@@markproper9791 there are BOVs out there that are "sequential" such as some HKS and Greddys and do indeed make the exact sounds he makes. Understandably, they're often confused for compressor surge.
If you’re not economically well off or don’t know how to work on your own car don’t buy a turbo you aren’t capable of taking care of one and it will cost you.
Honestly I think supercharged cars sound better than turbocharged ones. It doesn’t take too much of the original noise from the engine, it keeps the feel of it, you get that added whine of the supercharger, and of course power to match.
Jordan Nolan whining lol. Just like in children, I prefer not to hear it. Turbos are pleasantly disrespectful n I love it. Snorting, sneezing and spitting at other vehicles.. 🤣🤣

Yeah it's truth, you invent an attack on your state and then go to other states that have a lot of natural water and oil and kill them all because you want that.
I recently bought a new civic SI with that 1.5t mostly bc it was cheap and a manual and cool. I didnt realize I loved the turbo kicking in till I've driven it 3k miles. I love it when that acceleration hits and my steering wheel wants to go nuts and my car wants to generate lift. Turbos are fun man.

@@muskokamike127 superchargers actually have much more heat where it matters, the massive inefficiency is shown by intake temps being crazy without some sort of alcohol injection. Banks power actually just did a video on this not to long ago.
To be fair, it's way cheaper to extract more power from turbocharged engine than it is from NA. For most of those just remapping them can give 30-50BHP, and way more than that with things like bigger IC, downpipe and air induction system. Even hybrid turbochargers cheap compared to turbo/supercharging NA engine.
There are advantages to both. I love my 1.8 TSI that gets 40mpg on the highway and 35 around town but has the torque and power when and where I want it. If you know how a turbo works there's very little lag as long as you anticipate the need for the boost
Make up the lost hp?!? Todays turbo 4 bangers are outdoing old big blocks in power and fuel economy. My ford escape has almost the same power aa my old 2v 5.4 expedition
@@102wingnut I agree mate. My turbo 2.0l in my genesis coupe gets 32.4 mpg when I go on trips. But has 276hp when I ask for it. Small, turbocharged engines are the way to go. Best of both worlds
It would have been interesting if you had also talked about mean air density. I live at 5000 ft, so all things considered, a normally aspirated engine puts out about 15% less horse power. Whereas a turbo or super charged engine can maintain rated horsepower at elevations of about 8000 ft before they start to loose power.
This I always loved na buuuut I live in bc and losing more power the higher you go mean while the road is getting steeper and more curves lol bought turbo much more consistent in the mountains for sure
5000ft?? The highest point here is like 2000ft above sea level and I personally consider that already to be extremely high since I'm used to driving only 130ft above sea level.
Which is why a Swiss developed the first ever turbo for an aircraft and it went to 13,000ft and the pilots eyes froze shut. He landed it, blind, and rather than baulk about almost dying he immediately announced the success of the new device and how it vastly improved his aircrafts performance. The rest is history.
Jeremy Clarkson once showed the difference between NA and turbo lag on _Top Gear_ by racing a minivan against a Mitsu Evo FQ400. Both were in 6 gear at a matching speed, and both floored it. The minivan pulled away whilst Jeremy was sitting there waiting for the turbo to spool.
That's not lag, that's boost threshold. The Evo is obviously losing to a short geared minivan if it is before it even has a third of its torque in a gear that gets it to the much higher top speed
Ken Kalajdžič nope. The principles are the same with petrol. All 2019 petrol turbo cars are 11:1 compression ratio hence great low rpm throttle response.
@@kenkalajdzic I have a neighbor that has a diesel engine that is NA... TSI or whatever it's called... Don't know how well it works for him... But I do know that it's battery died a few times... It was in the winter...Didn't happen on ours...and our car is a TDI. :D
You have the best background of any video! You are like on vacation all day everyday with those kind of roads. The information you are giving is a bonus. I am simply enjoying the ride. Thanks.
As a fellow ME ( PhD in 85) who has built 5 turbo installations from scratch I will generally say your videos are pretty good. & granted pressures are higher as you said but you forgot one big fact. Gas runs by burning ( unless detonating) & diesels run by explosion. Big difference with regards to shock loading the engine components!
Could you explain? Seems like they both combust, creating pressure, pushing against a piston. Where's the important difference between burning and exploding here?
@@nthgth a gas engine uses spark, at a specific moment, to ignite the charge. If the initial compression ratio is too high, it ignites the charge due to the heat created by compression, too soon. This results in the charge detonating before the piston reaches top dead center where it's supposed to fire. Therefore you have pressure trying to push the piston down, on it's way up. This, at the least results in "spark knock". At the worst, it "hand grenades" the engine. A diesel engine relies on compression detonation, through compression, to fire ,or detonate the charge. That's why a diesel can handle boost at much higher compression ratios.
Manufacturers love turbo's because they can claim CAFE standards within the fleet. Easier to make a car that gets good mileage when not pushed hard, which is what they care about.
Robert Mills turbos are better fuel economy, better mid rpm torque where people actually drive, in 2019 are all 11:1 cr hence great throttle reponse. Turbos dominatw all classes of motor sport where they are allowed. All commercial vehicles are turbo with turbo trucks typically doing 1M kms between rebuilds.
IIRC turbos are great at economy ... But only when you're babying it because you're basically running a tiny NA engine. When you put down power, well now you go from 2 L to 3L and it eats fuel accordingly, and then some to keep cylinders cool.
@@Arakij11 Yes, u mean 2012 BMW 550d series with a 3L Diesel tri-turbo 381HP. There´s already the 2017 version of this car with a quad-turbo built by Borg-Warner. A few more generations and this car has more turbochargers than cylinders haha
Mazda has perfected the turbo with their 2.5 liter skyactive G motor. No lag whatsoever and absolute perfect throttle response. CX-50 turbo is the new benchmark for performance in the SUV market.
@@MrLordZenki I live in NJ next to NYC and there are plenty of open Highways and Interstates to cruise around. I used to live in Kansas City and I've driven across the states to Southern California as well as three trips from Midwest to North East. There are so many nice roads in Colorado, Utah, Nevada, Pennsylvania, and southern states.
I would be very interested in a video comparing turbo vs NA fuel economy at the same horsepower rating. For instance, take any Ecoboost and compare it to something with the same horsepower that is NA.
Since I was born in 1951 I have seen a number of trends in automobile engines over the years. Turbochargers and Superchargers have been around a number of years, however in past years most car engines were naturally aspirated. Turbochargers were found primarily on expensive high performance cars. Now because automobile manufacturers are trying to get higher fuel mileage and still have plenty of power we are now seeing a lot of four cylinder engines with turbochargers. As an example the car I drive is a 2011 BMW 328i. This car has a 3 liter 6 cylinder engine that is naturally aspirated. The BMW 3 series cars that came after this model now use a 2 liter 4 cylinder engine that is turbocharged.
Natural aspiration just gives you a nice connection to the car in my opinion. It’s probably the sound and the throttle response that makes you feel more in control
@@muskokamike127 ok good point. A turbo will give you 2x Torque of the same engine N/A. You CAN however build a small displacement Turbo engine that will give you the same or higher torque as a larger displacement NA engine.
@Jose Martins just as an example my last car was a 1.8L that made 100hp and 105ft-lb. My new car is a 1.8 turbo that makes 184hp and 199lb-ft. The torque band kicks in at 2500rpm and is pretty flat up to redline. I know people have upgraded the turbo and tune to get well over 200hp. Oh and my new car gets 2mpg less on average than the old one. Still get 40 mpg on the highway.
@Jose Martins no it's two separate cars the new one is a Golf TSI. I understand it runs about 11-12 psi. I'm still running it stock with no mods so far. Maybe a tune up in the future... Once the warranty runs out lol.
@@andreasf3064 It's a fairly reasonable example Sometimes you might need to rely on that power to save your life What if you're about to get rear ended? With a huge turbo you may not get off the line fast enough

Not sure 5.0 would be nicer to drive. Faster in straight but slowet in corners.
That 4 cylinder turbo that ford made is actually quite powerful but be careful when driving with 87 fuel, u put full throttle u will destroy the engine due to knock and the engine will also be derated slightly when running 87(knock sensor)..... Try running it on 89 it be the best combo against cost of fuel and performance
Wait the ecoboost Mustang only gets 24mpg?? I hope you’re talking about city driving because it’s common now days for a V8 engine to get at LEAST 20mpg AVERAGE

Biggest reason to get a turbo is because exhaust enters it, witchcraft happens, and you go faster. OH also.... SSSSSSSTTTTTTUUUUUUUUUSTUSTUSTUSTUSTUTSU
@@ArchimaXed Most Diesel engines(cummins) don't even have throttle bodies so a BOV won't do a damn thing. A BOV is to prevent the turbo air stalling the blades and making then spin backwards(not efficient) when the *throttle body* is closed. To visualize the importance of a BOV for efficiency, Imagine coming off the gas and your tires start spinning the opposite direction and then you have to accelerate to get them to stop spinning the wrong way and start spinning properly. That is kind of the effect you get with a turbo without a BOV. Again most diesels don't have a throttle body so it's useless on them.
@@wyattlarrick3246 Maybe it does have a BOV, it probably has a hose routed to the air intake hose to redirect that extra air back into the intake system. Many OEM turbo vehicles are like that.
I drive an F150 ecoboost with the twin turbo 6 cylinder engine. It has very little turbo lag. I have driven several other turbo'd vehicles and would in general agree with you, but the newer computer controlled systems are really good. The advantage is if you keep you foot out of it you can get the better mileage and when you feel frisky and jump on it, the engine responds with some awesome power and accel. BTW, as you know, you should always let your engine idle for a minute or so after driving to let the turbo(s) cool and avoid oil damage.
Friend could u explain me something? Lets say a turbo car makes full torque at 3500 rpm only and full power at 6000 rpm only. Between 3.5-6k rpm the turbo doesnt give its full work to the engine? Or from 3.5 to 6 it gives its full work?
Pretty sure it's just awkwardly phrased, but you shouldn't idle your engine after driving. Before coming to a stop, you should go into rpm ranges where the turbo isn't active or as active and let the wind cool ot before coming to a full stop in your parking space. Atleast that's what I remember every youtuber talking about this stressed in particular. It's the wind that cools the charger while driving, not the engine running while standing.
@@aaronschneider1581 It's both. It also depends on how complex/efficient your cooling system is but ultimately, you need air rushing over the parts to be cooled and this is achieved TWO ways. 1. Natural airflow from vehicle movement. 2. Forced air cooling using a fan.
My 2009 Volvo C70 with a 2.5 liter 5 cyl turbo with variable valve timing. It produces max torque at 1500 to about 4800. It pulls great off the line too. The auto makers know that MOST of the time the driver will spend of the time from idle to about mid rpm range. Engines with low to mid range torque are the best for street use. But in a drag race ( not often used) the high rpm hp and torque are best.
Great video! Most modern manufacturers though, use twin turbos or even twin charging (turbo and supercharger) to give you better response with minimal turbo lag. I still like my NA v8 :)
Turbos are great when you're cutting into another lane. You cut someone off but instead of accelerating into space, with the delay you make them hit their brakes, and just as they start getting mad you take off. Combine throttle by wire, turbos, and an automatic transmission hunting for gears, the look on other people's face is priceless.

Excellent video, gotta love the immediate throttle response of a good NA v8. Around 7:10 I think you may have a misunderstanding though. I don’t think the lower Static Compression Ratio (total volume at BDC vs total volume at TDC) manufacturers quote for turbo engines will actually hurt combustion efficiency. The reason being, the engine sees total, or Dynamic Compression Ratio (air density immediately before combustion vs atmospheric air density). Even though turbo engines tend to use lower SCRs (e.g., 9:1 instead of 11:1), the air has already been compressed by the turbo before it enters the combustion chamber. I think that would make up the difference. After all, the final pressure and chamber surface temperature right before the spark ignites is your limiting factor for a given octane fuel. In fact, using an intercooler will effectively compress the air further, enabling you to even get a higher DCR with a turbo engine than an NA engine. However, most of what I’ve just said goes out the window if a manufacturer’s tuning program cuts boost at low load to improve fuel economy.
I think thermal efficiency is mostly a function of the compression ratio (or decompression) during the power stroke. For ideal efficiency, you want the air in the cylinder to be at ambient temperature and pressure at the end of the power stroke. Any additional pressure and temperature is dumped through the exhaust and wasted (a turbo recovers some of that energy for powering forced induction, but that isn't power to the wheels). This is the idea behind the Atkinson cycle: a larger ratio is used during the expansion stroke than during the compression stroke, allowing the air in the cylinder to come closer to ambient pressures and temperatures, leading to greater efficiency. Forced induction and the resulting lower compression ratios do the opposite: the pressure and temperature at the end of the power stroke are increased, so there is more wasted energy, so lower thermal efficiency.
@@joopie99aa I have a Toyota V6 that runs in Atkinson mode at low load. It's a great compromise that gives real fuel economy benefit. I much prefer it to a small turbo engine or clumsy cylinder deactivation.

You should do a video on blow off valves and where to mount them.

Regardless if there is no difference. Or if there is a minimal difference.
Roger Hinman turbo lag isn’t that bad anymore thanks billet compressor and turbine wheels, increased exhaust gas speed and layout, the bearings used and the such, they’re not really that complicated and they’re pretty reliable, my 01’ Audi S4 has never had the turbos maintained or replaced in almost 200k miles, and that’s almost 2 decades old, they’re honestly pretty efficient, not really complicated and they don’t really break unless you beat the piss out of them and even then you can beat on them but take care of them with proper heating and cooling cycles and change your oil.
Roger Hinman wake up mate. All commercial vehicles and heavy machinery are turbo for efficiency and reliability. Turbo trucks typically go 1M kms between rebuilds. All 2019 turbo cars have 11:1 compression ratio hence great low rpm throttle response. I have a factory 4L turbo Barra, and the torque @ 2000rpm is amazing.
Love todays turbos, as far as throttle response, that's what the eco/sport/normal button is for. Turbo lag these days is very minimal, it's more like .5 secs later. And your torque curve depends on how big a turbo you are running. I had 3 turbos in the 90's, and one now, I'll take the turbo. And can also plug a chip giving me 48hp more, but I won't due to voiding my warranty. Your oil issue is a non issue, I talked to the manufacturer of my vehicle about the 3min warmup/cooldown I used to have to do in the 90's, they stated not really necessary as the oil lines are smaller pushing oil through faster. Only poor maintenance kills a turbo, and guess what, it kill any motor. Sound? I don't want anyone to hear me speeding.
Nope as a technician myself, I see turbo gas engines with oil changes done right at 3k miles and the oil comes out black. My oil on a NA engine at 3k miles still comes out amber. What do you think all that abrasive burnt carbon in the oil does to engine tolerances? Not to mention the heat. You burn the candle at both ends, it burns out faster.
I like that he emphasizes "delay". I do not know about others here, but I presume it take 1.0 seconds or less to reach a turbochargers rpm power band. It really depends on the turbocharger setup. NA motors are awesome, but if you want the crazier power numbers you need forced induction, unless you happen to be the happy owner of a 9.0L viper or high end Ferrari.
Yes, but they lack boost. As soon as you get to full boost, you’re at redline. You can have a turbo producing full boost-and higher boost-at as little as 1500 RPM and hold it until a 7000 RPM redline. And with a BOV and quick gear changes it’s already mostly spooled for the next pull. If Top Fuel allowed turbos they’d be doing 500 foot passes.
@@Bartonovich52 Have you watched drag strip cars which have turbochargers? They have to spool the turbo before launching. Otherwise they'd fall on their face. On the other hand, drag strip cars with a big twin-screw or roots-style supercharger nail the throttle and it's cranking out positive pressure instantly and quite a lot of it.
Then you want an older VW 8v or 16v engine. My '91 Jetta GLI has 330k miles on it. The head has never been removed. Other potential alternatives: Ford 300 cubic inch straight-six, Toyota 1UZ-FE (there's at least one with over a million miles), and probably at least a couple others that I am forgetting about.

I drive a 2018 wrx, and I can definitely say the throttle is basically an on/off switch. It's very difficult to drive the car "normally". The slightest pressure and you're hitting boost. Many modern cars have a more sensitive throttle than I'd like, but the wrx takes that to the extreme. My previous car had a mechanical throttle that gave you tons of room and a smoother response. I do like my car, but they could have tuned that throttle to be a bit less sensitive.
@@Got_Boost no that’s because honda originated as a motorcycle company and designs engines similar in that they rev higher than other cars and give power on top of the powerband. That’s why they sound different and have to be rev high to perform, but that’s why people think civic drivers can’t drive because the car is always screaming as designed.
I agree with all but point 5, I put one on a RB26, instant happiness 💯👏🏿 reliability is a *MASSIVE* factor for me, I want the car (especially if its one of my favorites) to last as long as possible, and if its boosted, then the longevity is reduced.
236 kw and only 350 nm of torque from a 3.2 6 cylinder isn't very impressive though, Turbo it and it'll have properly 100 kw more and double the torque, there's nothing N/A wise you can do to match that power.
It still is, a turbo is a ristriction in the exhaust meaning you'd still get higher temperatures at the exhaust valves. There is a reason mazda has to drop compression in their only turbo engine.
IN THE 1980"S TURBOS WERE STRICTLY OIL COOLED AND WERE REPLACED (TYPICALLY @50-60,000 MILES ON VOLVOS) WITH TURBOS (NEWER FACTORY DESIGN) THAT HAD A WATER JACKET AROUND THE TURBO AND WE NO LONGER HAD COKING (OIL BURNED TO CARBON) ON THE BEARINGS, DOUBLED THE LIFE AND THE BOOST.
I like my 2.7 turbo in my ford pickup, good power, good economy and proven reliability. You didn't mention the larger pumping losses in a larger engine.

He was actually impersonating the sound a turbocharger makes when closing the throttle without a blow-off valve installed (off throttle compressor surge). blow-off valves make whoosh or pshhh sounds.
@@markproper9791 there are BOVs out there that are "sequential" such as some HKS and Greddys and do indeed make the exact sounds he makes. Understandably, they're often confused for compressor surge.

Honestly I think supercharged cars sound better than turbocharged ones. It doesn’t take too much of the original noise from the engine, it keeps the feel of it, you get that added whine of the supercharger, and of course power to match.

To be fair, it's way cheaper to extract more power from turbocharged engine than it is from NA.
For most of those just remapping them can give 30-50BHP, and way more than that with things like bigger IC, downpipe and air induction system.
Even hybrid turbochargers cheap compared to turbo/supercharging NA engine.
There are advantages to both. I love my 1.8 TSI that gets 40mpg on the highway and 35 around town but has the torque and power when and where I want it. If you know how a turbo works there's very little lag as long as you anticipate the need for the boost

It would have been interesting if you had also talked about mean air density. I live at 5000 ft, so all things considered, a normally aspirated engine puts out about 15% less horse power. Whereas a turbo or super charged engine can maintain rated horsepower at elevations of about 8000 ft before they start to loose power.
This I always loved na buuuut I live in bc and losing more power the higher you go mean while the road is getting steeper and more curves lol bought turbo much more consistent in the mountains for sure
5000ft?? The highest point here is like 2000ft above sea level and I personally consider that already to be extremely high since I'm used to driving only 130ft above sea level.
Yeah but the air is much colder at 5000 feet than down in the city so, that helps make up for it.
@@dazeen9591 Where is here, exactly? Denver, CO is 5,279ft above sea level.

Jeremy Clarkson once showed the difference between NA and turbo lag on _Top Gear_ by racing a minivan against a Mitsu Evo FQ400. Both were in 6 gear at a matching speed, and both floored it. The minivan pulled away whilst Jeremy was sitting there waiting for the turbo to spool.
Yeah you take the worst car in history as an example, also Jeremy always exagurates on everything.
Just floor it and press the brake for a couple of seconds then release the brake at race start
WTF floors it in 6th gear lol, absolutely ridiculous.
That's not lag, that's boost threshold. The Evo is obviously losing to a short geared minivan if it is before it even has a third of its torque in a gear that gets it to the much higher top speed
That's why, for gasoline engines, a supercharger is better. No lag.

As a fellow ME ( PhD in 85) who has built 5 turbo installations from scratch I will generally say your videos are pretty good. & granted pressures are higher as you said but you forgot one big fact. Gas runs by burning ( unless detonating) & diesels run by explosion. Big difference with regards to shock loading the engine components!
Could you explain? Seems like they both combust, creating pressure, pushing against a piston. Where's the important difference between burning and exploding here?
and what? it's not like all turbos use gas while all naturals are diesel, or is it? no idea what your point is about
@@nthgth a gas engine uses spark, at a specific moment, to ignite the charge. If the initial compression ratio is too high, it ignites the charge due to the heat created by compression, too soon. This results in the charge detonating before the piston reaches top dead center where it's supposed to fire. Therefore you have pressure trying to push the piston down, on it's way up. This, at the least results in "spark knock". At the worst, it "hand grenades" the engine. A diesel engine relies on compression detonation, through compression, to fire ,or detonate the charge. That's why a diesel can handle boost at much higher compression ratios.
Man I love the sound of turbos with a cold air intake. That induction noise and that sound while the boost ramps is addicting lol. Great video 👍
Manufacturers love turbo's because they can claim CAFE standards within the fleet. Easier to make a car that gets good mileage when not pushed hard, which is what they care about.
Robert Mills turbos are better fuel economy, better mid rpm torque where people actually drive, in 2019 are all 11:1 cr hence great throttle reponse. Turbos dominatw all classes of motor sport where they are allowed. All commercial vehicles are turbo with turbo trucks typically doing 1M kms between rebuilds.
IIRC turbos are great at economy ... But only when you're babying it because you're basically running a tiny NA engine. When you put down power, well now you go from 2 L to 3L and it eats fuel accordingly, and then some to keep cylinders cool.

Never been fond of turbo on a daily driver, and that's all I can afford daily driver, highly educational I am a big fan thank you.

Since I was born in 1951 I have seen a number of trends in automobile engines over the years. Turbochargers and Superchargers have been around a number of years, however in past years most car engines were naturally aspirated. Turbochargers were found primarily on expensive high performance cars. Now because automobile manufacturers are trying to get higher fuel mileage and still have plenty of power we are now seeing a lot of four cylinder engines with turbochargers. As an example the car I drive is a 2011 BMW 328i. This car has a 3 liter 6 cylinder engine that is naturally aspirated. The BMW 3 series cars that came after this model now use a 2 liter 4 cylinder engine that is turbocharged.

Natural aspiration just gives you a nice connection to the car in my opinion. It’s probably the sound and the throttle response that makes you feel more in control
@2:29 yes but here it's like delayed gratification. Because when the boost comes on it's gonna hit with 2x the torque of the NA engine
@Jose Martins no that's about right depending on your turbo setup.
Not to mention traction issues.... Floor it, get rolling a bit and as the tires get moving the torque ramps up. Just like a multi-stage drag setup.
@@muskokamike127 ok good point. A turbo will give you 2x Torque of the same engine N/A.
You CAN however build a small displacement Turbo engine that will give you the same or higher torque as a larger displacement NA engine.
@Jose Martins just as an example my last car was a 1.8L that made 100hp and 105ft-lb. My new car is a 1.8 turbo that makes 184hp and 199lb-ft. The torque band kicks in at 2500rpm and is pretty flat up to redline. I know people have upgraded the turbo and tune to get well over 200hp.
Oh and my new car gets 2mpg less on average than the old one. Still get 40 mpg on the highway.
@Jose Martins no it's two separate cars the new one is a Golf TSI. I understand it runs about 11-12 psi. I'm still running it stock with no mods so far. Maybe a tune up in the future... Once the warranty runs out lol.

@@ArchimaXed Most Diesel engines(cummins) don't even have throttle bodies so a BOV won't do a damn thing. A BOV is to prevent the turbo air stalling the blades and making then spin backwards(not efficient) when the *throttle body* is closed.
To visualize the importance of a BOV for efficiency, Imagine coming off the gas and your tires start spinning the opposite direction and then you have to accelerate to get them to stop spinning the wrong way and start spinning properly. That is kind of the effect you get with a turbo without a BOV. Again most diesels don't have a throttle body so it's useless on them.
@@wyattlarrick3246 Maybe it does have a BOV, it probably has a hose routed to the air intake hose to redirect that extra air back into the intake system. Many OEM turbo vehicles are like that.

I drive an F150 ecoboost with the twin turbo 6 cylinder engine. It has very little turbo lag. I have driven several other turbo'd vehicles and would in general agree with you, but the newer computer controlled systems are really good. The advantage is if you keep you foot out of it you can get the better mileage and when you feel frisky and jump on it, the engine responds with some awesome power and accel. BTW, as you know, you should always let your engine idle for a minute or so after driving to let the turbo(s) cool and avoid oil damage.
Friend could u explain me something? Lets say a turbo car makes full torque at 3500 rpm only and full power at 6000 rpm only. Between 3.5-6k rpm the turbo doesnt give its full work to the engine? Or from 3.5 to 6 it gives its full work?
@@eliasaggeli1225 Between 3.5-6k the turbo will be at full boost.
Pretty sure it's just awkwardly phrased, but you shouldn't idle your engine after driving.
Before coming to a stop, you should go into rpm ranges where the turbo isn't active or as active and let the wind cool ot before coming to a full stop in your parking space.
Atleast that's what I remember every youtuber talking about this stressed in particular. It's the wind that cools the charger while driving, not the engine running while standing.
@@aaronschneider1581 It's both. It also depends on how complex/efficient your cooling system is but ultimately, you need air rushing over the parts to be cooled and this is achieved TWO ways.

The auto makers know that MOST of the time the driver will spend of the time from idle to about mid rpm range. Engines with low to mid range torque are the best for street use. But in a drag race ( not often used) the high rpm hp and torque are best.
Great video! Most modern manufacturers though, use twin turbos or even twin charging (turbo and supercharger) to give you better response with minimal turbo lag. I still like my NA v8 :)

Turbos are great when you're cutting into another lane. You cut someone off but instead of accelerating into space, with the delay you make them hit their brakes, and just as they start getting mad you take off.

Nice to know .. what about 5 reasons not to buy natural aspirated
Dont think so
Wait until he's given a turbo car to advertise
He will, he always does when he does this style video. Most likely the next week or two.
there is likely no reason not to buy a NA car
There aren't any.
Excellent video, gotta love the immediate throttle response of a good NA v8. Around 7:10 I think you may have a misunderstanding though. I don’t think the lower Static Compression Ratio (total volume at BDC vs total volume at TDC) manufacturers quote for turbo engines will actually hurt combustion efficiency. The reason being, the engine sees total, or Dynamic Compression Ratio (air density immediately before combustion vs atmospheric air density).
Even though turbo engines tend to use lower SCRs (e.g., 9:1 instead of 11:1), the air has already been compressed by the turbo before it enters the combustion chamber. I think that would make up the difference. After all, the final pressure and chamber surface temperature right before the spark ignites is your limiting factor for a given octane fuel. In fact, using an intercooler will effectively compress the air further, enabling you to even get a higher DCR with a turbo engine than an NA engine.
However, most of what I’ve just said goes out the window if a manufacturer’s tuning program cuts boost at low load to improve fuel economy.
I think thermal efficiency is mostly a function of the compression ratio (or decompression) during the power stroke. For ideal efficiency, you want the air in the cylinder to be at ambient temperature and pressure at the end of the power stroke. Any additional pressure and temperature is dumped through the exhaust and wasted (a turbo recovers some of that energy for powering forced induction, but that isn't power to the wheels). This is the idea behind the Atkinson cycle: a larger ratio is used during the expansion stroke than during the compression stroke, allowing the air in the cylinder to come closer to ambient pressures and temperatures, leading to greater efficiency. Forced induction and the resulting lower compression ratios do the opposite: the pressure and temperature at the end of the power stroke are increased, so there is more wasted energy, so lower thermal efficiency.
@@joopie99aa I have a Toyota V6 that runs in Atkinson mode at low load. It's a great compromise that gives real fuel economy benefit. I much prefer it to a small turbo engine or clumsy cylinder deactivation.
Can we get like a 5 minute video of you just making turbo noises? Thanks.
Jay G that turbo sound was spot on!
He could be driving any crap car with no sound and doing the whole motor / turbo thing in real time!

But when you turbo charge a v8 it’s even faster

“And finally, point numbe-OH OH OH OH REEIIILEEEEEEY”
Saying this half jokingly as a Honda fan:" Just get a vtec 4 cylinder and have the worst of both worlds"
Just keep climbing and see what happens.
My Country, MÉXICO, almost all of it is surrounded by two Sierras (Mountainous Chains, also called). For leaving México City, you have to climb Hill & Mountain roads in between 8,500 to 9,500 feet.
Then You see the Turbocharged vehicles "waving goodbyes" to Normal Aspirated ones.
You are correct, sir! Forced air induction ftw!
Even at 5000ft, I can feel my old NA engine lagging. I’ll put the pedal to metal and it’ll feel like I’m barely pushing.
@@TheSingleTrucker Thank You, sir.
@@404nobrakes Right sir. Mexico City is at 7,340 ft. elevation. We non-turbocharged drivers start climbing with a detriment of a 22% less power (following the old rule of thumb of -10% power for every 1,000 meters (3280 ft.) of elevation (7,340 / 328= 22.4% ("a la Jason style" Hahaha!)) Thank You, Sir.
You should do a video on blow off valves and where to mount them. There has been a debate on mounting the blow off valve in the hot side piping vs the cold side piping and I think a lot of people would really love to hear what an engineer has to to say about the issue. Regardless if there is no difference. Or if there is a minimal difference.
It depends where the air related sensors are in the car
Not a fan of turbos simply because of the lag, complexity, and reliability issues. I'll take a bigger engine and fuel bill any day.
With an overdrive transmission my 'ol Mustang would probably get 25MPG on the highway (with no engine mods whatsoever and with the original engine).
Roger Hinman turbo lag isn’t that bad anymore thanks billet compressor and turbine wheels, increased exhaust gas speed and layout, the bearings used and the such, they’re not really that complicated and they’re pretty reliable, my 01’ Audi S4 has never had the turbos maintained or replaced in almost 200k miles, and that’s almost 2 decades old, they’re honestly pretty efficient, not really complicated and they don’t really break unless you beat the piss out of them and even then you can beat on them but take care of them with proper heating and cooling cycles and change your oil.
Most Turbo vehicles are gas guzzlers too.
@@PanameraTurboSEHybrid When most people get a turbo car they always floor it so worse gas milage overall.
Roger Hinman wake up mate. All commercial vehicles and heavy machinery are turbo for efficiency and reliability. Turbo trucks typically go 1M kms between rebuilds. All 2019 turbo cars have 11:1 compression ratio hence great low rpm throttle response. I have a factory 4L turbo Barra, and the torque @ 2000rpm is amazing.
Love todays turbos, as far as throttle response, that's what the eco/sport/normal button is for. Turbo lag these days is very minimal, it's more like .5 secs later. And your torque curve depends on how big a turbo you are running. I had 3 turbos in the 90's, and one now, I'll take the turbo. And can also plug a chip giving me 48hp more, but I won't due to voiding my warranty. Your oil issue is a non issue, I talked to the manufacturer of my vehicle about the 3min warmup/cooldown I used to have to do in the 90's, they stated not really necessary as the oil lines are smaller pushing oil through faster. Only poor maintenance kills a turbo, and guess what, it kill any motor. Sound? I don't want anyone to hear me speeding.
That's encouraging
0.5s is still noticable lag
@@alsa4real that’s only if you floor it out of nowhere
Nope as a technician myself, I see turbo gas engines with oil changes done right at 3k miles and the oil comes out black. My oil on a NA engine at 3k miles still comes out amber. What do you think all that abrasive burnt carbon in the oil does to engine tolerances? Not to mention the heat. You burn the candle at both ends, it burns out faster.
@@alsa4real Agreed--very slow compared to my old NA Mazda that responded instantly.
I like that he emphasizes "delay". I do not know about others here, but I presume it take 1.0 seconds or less to reach a turbochargers rpm power band. It really depends on the turbocharger setup. NA motors are awesome, but if you want the crazier power numbers you need forced induction, unless you happen to be the happy owner of a 9.0L viper or high end Ferrari.
High end Ferrari? Like their is any other kind of Ferrari
Since 1994 I’ve owned turbocharged cars. You learn to adjust to lag. My current car has twin turbos and lag is practically zilch.
How to solve throttle response and torque curve issues on a turbocharged engine? Throw a supercharger at it.
Still not as responsive
Positive displacement superchargers don't lack response.
Yes, but they lack boost.
As soon as you get to full boost, you’re at redline.
You can have a turbo producing full boost-and higher boost-at as little as 1500 RPM and hold it until a 7000 RPM redline.
And with a BOV and quick gear changes it’s already mostly spooled for the next pull.
If Top Fuel allowed turbos they’d be doing 500 foot passes.
@@Bartonovich52 Have you watched drag strip cars which have turbochargers? They have to spool the turbo before launching. Otherwise they'd fall on their face. On the other hand, drag strip cars with a big twin-screw or roots-style supercharger nail the throttle and it's cranking out positive pressure instantly and quite a lot of it.
I.e. increase complexity...sounds not clever to me.
Screw turbo-chargers! I want a car with an engine that will last 300,000 miles.
Then you want an older VW 8v or 16v engine. My '91 Jetta GLI has 330k miles on it. The head has never been removed.
Other potential alternatives: Ford 300 cubic inch straight-six, Toyota 1UZ-FE (there's at least one with over a million miles), and probably at least a couple others that I am forgetting about.
2011 model 528i inline engine crossed already 4,50,000 km and still running
3.4 v6 2003 Tacoma I’ll be at 300k next oil change. I love that old truck but I do want something new…. I just can’t bring myself to blow the money when I already have a reliable vehicle that I’m not gonna sell
@@ham7357 I'd keep the Taco until it dies... which will probably be a very long time!
I drive a 2018 wrx, and I can definitely say the throttle is basically an on/off switch. It's very difficult to drive the car "normally". The slightest pressure and you're hitting boost. Many modern cars have a more sensitive throttle than I'd like, but the wrx takes that to the extreme. My previous car had a mechanical throttle that gave you tons of room and a smoother response.
I do like my car, but they could have tuned that throttle to be a bit less sensitive.
As a 21 WRX STi owner. I agree with this. It like either on or off. Unless you want to get up to 35 mph in like 15 seconds
i honestly like the sound of a honda 4 cylinder, they sound noticeably different than any other car manufactures 4 cylinders
As the owner of a 97 Civic that will be getting the "mini me" head swap along with a turbo and supporting mods, I can't agree more!
It sounds the worst lool
That’s because vtec
@@Got_Boost no that’s because honda originated as a motorcycle company and designs engines similar in that they rev higher than other cars and give power on top of the powerband. That’s why they sound different and have to be rev high to perform, but that’s why people think civic drivers can’t drive because the car is always screaming as designed.
I agree with all but point 5, I put one on a RB26, instant happiness 💯👏🏿 reliability is a *MASSIVE* factor for me, I want the car (especially if its one of my favorites) to last as long as possible, and if its boosted, then the longevity is reduced.
I drove a ZM3 and that engine was one of the nicest NA engines I’ve seen. Power everywhere, it was way more fun than a quick 2 litre turbo.
236 kw and only 350 nm of torque from a 3.2 6 cylinder isn't very impressive though, Turbo it and it'll have properly 100 kw more and double the torque, there's nothing N/A wise you can do to match that power.
No such thing as a quick 2 litre turbo...I'm thinking you don't really know what quick is..... Not being mean, Im just saying.
Intercoolers really solve the knock problem. Its not that much of an argument in my opinion.
It still is, a turbo is a ristriction in the exhaust meaning you'd still get higher temperatures at the exhaust valves.
There is a reason mazda has to drop compression in their only turbo engine.
@@1barnet1 Because there is more effective compression, with forced induction. Not because the exhaust valves are hotter.
IN THE 1980"S TURBOS WERE STRICTLY OIL COOLED AND WERE REPLACED (TYPICALLY @50-60,000 MILES ON VOLVOS) WITH TURBOS (NEWER FACTORY DESIGN) THAT HAD A WATER JACKET AROUND THE TURBO AND WE NO LONGER HAD COKING (OIL BURNED TO CARBON) ON THE BEARINGS, DOUBLED THE LIFE AND THE BOOST.
I like my 2.7 turbo in my ford pickup, good power, good economy and proven reliability. You didn't mention the larger pumping losses in a larger engine.
The Ford 1.5 L Ecoboost engine in my Fusion seems to be pretty good with instant boost, and it gets really good gas mileage when you’re easy on the throttle.
This guy talks out his butt have of what he said about turbo engines is dead wrong!
@reshi p you are wrong I work on a fleet of over 30 Ford f1 50 with the 3.5 ecoboost and 4 have well over 300k and the rest have over 200k on them all running like new.i have been in the field over 20 years change the oil often with good oil and they will last! So next time before you comment on something you clearly don't know crap about do us all a favor just go ahead and stick your foot in your mouth! And the best part they all have original engines and turbos imagine that.
If I extend your logic, then obviously you end up with *drum roll* electric car :-)

I’m glad I bought my truck when I did. It was my last chance to get one with no turbo, no auto transmission, no cylinder deactivation or stop/start nonsense, no push-button start, no complex infotainment system with gps maps and such. It has a radio and cruise control.
Missed 6 cylinder engines. Some of them sound absolutely amazing, regardless of being forced induction or not.

@@ACK88 All in how one drives them too, I sadly drove mine hard so the blame is mostly on me.

vinniecorleone62 you are doing something wrong mate. All commercial engines are turbo and turbo trucks typically go 1M kms between rebuilds.
I have a '19 F150 3.5 Ecoboost.
I love it.
In Eco Mode with the 36 gal. tank, I get 600+ miles on the highway, and in Sport Mode, it's an absolute beast.
My (2006) Subaru Forester has a "downsized turbocharger" ...which is nice to know. It also has a _recirculating_ blowoff valve and the previous owner replaced the intercooler with a larger STI one, so temperature should be handled a bit better.
Those roads and scenery are AMAZING!
