That's a turbo efficiency chart. It's based on rpm, displacement, and boost volume. You use these to properly match a turbo setup with your engine setup to ensure the amount of exhaust pressure your engine will produce, your engine's expected air requirements, and the turbo's ability to push air line up effectively. Most people think "bigger turbo, faster car," but this isn't the case. If you're too far out of the turbo's efficiency curve, you'll starve or overload the block. Watch Donut media's video on boosting the Miata for a good breakdown of using that chart

The amount of information in the video is INSANE. Mad props to you sir. This video needs to go viral so people actually understand what’s going on to clear up the many misconceptions we have in the car community. You’ve gained a subscriber.

All this BOV talk reminds me of a system Ford came up with for their Focus WRC car in the late 90s/early 00s. World Rally Cars have intake restrictors to keep the power down. Ford created a 'tank' at the back of the car which would capture all the air that would otherwise be vented off by the BOV. When the driver was off throttle this tank would be filled up with compressed air, which would be available for the engine once the driver floored it again. Once the FIA found out about it (it took them a few rallys IIRC) they were quick to ban it because in their eyes it negated the purpose of the intake restrictor by allowing more air than what should be available for the engine, even if only for a brief period of time.

@@moiseslopez7831 Hi Moises, the problem isn’t the box, it’s the turbo. When you accelerate hard, it takes a few seconds for the turbo to spool up to a high enough speed to provide the boost required for the engine to have the power needed to accelerate. That is the reason for twin turbo engines. They have a very small turbo that speeds up very quickly to eliminate lag, but as they are small they can’t provide high boost pressure needed for high engine revs, do a second much larger turbo is I Also in the system, which provides the boost from the mid to high engine revs. I hope this explains what is happening in your Mercedes.😃

I've just watched all 8 Boost shows - so good! Wish they were around when I did my turbocharging in the 80s.

While I normally agree with the information you provide, I have to disagree here. “Off throttle” surge or turbo flutter does not cause additional strain on the turbocharger. Since the turbocharger is under its maximum thrust load during use (for example at 20psi) shutting the throttle does NOT increase this, and therefore doesn’t load the thrust components any more than they would be during normal use. This is very different to on throttle surge (when you are actually in the surge zone) which causes huge strain on the thrust components due to being at the working thrust load @ 20psi. This will often snap the turbine shaft clean in half. Having worked in the turbo industry for a few years, I’ve never seen a failure from the lack of a BOV. If you are experiencing on throttle surge, things such as anti-surge housings will allow you to push the surge line further away. I’ve also never noticed a difference between response between bov/no bov on a vehicle, but I run my car without one. Logically, without a bov, less air will need to be re-compressed and thus speeds up response. Although this is just a guess at best :)

@d4a

2 жыл бұрын

I had another commenter mention this too. I did cover on throttle flutter at the end of the video. What damages the turbo in off throttle surge isn't the thrust load itself. It's the shock loads of the pulsation as the excess pressure exists past the wheel.. It's rapid on-off loading or in-out of the surge zone that's the problem. I had another person say how they never saw damage due to no BOV. I'm pretty sure there are no bov failures out there but the attribution of their source becomes subjective because bearing damage is bearing damage and the same damage can be attributed to multiple different sources. It's true that off throttle flutter is harmless, but that's only when boost is low. This is why some early turbo cars didn't have bovs or recirc valves. But they ran like 7-8psi (0.5bar) of boost. I believe the thinking that bovs are useless may come from this era.Today you have cars that run 1.2-1.5 bar from the factory, and they all have recirc valves. In fact all factory boosted cars today have recirc valves. Looking at it simplistically, if off throttle flutter was really harmless and bovs useless than factory cars would never have them and would happily flutter along. Anti surge housings definitely help but they can't get rid of flutter on high boost applications.

@@d4a While I would agree with your assumption, that’s not how it works in the practical world. In all turbos (both JB and BB), theres actually no contact between bearings & shaft during operation, same with the thrust washer & bearing. The so called “shock loading” your talking about would only see an effect if you had a drop on oil pressure or oil contamination, allowing for contact. When exposed to on throttle surge, it doesn’t actually harm the bearings. It can, at most, overwhelm the thrust bearing and cause a failure there. But that’s only the case if the thrust collar & bearings surface area isn’t big enough to cope. The shaft will 99% of times snap before the thrust bearing is overloaded in a surge scenario I run 1.4 bar through my turbo, and have experienced no issue. I have customers who run 1.8-2 bar through their turbos with no bov either. Just because modern manufacturers use recirc valves, doesn’t mean it’s to prevent damage. They were implemented due to noise & emission reduction, not for turbo longetivity. I’m talking from personal experience working in the industry. Maybe I’ve just been extremely lucky with all my applications, but I don’t think that’s the case. Each to their own.

The theory is sound. Boost pressure is key and this is why in the video I'm saying "if boost is high enough" a few times. Very early turbo cars didn't have recirc or bov but they ran like 7-8psi (0.5psi). Today every car has a recirc from the factory, because today we see 1-1.5 bar from the factory on some cars. I don't mean to offend anyone but bov or no bov it's hard to believe you did 150k miles with the same turbo on a car that was non-factory turbocharged and likely built to be driven hard. This has nothing to do with engine building skill but it's simply the expected life span of things. Also, a damaged bearing is a damaged bearing and will often look very similar regardless of damage source, which is why source attribution in the end becomes subjective.

Excellent, clear common language explanation. Unprovable!! PERFECT 🙂

8:30 I agree in with the reasoning here but the turbo is going to be subjected to far more extreme moments when the exhaust is accelerating the turbine from a stand still, turbo flutter will likely have no measurable impact on life span. Real compressor surge, which is when the exhaust is actively driving the turbo definitely has the capacity to damage the turbo.

@alientiger21

Жыл бұрын

was looking for a comment like this. The damage was far more prevalent in older turbos that had weaker components, but now, pretty much any relatively well built turbo is so robust that the thrust bearings and compressors have stress/strain limits much higher than anything flutter can cause (but not necessarily surge while accelerating).

Shortened life span is worth it :D Although how much it actually shortens it is the interesting question, given anecdotally people have been running bovless systems for decades without issues, mainly in lower pressure setups of less than 20psi.

Very interesting, but is there any reason to vent any of the air to the atmosphere beyond liking the sound? After an initial interval of enjoyment, I tend to find many car noises annoying so I'd like to know if recirculating all the air is actually the best for performance.

@TravisFabel

2 жыл бұрын

So there's actual performance difference and theoretical performance difference. First let's go over what we're talking about. A recirculation valve is the same thing as a blow off valve except it recirculates back into the air box. This is what a lot of OEM turbo setups do. It's why you don't hear a big pfffft on stock vehicles. Also, If you're using a metered system where you can't just lose the air, it often recirculates back just past the meter so that it stays in the system. And a blow off valve is exactly like what he showed there. It just blows the excessive pressure to the atmosphere and often has a trumpet/horn shape that allows it to make that woosh noise louder. As to your performance question. Theoretically, you've compressed this air and it's hot and you are throwing it back into the air box. Now yes it's true that the air was compressed and now it's decompressing and therefore lowering and temperature but it's also picked up some heat from the whole system being heat soaked and everything and it will be a couple degrees warmer than it started. But that's it. The difference is extremely small. The only other difference is size. Most recirculation valves are fairly small compared to blow-off valves. If you are doing a large displacement engine, large turbo, etc You need to have a big valve. If you have a undersized recirculation valve you will hear the flutter, lose wheel speed, and still have to refill the pipes. If you're running a smaller engine, you can blow off the extra air, but if you blow too much of it away you have to refill your entire system and you get a slight delay. So sizing is important. Sizing is important for the whole system though so that should be expected... Now there's also the psychological part. It definitely sounds and feels faster when you hear it compared to it being silent. For that reason alone most people doing a build will have it make some noise. You can adjust how it blows off or where it blows off too so that it's not too loud. It doesn't have to be screaming... Although a lot of companies specialize in making it do that.

the way this guy explains such complicated stuff is incredible. 6 year olds could understand this. thank you!

Great video's I've just been watching a few. A point worthy of note is when you hear compressor surge with closed throttle, the turbine is no longer under load from the exhaust as the flow to the engine has been halted so the turbo is only under load from the trapped air in the charging circuit. Its very unlikely to cause damage to a normal cars turbocharger. If you had a very large turbo like a Garrett T4 is more of a problem. If however you hear surging on acceleration it's going to be a problem, I had that on mid throttle on my subaru as it could not consume the flow rate of the turbo at mid rpm. It lucky can be fixed with mapping. In this scenario the turbo is under opposing forces from turbine to compressor, that will destroy the unit. In almost 20 years of experience I can honestly say regular turbos like T3 TD04 Vf30 etc won't mind flutter, I've never seen one fail solely because of it.

Good lmao, turbo flutter is a gift sent from the gods and should not be shunned, in any practical application a BOV is not really necessary if your turbo has ball bearings (journal bearing turbos can experience some increased wear when not running a BOV depending on the application) and sure, the flutter may "slow down" the compressor wheel a bit, but the difference compared to using a BOV is negligible if you're looking for the fastest spool-up after throttle release. So in shorter terms, flutter away! Don't pay mind to those who look down on you for enjoying yourself, they don't know what they're talking about :)
