2018 VW GTI SE Ep. 25: Unitronic Turbo Inlet Elbow Detailed Installation

[@jonathanartiss1801]

The pull and wiggle method saved me on the constant pressure plug. Thanks for the tip!

[@LastHumansGarage]

Glad it helped!

[@motor_citymuscle288]

Mine will not come out💀👹👹👹

[@motor_citymuscle288]

Got the fucker!!

[@ryantornai945]

Just picked up a 2016 GTI. Moving on from a MK5. Been wanting an MQB car since 2015. Looking forward to going back through a lot of your old GTI vids.

[@LastHumansGarage]

sweet brother, i prob have 2000 MK6/MK7 GTI vids, good luck!

[@DCassidy42]

8:25 The reason why is because as it narrows it causes the stream of air to accelerate into the turbo. Inversely, imagine having a leaf blower with a 6 inch tube on it, verses a 3 inch. The 3inch is going to produce a more and more pressurized consistent, higher velocity flow. Pressure equals force divided by area. This is also why the GTI/R don't need a aftermarket intake until the EA888 produces over 400hp.

[@LastHumansGarage]

cool

[@jeffjones1858]

More pressure from a smaller passage (inlet elbow) before the turbo means the pressure differential needed to get air into the turbo must be greater. The compressor needs to create a low pressure region to draw air in and that is work that the turbine needs to put into the shaft. Requiring more work to accomplish drawing the same amount of air into the turbo is decreasing the overall system efficiency.

[@unenfantdesiles]

So is that means that the stock turbo inlet pipe is better before 400hp ???? Please answer me cause I just installed the unitronic one and I feel like I've lost boost and torque.... So I'm planning on reinstall the stock one 😭

[@LastHumansGarage]

@@unenfantdesiles im not technical enough to answer that.. i know that when i went back to my stock one i immediately felt a big drop in power in midrange and had to reinstall it,.

[@DCassidy42]

@@unenfantdesiles Unless you are producing a preposterous amount of power the stoke pipe is totally fine.

[@blower1]

Liking all this lovely GTI stuff :) Nice part, great install detail.

[@LastHumansGarage]

that's about it for now.. nothing else in the pipe for a while.

[@yoadriaaannn]

Mine is sitting on my work bench......maybe next weekend I'll get it install along w/ the new rs7 plugs and coils. I have their intercooler but Cobb CAI. This video will be a huge help!!

[@LastHumansGarage]

their intercooler is awesome. you installed it or a shop?

[@alexdonaldson51]

Love your videos, being a new dsg owner it's quite educational

[@LastHumansGarage]

thanks

[@maveric585]

Your attention to detail is awesome keep up the good work!!

[@boombox469]

It looks heavy

[@funky_bottoms8675]

Great segment.👍 I bought and tried the same equipment but the ECS silicone hose did not fit the Unitronic turbo inlet. Any suggestions?

[@LastHumansGarage]

all those hoses are a bad fit. i use oem hose on mine, fits perfect

[@ACRoomReviews]

Very good video nice good footage and your calm while doing it. Going to be ordering one for my new Passat.

[@LastHumansGarage]

Thanks 👍

[@DanielC.959]

Awesome stuff!

[@zone47]

Why are there always emergency vehicle sirens going off in your neighborhood? Good video, good tips, thanks for the video, I'm doing a ECS version which is probably close to the same. That PCV hose has me worried but it looks like it's doable.

[@LastHumansGarage]

Good question!

[@funky_bottoms8675]

I had an issue with my Unitronic install. The brace on the inlet didn’t line up exactly with the hole where the tork bit bolt went.

[@LastHumansGarage]

its not dead on perfect, you are correct. but def close enough where i wasnt stripping anything. i bet you can very carefully drill out one of those pass thru holes a hair larger to solve it. can't remember the setup right now.

[@billynguyen710]

Thanks for posting this video. Did you ever run into any issues with the PCV hose connecting properly to the Turbo Inlet Pipe? For example, leaks or signs of oil on the outside of the area where the PCV hose connects to the TIP?

[@LastHumansGarage]

bro... 100% guaranteed as soon as you touch that thing. they all seep. I clean the oil mist off mine about once every 3 months. but i replaced it with the better one with push clips. i have a video somewhere.

[@tfuntoy]

Nicely done man

[@jasonmotanky73]

Wad it difficult to get the tube off? Any difference on the butt dyno?

[@LastHumansGarage]

a bit. cant really tell in real life, not many could. it all adds up to my full stage 2 picture tho.

[@yoadriaaannn]

Have you done the GFB diverter yet?

[@LastHumansGarage]

naw, i don't want the spacer this time. had it a bunch of times. wasn't really worth anything in my opinion.

[@yoadriaaannn]

I have it to be installed, on my 2015 wrx it made a lot of difference in drivability and turbo response and boost stability. We'll see about it on the mk7.

[@LastHumansGarage]

oh i need one bad. its 80-100F for months here in VA.

[@LastHumansGarage]

oh... somehow i thought that was an intercooler question....

[@yoadriaaannn]

LastHumansGarage already did the uni ic, I’m in Palm Beach, always hot in south Florida.

[@unenfantdesiles]

So much good tips ahah thanks man !

[@LastHumansGarage]

thanks

[@johnlong8693]

Hey man, did it make any difference before i purchase for my car?

[@LastHumansGarage]

not so much on stage 1. i bought it for stage 2.

[@momuhairi]

does it require programming !!

[@LastHumansGarage]

no.

[@hoselrocket2001]

You didn't have to take the T30 bolt all the way out to remove the inlet pipe. Just loosen and leave it there.

[@LastHumansGarage]

good call! if you still had the retention washer in there...

[@yoadriaaannn]

Ultimate Racing has a nice DP w/ 400 cell cat and it's resonated. Quiet performance.

[@LastHumansGarage]

yup. i had ultimate racing downpipe on my MK6 GTI's. twice. the one with resonator. i had talked with them a few weeks ago about sending a downpipe. but we lost touch. ill check again, cuz its not the worst downpipe by any means.

[@yoadriaaannn]

I run it on my mk7 PP gti, along w/ Cobb cat back. I didn't like the droning around 80-90 mph and certain rpm's while driving around town. I'll be looking to either adda bigger muffler or an extra resonator.

[@LastHumansGarage]

really.. even with the resonator on downpipe? of course i have a stock catback.. i'd prob be ok.

[@LastHumansGarage]

so it fits a PP car? how exact was the fitment, especially the red rubber pegs and upper cross bracket? all bolts perfect or close?

[@yoadriaaannn]

LastHumansGarage Stock catback will be fine, I replaced mine because I’m going is38 soon.

[@gs2blade]

Man great video bro live all the details. I have to the mod . Any HP gains ?

[@LastHumansGarage]

dunno.. probably with stage 2. not so sure on stage 1.

[@LastHumansGarage]

the video makes my fingernails look like i been clay barring all day! they are not yellow at all! weird!

[@rambow70]

Am I crazy or the fact that they have the same inlet and outlet size means they'll flow the same? I think the Unitronic part looks beefier because of all that material that makes the part ticker. If they have the same diameter holes then this upgrade doesn't make any sense.

[@LastHumansGarage]

yes, you are crazy. its not about inlet and outlet size. its about the flow between those 2 points. just like any other mod. all the small things add up.

[@ZioGiGi]

next time use silicone not oil. oil and rubber dont mix, the O-ring will start to swell.

[@LastHumansGarage]

cool

[@gamecock2465]

Looks like a quality part. I think the inside of it should be polished but the benefit of that is probably not worth the effort and time to Unitronic..

[@LastHumansGarage]

exactly. polished would have been better, but prob another $40-$60.

[@jimmcfarland3446]

Same size intake. No gain.

[@LastHumansGarage]

lol! right on!

[@99SVTBolt]

Stock TIP flows at 361 CFM. The Unitronic TIP flows at 389 CFM.

[@WaseemKhan-iu4bh]

There is definitely a gain if u using the stock airbox and stock hose with this turbo inlet pipe

[@reconbullet5449]

It looks Like yours is broken cause mine has a clip, it's a squeeze in clip to pop it out

[@LastHumansGarage]

older years had squeezers. i replaced my hose with a squeezer too

[@7spower83]

LOL. Do you think Unitronic Motorsport has the VAG's R&D budget? Duh. The reason to have a large intake diameter that tapers to a smaller diameter is to increase - speed up - the air velocity to the intake manifold runners. Vout>Vin. This is the Bernoulli principle in practice. Grab a garden hose and turn on the tap. Pinch the other end and the water will shoot up. VAG saved the R&D money for you, but in turn, you burnt that money and bought a dumb design turbo Low Flow inlet pipe. Duh!!!

[@LastHumansGarage]

the midrange power is noticeable. to each their own.

[@LastHumansGarage]

and.. VW made the perfect inlet for a stock system. i'm sure it is perfectly matched. for a stage 2 system with twice the flow of stock, the VW design is less than optimal. Duh.

[@7spower83]

@@LastHumansGarage Obviously, you don't understand Bernoulli's principle.
