- A quick and short video of how to adjust your turbo wastegate basic pressure.
If you have a low boost other than a boost leak, you might wana try this.
This car is a 2008 saab 9-3 2.0 but the procedure is the same for any other car except variable vane turbos .
Enjoy the video.. - Auta a dopravní prostředky
Two corrections:
@3:35 i say counterclockwise, well it depend where u looking from, look at the direction im turning the rod.
@ 5:35 i say keep the RPM between 3-4K, while the correct numbers are 2-4K
counter clockwise if you are looking in turbine or in wastegate ?
Anytime you post diy video about Saab I add it to my playlist. Thank you!
Awesome video. Gotta do the smoke test to check for boost leaks like in one of your last videos. Thanks for sharing this.
Thanks for your excellent videos..very easy and clearly explained.
BRO another great video! Thanx for putting these out, please keep these Saab videos coming, there aren't enough quality how to ones like yours out there You've got a like and a comment guaranteed from this guy on every one ; )
Pedronimus Piace thank man
Great video, thanks!!!
great vid
Thanks for not putting music in this video
Thx man!!!!
I know this is kind of old but I don't understand how adjusting the actuator rod but just the actual boost level isn't that only the spring that can change that or like if you have a goose pressure regulator that bleeds off the air but the actuator rod I don't see how that actually changes the boost level can you explain that. is it just that you're compressing the spring war and so it's almost like making the spring stronger
It does not change boost, this is just adjusting basic boost, which is basically the amount of boost the turbo will build with no electronic control, if it wasnt calibrated correctly due age or replacement, the wastegate might be in slight open position which will increase turbo lag. I hope this clears it
@@TheFlyingMechanicDIY okay it's just a fix a problem not to make more boost than the stock level sorry I use my phone's voice recognition and a lot of times it jumbles up words so I'm glad you could decipher that garble
Can you explain the principle here/
Also, which is the waste gate?
How do you determine proper adjustment?
How much can i load boost on a chevrolet yrax wastegate 1 and a half to 2 x.
Will my factory stock wastegate handle it.
Im sorry, im no mods expert by any means
Great video. Makes me want to go wrench on my car. What tool did you use to pressurize the system?
I dont think it is available outside my local market in Dubai , it is made in INDIA but doesnt have any markings any more
Hi great video thank you, I’ve set the rod to retain 3.5 bar pressure at the waste gate, started doing the procedure and the boost was building but as soon as the car became hot I’ve lost almost all boost, could it be the Fiat 500 0.9 Twin air Turbocharger Vacuum Solenoid Valve that needs replacing?
Once its cold does it build boost again ?
Thanks for the prompt response, when cold it does build pressure about half way on the gauge although twinair has not dials 🤦🏽♂️
@@fabiocallari6052 then there must be faults stored in the ECU .. u will need to read the faults first
It came up with P0236-62 Air Leakage in Turbocharger - Signal Compare Fail
@@fabiocallari6052 in this case the turbo will need a comprehensive check up, for leaks, operation of the wastegate, boost pressure sensor and turbo health
i have a saab 93 b207l no codes show but under heavy acceleration it judders and pops thru the rev range if i build up boost slowly its fine untill u have the pedal so far down any advice as im stumped
Ignition coils.
that background noise be sounding like a metallica song about to drop.......
It seems this turbo is partially different with mitsubishi engine.Turbo boost controller is in the injection pump.Waste gate in Mitsubishi is to control excess rpm of turbo charger.
Hey! I also adjust my boost pressure! I tightened my wastegate by some so it is pushing around 5-6 psi. Unfortunately I fell into a hiccup! In idle as I try to rev my engine it no longer goes into the red part of the boost gauge, it’ll max out around the middle of the boost gauge and my rpms will only max around 3,000rpm. As before if I rev to max in idle I can go all the way up to 7,000 rpm and my boost gauge would be hitting the red, I tried with and without traction control, Can you help? I have no vacuum leaks and everything seems to be running smooth while in motion. I’m not too sure if i am pre boosting in idle because the waste gate is opening earlier without the added power of my motor or what. Definitely feel a noticeable difference in low-higher rpm while driving tho and the boost activates faster! I do have a cold air intake and muff delete! Soon a tune if I cannot adjust my rev limiter problem!
So the rev limit came only after u fiddle with the wastage ? Did u perform the adaptation drive as instructed by the video @5:15 , 3rd gear or higher, RPM just above 2000, full throttle acceleration for more than 3 seconds, repeat as many times as u can
The Flying MechanicDIY Yes the rev limiter happened only after I increase my boost pressure by 1-2 psi from my stock 4 psi I was running. I did do a few pulls following the instructions, but I live in Colorado where the elevation is high and it is super hot and dry I didn’t want to over wear my engine! When I did run the car I did notice the boost consistency and peak was more efficient than before! I had no vacuum leak or strutter along the ride, it ran through all the gears perfectly! I don’t have a tune though and I might be leaning toward that being the problem! Howmany times would you recommend me holding my rpm around 2000?? In the video I’m sure you said hold between 3500-4000 at full throttle?? I will definitely try both methods to see if it’ll work! I just did an oil change too so everything should be at max efficiency for the set up I have.
I corrected the instructions in the comment section of the video.
I dont want to hold 2000rpm, i want u to start from 2000rpm, at 3rd gear, hit the accelerator fully and keep holding it for more than 3 seconds, repeat on 3,4,5th gears as many as u can and report back
I did a stage 1 tune, no more red area in the turbo gauge
What is the tool you used to measure the air pressure in the wastegate? Thanks in advance
Any generic hand pump will work, dont have the specific name of mine
@@TheFlyingMechanicDIY so a hand pump with a gauge?
@@lifesquestions5840 yes
I turned 2 times on my volvo 2.0t and i saw +1 psi. Should get more?also it safe for another 2 rod turms? Thank you.
It is always safe to adjust if the car has electronic boost control .. after u reach certain limits the adjustment will not cause any increase in boost since the electronics will prevent further boost increase
@@TheFlyingMechanicDIY thanks for your reply.
I heard many volvo owner's said boost controller won't work on our cars bcz the ECU.
Also i did 2 rod turns amd a saw from 0.6 bar to 0.7 somthing about 1.5 psi..
hello! Is it reliable or flexible to increase boost in reason to have more powerful acceleration in stock car? also i have 210 hp saab 9-3
If its done by a saab experienced tuner then yes, these can produce a safe 250hp with software tune.
@@TheFlyingMechanicDIY about software yes i know.so yo mean that,ecu wll need some correcetion?
Vaja Labadze what i mean is stage 1 (software only) will get u a nice power upgrade .. if u want to do other upgrades like intake/exhaust/turbo/injectors/fuel pump ... etc then u need another software stage like stage 2,3,4,5 depend on what upgrades u install
@@TheFlyingMechanicDIY yes i know that tuning but i asked about easy way and also not chip. as i undestand to adjust wastegate i need to change parameters of ecu,yes?
Every company sells its tunning device that you connect to the car OBD port and download the software, there is no chip for this car, and no need to adjust wast gate for this.. this video is for people who have issues with the boost .
What is the hand tool you are using? I have fault code P0033 turbo wastegate control circuit. Is that the part you are testing? My Saab is 04 9-3 convertible with 241k. Thanks!
P0033 thats for bypass solenoid or bypass valve .. mostly a ruptured diaphragm in the valve, the valve is located just under the intake side of the turbo , if its diaphragm intact then test bypass solenoid located next to throttle body.
@@TheFlyingMechanicDIY Great, thanks for replying so quickly! What is the hand tool you are using with the gauge? I might need to get one. The other problem I have is P0300, I have installed new spark (NPK) plugs and PCV valve inside intake manifold including gaskets. The PCV was bad.
@@amyfiveaquatics just a regular vacuum/pressure hand held pump .. cant recall the brand, but im sure it doesn’t matter as it is only available in our market.
Will this help my acceleration? I have an 2006 9-3 2.0T 5 speed manual with 83k miles. My acceleration is horrible! Also when I idle the gauge goes up and down between 1.5 to 1 rpm. I had the throttle body cleaned a couple years ago but problem came back rather quickly. Should I clean my fuel injectors? Is it a vacuum leak?
Also I need to re-seal my power steering pump, where the tank meets the pump is leaking. Do you know o-ring size or part number?
Could be a vacuum leak, but without a scanner cant be confirmed.
The oring size ID15.5mm OD 20.8mm part number 12807476
The Flying MechanicDIY the scanner doesn’t throw a code. Maybe it just has weak acceleration. I found the o ring online. Thanks!
They might not have cleaned it well enough. Had a similar problem on one of my old Saab 9-3s. Had to remove the throttle body completely and use carbon cleaner to get all of the carbon off of the butterfly valve.
Check the solenoid turbo booster sensor for acceleration
Anybody have a amazon link to the pump gauge?
What's that little c-clip? I need to buy a couple spares before I attempt this because I'm all thumbs and will definitely drop it lol
@LTS_FOREVER _ Cant because of covid, you have to order over the phone and pick up curbside lol.
How did you put the wastegate stick back when it's shorter??
Just pull it out a bit and stick it
@@TheFlyingMechanicDIY okay I managed to do it, mine was very hard to put because it's a brand new turbo so the spring is strong
Hi is the turbo that you're working on in this video a td04-11t or td04-14t? Is it a B207R engine?
B207R
Me too
Is it possible to manually adust a electronic wastegate?
I believe No
I get limp mode only on motorway in 5th gear below 60mph and when I put foot down
U will need to read the fault codes from the car
Boost
Hi I have a huge leak on my 2010 Audi A4 I notice rough idle at cold start then goes back to normal, but when I accelerate I have like turbo lag and then also when I Rev the engine and let go of the gas the Rev needle stays revd for a while and slowly goes down,, leak causing a lean code P2187 and P2279 codes.. I just changed Purge Valve so it's not that, could it be a bad waste gate? 🤔
Purge valve for lean codes !! Does ur car have the same style PCV valve from the video ??!!
@@TheFlyingMechanicDIY I just replace the Purge valve including all hoses, No its different the pcv is for 2.0tfsi engine and I have changed the pcv valve unit 3 times all new and still lean codes..
90s Kid , u will need a smoke test to check for leaks .
@@TheFlyingMechanicDIY I have smoke comes from under the intake box idk why
Mechanic friend says it was normal and also when I turn on my car I hear a huge vacuum suction from the intake box..?
Hi, I'm searching for a hand held (gun type) brake bleeder pump kit. The ones available near me are in inHG and mmHG unit measurement. Will that suffice?
It doesnt matter
Thank you for your reply. I have another question. I understand that to test for vacuum leaks, you pump it until it reaches 5psi and hold it there for a few seconds. But for the wastegate valve opening part, how to tell if the valve is opening at a certain psi?
Okay I might have figured it out. Sorry for posting a silly question.
I have a stutter on an 2.0, that has been there since i got it, been thru axles, turbos, coils, plugs, ion module. still there, its not something that is a huge stutter, but under acceleration you can always feel it stumbling a little bit, very annoying, not enough to throw the check engine light. any ideas?
I assume OEM plug and coils (with the engraved MITSUBISHI & SAAB names on them ) .. then u have to check fuel trims, usually Vaccum/Boost leak or lower fuel pressure under load ..
@@TheFlyingMechanicDIY what tools do i need to check those. yea got the right coils :)
oops i see ur fuel pressure and vacuum vid thanks
@@TheFlyingMechanicDIY so the same car with the sluggish vibration and crappy output, also has the dreaded p0420 code. I'm thinking the CAT is half trashed. The person that had it before me burned a valve and had it replaced. I replaced both O2 sensors, no dice. Ran 3 things of KatKleen thru it, no dice. Any other ideas to test this, other than check the pressure at the first 02 sensor "bunghole" ? which I hear should be around 1lb? while idling?
Joeybabbs .BABBS cars with plugged cat have a distinct sound to them like howling in a deep well, and it could be the reason behind it being sluggish and shaky
Not a clue what the slow mo was showing 🤷🏻♂️
What if you are getting high boost
Usually that mean ur wastegate actuator or wastagate solenoid is sticking .
I might be a little late but I have a 2.0T Saab with
-intake
-muffler delete
-catless
-kinugawa BOV
-kinugawa wastegate
-stage 3 tune from brew city boost
But when I installed my wastegate the day after I was doing pulls and started getting a code p0033 thought it was a leak but there was none so then changed one of my bypass valve by the wastegate and the other one by my throttle body and it still throws it I’ve been getting it for a while now and I can’t figure it out and it sends me on limp mode every time I get it any suggestions on what it could be ?
Change to stock BOV and try .
You Really Need to fit an Electronic Boost Controller instead of altering Wastegate spring pressure.
That way can have much better boost response, less lag and more reliable power.
EBC can keep wastegate closed until target boost reached, Some EBC can limit boost in certain gears,
Also if you have 5psi spring in WG with an EBC you can typically tune to 12-18psi boost with 5psi spring.
200-250% of wastegate spring rating.
Suprised Saab 9-3 only runs such low boost for 2008 model
i mean 1998 model WRX runs literally 3 x more boost (at 14.3psi)
Thanks indian tech support.
Im not Indian though 🤣
Я ничего не понял, что изменилось (
В том то и дело, что ничего не меняется, просто очумелые ручки чешутся и снимают подобные высеры) ни в одной инструкции по ТО на все года жизни авто не указан пункт по регулировке актуатора!
