FORD'S HIDDEN BOOST Tank - Welded TITANIUM filled with ANTI-LAG

  • Ok so today we're talking about a cheat....well no....technically this wasn't a cheat it was a very very creative interpretation of the rules of the world rally championship.
    So the year is 2003 the car is the Ford Focus RS WRC 03 and the motor-sport discipline is the World Rally Championship.
    Now in 2002 Ford introduced newly designed version of the Focus for the WRC. Most of the important stuff was redesigned from the ground up, the body shell was made lighter and aerodynamic enhancements were introduced.
    But one of the most noticeably changes was the replacement of the front and rear bumpers with US spec bumpers which was a bit weird as the car was based on the European Focus. But fitting different bumpers isn't against the rules and most initially suspected that the US bumpers offered some sort of aerodynamic advantage or something.
    Now the real reason for the US bumpers is that US safety regulations demand larger and more prominent bumpers. A regulation that's notorious for uglifying many cars. But this time a larger bumper had a completely different agenda because inside the bumper the Ford World Rally team concealed a 45 liter tank made from 2mm thick titanium sheets.
    So what was the titanium tank used for? It was used to store boost. I know it may sound ridiculous but this was it's actual purpose. The tank was connected to the engine via 4 meters of 30mm diameter piping. When the car was off throttle and the turbo was generating boost that the engine wasn't ingesting this excess boost was fed into the tank. When the car got back on throttle a special valve would open and release all of the stored boost back into the engine for increased power.
    So here we have an engine and here we have a turbocharger. Combustion happens inside the cylinder and creates hot exhaust gasses. These hot gasses then exit through the exhaust manifold and drive the turbine wheel. The turbine wheel inside the exhaust side of the turbocharger is connected to the compressor wheel via a common shaft. The compressor wheel inside the intake side of the turbo sucks in air, compresses it and then sends it through the intercooler into the engine.
    So logic tells us that the faster the turbo spins the more air it can suck in. The more air it sucks in the more air it can compress generating higher boost pressure and more power. The higher the boost pressure or the pressure of the intake air the more we are stuffing into the same volume. The more air we stuff the more fuel we can add and the more powerful the combustion becomes. The more powerful the combustion the more power the engine makes and the faster the car can go.
    Now when you open the throttle fully you're letting in more air into the engine so the ECU adds more fuel to compensate and we create more powerful combustions inside the engine. This also create more exhaust gasses and more heat which is then used to drive the turbocharger faster. So the turbo starts spinning faster and faster sucking in and compressing more and more air. As it does so it starts increasing the air pressure inside the intake manifold until we reach the peak pressure our turbocharger can generate. Let's imagine that in our case that's 2 bar, which is approximately 30psi. So the turbo is stuffing air at the peak pressure it can generate which leads to the engine generating it's peak power as well. Now let's imagine we're approaching a sharp corner and we suddenly release throttle.
    At this moment we have pressurized air that has nowhere to go because entry into the engine has suddenly been blocked by the throttle plate. This is excess boost. Pressurized air inside the intake manifold that can not go into the engine.
    So here's Ford's valve, here's the tank and here's the engine. When the driver releases the throttle and anti lag kick in the valve opens. Increased boost pressure fills up the intake manifold and any excess beyond that goes into the tank. When you get back on throttle and if pressure inside the intake manifold is higher than inside the tank the throttle remains closed to prevent boost pressure being wasted on filling the tank and reducing power output. Driver let's go off the throttle again, anti lag kicks in excess boost pressure goes into the tank until eventually the pressure in the intake manifold becomes the same as in the tank. The valve now closes because tank pressure can not be increased further.
    The next time you get back on full throttle the pressure inside the tank is higher than inside the intake manifold. The valve now opens and extra air pressure rushes into the intake manifold generating higher pressure in the intake manifold than would normally be possible thus increasing the power output.

      Wouldn't the tank also serve as a "reservoir" of boost/air? It seems it would buffer against lower-RPM boost drop and provide more of a steady boost pressure beyond a typical turbo efficiency/pressure/flow envelope and thus a bigger advantage than just a bit more peak pressure to me. Maybe with anti-lag it isn't a big effect.

      The metal always has to be cleaned very well first (assuming it is a repair job) because magnisium is typically used in gear boxes and engine blocks for aviation. Oil gets impregnated into the porous metal and needs to be removed prior to welding.
      Magnesium is pretty forgiving while welding even in comparison to aluminum. You can dip your electrode without ruining it or having to regrind.
      I use a zirconium alloyed tungsten and grind it to a blunt point. (When welding you want to nearly burry this tip into the metal)
      I preheat the parts needing to be welded to around 350°F (to avoid cracking later) magnesium that has higher percentage of zinc content is more prone to cracking.
      I keep a tank of 50-50 argon-helium mix set aside specifically for magnesium. It can be welded with pure argon but the mix is better.
      Welding magnesium is sort of sooty because of the zinc content and I clean the weld between each pass. But aside from the difference in shielding gas, the filler and prep work the process is similar to aluminum.

    At that time everyone in the WRC was using paddle shifters behind the steering wheel, with a redundant lever somewhere else in case the paddle system failed. On that 2003 Focus, Ford tried to save weight by having the handbrake double as the backup shift lever. The problem was that when you had to do that, you lost the use of the handbrake, so the driver had to slow to a crawl or even do a three point turn in tight corners. This happed on at least one or two rallies that year and cost them a ton of time.

    Minor note, at 15:30 the combustion isn't detonation unless the combustion speed is supersonic (for the fuel/air mixture, likely different to supersonic speed in normal atmosphere), for engines it's usually deflagration (flame front travels at/below the speed of sound in the fuel/air mix). This is pretty much pure pedantry, but I appreciate the detail you go into, so though I'd offer a bit more.

      Detonation would only happen if surfaces were extremely hot and high pressures were present which an exhaust pipe clearly has, large super hot surface area, combustion happening rapidly increasing the pressure which can snowball into supersonic speeds especially in the small space in the pipe.

      @k1ll3rvc 2 роки тому +7

      @@amitrkolte agree that the rapid pressure rise can cause detonation, but I don't think anti-lag causes this. normal combustion happens near TDC, which is in the 10's of cc's, late ignition and open exhaust port is a much larger volume. High temperatures, definitely, pressure not so much.
      Also the turbo needs high airflow, so you want combustion like a jet engine to minimise lag, detonation would just send a shockwave into the turbine until/unless the gas expands back down to reasonable pressure. Most of the damage to the turbo from anti-lag comes from the sustained high heat loading as the mix is still burning in the turbine rather than in the combustion chamber, where it has time to cool down as it expands during the power stroke.

    1) You can actually increase the maximum boost pressure and power with such a system. You just have to inject the tank-air behind the restrictor, right before the compressor wheel. This means the turbo can breathe in pressurised air, and compress it further. Such a setup can also help it spool up quicker.
    2) With anti-lag, the mixture isn't ignited when the exhaust valve is open, but when the piston is moving downwards. Combusion-speed is higher at higher engine pressures. And around TDC you have both a high pressure and a small volume, hence the A/F-mixture can burn up quickly; after TDC you have both an increasing volume and a lower pressure; hence it will burn slowly and keep burning during the exhaust stroke.

I would not be surprised to see compressor surge then or some weird boost oscillations. and I'm sure the engineers would have used the trick don't you think?

The pipe design was so bad that the main compressed air tank couldn't supply my tools with enough CFM and I incorporated a tank that would just fill from the main supply and the tank supplies the necessary CFM in bursts. The bay I worked in was the furthest from the main tank and a section which used 1/8" diameter hose (whatever idiot decided to use that when it was designed) I'm sure was choking the air supply.

      Right? Engine masters goes into pretty good detail on how boost levels are not a good measurement in the first place either. Boost is a measurement of restriction after the turbo. If you were to have a better valve flow on an engine you would have lower boost but higher power with the same turbo. Not really an argument I guess but kind of a interesting aside.

    • @feluke8396
      @feluke8396 2 роки тому +1

      It's way more complicated. We could say that instead of pressure, air mass would be better indicator of power. But that's not true either because you have pumping losses in engine.
      In the end, power figures are resultant of many things, beginning at engine internals and ending at air filter/exhaust muffler.
      I must agree on that bigger turbo will give you bigger power numbers at the same boost levels.

  • @GunniGST
    @GunniGST 2 роки тому +2

    What the video fails to mention is the normal maximum boost obtainable over the rev range is a curve due to the restrictor as the restrictor is a fixed volume flow per unit time device.
    Meaning you couldn´t get 2bar of boost at 4000rpm as well as 7500rpm. The pressure will have been higher since a compressor may be able to produce 2bar of boost against a engine inhaling so and so much, the compressor map definitely can reach much much higher pressure ratios, how high is just a matter of antilag calibration strategy.
    Now what this device´s main purpose I believe was is to give the engine a chance at getting that sweet sweet 2bar boost(or whatever the values really where) for a few moments at rpms which you´d normally not have it. So if you had 340hp normally at 1.4bar at 6500rpm you´d gain quite a bit of power for a moment or some moments by having 2bar boost at 6500rpm until the engine ate it up and the pressure balanced.
    The time available of this extra boosting could be easily calculated. The boost excess via the flow valves could also propably be controller so that it would "leak" higher boost into the engine above the rpm thresholds of the restrictor normally.

    12:25 well I've heard that in a B group, which had no blow off valves, the boost after you release a gas pedal, jumped up as high as 8bar and thus destroyed turbo rotor fins... The problem is with the inertia of the rotor. It can not stop instantly from lets say 100 000 rpm, so the pressure jumps higher than 30psi in your example. I've had a turbo honda civic with a homemade blow off valve, that has released only the over boost, and I could adjust it mechanically, so even though I ran on low boost like 0,7bar, once I tightened the blow off valve, the pressure gauge jumped up higher than 0,7bar, I did not try to close it completely, but the highest I have seen was 1,5bar. I bet there are videos with serious old rally cars with pressure gauges jumping much higher than a nominal boost, but maybe there were not many idiots like me, who had their boost gauges connected before the intake manifold. But if they had a one way valve in a 30mm pipe, to the tank direction and an ecu controlled valve from the tank, they could definitely have higher than 2bar.

    When you snap the throttle shut, it does create a pressure spike from all the air "stacking up" so, in theory if that tank was already 100% full, you could exceed the standard boost- so go from maybe 30psi to, say, 30.1psi! Massive boost! Great success!

  • @dabyd64

    I wonder if a system like this could be applied to road cars for a sort of 'not harmful for your engine anti-lag system'. Where the system instead of dumping the pressure into the intake for a power gain it dumps it back into the turbo to spool it back up almost instantly while the exhaust gases take their time to build up the pressure again. And considering that road cars run way less boost than rally cars the tank maybe doesn't need to be so big of made of titanium and can even come with an excess pressure valve so the tank doesn't exceed capacity and explode

    Reminds me of an experiment I read about in a drag racing forum many years ago. There once was a drag racer who wanted more power from his engine, but, having settled on the idea of adding some sort of forced induction, instead of installing NOS, a turbocharger, or a supercharger, he invented a fourth option. He ended up towing a small, custom built trailer behind his car as he went down the track, and in that trailer was a 200 gallon tank of pressurized air that was hooked up to his intake manifold via a very long length of very wide high pressure tubing. All he'd have to do to get ready before a run was simply hook the tank up to an air compressor and fill it with as much air as he could/dared to. IIRC he said it worked alright, but I think the threat of that air tank getting launched at the back of his head should he ever crash was enough to convince him to make boost with a more conventional setup.

    Subaru had been doing this for years just at a smaller scale. The Subaru "Rocket ALS" had a pressure tank the size of a 2l soda bottle on the front of the engine that would put out pressure to keep the turbos spooled up off throttle.
    The titanium rear bumper tank was perhaps lighter and better for weight distribution than having a compressing system for the pressure tank in the Subaru version.

    @mikem.9197 2 роки тому

    Pressure does not equal volume. This is why a larger turbo charger can make greater power numbers at an equal or lower pressure than a smaller turbo as long as the engine is producing enough exhaust gasses to drive the turbine. As a bonus the charge will generally be cooler as air heats as it is compressed to higher pressures. It's a lovely balance between lag/spool time and how much air volume you're looking to push from the compressor side.
    Pressure is what allows this system to work the way it does but the additional air volume provided by the tank is actually why the system works. The pressure differential allows the tank to charge and release simply by opening and closing a valve (not unlike an air compressor and its storage tank), but the additional volume of air released is what gets mixed with fuel and burns.
    This was really quite clever in its simplicity. Some only considered it cheating because they didn't think of it first and thus weren't using it on their own team's vehicles.

    I generally agree with everything you presented EXEPT; time. If a turbo is able to deliver 30 PSI boost in the steady state condition of the engine is running at full throttle, with the turbo spinning at say 20 krpm. if the driver gets off the throttle, the air that the turbo is compressing no longer has anywhere to go (it was going into the cylinders), the pressure in the manifold will then instantaneously (and momentarily) rise to well above the 30 psi that is maximum in open throttle condition, and it is this pressure that goes into the tank. Additionally, while some people incorrectly say the turbos use "free" energy, they in fact do not, they get there energy from the piston compressing the exhaust gas during the "exhaust" cycle of the engine, by bleeding off some of the excess pressure into the tank, there is less "work" for the turbo compressor to do, so it stays spinning faster. I don't know if at that time and in that class there were total fuel limits, but the system of burning fuel between the engine and the turbine wheel just to keep up the turbo RPM does use additional fuel which Ford's system could reduce.

      Is the power going into the exhaust turbine wheel 100% mechanical (pressure from the piston) or is there any percentage thermal, heat turning to mechanical energy?

      ​@@danielgodshall7502 : Both, engines typically have between 100 to 500 PSI left in the cylinder (higher range for "race" engines at full throttle) when the exhaust valve opens, but this is relieved within 30º, after that the piston is pushing, taking energy from the crankshaft.

      @@johndavidwolf4239 Thank you! So the mechanical driving pressure is parasitic just like a supercharger belt but the thermal portion would be "free" as it is otherwise exhausted heat. I wonder what is the ratio of the mechanical pressure to the thermal energy. To your point, the mechanical must be much more than the thermal.

      ​@@danielgodshall7502 Yes, "There Is No Such Thing As A Free Lunch", more so at small throttle openings where the pressurized air from the turbo is both fighting the throttle plate, and the cylinder pressure when the exhaust valve opens is lower so that little bit of uncaptured energy is less, whereas at full throttle, the cylinder pressure is higher and more of that uncaptured energy is recovered.

    My grandfather designed and built an engine that did something similar..
    However each cylinder had a dummy cylinder for the extra boost, so it was all in the engine.
    I think it was in the back of Popular Mechanics a long time ago. maybe in the 1950s or 60s.
    Was also rejected by GM for adding too much weight, and unpredictable performance/efficiency gains.
    I re-designed his (he died mid 1980s) on paper in the mid or late 90s. Never built in. I spoke to some people in the racing departments of some of the big manufacturers in the early 2000s, but they said I had to work for them, to consider my design, and that would mean they own the rights to it. I also didnt have detailed numbers to be able to make a fine tuned design. Mine was more similar to what's in this video.
    At least now I know something like this can give about a 5% improvement, and someone figured it out. Would have liked to get some of the financial benefits that could have come with it.
