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.
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
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!
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!
Great videos for sure. I had an 03 bug eye back in high school almost 20 years ago and just bought an 05 blob eye two weeks ago. I missed it so much haha. Congrats on the car.
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!
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.
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.
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!
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! 😂😂😂
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.
@@Smeedia thats the formula and this the reason why you need to calculate many factors when you change from internal to external since the gap is huge and the responce time of the external does not allow you to maintain the desired boost level stable cause external have more inertia since it is heavier. nice video again keep on the nice job.
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
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🤣
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
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?
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?.
A wastegate will lower turbo shaft speed, and controlling boost with a BOV leak will raise shaft speed at the same boost level. Not saying there aren't instances to do it, but not ideal for regular old boost control
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?
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 👍
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.
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!
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?
I wouldent imagine an intercooler pipe popping off causing that but could be IWG issue, Boost controller or a large vaccumm leak. Are you protuned or OTS?
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. 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.
@@Smeedia thanks a lot , I have a shop building my car currently and they got me a 44mm and I was worried it wasn’t going to be as deafening as the 38 is lol . Makes me feel better
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?
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?
@@Smeedia dope. And for the boost controller all I need to do is drill it in correct? There has been no easy explanation for placement on the boost controller
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!
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.
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?
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 ?
Awesome video. Spreading the knowledge to noobs like me lol. I do have a question though. Somewhere down the line I want a bigger turbo. Thinking of doing ELH and an up pipe. Can you do an external waste gate with a stock turbo? Not sure if it matters but I have an 08 WRX
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)
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?
Wastegates size, Boost controller, the tune. For the 2915+ they use two wastegates where the STI only uses one. The dump tube also can play a factor 🙏😁
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...
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
Hey bro I have a 2011 Subaru sti my engine blew up but I don’t know if I should go oem pistons or forged, I’m gonna go for a daily tune and probably won’t push it as much and i have a down pipe with a tomei exhaust what setup do you recommend? I just don’t want to blow up my engine again 😭
Well inform video. Literally was shopping around for a new uppipe and EWG this pass weeks. So no need to get 3 ports boost controller if I’m going EWG?
You still need one, the boost controller is what sends the signal to the wastegate to tell it to open or close. But you technically don't need one but then you can only run spring pressure off of the wastegate
