Anti Lag is epic - listen to this!
That is the sound of fuel deliberately being burnt in the exhaust, in order to keep the turbo creating boost all the time! But back in the early 2000s, Subaru took an already incredible system and stepped it up.
Creating a kind of JET ENGINE that sat in the exhaust - meaning they created MORE POWER and DOMINATED rallying at the time.
But how did this MAD contraption work?

[@DanteICE]

The supercharger and turbo charger used by Lancia wasn't during that period, it was during group B, there wasn't a restrictor during that period. They did it because they wanted mega power and big turbos were REALLY laggy back then, so the supercharger addition was to get around that problem. And from what I've seen it was mental in regards to power delivery.

I use a lot of Inconel 718 and Incololy 925. Not only does it have high heat performance, but it’s very resistant to corrosion, and it is very strong able to be age hardened to 140,000 psi MYS. It’s expensive as hell but it’s kind of a wonder metal when compared against various non Nickel steel alloys, aluminum, and even titanium options. The fact they had to use it shows the degree of engineering and performance they were after

[@gamemeister27]

Yeah it's not just the high melting point, steel also has one, but the resistance to oxygen at temperature. I hear it's also a bastard to machine.

[@adamsteinhardt6393]

@@gamemeister27 yeah, it’s very commonly used in jet and rocket engines due to the oxygen resistance at ultra high temperatures. My application is more around different corrosion mechanisms, hydrogen, chlorides, CO2 at elevated temperatures, but the airspace industry greatly impacts my ability to procure my equipment in a timely fashion largely because we are competing for Inconel

[@TheLtVoss]

Well many steel alloys without Ni or with a low content also have problems with there streng over ~ 800°C but below the liquidus they get soft gummy or brittle (or even samething in between) over the currie temperature steel losses almost all of its desired physical and chemical propertys that are needed for use applications The Jumo 004 jet engine (know from the Me262) is a great example why high temp alloys are needed the steel turbine blades just couldn't cope long in a hot exaust stream because of streng and Oxidation problems (well they increased the life time of the engines massively by ceramic coating the blades but the core problem was the leak of alloy materials therfore the almost milled steel blades)

[@DOMO1785]

I would be amazed if there were, but are there any additive manufacturing processes for Inconel? Actual photos of the “rocket” seem like it was welded together from various pieces of bent/machined parts, but this would be a helluva lot easier to make with atomized powder and lasers

[@gamemeister27]

@@DOMO1785 So I googled it, and first result is from protolabs. Not only can you use it for 3d metal printing (sintering like you said), but you can have them print parts for you out of Inconel 718.

[@rickj6348]

Its pretty neat how Subaru basically took the combustion chamber from an older turbine engine and created this monster. Incredible!

[@dimitryjeanpierre]

Head gasket go brrrr

[@Thri11seeker]

It already ate head gaskets but this allows them to eat through head gaskets faster which meant that their turbo was able to get their own source of cooling because coolant would escape from the exhaust and evaporate on the turbo

[@Umar-gw6fy]

MLS head gaskets have entered the chat

[@Giuliana-w1f]

Actually, this would lower the combustion chamber pressures, since the air fuel mixture ignites outside of the cylinder instead of with the spark plug (i've also heard that the head gasket issues are mostly on the USDM 2.5L, not as much the 2.0L, but i'm not sure about that)

[@Awkward_Fox]

​@@Giuliana-w1fYou would be correct about the 2.5 litres (EJ25X) having head gasket problems. The 2 litre (EJ20) just has thicker cylinder walls and therefore a better clamping surface for the gaskets. The naturally aspirated EJ25 were the ones with major problems because of the single layer head gaskets that were used. Turbo EJ25s used MLS gaskets which, at stock power, are pretty reliable for 1-200k miles if taken care of!

[@nigeldepledge3790]

One of the difficulties of the group B cars was the immense turbo lag that came with the huge turbochargers they used. You'd plant your foot on the throttle, then wait a second or so while the engine tried to get the turbo spinning. And then you'd suddenly have more torque than you knew what to do with. The other major problem was that you were driving the same stages with 400+ hp that you drove the previous year with under 150 hp.

[@EritoKaio]

Inconel is very commonly used for actual rocket engines, that's crazy.

[@bjones7188]

i remember the day my then 62ish year old mother heard anti-lag for the first time, she legit thought someone was firing a machine gun, me on the other hand was laughing my ass off cause i knew what it was and where it was coming from.

[@joshlewis5065]

Turbosmart has a ALS valve that you can install to your turbo system. It takes your pressurized air frok your charge pipes and routes it directly to your exhaust header. Run a rich 0% throttle map with late spark timing, and now you have anti lag.

[@jfess1911]

The rocket exhaust is related to NOx reduction burners used in industry. The goal is to get complete combustion yet lower the overall temperature of the mix. It's essentially a way to get combustion in overly lean conditions.

[@ApothecaryTerry]

[@artoodiitoo]

probably a topic for another video? :D

[@hayzeproductions7093]

4:58 The in car video view was from an setup called "Fresh Air" anti lag system which operated very differently. The throttle would be fully closed, but the turbo would keep spinning and never spin down until you flip a switch. Basically your plumbing a T into the charge pipe right before the throttle body to a waste gate that's plumbed to each individual exhaust port on the exhaust manifold feeding itself to keep the turbo spinning from the exhaust side. From watching videos about it in the past. Rally Racing banned this type of technology and a new type of technology "Rocket Anti-lag" came into place for a more efficient design from an emissions standpoint.

[@butwhytharum]

thats pretty ingenious turning the turbo into a jet turbine for anti lag and not killing the turbo at the same time by keeping the combustion steady.

[@gringostarr69]

[@TundeEszlari]

[@AmirPomen]

U forgot telling the part that this rocket anti-lag main advantage over conventional antilag.. That would be full boost even at idle speed engine rpm... Thats why subaru impreza s12b code chassis can start-launch at rally stages just sitting idle... As opposed to conventional antilag needing the driver to input 100% throttle and keep the engine rev high enough to start/launch...where then whem only after get moving, the conventional antilag will be effective...as the engine rpm relatively kept at reasonably high rpm to get the exhaust gas moving decently... Rocket antilag can be driven in more relaxed manner at launch as well as at every type of corner without needing to keep the engine rpm high enough...because there is already full boost available even from idle rpm...solving problems of bogging down at super tight hairpins or driver error... Less driver stress on keeping the engine rpm as high meams less engine wear, less drivetrain shock, more focussed driver and cleaner driving style...more potential to wins... I wonder what the result would be if Seb.Loeb given the chance to compete in wrc driving this version of subaru...

[@timlash]

I'd love to see a rally video on the job of the navigator. What are they saying? What does it mean? How does it help the driver? I never understood any of that.

[@gamemeister27]

I think they have course layouts on their paper and they inform the driver of upcoming turns. They're on public roads and aren't doing laps, so the drivers can't possibly memorize the "course" beforehand.

[@kleanish]

There are tons of videos on this

[@adamcichon6957]

It's a code/language of commands, that describes: angle of the turn, it's lenght, distances between the turns or way points, on witch side of the road should they be before the next turn, state of the surface, what obstacles are ahead (like chicanes, jumps, dips and hills, creek crossings, and so on and do forth), which amount on or off throttle driver should be in a particular turn. Driver dictates those commands to the co-pilot at the mandatory and strictly regulated route reconnaissance, before the main rally event. Than, after the start of the rally, co-pilot just reads those commands for the driver. It's like driving in fog with the GPS on. You see on screen, in advance the turns of the road, before you reach them. Same with those commands, but very much the analog way of doing the thing.

[@RightLadd]

Typically they will use a system such as a 1-6 system, 6 being a very shallow turn while 1 being almost 90 degrees. They will also have other codes for tighter turns such as: square right/left = 90 degree turn Hairpin left/right = 180 degree Open hairpin = a wider 180 degree, like an open hairpin/bobby pin Crest = slight hill Dip = slight dip in the road Jump maybe = be careful as the car may do a jump over the next section Caution, double caution, triple caution = be careful, be ready to slow down and maybe stop, stop or we die Flat = full speed Any numbers they say is usually how many meters, example “70 6-right” = shallow level 6 turn right in 70 meters It would be too difficult to remember the course layouts so the navigator uses pre defined code words or “pace notes” to tell the driver where to go. A typical set of pace notes may read something like “40 into 3right into 4 left tightens into flat 100 crest jump maybe 50 caution hairpin right” or “in 40 meters there’s a level 3 turn to the right followed by a level 4 turn to the left, you can go full speed after that but be careful as there is a slight jump in the road 100 meters up which may cause us to jump, 50 meters after that there is a 180 degree turn to the right with something you need to watch out for so be aware as you may need to avoid or slow down. There is a lot of different phrases and lingos for all different things a driver can meet on the track and each is different to each driver and co driver
