WHY IS IT SO BIG?
Like, of course a classic American sports car needs a big engine, but they're usually somewhere been a hefty 4 to 7 litres. This is well beyond that though.
This is RV engine big.
This is semi truck big.
This is WWII fighter big.
This is locamative big.
This is industrial turbine big.
This is Saturn V rocket big.
WHY IS THE ENGINE SO BIG?
It's a modernized, more batshit insane spiritual successor to the cobra. The cobra was like 7L. In a fucking tiny car. It's only fitting to have batshit insane displacement in its successor. Also
>need a big engine
>fwd land boat
Pushrod engines can't rev as high as ohc engines. In order to make power they need larger displacement. The actual size of the engine isn't all that huge. Since the cam is in the block the heads are smaller allowing the Viper to have a low hood.
Very much this. If you have the money it's really not that hard to grab a LS and put out 1000+ hp. Putting out high horsepower on an engine that will survive more than one season of track days is really hard.
The vipers engine is tuned DOWN
1) To actually solve its power delivery issues
2) Asshurt Italians
LETS not forget that dodge is owned by fiat, who also owns Ferrari. Think about how asshurt the snobs at Ferrari would be if a 100k american car BTFO the F12 Berlinetta and costs 1/4th the price? They had to preserve the status of Ferrari, just like Chebby and not letting anything progress farther than the corvette in performance.
>needing more than 645hp
what the fuck are you gonna even do with that much power
tfw: your very own custom snek is one hundred and forty one thousand dollars more than your current fun car budget.
Feels very despondent, brothers.
This. An ls/lt1 weighs less and is actually smaller than the total volume/weight of most turbo setups like the gtrs.
A dohc coyote is fuck all HUGE and its only 5 liters.
So displacement is irrelevant, especially when ohv are far more reliable, lighter, smaller
Having driven 911s and 458s I can't in all honestly say the same. Ferrari is like dating a supermodel that eats like a bird fucks like a pornstar ad doesnt say dumb shit in front of your friends, but will put a hit on you if you look at anothwr woman. Putting up with Ferraris bullshit for the privilege of driving their cars is just wprth it in a way thats almost impossible to explain.
Because anything else would be un-American.
600hp from 6 liters and 600hp from 10 liters are completely different, the torque-bands and power-bands are going to be completely different. They might produce the same hp but the bigger engine will do it at a much lower rpm's with way more torque.
tldr: stop fucking comparing just the horsepower ratings of shit.
Your crazy unstable super hot ex that fucked like a maniac, and was amazing, but you were afraid she was going to go off and stab you in the junk for something you said.
you people have never heard of cadillac eldorado? where do you live
It was so that the interior had more room without the transmission or driveshaft tunnel.
Even then it handled better than any of the previous rwd eldorados, or any cadillac of the era.
It actually has nothing to do with displacement. It's all about the cam profile, length of intake and exhaust runners, and ratio of piston bore to stroke. That's why my friend's 1.4L runs out of steam at roughly the same rpm that my 2.0L wakes up and realizes it's supposed to do something.
I'm sorry, volumetric efficiency is higher than 8L of displacement compared to a non turbo 8L. Maybe I'm saying the wrong things here, or using the wrong wording. In essence, a turbo makes up for lack of displacement by forcing more air into a cylinder to increase its power output. The volume of the CC does not change so I guess I'm looking for the volumetric efficiency...
Wut? Displacement definitely factors into a torque figure dingus. Yes, your intake/exhaust being harmonically tuned for the engine will make more hp/tq, but all a cam is going to do is change when and where the power and what kind of power is made. Look at how a cam swap can gain you a ton of HP on the top end or lots of torque down low, or a compromise of the two with a more middling pb and grind but it will not give you both. However, keep the flow numbers on the heads, the cam grind, and every other dimension identical except bore and see if you don't make more torque and hp. Larger displacement engines make more power naturally by being bigger than smalls engines because if what you said is true, a super cam and head setup will get a Nissan 5.6 V8 to the same power and torque level as a 7.0L Hemi V8.
You misunderstood my "what". The key phrase was "precision of front wheel drive".
In what back asswards world is fwd ever more precise? Where did they get off with that marketing? Was fwd just new enough that common folk still assumed new means better for science reasons?
Viper ACR would if it would have:
>2-piece 4 (6?) DOF active rear wing
>active front wing
>some kind of VVT/L
>electric motor and battery meant purely for standing in traffic jams
If you want torque, stroke it. If you want power, spin it really fast.
Displacement, cylinder count/arrangement/hippie efficiency shit, all come after the former two factors are considered.
It's not even a question.
2017 will be a sad year.
Jesus fuck that thing is pretty as all hell. I'm immensely saddened that I will probably never, ever own a Viper of any kind. It's the ultimate FUCK YOU car anyone has ever made yet has the performance to back up that FUCK YOU and make it an even bigger middle finger to the whole world.
>somehow thinking lamborghini would design a push-rod engine in todays time
>low HP per liter which europeans hate and mock
>if this engine was still in a truck or land-boat europeans would stay far away cause "lol no revs"
Sounds very un-european
Probably on from the sheer weight of the rotating assembly. It's hard to compare apples to apples because bigger engines can usually have taller or wider cylinder heads and get more optimal flow into the combustion chambers, making them more effective at gaining HP per cubic inch.
I make 775bhp without power adders on a 385 series Ford block stroked and bored to 521ci
Lambogini worked on casting the block in aluminum, removing weight from the crank, and the cooling system. All under the watch of Chrysler engineers who were working on everything else on the engine.
Needs a supercharger for maximum 'murica.
Seriously, I hope they make some kind of insane supercharged "final edition" Viper for next year with all the ACR aero and more, just so it truly goes out with the biggest fucking bang possible.
At least we gave our falcon and commadore batshit sendoffs.
Fucking do it
Holy shit found one this is amazing
displacement cucks confirmed btfo
