These tutorials are a great way for the average Joe to gain insight into what the various turbo components do. Thanks for educating the masses😝🤓😎!
Bret is a great teacher! I like the way MCM is making these videos, one concept at a time. All of us had to learn it somewhere in the past so it makes things great for beginners or outsiders. I've learnt more with the super gramps series than with any other car show.
Learned some things today; understanding how things work and not just what they do greatly improves decision making and diagnosis of potential issues significantly easier. Thanks Brett for giving up your time to share some knowledge with us.
Boost is good and in this episode, Brett explains what it is and how it works - MAD!
Would a boost controller have an effect on any turbo car, even a diesel such as a VAG 1.9 TDI 150 or....?
I too am interested in this, i have a kia Ceed CRDi and was wondering if a boost controller will make it MAD or just wreck the thing?
+DANCE GASMAN Yes, especially on Diesels.
probably not enough effect to offset the cost
The answer's in the video!
He explains this so well, you could not know anything about turbos and or cars and still understand what he is on about. What a guy! Thanks!
It is true,i had no idea about boost pressure at all,all i knew was bigger pressure,better,now i understand
Learned more about turbos in 5 min, than last semester in school. Keep up the good job mcm!
Just weld the waste gate shut, unlimited boost baby
good luck whit that
Infinity boost!
Does this actually work of does the turbo tear itself to shreds?
The guys trolling. Don't weld your wastegate shut that just stupid. The only time you would do it is if you want to go form an internal to external gate without charging the turbo.
It not only tears itself to shreds but also I hear it can cause
long term brain damage to the vehicles occupants due to the massive Gs experienced
forcing ones brain into the back of your head. Serious stuff.
These vids are such a great idea, i've always had N/A cars and was pretty clueless on turbo set-ups until now.
Really loving these Go Fast Brett videos, he makes it so easy to understand :D
This was very informative and easy to understand! Thanks Brett! Please make more!
Great explanation. I have a much better understanding of waste gates and boost controllers now. I could listen to brett talk for hours.
I don't normally have the chance to work on turbos, but I really enjoy these technical videos.
I do plan on throwing a small turbo on one of my old Willys one of these years.
im loving this series. keep up the good work.
Would be interesting to see one covering crankcase ventilation with turbos and such, hell.. even an episode even just covering the topic in general would be interesting.
That was a fantastic explanation. Love this series
Love this vid series, already know most of the content but still love seeing it presented like this. Keep it up.
that a IS38 on the left. Shoutout the the guys on the MQB platform.
Awesome vid Brett, looking forward to what is to come!
I literally knew nothing about turbos after buying an XR6t last week. Thanks for the killer vid man! Totally get it now cheers 🍻
Mate that car will be sick once you get it going
That was great! Loving this series!
One of the best explanation videos iv seen about this subject...
i love the retro intros for mcm and this show. it reminds me of car shows when i was a kid
Very well done video! Super quick and clear explanation of good ol turbskis
I love the GO FAST BRETT. It's so useful!
This series is excellent.
These videos are great, love the info!
Great video !
Please do a video regarding the advantages & disadvantages of air-to-air and air-to-water intercoolers
Excellent job explaining complicated components
Such a simple but great video. Thank you!
i learned all of that watching your old videos
Really cool series! You guys should do all sorts of things like this on cars with different experts, sort of like an MCM engineering explained.
The old Corvairs had a different form of boost control. They had no wastegate or blow off valve, they used a small carburetor. A small side draft Carter YH (about 1 5/16" if memory serves). Which, on my 65 turbo promptly replaced with a Weber DCOE with 28mm chokes. The small carb not only controlled boost but make it very slow to build. It was a pain to tune but damn did it make power. Now with electronic control and FI it's amazing what turbos can do.
Excellent explanation, job well done guys
The video showed up at the perfect time! I think I have a faulty N75 valve on my 00' A6 2.7T, and this helped me pictures what's going on with my waste gate so much! (though it's still a bit different)
If you have a manual boost controller laying around you can plumb it in with the n75 valve. If you have the problem with the n75 valve and the boost controller together but not with the mbc on it's own you'll know what your problem is. At least on my friends 03 Audi TT 225hp that was the case.
I thought N75 was the one most people just deleted? I forget just now though so that could be well wrong...
Nicely done. Thanks for the video.
GFB = +500KnowledgeWatts being a mechanically inept owner of a GTD. I'm loving this series that explains the basics of turbo's.
These videos are fantastic
How can you possibly dislike this video best one they made in a while 👍😊
Great video!!! Answred a lot of questions and theory's Iv had
Hi Guys, could you do a quick episode on the difference between petrol and diesel turbos and how blow off valves (waste gates) affect each one. Thanks so much, love the channels and can't wait to see you guys on the Discovery Channel, been a fan since day one.
Please keep doing these. Alot of these.
Well u can't get it any clearer than that thanks for your time and services to us all.
Thats awesome. Stuff you should know if you own a turbo.
Stuff you should know uf you even have a car not turbo
i dont mean to be so offtopic but does anybody know a method to log back into an Instagram account??
I was dumb forgot my account password. I love any tricks you can give me!
@Dash Mason Instablaster :)
Best video ever. Simple to the point , not a ton of fluff but still very entertaining. One thing I would like to see (and I see this with a lot of videos), an outro . if you could add a little Outro maybe five seconds of thank you to the viewers just to give me time to hit the like button.
Great video guys!!
Good job bro your videos really helps me thanks
I love this series already, MAAAAAAAAADD info
Very well explained, thanks.
Awesome VID!!!
Would you be able to increase more boost if upgrading the forge internal waste gate actuator as you can change the pressure springs
This was an awesome video. Thanks.
"I like big boost and I cannot lie" ...? Surprised nobody beat me to this one.
and you other brothers can't deny
this channel is awesome!
very good explanations on boost control rate 100%
That shocking made me sub!! Brilliant
Really good thanks Brett!
Very well explained video.... Keep it up
In the 90s we used to put vacuum Ts into the wastegate line on the dodge 2.2l to up the boost for less than a dollar.
Best 5 mins of my life
Great vid, very informative thanks heaps
Perfect. was wondering if I could lower boost. Now I know. Thanks.
Sooo good! Clear as explication! Shot
This might sound rather narcissistic, but it's intended as a compliment. Even when I know everything on the subject (such as this video about boost controllers) I still REALLY enjoy watching the video. Just because it's presented and edited so well!
very good explanation
good video, very helpful, I did not realize thats how manual boost controllers work, very interesting! I wonder what goes on inside there
Thank You! This says it all!
really well explained Really Nice
Damn Martin!, back at it again with them terribly funny/bad car puns LOL.
This video was great.
Hey love the video but can you guys do a video on how blow off valves work in line with boost controllers
very informative. i love it.
Keep up the extra content
I'de like to see an episode on turbo wear. Such as wear on bearings and stuff. Maybe even how different setups wear out a turbo like single and twins and which ones put more stress on a turbo. Also just general tips on keeping your snails happy for as long as possible.
This is a well explained video. It gives me an idea how to eliminate the turbo boost control solenoid as a potential cause of a problem, whereby my engine suffers the occasional "hiccup' or 'misfire'. ( 2.0 Renault M9R diesel engine ). If the turbo boost control solenoid was faulty or sticking ( mine is making an odd vibration noise ), my assumption is that incorrect actuation of the waste gate valve might occur ( open when it should be closed and vice versa ). If removing the vacuum pipe at the waste gate, I interpret from your video that the gate valve will no longer open, and I am effectively running at maximum boost ( not ideal in terms of protecting the turbo from over-running and wearing out ), but I have eliminated the solenoid as a possible cause of the hiccup. Would you agree with that prognosis, or have any suggestions?
There are no fault codes generated, and I know there could still be problems with one or more injectors. However, when I keep a constant speed at about 70 mph, the issue doesn't occur, but I soon as I accelerate or put the engine under load, the issue becomes apparent. Actually, sometimes the 'misfire' feels like a sudden loss of ignition and gives quite a sudden jolt. It's this behaviour and the noisy solenoid that made me think of investigating the boost and vacuum system. If the boost pressure sensor was detecting too high a pressure, because the valve was not opening at all, I would expect a fault code. However, if the gate was opening and closing erratically because of a badly functioning solenoid, perhaps this could result in a sudden loss of boost. I'm not sure what impact a suddenly opened/closed waste gate ( as opposed to a gradually opened or closed waste gate ) might have on engine performance. In some ways, this is why I prefer the simpler version of controlling boost, and not the electronic version.
Awesome thanks for this
Love this stuff. It might be nerdy, but it's my kind of nerdy.
Please Sirs, may i have some more?
Could have added a bit more to this. like the differences between an internal and external gate, as well as the affects of gate size and placement.
Hi there.. Brilliant video..
May i ask u a question if u dont mind.
I have an Evo 8 and when i bought it, it already had some mods done to it.. It is rapid. It pulls hard when the turbo kicks in. But the one thing i notice is if I'm in 6th gear doing let's say 80mph and i put my accelerator most of the way down i feel like im losing boost from some where and the acceleration is patchy. I can hear like boost being released from some where? It never did this when i first bought the car. Looking at some of the receipts from previous owner i see that an upgraded actuator spring was installed. Could you shine some light on what might be the issue. It doesn't happen in 1-4th gear.. For your information i have a recirc value on it and not a dump valve..
The electronic boost controller you talked about, is it similar to what other companies call a 3 port boost solenoid which is controlled by the ecu with a tune?
So what about the "double your wastegate pressure" rule when using a boost controller. If you have a 7psi Spring, with a boost controller you'll only achieve 14psi give or take. Or the differences in 3 vs 4port electronic boost controller solenoid me.
Brett loves big boost and he cannot lie...
I have a question, lets say my wastegate and actuator were not operating properly (staying stuck closed) causing an overboost situation under boost. By removing the restrictor pill ( in a 2 port boost solenoid) will make the car run to the minimum wastegate pressure? or will still be over boosting?
I’m looking at putting a detroit 60 series turbo on a 351 Windsor. How hard would it be to control the boost on something like that?
I would like to hear Brett discuss Anti Surge Compressor Housings.
Can you make a video or comment back. With the electronic turbos can you put and blow off value or a boost gauge connected up to it ? Pls reply
This is MAD
Extremely helpful. How come nobody ever talks about the manual boost controllers: Where they go, and what they do. Not that I didn't already know, but thank you so much anyway.
Hey bro what's the difference between ebc and mbc does the electronic boost controler you just plug it and it will do thr job by itself? (Without having to make any MANUAL adjustments please respond ,thanks!
@@alexortega714 Electronic Boost Control still needs input from the user. It's just a nicer way to set your wastegate. you should also be able to see what your boost is set at in real-time before you drive the car.
Can you make a video explaining Tuning Boxes...?
Hi I have a 2.0T that keeps going into limp mode, previous owner said that the reason for this is that the forks on the turbo or bent forward, what forks?
So it actually builds up the pressure by first closing/fooling the 'sensor' and then opens, what makes the turbo spool turn faster. A bit like squeezing a water hose.
can the wastegate be left alone without a reference? will it still bleed some of the exhaust gas without being locked shut in some way?
Could that solenoid or vacuum valve make problems with turbo surging at half the throttle?
I have a 2.4JTDm and sometimes it works just fine, but sometimes it surges from 3 up to 6 gear around 1800-2000rpm (turbo reference is around 2000 I think).
Thanks...
What’s the difference between Boost pressure, boost pressure raw value, and boost pressure set point .. thanks for your time
I have a 1997 Sr20det s14 silvia stock motor . It's only running around 6psi stock I want just a bit more power. Do I get a boost controller ? Do I need to remove restrictir pill ?
Would a boost controller help boost creep stop or would i need an external wastegate for that?
Hey man, i'm trying to install a MBC on my 03 saab 93, but I noticed I have to boost pressure solenoids... one is connected to my turbo & wastegate, and one to my intake manifold. Both are 3 port pierburgh boost pressure sensors.. I read that if you have one of those you just replace with the MBC... Is this possible to install if I have 2 of these Factory boost sensors? Will the 2nd one affect my MBC if I install it to the wastegate actuator?
Hi how does the manual boost controller increase boost without turning the actuator up? Can it only reduce the pressure?
if you change the turbo for upgrade, do you need to reprogram the ECU?
If you have boost creep or spikes can a controller turn it down so that when it spikes it hits the factory levels?
So, for example, if I have a 3Lb spring installed theh 3 psi is my minimum boost level. But it could be cranked up to 6Lb with the boost controller turned up to 100%?
wow this is interesting, so i can make my own wastegate "pressure-thingy" and put it on the dash and controll the boost from there!
how about external wastegate? in the next episode?
YES PLEASE!
Real Pain
And then an electric one
