[@xXxDeamonlordxXx]

Its always hard to compare a NA Engine to a Turbo or Supercharged Engine because the NA always lacks the Low End Power. I think the Boost takes the Lead here. More Torque, thats all. Would be fun to boost the V10 to the same Amount of Torque. Then it will smash the V8 everywhere. Or, for a better Comparison between those two, Cut the Gearing so they both have the same Speed when hitting the Rev Limiter at the same Gear. Then the higher Revs will be of Use.

[@jakesnakemate2929]

each cylinder on the v8 is bigger than one off of the v10, so even if it was na it would still have it beat in torque

[@xXxDeamonlordxXx]

@@jakesnakemate2929 Thats right, thats why you would have to shorten the gear ratio of the V10 to really even them out. The Engine Torque and RPM ard Converted in the Gearbox. If you take half of the RPM with the gear Ratio the Driveshaft Torque doubles. Easy example: if you convert 100Nm at 100RPM with a ratio of 2:1 the driveshaft will spin at 50RPM but with 200Nm.

[@banginheep]

There are some big blocks that would disagree with na always lacks low end power 😋

[@alexmills1329]

It’s a small high revving v10, it doesn’t have much low end. Compared to a larger v8, even NA gives much better low end torque, from the displacement and engine design of making power down lower since it can’t rev to 9500 rpm. At 5500 rpm making 950 hp means that car is making close to that in torque as well, which is the major difference. The v10 had very short gearing in this, but it still didn’t have enough torque to keep up.

[@GoldenCroc]

More average power is what does it, not a higher torque number.

[@guillermolopez1690]

The shape of the power curve mattered a lot more in this test than anything. V10 makes power linearly while the V8 peaks early and holds power till redline. Make both power curves linear and both results should be near identical.

[@shoryuag]

If you look at where the engines are after shifting, the V10 is well over 100hp off of peak power after a shift. The V8 is within 40 hp of peak the whole time. No wonder it's faster; more power under the curve.

[@lunarazoris41]

torque is the true magic number. less rpm = more torque, considering HP=torque x rpm/5252

[@shoryuag]

@@lunarazoris41 But if the V10 were making that V8’s torque 1500 below it’s rev limiter, do you think the V10 would accelerate just as fast as the V8?

[@lunarazoris41]

@@shoryuag yeah, without a doubt. same torque numbers is gonna mean same acceleration, but the gearing and extra rev range might help out if they have the same peak torque

[@shoryuag]

@@lunarazoris41 Please, look up and see how much power 850lbft or torque gets you at 4500rpm and how much it gets you at 8500rpm. Are you saying those two power numbers will accelerate the same weight at the same rate because the torque number is the same?

[@戴紀煬]

Every time the NA shifts to the next gear, the power drops to around 600hp. As for the supercharged V8, the power drops to around 700hp. This is what makes the difference.

[@shoryuag]

Exactly. Glad other people see this, too.

[@PapiAndrey]

Thats torque vs rpm for you. They could’ve had torque ramp up towards peak power for the V8 and the outcome would’ve been more similar. Or had the V10 make more torque before peak power. Either or, that was the main deciding factor aside from gearing

[@shoryuag]

@@PapiAndrey What you’re talking about is just changing the shape of the power curve. Gear width was the deciding factor. With closer gearing, the V10 would’ve kept up, if its average power in each gear was the same.

[@PapiAndrey]

A high revving engine would hit higher speeds more easily due to how fast it can spool up the drivetrain. Meanwhile, a low revving engine would have to work harder to reach those kinds of speeds.

I was gonna say it depends which one revs faster tbh, because climbing the peak power curve and maintaining it between gears makes a difference, and then you have an NA V10 that has much more work to do to stay in that band vs a supercharged V8 Dunno really

[@mehdiw8924]

You can clearly see that the maximum power range on the V8 is wider and its average is close to pic power. Plus the gearbox is more optimized, because is uses almost 100% of this range. This is why on the long end, the V8 pulled a big advantage.

[@robertg.3933]

This video was awesome just like all your other videos, thank you!

[@__dm__]

This is not a fair comparison. The NA engine has a flat torque band, whereas the forced induction car has a torque peak before the peak power output. The NA will have a linear power increase since the torque is roughly flat, whereas the forced induction car will have a superlinear power increase which will benefit in longer accelerations. In reality most turbo cars are tuned to have a flat torque band (some german turbo cars literally have a perfectly straight torque curve, almost like an EV), and NA engines due to the lack of fine grained control of manifold pressure like turbo cars can, have a peaky torque band. If you somehow replicated this experiment in real life, you'd get the opposite result, or whatever result you desired.

[@Varoto]

I think that you should attach a table at the end which will be comparing all scores

[@gokartninja1]

To make the same power with lower rpm, you must make more torque. Torque*RPM/5252=horsepower

[@mociczyczki]

torque is irrelevant for max acceleration what only makes diffrenc is peak power width so how % from max 750 hp both use in this egzample lowrev car use more %from peak cos have wider peak if he setup wider peak for high rev car this test would end oposit 😎 power win race 👍🏻

[@sayingnigromakesyoutubecry2647]

Should try 60 to 100 acceleration and stuff like that. That's what is important. When you come out of a curve and accelerate that's the difference in a circuit. Also, they should have different weight

[@curtharakaly4620]

Slowing down the playback speed to .25 the actual times of the tests are as follows. BLUE 0-60 in 1.959 / PINK 0-60 in 1.936----BLUE 0-100 in 4.184 / PINK 0-100 in 3.979----BLUE 0-160 in 10.638 / PINK 0-160 in 9.801----BLUE 100-200 in 16.548 / PINK 100-200 in 14.376. And as for the 60mph fuel consumption test BLUE is in 7th gear while PINK is in 5th gear for some reason which is obviously going to cause PINK to consume more fuel, as it has much more power being output from being in a lower gear causing it's rpm's to be higher than if it was in 7th gear as well.

[@IgorArkin]

There is something wrong with simulation. If two identical cars are travelling with the same speed but engine of one of them outputs more power, it would have accelerated to higher speeds. Output with a partial throttle had to be shown instead of a full throttle.

[@DAventador44]

In fairness to the V10, the V8 has almost double the torque

[@asund2424]

The results wont be the same in real life. The V10 would win the 1/4 mile. The V10 makes peak power at 9,000 rpm and the SC V8 makes peak power at 5,000 rpm. If they are geared the same and weigh the same, by the time the V10 is at 9K rpm at peak power the SC V8 is in 2nd gear and out of it power band. It would be a slinky effect resulting in the V10 winning. SC also has heat soak, and belt slip. Now a turbo could be a different result.

The real world difference I would want to know is durability. Would the high revs cause the v10 to fail much quicker?

[@Tryptamine999]

Back in the 60's or something yes the high revving motor would likely be less reliable but with modern tech that isn't guaranteed. Overall though an engine that spends it's life at 2-3K rpm will go through less abuse than an engine that spends most of its life at 7-8K rpm. But that's more on how the car is driven and not about being designed forhigh RPM use, engines like the F20c in the S2000 are very reliable and have a max rpm of 9000rpm, while there are plenty of low revving engines which are known to be unreliable. Forklift motors are so reliable because they max out at like 1-2K rpm and don't go through a lot of stress but a poorly designed motor will never be reliable no matter it's operational rpm range.

[@curtharakaly4620]

No because the low revving one has forced induction lol. Was that a serious question? If you took two engine that were exactly the same and put forced induction on one, a vast majority of the time the one with FI with fail much sooner than the Non-FI car all things being equal otherwise.

The v10 needs better gearing to match the V8 at speeds as the 8 taps into more HP at lower RPM( a word salad way of saying V8 is more torquey) You can see at 62mph, the v8 while at lower RPM are rolling on much more HP vs the V10 - 248hp vs 122hp, that should explain the performance.

Think about it this way, if you have the same gearing and power at different rpm’s, the higher revving engine will have a faster top speed because the engine is literally spinning faster in turn making everything else faster, it’s about how well it can maintain that

[@Pauli-xl8nr]

It's all about torque band and gearing ratios, torque it's the only force who's spinning car wheels, the engine power it's just equation. That V10 has less torque but can use better leverage of shorter gear ratios because it has higher rpm limit so ultimately it can match torque output to wheels compared to another engine who has higher torque but can't spin as fast. Keep in mind that engine has best acceleration near the point where torque is highest, not the power, and that torque band determines acceleration of the car when certain gear is applied.

[@detaart]

The work being done is HP, in the end that's all that matters. Torque is a static force. Think of it like putting a wrench on a nut. Imagine it's very stuck. You put more and more force (torque) on it, but it doesn't matter until it spins. When it starts spinning, you are performing work, which requires power, which in cars is expressed as HP (or more sanely in KW) HP is just a function of torque over RPM. The thing here is that while they might have the same peak HP figure, the v10 makes it up top, and it just spends very little time there. The gearing is not optimized for the delivery. The V8 doesn't need to spin as fast to make the same power, and it spends more of it's time in the power band. Area under the curve is what matters.

[@mociczyczki]

[@shoryuag]

​@@detaart You are saying the things! Nice! I'm glad people are in here that understand.

[@IgorArkin]

Talks about torque band and mechanical advantage at the same time. What a mess, check what power is beyond "it's just equation". That equation moves your car 😂

[@shoryuag]

The feeling of increasing acceleration is best as the torque number increases, then flattens out. That’s because the horsepower increase is growing so fast; if the horsepower flattens out around it’s peak, that’s where you have best acceleration, if wind resistance isn’t a factor yet. Think about it; why does every air restricted race series have race teams trying to broaden and flatten their power curves? There’s a video here on KZbin with a guy talking about the lengths NISMO went to in order to a very competitive V8 in Super GT back like 10-15 years ago.The engines are air restricted to around 500hp. So, NISMO made an engine that made 800hp at 8500 rpm and that idled at something like 4000 rpm. Why? So with a restrictor, it’d make 500 hp for as long as possible. The key part here is they were worried about the power curve, not torque. That’s the pattern, because the power is what gives you the acceleration.

[@geemy9675]

high rpm vs low rpm doesn't matter and neither does torque. it's only how wide the powerband is relative to the peak rpm (percentage not absolute rpm). also how close are the gear ratios and how quick the gear changes

[@WyFoster]

Essentially, the earlier in the rev-range that you can produce higher amounts of torque (and the longer you can sustain that torque output) is king for power production. 500bhp is 500bhp - but if you make that peak power figure at 7.5k-9k RPM - then that probably means you’re not making much power before that. It’s a game of multiplication. 5000RPM x 0 = 0. So if you have very little torque produced at high RPM then the multiplication of torque does very little. However, in a forced induction car, we can often produce more torque sooner, so if we have 3000 RPM x 100Nm then we are producing more of that peak 500bhp sooner. The simplest thing to do is to simply look at the power curve. The greater the area underneath the curve, the more power is output throughout the duration of each gear = greater acceleration. Power is a measure of the rate of change, and it already takes torque into account. 200bhp for 5 seconds leads to a greater change in work done (kinetic energy added to the car’s forward direction) than 400bhp for less than 2 seconds. Ya feel me? So if 2 cars make similar power (at similar weights), it’s usually down to which has a steeper power curve. HOWEVER - you can work around this issue with gearing. Look at the GT3 with the PDK for example. If you keep the gear ratios narrow and short, you can sacrifice some top-end in order to keep the car closer to making peak power after every up-shift, and thus you don’t suffer from the lack of low-down torque if your revs never drop.

high revving engine is very suitable for race but exhausting, while the low/mid revving engine is perfect for daily ride.. Been riding both of them, loves the speeding with high-revs but still gonna stick to low/mid revving engine, especially with abundant torque at low rpms. 👍

[@AmirGTR]

You're comparing apples and oranges. And it doesn't actually settle any debates. Try 7 liter V8 that revs to 7000rpm vs a 3.8 liter V8 that revs to 9000 RPM, both making 550hp.

[@ClownWrldUSA]

For the mpg, at 62mph, for the supercharged car you had it in 5th gear. Whereas you had the blue car in 7th gear.

[@402roadrunner]

rpm allways wins, not good compare here, they have to had same drivetrain and gearbox, than it would be good compare, and 760hp is 11-12sec car, not 9 ahhaah

[@syedusamamanzoor1838]

Wait! I don't understand how a high reving is more fuel efficient at highway speed. Shouldn't an engine spinning at 7k rpm consume more fuel than an engine spinning at 5k rpm, or is it such that a low reving engine burns more fuel per rev?

[@KB99KraYziE]

Why the 62 's consumption test, aspirated in 7th gear and charged on 5th?????

[@alwynbulik17]

Hi, what programme is this? Can you run a few tunes on the lotus emira with the 3.5L supercharge v6 engine? Increase hp/torque redline etc?

[@xx_ironman77_xx1]

The v10 is 5.0L vs an bigger v8 the bigger displacement engine not only makes more torque most of it at lower rpm’s

[@mustang5ojeff]

My only issue with this video is that during the mpg section of the video, a supercharged car will not make boost while cruising. So that’s not accurate at all.

[@chaztitan6457]

If the power curves are identical to their rpm respectively. And gearing cam be changed. Then they would be identical. Power is power

[@madxp9668]

Low rpm with that power is practically unusable for race , unles u have a extremely long gearing With the same gearing as high rpm, u will just doing burn out on every gears

[@compresant349]

The problem with doing this in beam ng is it’s too realistic and your results would probably be better if you could fix a straight line as the power curves

[@firesnake6311]

Doesn't make sense at all

[@mociczyczki]

why ? this simulation this time is correct 👌🏻

[@tomaslongoria2449]

And yet a boosted kei car with an h pattern an obnoxiously loud blow off valve or waste gate or flutter/whine is probably funner to drive.

[@RubberDuckky123]

why do you do 62 and 102mph, but you say 60 and 100mph, but with 160mph you actually go 160mph for the mpg.

[@jakobidavis2546]

In order to find hp you take the torque and rpm and run them through an equation. Ultimately the question posed here is pointless as you need more torque low end to make the same hp as a car with higher rpm.

[@roodlaargo]

id pick a v8 cuz it sounds better for me. Idk what yall see in that high pitch v10 sound but i hate it

[@robert_gasser]

Idea: 1.6NA 4 cylinder vs 1.2turbo 3 cylinder

[@1SM4h]

Probably the highest efficiency is because the V10 had smaller bore.

[@ricardodelacalle]

The v10 sounds a lot nicer? I much prefer the low RPM v8 sound.
