Most proper anti lag setups just retard timing like crazy to push the combustion into the manifold, thus spooling the turbo. whereas older anti lag setups caused intentional misfires or very sloppy timing pull causing the backfires people usually hear. That's indicative of the tune also dumping a ton of fuel, which causes excessive carbon because of the poor combustion of fuel/air mix.
To help you out, if the turbo is spinning before the car is in movement then that cuts the time the car needs to spool up rather than it having some lag when is car is moving, in result it makes the car have faster times. I hope no one else tries to bring you down due to your curiosity in learning something maybe valuable in the future.
@@Kyle17206 yes, anti-lag is when you change the timing of detonation of fuel so that it partly detonates in the cylinder and into the exhaust to spool the turbo up and then you launch and the car goes back to normal engine timing
@@joshjackburns ooh really? You sure there buddy? You sure it wasn't invented for that? It's almost like I'm joking around in my original comment, you know not being serious? Some may call it messing around others my call it joking. Now I'll admit I'm not the smartest but you mate... You're about as sharp as a bubble
I know this because i assumed people open short videos in new tabs or people who want to watch multiple videos just open them all in tabs. If I do this then I think others do this too.
This is simply stepping on the brakes/trans brake while accelerating, which builds turbo pressure before launch Antilag is a system (most commonly seen in rally cars and almost never in road cars because it destroys turbos super quickly) in which the injectors keep injecting gasoline and the timing of the spark plugs ignite it much later, causing it to ignite in the turbo, causing it to spool up. This happens when the driver let's go of the accelerator.
I’m seeing a lot of comments bashing people for not knowing what anti-lag is. Instead of making the car scene seem like a bunch of douchebags; explain it to them so they can learn to love cars just like the rest of us..... unless they like ricers
That's not anti lag... anti lag is a system for when you let off the throttle. The spark is delayed so some of the explosion escapes out the exhaust valve and into the turbo. Effectively reducing spool time and maintaining boost. What you showed an example of is a step is a multi-step system. Commonly known as "2-step" even though you could have a "4-step" system. Not bashing, just informing. Nice ride man
@loadedcoffin1945 what he is saying man ---> @@MrAsddasdasda . A delay in the combustion chamber is not antilag it's a misfire. Antilag is an injector in the exhaust manifold that fires a load to keep the turbo's pressure by keeping it spinning while the engine it's not accelerating. Another type of antilag is the F1 antilag which is an electric turbo antilag system, which can be found in Merecedes C63 AMG atm.
Since this is probably a highly custom build, this can help check for issues like fuel leaks (loss of fuel pressure) or say low air pressure (because the A/F ratio will be off).
@@lowlifemax no.. two step holds the rev limiter within specific values to provide the best launch possible Anti-lag systems basically keeps the turbos spooling when you take your foot off the gas thus preventing turbo lag which enhances the cars performing especially when shifting or braking for short periods of time
@@91hamod okay let me dumb it down for you. Why do people use „2 step“ or launch control? Exactly, to build boost so the car doesn’t have to start with turbo lag. It’s anti lag just for launching your car man. A proper 2 step or launch control also retards the ignition (the pops and bangs you hear).
Nope. I dumps fuel into the hot side of the exhaust and turbo, then ignites it. It simulates a larger displacement engine by creating more exhaust gasses. If an engine needs antilag, it isnt big enough, or it needs a smaller turbo
Because the engine "sucks" air to stay running. Easiest way to look at some of these questions is to imagine an engine as an elaborate air pump. Almost all internal combustion engines draw vacuum at idle. Typical naturally aspirated engines also create vacuum under load. Some insane high performance NA engines create very little or no vacuum, but that's a different science lesson.
Yes, problems sorted by talking with experenced mechanics, everybody saying that the turbo doesn't reach the wastegate level on neutral, when is more correct saying that turbolag usually is enough to don't leave the turbo reaching it's maximum speed before the engine
@@mattiapresti7295 Sort of, yes. What I understand as a turbo lag is the delay between throttle application and the anticipated boost level for given RPM/throttle position. When in neutral the bigger issue is that engine makes very little exhaust gasses compared to engine speed because there is almost no load on the engine. An anti lag makes the engine super inefficient on purpose, making lots of exhaust, but not much power so that it doesn't spin to the moon or pull the car too early when launching. As soon as you let go the brakes it switches back to normal operation, but now with lots of boost to produce power.
I was only trying to respond kindly. However, yes, turbolag is nothing to hard to understand. Turbocharger is not kinetically merged with the engine, and also the force that is applied on the exhaust side turbine is a function of engine's speed, together with other things. So, in other terms, this means that turbo accelerate faster as the engine's speed is, and turbo can't run if the engine doesn't
Well, actually turbolag is one of the things that I could use to say that maths is important. Because without maths becomes difficult to explain clearly, enough to say that is easier watching it in a videogame (that are mathematic reconstructions of the real world) than trying to understand it without mathematics knowledge. Literally, is ways easier to be seen than to be explained
Basically more boost = more power, the engine usually requires load to build boost ie:the weight of the car and revs of the engine. With the car in neutral there is no load on the engine so the turbo doesn't spool, antilag basically dumps fuel into the exhaust and explodes it to spin up the turbo. Tl;dr The turbo takes time to spool up, antilag makes it spool up faster from a dead stop
Is 2-step considered anti lag? Cause looks like you revving it enough until the turbo spools... also looks like you're braking the entire time so its not anti-lag as you're putting your car under load, anti-lag very noticeable when shifting(aka actually driving) since you never lose boost Idk whats going on here from the braking to the heavy breathing lmao
This guy does have anti lag, but the car is an auto. Therefore he cannot build up boost for a proper launch without otherwise doing a neutral drop. Had me confused too. Also two-step is not anti lag.
@@enemyspotted2467 ah, I've honestly never seen a straight up auto with antilag 😂 Don't automatics inherently have anti lag since the engine always underload?
