dude .. its more than that.. i bet the engine also MD (moderate displacement) .. else how to "low" pressure pulse for 2 of the piston ... 
and its very advance that it is able to run the engine smoothly even with 2 different design in 1 engine .. (2 high pressure.. 2 low .. ) ... 

gosh im dying over here....

4-2-1 extractor on a 3 potter... ohh this is gold!

Dr jayraptor.... i beg you, please enlighten us on how the plumbing of a 4-2-1 extractor would look like on a 3 potter car?  Is that one extra runner connecting to the wastegate? or is it left open to relieve the wastegate? 
Please include diagrams (or any sort of visual aids) to support your answer

i trying my best to understand ....


i think it is left OPEN most likely... so that cylinder 2 and 4 can have lower pressure... OH wait ... where is cylinder 4 ...

Damn, go patent it.....

The open ended plumbing is an atmospheric ram intake to further reduce turbo lag

plausible hmmm a real interesting design

u also join the bandwagon ? lolzzzzzz

remember.. the objective is to show jay bodohness.... 

typical 4 pot .. firing order ... 1-3-4-2 ..
the twin scroll design is to isolate the pulse.. to prevent the exhaust clash between piston pulse for a smoother flow..
but prof jay punya is high and low pressure...
if base on the diagram .. i would says the piston for 1 and 4 is same... but different from 2 and 3... this will create vibration .. and to reduce the pressure.. i bet need to use small CC for 2-3 or the other way round... genius design wei ...

so which engine ah ... FIESTA ECOBOOST 1.0 ah ? ... that one i have a bit problem finding the 4th piston .. i wonder where ford hide it ..

What the heck is this diagram you attached? Judging by the quality of drawing and colour palette, must be from some old manual/textbook. This is definitely old obsolete tech laggy wastegated turbocharger used in Preve!

The detailed facts version wastegate function explanation puts most of you quiet because it is correct and shamed few of you who actually didn't know wastegate valve complete functions.

The VGT actuator is not in the exhaust manifold side but only at the other end of the impeller. All it does is only extend or retract the blades or fins for high or low exhaust pressure operation. The VGT turbocharger cleaning mostly on exhaust manifold and impeller, cleaning is easier and less prone to carbon buildup. Your comments clearly tells that you've never seen how people clean up carbon buildup especially diesel engines. Lol, you sure think brushing only. You should check how complex the twinscroll exhaust turbocharger and its exhaust manifold first.

I'm not surprised at all that you failed to complete the half details I posted on twinscroll turbo. So are the few of your buddies here except they backed off upon seeing the details. You're probably the weakest amongst them. Kesian, let me sedekah you the other part.

As told you, there are 2 inlet where 1 for low pressure and 1 for high pressure that goes into impeller. The exhaust manifold ports for 2 cylinder chambers that start first linked as low pressure manifold that goes into lower pressure inlet. The 2 more chambers exhaust linked into high pressure inlet. These 2 inlets called as twinscroll that flow low and high exhaust gas pressure to impeller allowing it to spin the compressor fast enough to effectively draw in dense air into combustion chamber. That's twinscroll turbo could assist from as low as 1200rpm in some configuration layout.

So you still want to talk fairytale?

@constant_weight replying to you too

Whereas modshop like Kenny and Preve turbo, these are examples of failures.

HAHAHAHAHAHAHAHAHAHA

k3nnykl82 Eh bro I ask you. Have you ever seen a 3 cylinder use a 4-2-1 manifold? The extra runner must be for decoration

Dr.Jay, not only you don't know that the 1.0 ecoboost is a 3 cylinder, you also don't know that it uses a 3-1 extractor that is built into the engine head. From outside the engine you can only see a single runner bolted to the cylinder head that directs the exhaust stream to the turbine housing.

As always, you don't know anything, but try to throw statements pulled out of thin air and try to pass them off as facts, hoping that nobody knows better. Unfortunately for you, everyone knows better than you.

Is this your details? You haven't answer me bro. How 1&3 clash with 2&4?

1 never meet 2&3 as they are isolated until after the turbocharger.

1 never meet 4 as well as they are 2 strokes apart even they go to same scroll. When 1 is at exhaust stroke, 4 is at compress stroke and vice versa.

Exhaust air is like a pulse, you can feels it if you put your hands near the exhaust. You can YouTube the sound of the Lexus LC500, you can hear the pulse from the sexy low grunt.

You see we don't anti Japanese. We anti people who talk without base.

Of wai.....wasted gate again....we're silenced by the level of your kejahilan actually 

You know shit about technical details, because you can't even understand plumbing of turbocharged cars. Another added findings thanks to dares on your eco-punt engines tech talk   

You know shit about maintenance, because hardly anyone ever cleans the internals of the turbocharger. Once carbon choked up, means order replacement internal parts. The only part that can go through cleaning is the casing nia.... 
Oh i see har.....1 side for low pressure, another side for high pressure har.....are you sure??
As i said earlier, his twinscroll ter-bo has 2 impellers, one for high pressure, another for low pressure. lololol.....

Damn the exhaust header design must be damn advanced and need additional wastegates then   
Oh wai.....

At least infected journalist know what is fact to twist....you know shit but still want to twist shit.....your "facts" ended up like twiesties shape...
