Can’t thank you enough for the time and knowledge you dump into this channel. I’ve only owned my Subie for about a year, but with your videos and guidance it has helped me in my aftermarket purchases and given me the confidence to do almost all of my mods myself. Once again, thank you!

When it comes to wastegate spring sizing you typically want to put in a size that is 60 percent of your target boost pressure that way when the tuner is adjusting your boost pressure it requires a larger percentage of duty cycle giving him better control. I.e. you don't want to add 5 percent and boost pressure rise 7 psi you want to add 20 percent and get 7 psi. Remember the tuner can double whatever the spring pressure is in the Wastegate.

I found this channel exactly when I needed it! All of the information I’ve been getting from you is going to help me turn my daily driver WRX into the car of my dreams!

Literally just built my motor with forged internals and I can honestly say I couldn’t b happier to see u made this video I’m shooting for 450 wheel whenever I’m done with the build

Dude I love ur content so much I recently tracked my 2009 WRX. It only has a few mods but your how to build Subaru’s reliable video has given me a clear mod path that I really appreciate!

Been waiting for this video for while thank you so much 🙌🏼

Recently just picked up a 17 wrx and been watching a ton of your videos. Tons of great info 👌

So informative as always! I could listen to you talk about cars all day haha.

Thank you! Another helpful video as I go down this Subaru modifying road.

The like to un-like ratio is amazing! Great video!

It's like the more modifications you do, the longer your beard gets. The longer your bear grows, the more you're like a Socrates for the car community. Keep it up Tanner!

My dude... you have so much knowledge lol it's like you should be a college professor teaching us about Subaru technology. Half the time I have NO IDEA what you're talking about but I'm LOVING every bit of it!

This vid definitely helped me with my build. Once again Tanner, well done.

Awesome video, my dude! I've always wondered about the functionality of wastegates...

People always said that the internal wastegate is better for my legacy, after watching this video I have a little project on my hands. Looking forward to installing the wastegates on my twin scroll.

Like watching these info videos after watching the install videos. Comes full circle. Thanks!

Man thank u for the breakdown!!!! This is my first subie n their is so much learn!!!! Thanks!!!!!

External wastgates sound amazing in my opinion.🤘

All right guys, I have a 2013 automatic 1.4 Cruze stock besides the air filter. I don't want to tune my car because I have 174,000 mi and it is my daily. Can I get a wastegate aftermarket is it worth it or not and what kind.

As long as you’re making videos Tanner I’m subscribed ✊🏻✌️👍🤚🏻

thanks smeedia for taking my suggestion

Thanks man that helped out a lot I'm actually going with an external wastegate setup on my blobeye

Great video, lots of facts. Thank you

Great video like always...

When choosing a spring pressure, is it logical to add your desired boost to the exhaust pressure to get desired boost when you're bench checking, otherwise have the exhaust pressure blow your wastegate off the seat prematurely?

18mm diameter gives you 9*9/3,14=254,34 area external 38 diameter 19*19/3,14=1133,54 which is 400% more except that you are spot on.nice job.

Thanks for all the information my dude

Awesome vid as usual! Definitely informative! Thank you

i went for twin 50mm on my 427 LS 98mm Turbo

So I'm going to be running twin GT35s on a 5.3 LS is 44 mm wastegates too big and 50 mm flow off valves mine is going to be a blow through setup and the max boost will probably be somewhere between 15 to 20 lb.

That’s it I’m buying an external wastegate. Which would be quieter a Tial or Turbosmart EWG? 2004 wrx with an ebcs and 16gxt

This helped tremendously! For just good reliability on 2013 sti stock turbo do you think the 44mm Tial-MV-R is a good choice? Mods: TGV delete Secondary air pump delete Cobb intake Invidia catless downpipe Type one racing exhaust. I know you get a lot of repetitive questions I'm getting my car pro tuned at drive auto sports in Everett and was going back watching your videos and came across to late🤣

after having my turbo kit done for almost a month. car was dumping all exhaust out of the dump tube. no boost. loud abnoxious noise, all to find out i forgot to put the firing ring inside the wastegate. lmao glad i watched this video thru and saw you do that during the process or i would still be trying to figure out why this car doesn't run after spending 4900$ on a turbo setup! 😂😂😂

Always a pleasure to watch!!

If I don’t want any gains and want a 38mm Tial ewg just purely for sound and to eliminate my thought of boost creep can i do it without getting a 3rd pro tune? Just for sound

How about for diesel turbo waste gate bro... How many psi is for daily use..

Absolute A1 video, very educational...

So if I were to add an external wastegate, do I have to remove the 3port boost controller since it interferes with it?

1 question I have, do you have to weld the internal waste gate shut in order to use an external? That’s what It looked like in the second picture you showed? Otherwise how else can you do it? Buy a new turbo?

Doesn't the blow off valve do the same thing if you keep 25lbs springs if the turbo went past wouldn't the extra just bleed off when the spring opens up thus eliminating a need for a waste gate?.

Waste Gate knowledge, oh yeahhhhh.

Do a d series turbo build

When u search for wastegate info and smeedia is the first video to show up

Thank you Tanner...latest subscriber!

I’m Running at turbo smart wastegate 14psi spring but only making 10psi no boost leaks is normal my tuner is say this isn’t normal but the company I got the turbo kit from is saying it’s normal to make less than what the spring is rated for

Love this guy videos

So would you recommend the 38mm ewg for a blouch 1.5 xtr on a 21 sti?

Can you go internal to external?

THE GOAT HAS POSTED! Love ur vids homie! Keep this shit up :)

Hey brother. Can you do a video for Maintaining waste gate and turbo. Can re-port wastegate flap?

Very clear and easy to understand information, best wastegate video I ever seen by far (I seen dozens of them) thanks!

Dig the artic camo hoodie; is that on your merch store?

Nice man . But can you go ewg on stock turbo ?????

Loving the new thumbnails

Quick question, I’m trying to put together a compound turbo and I’m thinking of running an internal wastegate on the smaller turbo but an external wastegate on the larger one, does that sound right or dumb? Great video and full of good knowledge 👍

I’m having boost problems after a intercooler pipe popped off after fmic install on a Subaru lgt. I’m only hitting 8 psi now instead of 15 psi. Tested for boost leaks and there was nothing, could this be a waste gate problem?

Can we still do external wastegates even with green speed if you are still on Cobb’s tuning platform?? I need to know because I need that external wastegate life!

Hold up that lighting though is fire!!

I need help figuring out how to pick out an upipe because tomies ELH apparently are 3 bolt pattern while most EWG are 2 bolt? not sure what this means

Who makes a good up pipe for ewg it seems like all the companies I know discontinued there’s like Grimm speed Cobb Perrin

With that pink light, it looks like you've had an sti face-lift 😅

Looking for some help, please… I have a stock turbo with the cobb off the shelf tune. What should my waist gate duty cycle be right now? I just read 0.00 for wastegate duty and I feel like I have some inconsistent boost going on.

So real quick, if i want to go ewg, do i have to remove the internal waste gate by switching the hot side or can i keep both?

Thank you! Do you mind making a video on boost leaks?

Never run out of "Chooch"

What mm waste gate should I get with my fp black? My whp goal is 400 to 450. And should I get 8cm or 10cm? I do want top end power for the street.

So if I have a 44 mm turbo with a 38 psi spring will I have to order more springs or will I be fine

Great video as always 💪🏻 Is there any sound difference between the 38mm and 44mm? Either pitch or volume ?

Or have a boost control

What wastegate is recommended with a stock vf48.

Open Vs Recirc? I don't see much on why one would choose one over the other. Besides maybe with how it sounds.

When you are running an external wastegate on the stock turbo do you need to weld the internal wastegate shut or modify anything with the internal wastegate? I plan on running a catted downpipe btw.

So is it worth getting for a stock turbo set up sounds like yes but just making sure I understood exactly what you are saying

Always so helpful bro, question; currently running a catted invidia DP with a Cobb intank Etuned by STIMIKEY I was wondering would it be helpful to run a external on my 2020 sti? If so which kind you recommend? 😄 Love the vids bro!

Informative as always and for sure answered my questions for the wastegates. But I have one more for you sensei, what type of turbo inlet hose would you recommend?

What if I run a stage 2+ tune on 3 inch catless on my subaru but i dont want it to run lean?

Hello 👋🏼, I have a 13 WRX and looking forward to ordering the PLM Power Driven Subaru EWG Up Pipe with Turbosmart WG40 Gen V Wastegate kit…I’m currently on stage 2+ 93 with accessport stock turbo etc…is there any other additional parts to installing the ewg before the tune.

Hey I just came across this video, I was wondering if I NEED a new wastegate or can I just keeep the stock on the vf52 turbo on my 2011 wrx sedan, I have a ton of modifications including bigger top mount, injectors, fuel pump, catless dp, intake turbo inlet, boost controller, bypass valve etc. and i’m gonna be tuned to make 340 wheel hp soon on the stock turbo. can i keep the stock wastegate?

Hey. Thanks for the info. If I have a completely stock 21 WRX except for a Big SF intake and Cobb AP: everything else under the hood is stock. I run 93 Octane and a 93 octane/Regular waste gate OTS tune. If the car seems to sputter a little here and there: Should I try the high or low waste gate tune? Is this safe on a stock waste gate? Can I run it indefinitely? Thanks in advance.

does putting ewg and up pipe add horsepower?

4:36 , 52 percent increase in efficiency of what?

Miss the live streams great video !

Hey im buying a subaru soon that has a "boost creep" issue and it has an external wastegate. What do I do then

Could you use the killer b headers with the 2 wastegates on a WRX with a stock turbo?

6:00 just for clarity, RPMs per minute is redundant because RPM stands for revolutions per minute Basically you were saying revolutions per minute per minute

Are different downpipes necessary for different wastegates?

Sic hoodie bud 🤙 Ohh ohh wastegates 🤙👻

Can you explain the different sounds of a ewg? The 2015+ wrx with wastegates sounds like a two tone note but on some STI’s they have a one time note. How do I get the two tone note on a sti with a wastegate? I hear some sti with different size wastegates but some sound different. Is the the tune or the spring rates that affect the sound of it?

When is a good time to get a EWG? If my subaru is still stock, i would assume I wouldn't have to do it till i get more power flowing, right?

18mm WG = circumference of 81𝝅 38mm WG = circumference of 361𝝅 An increase of 446% MATHS ARE FUN

Getting a SF intake with AP for my 2020 sti. What waste gate should I run ? High or low ?

Thanks for the content! I do have one question... Is it possible/is it a good idea to run an EWG without swapping out the intake manifold? I was thinking of running IAG UELH, Up pipe, and EWG on a 93 tune with DP, TMIC, Intake, and fueling upgrades. Open to opinions...

I’ve been watching a lot of your videos on how to make the sti 300-500 hp and in one video you said if you put a catless down pipe I would need a EWG to minimize boost creep? Would I be able to use that on a 2018 sti stock turbo?

How much boost can a stock wrx handle with an intake, should I be running low wastegate? I hit 18-20 on normal wategate

Tanner, do I NEED a ewg. Living in the pnw makes me wonder cause of the weather. I currently have a stage 2 2020 sti. I want to add fuel pump injectors stumble kit and a intake should I add ewg to the list ?

So do I not need a 3 port boost controller with a ewg. Just trying to get the most out of stock turbo/motor on e85 for now until I build it down the road. (13 sti)

I already have a Tial 44mm external wastegate and my tuner told me that my wastegate is too big. Can I ask him just to adjust it with springs? Rather than buying another turbo with internal wastegate?

So what if I have the stock turbo what size wastegate should I got with?

BPV / wastegate same thing or ?

So I can put this on my wrx only had catless dp to the cat back and an intake and I tune it I’de be straight👀?
