking out 1001 horsepower with four turbochargers.

[pitslayer666[]]

shelby gt500 550bhp or sumin but on gran turismo(p-station)i souped a viper with loads of money spent like 800,000 on it it puts out get ready for this 4567bhp:eek: :eek: :eek: :eek: now it has taking me a month to learn to control that car and have never ever lost one race

Thank you! See, 1st Gear, the new 505 is a real engine. Chrysler first rated it at 500HP, and about three months ago started saying 520. I'm not exaggerating... it''s been said on Speedvision, Motor Trend, Road & Track, etc.


Which production car from mopar came with 700hp? NOT real
And for the HEMI. It was in Mopar intermediates & fullsize cars from 1955 to 1971, with the 426 Wedge taking over in 1964. It was modified for more power until '72 when it was replaced with a smog-restricted 440.
As Dustin said, it was highly underrated. A few TV shows anbd magazines I've seen rate a stock HEMI at ~500 to 540HP, and a few snuck out of the factory with more radical cams that increased it to ~700HP. Only a few hi-po cam versions exist today, but since at least than 75 were made, it is considered a production engine.

I rest my case.:D

What are you talking about dude? I have like $5 million in that game and I bought every single option there is for that car (and most of the others too, plus every single one of the special models) and I didn't get anywhere close to that. I can't remember the exact numbers, but I'm sure it was like 1/4 of that number. And it wouln't win anything but the high speed oval anyway. Every time you'd tap the gas it'd do an about-face on you. I usually use the Skyline JECS (I think it was that Skyline, haven't played it in a while). I'll kill anything with my Skyline. Spent like 3 hours setting the suspension and brakes up.

[pitslayer666[]]

ok i just went on it my viper has got 3456bhp i have learnt to control that easily i beat any skyline easily and i have like $999,999,999 and it took me 3 weeks to do that:eek: :eek: :eek: :eek: but i have got other cars(78 daewoo matiz`s:confused: :confused: :confused: :confused: i didnt buy)i buy muscl only

[Fast-Traxx]

How about this!!!
Not sure what the cubic inch is on these cars but the top fuel dragsters and funny cars putting out 6000Hp Chrysler Hemi designed Keith Black engines?
I know there not production cars But I do know they should win the test on HP per cubic inches.

[43CheeriosDodgefan]

When you get smoked by a Viper in an S2000, what are you gonna say? I have more hp per ci.? The engine may make more power per cubic inch but if the cubic inch displacement isn't there you still don't have as much power.

[dustin ward]

Fast-Traxx,
Top fuel dragsters and funny cars typically run about 500 CI. This actually is fairly small for race engines but they are unbelievable in person. You would have to see one in real life up close to appreciate there power.

[Grifter2]

5.7L Camaro SS
325 H.P
I would post more info but I am not in the mood to type. Anyone care to pick up from where I left off.

[Hemihead]

BobR, I know your fairly up on the Mopar scene, but I gotta correct your dating of the Hemi's.

Chrysler built the first generation hemi's from 1951 to 1959.
331 cu in. '51-'55
354 cu in. '56
392 cu in. '57-58

The final 392's turned out about 390 horsepower in the final years of production.

There were no hemi's produced between 1960 and 1964. High performance engines included 413 and 426 'max wedge' engines with standard heads.

In 1964 they began production of the 426 hemi which continued until 1971, when emissions regulations, insurance premiums and a NASCAR ban meant the hemi had worn out it's welcome. The 425 horsepower rating was a joke. That reading is usually cited at around 4200 rpm, which is laughable considering the engine is quite capable of turning up to 7000 rpm. 500 Hp in stock form is believable.

The street hemi was an actual de-tuned racing engine. I've riden in a lot of 'fast ' cars, but my ride in a 69 Hemi Charger still takes the cake. Any car that physically prevents you from reaching out and grabbing the dashboard under acceleration is quite a machine.

[jetfan8178]

I dont remember exactly what year it was but it was a 60's version of the camaro SS that came out with a 302 that was rated between 325 to 350 hp.Thats over 1 horse per cubic inch .That thing was a rocket too.I think it did the quarter in under 14 sec'c.It was over 3500 pounds!!!

[Grifter2]

Well I know the 1969 Camaro Z 28 had a 302, but the '69 SS had the 350. So I am not sure what year your talking about.

Sure my 2001 Cobra has more hp per cu. in. then the camaro ss and the torque is very close too it is faster then the cobra by a few 10ths.Over head cams take a second to spool up.Not to mention the SS has a 6 speed.

I have to admit, you got me! I always considered the 426 Wedge to be a n early version of the latter Hemi.

[BobR]

Don't take my word for it, but I'm pretty sure those had 390ci and about 340hp in stock form.

[Grifter2]

The brand new Mustang Cobra R is faster then the Camaro SS. This is the first year that has ever happened.

[maxxwrencher]

hey jetsfan8178, the 302 camaro your are talking about is the 1969 z28 it was code named the "dz 302" because that was the engine code. ok i have a few motors to name for horse power per cubic inch. 1967 corvette stingray with the 7 liter 427 with 435 horse power. 1962 corvette with the 5.3 liter 327 with 360 horse. 1970 chevelle ls6 454 , 7.4 liters, 450 horse power that was actually closer to 500 because of its torque curve , it has 500 pound feet of torque. new chevy 4.8 liter v8 i think its a 283 ci, has 275hp. new chevy inline 6 , its a 4.2 liter with 270hp. 2002 corvette z06 , 5.7 liter, 405hp,400 pound feet of torque. new chevy big block that my dad has in his 2500 avalanche, is a 496ci, 8.1 liter, 340hp, 455 pound feet of torque. some slp trans ams sliped away from the factory with a 450hp , 5.7liter but that was in the early 90's. did i miss any??

[jetfan8178]

You missed the coolest one of all........................1991 GMC Syclone 262 4.3 liters cubic inch with 280 HP and the one that broke the land speed reconrd 4 trucks a GMC sonoma with a 5 liter V-6(I think its around 290 cubic inch)naturally aspirated at 549 HP!!

[maxxwrencher]

ya the scyclones are so sweet , pretty sweet that the can kill v8's

[SmokeDogg]

I forgot which magazine it was, but one of mine did a comparison test between a Cyclone and a Ferarri 348. It was pretty funny, about the only thing the GMC didn't whoop the 348 in was top speed, lateral acceleration, and I think maybe one other. It romped it in 0-60, 1/4 mile, slalom (I think), and beer keg capacity (yep, they actually tested that. Even put a keg in the Ferarri's front seat:D )

Bob, I don't remember what size engines those AMC's had, all I remember is how ticked off I was that an AMC embarrassed me at a stop-light. I mean, they made the PACER, for heaven's sake. All I could say was "what just happened?"

[jprophet420]

bob, you are right. it was 1970, not 71, and it was 390/360
14.4 quarter mile@101mph
0-60 in 6.4 seconds
still a contender
and almost 1bhp/cuid

[TrxDR221]

the AMC's had 304 V8's, 360 V8's, and 401 cid V8's. I just read "The Car" in autoweek. It had a 1973 AMC Javelin Pierre Cardin edition.

[jprophet420]

Taken word for word from http://www.tonyschumacher.com/dragster.shtml

[E-MaxxRules]

Sorry to burst your bubble Yippy Skippy, But a full size monster truck accelerates just as fast as top fuel dragster. If you put the power to weight ratio in to affect.

[Yippy_Skippy]

Im not going to get in a debate with you on this... Just read the facts listed above

[BobR]

Nope, they weigh many times more and "only" have about 1200HP.
Trx, I just got that issue of Autoweek. The cream-colored AMC shown is hideous, huh?
