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😝🤓😎!

[@mcmtv2]

Boost is good and in this episode, Brett explains what it is and how it works - MAD!

[@DANCEGASMAN]

Would a boost controller have an effect on any turbo car, even a diesel such as a VAG 1.9 TDI 150 or....?

[@mihpop9733]

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?

[@Filip_Phreriks]

+DANCE GASMAN Yes, especially on Diesels.

[@mauriceh7558]

probably not enough effect to offset the cost

[@sebastiend.5335]

The answer's in the video!

[@DirceuCorsetti]

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.

[@Poyntlesss]

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.

[@Tool0GT92]

Just weld the waste gate shut, unlimited boost baby

[@tobalpepe446]

good luck whit that

[@imaginarytoast]

Infinity boost!

[@xBigBean]

Does this actually work of does the turbo tear itself to shreds?

[@whatyareckon5985]

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.

[@aidintaylor4669]

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.

[@Kombokiller123]

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!

[@maxx-er3fj]

It is true,i had no idea about boost pressure at all,all i knew was bigger pressure,better,now i understand

[@aarenstade]

This was very informative and easy to understand! Thanks Brett! Please make more!

[@zippy6545]

Really loving these Go Fast Brett videos, he makes it so easy to understand :D

[@lmnk7]

Learned more about turbos in 5 min, than last semester in school. Keep up the good job mcm!

[@christopherbeyer6575]

That was a fantastic explanation. Love this series

[@dumamilk]

im loving this series. keep up the good work.

[@lukasvjohansson]

That was great! Loving this series!

[@MattMacabre]

These vids are such a great idea, i've always had N/A cars and was pretty clueless on turbo set-ups until now.

[@smallenginedude71]

Great explanation. I have a much better understanding of waste gates and boost controllers now. I could listen to brett talk for hours.

[@paulrhodes6853]

These videos are great, love the info!

[@maxszeles4809]

I love the GO FAST BRETT. It's so useful!

[@bennyboy3146]

Love this vid series, already know most of the content but still love seeing it presented like this. Keep it up.

[@JQualk54]

Very well done video! Super quick and clear explanation of good ol turbskis

One of the best explanation videos iv seen about this subject...

[@Mike_44]

Such a simple but great video. Thank you!

[@InjecteDVenoM]

This series is excellent.

[@john-henrycorbett2647]

that a IS38 on the left. Shoutout the the guys on the MQB platform. Awesome vid Brett, looking forward to what is to come!

[@Doogleraia]

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.

[@jeepcollector91]

Nicely done. Thanks for the video.

[@lewisbiggs5977]

Excellent explanation, job well done guys

[@nadman009]

These videos are fantastic

[@77lewisclarke]

Great video!!! Answred a lot of questions and theory's Iv had

[@cocha6167]

I literally knew nothing about turbos after buying an XR6t last week. Thanks for the killer vid man! Totally get it now cheers 🍻

[@jd32k]

Mate that car will be sick once you get it going

[@xMods-ld8nx]

i learned all of that watching your old videos

[@ivanmazur9233]

Excellent job explaining complicated components

[@cjwrench07]

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.

[@melody3741]

i love the retro intros for mcm and this show. it reminds me of car shows when i was a kid

[@rclife2969]

Good job bro your videos really helps me thanks

[@rrwertz]

This was an awesome video. Thanks.

[@cwatson42785]

Great video guys!!

[@fistofgold1989]

this channel is awesome!

[@franciskelly2000]

How can you possibly dislike this video best one they made in a while 👍😊

[@01merkin]

Very well explained, thanks.

[@miksub1337]

Please keep doing these. Alot of these.

[@faazk]

That shocking made me sub!! Brilliant

[@vicky-nc3to]

Very well explained video.... Keep it up

[@fmn716]

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

[@DjSidewayz07]

I love this series already, MAAAAAAAAADD info

[@THOMASTTWYFORD]

Great vid, very informative thanks heaps

[@jaminford1839]

Sooo good! Clear as explication! Shot

[@fishbonemonkey]

Really good thanks Brett!

[@ggdragu6013]

Great video ! Please do a video regarding the advantages & disadvantages of air-to-air and air-to-water intercoolers

[@lmaoroflcopter]

GFB = +500KnowledgeWatts being a mechanically inept owner of a GTD. I'm loving this series that explains the basics of turbo's.

[@kogulification]

Best 5 mins of my life

[@customspraymods]

Thats awesome. Stuff you should know if you own a turbo.

[@maxx-er3fj]

Stuff you should know uf you even have a car not turbo

[@dashmason322]

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!

[@benicioenzo7663]

@Dash Mason Instablaster :)

[@broo_shs]

really well explained Really Nice

[@garypitt7020]

Well u can't get it any clearer than that thanks for your time and services to us all.

[@genepatrick]

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.

[@nivendarsoo4575]

very good explanations on boost control rate 100%

[@frederickconner8572]

Thank You! This says it all!

[@xBigBean]

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)

[@FerpiliciousProducts]

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.

[@ciarancargan6986]

I thought N75 was the one most people just deleted? I forget just now though so that could be well wrong...

[@lyndonfongtenjing5889]

very good explanation

[@iLykHardsytle]

Damn Martin!, back at it again with them terribly funny/bad car puns LOL.

[@Onhaey]

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.

[@myjizzureye]

This video was great.

[@datsuntoyy]

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.

[@SforSytosis]

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.

[@ClaytonBridges]

good video, very helpful, I did not realize thats how manual boost controllers work, very interesting! I wonder what goes on inside there

[@KatieNovaRose]

very informative. i love it.

[@nicholascroft520]

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?

[@Metal-Possum]

"I like big boost and I cannot lie" ...? Surprised nobody beat me to this one.

[@qwert_au]

and you other brothers can't deny

[@b_gumm]

Perfect. was wondering if I could lower boost. Now I know. Thanks.

[@StewartMotoring]

Awesome thanks for this

[@adzyk6197]

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..

[@010aray]

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.

[@ziploc53]

Keep up the extra content

[@amontodd551]

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!

[@cezararcega2740]

if you change the turbo for upgrade, do you need to reprogram the ECU?

[@jonnypolea3768]

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.

[@christophersaa]

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?

[@barrabois8896]

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

[@patrickbrooks8749]

Would a boost controller help boost creep stop or would i need an external wastegate for that?

[@MikesMischief]

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?

[@strider5119]

if my wastegate is adjustable, is it better to adjust that, rather than a boost tee?

[@alexgaskin2649]

Hey love the video but can you guys do a video on how blow off valves work in line with boost controllers

[@ekdromoi]

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?

[@zandelempsolo2566]

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?

[@bigmik3566]

Does turning the actuator up, the only way here that will increase boost?

[@Pustivuk]

So if its closed then you get more power? More its opend less power?

[@chrisismail]

How would you hold the boost back to make it come on harder?

[@thensm91]

If you have boost creep or spikes can a controller turn it down so that when it spikes it hits the factory levels?

[@Luckytmj97]

Do you need to have a boost tap in order to run a boost controller???

[@bigmik3566]

Hi how does the manual boost controller increase boost without turning the actuator up? Can it only reduce the pressure?

[@CoyoteRoadRunner]

ok when i drive 22psi overboost and 19psi holding boost with a electrical boost solenoid valve. what spring strength i needed for my wastegate?

[@pokemongeneral5889]

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 ?

[@jamestompkins7816]

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?

[@patterdalezipsuzilil]

Does the MAP SENSOR control the boost pressure

[@Hidfors]

Love this stuff. It might be nerdy, but it's my kind of nerdy. Please Sirs, may i have some more?

[@GodFknDamit]

so put sipmlp it acts like a thermostat but instead of working on temprature it works on pressure?

[@arriekanarie2870]

If i put a boost controller on a 2015 ford fiesta 1.6 tdci , will the engine detect that there is more air and inject more fuel ?

[@whatyareckon5985]

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.

[@wisin1988j]

hey bret i have a ebay turbo at rhe moment i has no tag or mark on the compressor but on the exhaust side it has some letter and numbers A/R .48 i need to now how to identify it on the other side any help please?

[@WarlockSRB]

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...

[@eduardozmorenodejesus8226]

This is MAD

[@boujeePerformance]

if your car wont let you turn the boost up can i just disconnect the map sensor and run more boost without it?
