  1. To be honest, almost all technologies get banned from F1.

  2. So you're saying Europeans, Asians, Africans, Oceanians (?) are all street drag racers? I'm European and I never launched a car, I just take it from idle.

  3. +Filipe Amaral And I guess that when only the "red" turbo is connected, the "orange" is extra mass that introduces parasitic losses.

  4. @Cousin Eddie So you're hinging on Tesla's programmers being smarter than every single hacker in the world combined. Open source displays all the vulnerabilities for the world to see. Closed source is security through obscurity.

  7. Nah, there's a real big trend of small turbo diesel engines replacing larger NA ones. Logic being that when driving carefully you get the gas mileage of a small engine, but when you need the power it's there. Most people only need it when overtaking, and the turbo is spooled by then. When electric takes over, there's no need for a NA engine.

  9. @Cousin Eddie You place your life and trust in total strangers already. What a ridiculous statement. Plus, you already trust open source - most of the internet is running on Linux. If you don't trust open source, unplug right now.

  10. @Cousin Eddie What a crappy argument. I don't need to break into anything, your VPN uses Linux servers, your email probably uses Linux servers, and if you trust ANY closed source software you're also entrusting strangers based on their loyalty to a paycheck. No matter what, unless you built your own components from scratch, wrote your own OS, run your own servers and your own internet, you're always bound to trusting strangers. And they're doing their job for public good or a paycheck. If you can't trust people to do things for good, can you even trust those who do it for money? By challenging me, you're ironically reinforcing your trust on the open source systems you rely on.

  13. ​ @sking2173  Terrible argument, considering that any glance at a history book would tell you that embracing deviancy is a tale as old as time itself, and it was the older generations who took over academia to teach such concepts in the modern iteration.

  14. @Cousin Eddie You're under-analyzing. You put implicit trust on everything you use, and all of it was designed and built by strangers. Again, breaching the car is more likely with closed source software because vulnerabilities will stay hidden. With open source, EVERYONE knows about the vulnerability so it can get patched. What do you think has more spelling mistakes? A personal journal or a published book with multiple editions?

  15. +Pingman When you pinch the end of a garden hose the water shoots out faster, right? But where does the pressure build up, in the water stream that comes out or inside the hose? Inside the hose, because a restriction will build up pressure "upstream", not "downstream". Think about those days there's an accident on the road and they close a few lanes. Before the accident there's traffic, and after the accident there's not.

  16. ozfizzy you want to maintain a balance, if your shocks have less travel to absorb the hits, you need a stiffer spring to compensate.

  18. ChiefFalque but isn't that a case-specific thing? Wouldn't the stock car designers have optimized the flow to the exhaust pulses in some cars?

  19. I think the point is that regulations would be so severe that the hyperbolic conclusion would be silent electric F1. I don't think he actually believes F1 cars are quiet.

  21.  @harleyme3163  Your cellphone is a waste of energy. First you use energy to charge the battery (with losses) then you convert the stored energy to power the phone (with losses). So it's a total loss before you even use it.

  23.  @cuda426hemi  "The idea of rights is hilarious - just look at the idiots that don't wear masks- it's their right - to kill you, right?" - You're going to wear that mask forever. When this pandemic ends, diseases caused by bacteria or viruses won't stop existing. You will continue to exhale pathogens. If you actually believe that not wearing a mask is killing people, I hope you stay true to your convictions. You will never remove that mask ever again. If you do, you're a hypocrite.

  24. Ricardo Kelm does the velocity increase? I mean, if the diameter is reduced you can increase velocity of a fluid but I'm thinking about turbines and you want pressure. And because the exhaust moves in "pulses", you do have a greater input of gasses but I don't think they design it so that the pulses "collide" in the exhaust. Basically it fills in the gaps (which still produces more work but no more pressure or velocity). The turbines aren't even that big, I have no idea how much the inertia factors in.

  25. +Jack AD the problem is that if you go to mechanical engineering, you'll get one class of this. In my country we do have "mecatronic engineering" or something but it's not recognized as an "engineering degree". Basically it's like going to law school but never do a bar exam. I have no idea if where you live you have a college degree that teaches you about cars but you have to make a choice - do you want to work on cars or do you want to be an engineer? Would you settle for a job as a car mechanic, where you'll fix cars instead of sitting through classes for years and get into debt? But if you don't want to fix cars and you want to be part of car design/engineering, will you risk getting into a degree that's only for cars when an engineering degree will allow you to work on anything, even if they only have one or two classes on car engines? The most important question: would you settle for cars as a hobby? For example, I'm in mechanical engineering and I like guns. They're not everyone's cup of tea but I'd like to work in their design and production. But I could be working on cars for a living and then have my own little machine shop where I can mess around with gun design. You could become an engineer, and for all you know you could be working on projects related to trains, ships, guns etc and make decent money that allows you to go nuts and create something yours in your garage.

  26. Then you could have an engine-driven supercharger with a clutch that disengages it after a certain number of RPM, skipping the tank entirely. AKA a twincharged engine.

  28.  @johanneshass1614  Your garage has leaks on the roof?

  29.  @johanneshass1614  You know that a light gas like hydrogen will float to the top, right? Even if your garage door is only a foot and a half from the ceiling that's still a huge amount of volume. You're the one who deserves mockery if you think a cloud of hydrogen in your ceiling is no biggie.

  32. I'm not paying attention to the visuals but if it's a comparison it's good practice to not directly call ouylt companies. Yes, you may know who they are, but that's based on your knowledge and not the presenter trying to single out anyone.

  33. You get all the exhaust "pulses" hitting the same turbine, which accelerates it faster.

  34. Billy Phillips One side is a low pressure turbine and another is a high pressure turbine, it's how we simplify calculations in steam turbines. It's the same shaft, but we partition them depending on their properties.

  35. They use a variable geometry twin scroll. It has to be 3D printed because the inside is too complex to mass produce.
    1
  36. Billy Phillips That's true, but I don't know how many twin scroll turbos are out there. I had no industry standard to compare them to, so I named a drawback. In this version, when the orange is closed off the red gets the optimal flow, but the orange side is literally dead weight. For better or worse, even the inefficient turbo for that rpm range is getting spooled in a normal twin scroll.

  37. Pistons are not kept moving by inertia alone but also from other pistons' power strokes. The less mass a piston has, the less power it steals from another.

  38. The chips that make those claims usually have multiple modes to switch from. To get more power and more fuel efficiency at the same time on an engine that was carefully designed without installing any hardware... it's baloney.

  39. Peter Vaňušanik a comment so bad you had to make it twice. This is for a LAUNCH, not grandma's groceries run. Wonder why he tested it on a highway entrance rather than a parking lot? Because he was measuring 0-60 times. If you drop the clutch on an idling motor you won't be using peak torque/hp.

  40. By that logic a jet airliner's turbines could be driven by the compressed air alone, with minimal burning of fuel just to compensate for friction losses. Or a thermoelectric powerplant could skip the gas/coal burning and have the turbine run on water pressurized by the pump, rather than steam. On a "T,s" graph the more "area" under the transformations the more work it produces. An adiabatic expansion of compressed air at near outside temperature would produce almost no work at the turbine. The objective is that the turbine outputs more work than you input at the compressing stage, that's why you need hot exhaust gas. Basically, the compressor stage and turbine stage would cancel each other, which means it would be better to have a naturally aspirated engine in the first place.

  41. CJSchecter96 making a hybrid whose target audience is the people who like hybrids the least is a good way to piss off shareholders. That's why. For starters I doubt it would appeal to those who like NA engines, they'd sooner get a turbo than electric. A "car guy" who actually needs the low end torque is probably the same kind of person who wouldn't want the weight of batteries holding back his car.

  42. +James Jones well a turbo does convert energy into mechanical work that would otherwise be wasted, that's efficiency right there. Higher intake pressures mean better atomization of the fuel particles and improves the burn characteristics of the fuel/air mixture, which means less unburnt fuel, thus a leaner mix can be used to extract the same power. That equals gas savings. This is all theoretical knowledge I got in college (mechanical engineering), but I'm scratching my head and all the engines best known for their gas mileage in the city are turbocharged diesels.

  43. Turbos work at high rpm but have trouble spooling at low rpm. The ALS counters that. By putting the turbo further down the exhaust, you'd be sacrificing "normal" regimes where the ignition isn't delayed. The turbo would be efficient when you let off the throttle but lose efficiency when you put your foot down. That's backwards.
    1
  44. Weird, I also thought about this when looking up twin turbo systems. Except it still wouldn't be feasible because one of the turbos was VGT, which in hindsight it ridiculously overkill and unnecessary.

  45. ​ @mmavcanuck Almost everything we make "can" be recycled. The problem is making sure that recycling facilities will even touch a battery built today by the time it needs to retire. I remember when having two slots for graphics cards was the rage in the computer world, because you could just buy another as a cheap upgrade. Turned out that doing it didn't make any sense, you either bought two cards at once to flex or you just upgraded to a new gen card. Every freaking time these things happen.

  46.  @WinterCharmVT  getting stuff recoated is a gamble if that coating isn't ubiquitous. Try to get a "special sauce" coating redone 10 years after being used once and discontinued and no small shop does it because they don't want to deal with the environmental regulations associated with the chemicals used. It's happening to chrome right now. Even in firearms more and more manufacturers are opting for nitrided barrels because chroming is more regulated then it used to be.

  47. ​ @ardijanuar2036  98% of industrial diamonds are lab grown, not mined. Synthetic diamonds are used in abrasives, drill bits, disc cutters for angle grinders, etc. If you ever had your teeth drilled into at the dentist, most likely a diamond tipped drill was used. Zero ethical concerns.
