That was pretty comprehensive; we are using a twin mac dome pressure setup with a dominator. As we are using map as a pressure source, boost is climbing not as quick as desired. Now i understand why we have to use a co2 pressure source.... thanks alot....
Why they don't make a simple external wastegate with an electric actuator taking its reference in the intake manifold ?
It would be simple to connect and completly tunable at will.
exactly like an idle air control.
Sounds like what would be sick for road courses would be an auto learning co2 system. Program a Max dome pressure that's safe for the engine, then have it build a 3d plot (mph/lateral g's/dome psi) using learned wheel slip of what amount of boost is too much for the tires to handle.
Now if only I had more programming knowledge than "hello world"...
Love this video, it's making the gears turn in my head
The world of ls guys owe you a BIG thanks . This is new old school of hot rodding on the cheap.So many "tuners" won't give up any info when it is just a basic learning curve we all have to go thru . Thanks for making it simple to understand .
Also, adding boost on the top is better than bleeding at the bottom, it can help keeping the gate shut longer and not creeping open before it hits set psi. And using a computer controlled MAC you can add boost at higher rpm´s when it has passed the max torque, then it wont bend the rod as easily(can be done with timing also)=more horsepower on top with no more strain on the internals
Thank you Professor Denmah, you never know what you don’t know till you know it

Cannot thank you enuff...bloody amazing vid. Stumbles blindly thru turbo build until bad man on the tube flix on light switch.
Damn, just blew my mind with the co2 controller details. It’s fuckin awesome! I did not know how versatile it makes you’re set up
Been looking for some easy to understand info in this for planning my LS build for when I get the money, and then I see the Denmah has spoken.
You should be an Automotive Performance teacher, I enjoyed the class but I have to watch this at least 2 more times. So much to take in at once for a Rookie.
+Steve Davis haha I hear this all the time
Fuckin love the thumbnail, awesome video Matt
THERE IS NO CAROL IN HR!!!!
Same
Matt, you rule!
I got my question answered in a vid in less than 24hrs. Not bad! Thanks Matt.
The best damn guide to boost control rambletron on the internet.
Thanks for the boost control ideas! Learn something new everyday. I have heard about dome control before but didn't know how it worked. This will come in handy for a arduino project after the trans controller is figured out.
Awesome video Matt!! I get it all now. Didn't really understand wastegates till this video, now I do! Thanks!
Great video. Can't thank you enough. I have a decent grasp on the manual boost controlling methods, but was looking for more info on the CO2 electronic version, and you did a great job of clearing it up for me. Obviously there is tons more on the subject, but you did a great job of making the application easy to relate to. And the illustrations help to prevent confusion.
I know for the most part how this all works and I think u did a damn good job explaining it without blowing minds. Lol 👍
Thank you Matt! Great video! I wouldn't have a crazy turbo cadillac if it wasn't for sloppy mechanics! I appreciate all your hard work!
I have to keep coming back to this because I overthink these setups. I'm personally using a 3 port on my piggyback but building the PCB circuit to do dual MAC valve and always coming back to a dumb down, easy to understand explanation. Thanks again!
Thx bro. Video was awsome, I really like how u made sense of the dome setup with co2. Huge help. Make life so much easier trying to learn this stuff. More. More. More. 👍👍👍👊
Amazing job explaining this Matt! The technology available today for turbo cars is staggering. Thank you for sharing your knowledge.
You did a great job explaining it. I new to the world of turbos trying to figure it all out. This will help a lot. Thanks
Good job keep them come. Thanks for all the great free info. Looking forward to your megasquirt tutorial videos.
I recently got boost leash by gear (LS and tr6060 ~900whp), this helped me to understand it more thoroughly. I’ve been hesitant to play with the ramp rates. Thank you.
i run a Boost leash controller with C02 its amazing! rock solid boost control. Matt you forgot to mention with co2 you can set a boost launch psi while on 2 step or T.B. Co2 will push the gate closed so you can build boost faster while staging.
I absolutely LOVE that you did this. Saves me so much time by referencing this to my customers
Learnt a lot about co2 dome control awesome explanation!, cheers Matt
The old ball and chain. Oh spring. Seems good.
Learned something today! Thanks!
Matt, just wanna say thanks for taking the time to put this together. Keep it up!
+Kevin Armijo you’re welcome
Thank you Mr. Denmeh
Awesome video. I have been wondering about how CO2 works since they mentioned it on Street Outlaws. Thanks for explaining!
Amazing. Such a great help to the community. Thank you Matt!
Ive been using 4mm washer fluid T fittings for years. Its awsome! Lets me vary from 5-8-11-14 psi depending on how many I put in. Only issue is I loose about 2 psi for each T fitting I put in. 10psi actuator with adjustable rod is better and more stabile but its just easier and faster to ad T fittings. Btw T fittings gives a more progressive boost curve rather than a more boring, linear curve from adjustable actuator 🙂
Thank you , very informative . Did an awesome job explaining it all in a half hour video .
Lol @ thumbnail
Awesome job Matt. Dome control is basically variable pressure rate which you control pressure by timed ramp rate or some other trigger. Honestly for tuning a street car this is the way to go when dialing in your combo on a dyno.
Excellent presentation Matt.
great explanation. id like to see you push the limits of a production 5.3 block and crank, set of forged pistons and stronger rods and a pair of 80mm+ turbos
12 time i watch it becaus i learn something new each time.....
Holy information Bat Man! Now my brain hurts! Great presentation, I learned a lot...thanks for posting!
Great answers!!! I was so confused before this!! Thank you so much!
Excellent video!
I came in knowing about half this stuff. Thought I knew most. Nice video as always.
Thx for doing these videos I've learnt so much from them , well done
It's like a cooking class on making car drugs.
+shua w lmao
Great video matt. Although a few minutes in I feel your Over 50% of peoples heads by how fast and excited you talk. Not hating I understand how hard it is to explain stuff! If people truly want to learn they will understand this fully. Once again great video
i got my WRX in Allentown and drove it back to boston that night
All makes sense now !
very educational, thanks
Great video! Long time mechanic, new to Turbos..don't even have one.....yet!
you've come to the right place!
Great video Matt, had no clue how many options there are. So are you kicking off the tuning series here? I can't wait on that, it's so hard to find reliable info on ECU tuning.
Amazingly helpful video Matt, thank you!!
Somebody buy this man a drink!
Thanks Matt; would like to see applied examples on your builds.
I gotta say spectacular man. You seem to do your best work when you are just winging it, you have a natural ability to stream consciousness in a natural fashion that makes it easy to comprehend.
Either that or I am as insane as you are.
In either case, please keep it up, this old Mechanical Engineer appreciates you!
Thanks Matt just the kind of boost control information I needed.
Great vid Matt, very good explanation.
Good Job!
Great info brother
Nice job. i have a small turbo on my race bike, and was going to use a solenoid and regulator for second stage boost, since it builds boost so fast. but good explination on dome control. reading lots about settings on the ms3x, and it looks to be straight forward.
Well shit, you're eventually gonna give out all your secrets to make these LS motors chooch.
Just wondering, if the co2 just applies pressure to the top of the waste gate to control boost, why not just put an built in electronic actuator at the top of the wastegate to simplify the setup and have infinite adjustability and feedback? Is it heat, size of unit, amount of pressure to hold the valve closed, or a combination of all of these?
Thank you so much Matt !!!!
this video just helped me out a bunch , thank you
Matt,
Does it matter where you place the boost reference connection on the compressor? Close to the outlet? predetermined aluminum castinging?
Can't believe you didn't tell people to not use the fire ring as a mating flange.
DEBOSS GARAGE seriously? Do you have a reference that gives more info?
I'm sure the C02 setup would work great for laggy setups in drifting to get the power back on without having to wait for everything to catch up.
possibly, if there is a lot of the half venting going on or slightly open on the gate, also springing more, or using boost on top recirculate can also help out if it is cracking early and bleeding
I know of one driver with a big turbo 2jz ~ 800-1000whp using it with anti-lag, but I didn't know enough about it until now to know who does and doesn't run it, but it makes sense.
Absolute gold Matt. Thanks for this. I have a lot better understanding of how all this shit works now :)
Extremely helpful! Thanks again
very informative!! thank you
Would love to see this with a term x set up and how it’s set up, if it needs a output set and such. Thanks for the info none the less.
I’ve done two videos on terminator boost control heads up
This is my second time watching this video, im finally at the point in my build where Im making a decision of boost controllers and widebands. Looking into combos and want legit answers and not hit it with your purse or memes as an answer. If anyone has some good ideas im all ears.
Great job! That was really informative and straight forward. Thanks teach!
Great info Matt! I like these vids.
Thanks a lot Matt!!
Great vid moot hoopppel (denmarshe) explained extremely well, although i have 2 questions
Why use c02 instead of oxygen? (Assuming fore hazard)
Can a stock ls truck or car ecu support closed loop boost control using hp tuners? I know with the aussie turbo barra ecu it comes stock with a turbo you can tune with closed loop boost control with hp tuners
thanks matt
All the mysterious tuning wizards are like, nooooo!!!!! Our secrets!!!!
Yup. They get very critical.
It was really great. I appreciate the info
great video!!!
Thank you sir!
Dome control is how the street outlaw guys are taking power out of the cars when you hear them say that on the show.BIG TIRE MORE POWER.
From my understanding people are now using traction control to pull timing instead of changing boost pressures during a run. Reason behind this is timing is an instant change where there is always lag when changing boost
For sure, or even drop cylinders. ruclips.net/video/iP8sfonI9cM/видео.html
yes but traction control slows a car down no matter what, also they are still using a boost ramp in combination.
you cant leave with 75lbs of boost in a 4500hp car and just adjust timing to manage power
truboost is independent of the ecu correct? so you wouldn't be able to do a ramp like boost vs. time with the truboost? thanks for the vid
correct, it is a stand alone
thank you!
tuning class is in session!
Running split line to top/bottom port from turbo should give you the same boost as running no reference line. 3 top/3 bot = atmosphere top/atmosphere bot
consider, its working normally with bottom reference, then you add 3lb of pressure to the top it has to combat with, why would it negate it, its adding pressure. instead of just venting nothing in the hat, if you put boost in the intake of a car, at 50lbs of fuel pressure, and run 10lbs of boost, you're killing off 10lbs of fuel pressure, because the injector has to spray into 10lbs, thus making the injector less effective, same thing is going on here. adding pressure to the top, gives the backpressure in the exhaust something more to work against, not less. pretty simple.
Why does it cancel out at twice the PSI though? If you've now raised it to 6 PSI when it was 3 then that's 6 PSI you can put on top of the Dome correct? Should it not increase exponentially then?
I'm not really understanding why sending the same PSI to the top and bottom doubles the boost instead of having the same effect as not having reference lines at all.
Is it because of the effective area the pressures are acting on in the system, and thus the ratio is related to the proportions of the particular wastegate, or is there something else going on that I'm not thinking about?
I have been looking for an answer to this question for quite some time. I mean, the more the Boost increases the more you're able to put on top of the Dome so why does it cancel out at twice the PSI?
Great information
I have a question Moat Hoopelz: Theoretically speaking, if I run a waste gate with no boost reference line, and i suffer from crazy boost creep (waste gate is unable to bleed exhaust), will using a stiffer spring and running a little more boost suppress that problem? Since there is less exhaust to gate, shouldn't it be easier for the WG to control?
i would say it makes creep worse as it has a higher starting point
@@SloppyMechanics 6 years lol
I shouldn't have watched this. I thought I understood boost control lol. I love your videos though.
that heated jacket is dope
yep i have loved it so far, i have had it a while and it still looks new also
ETCG here, creepin' on your vids.
You've been at that guys throat since that vid came out. This has been the funniest thing to follow man, I love it. Show no mercy. lol
I feel the same way I did when I took trig for that one day.
lol
Awesome
BADD ASS EXPLANATION!
Great video! sharing with my less informed friends. I posted this on instagram too, but i guess ill post it here. Know of anyone using a Paintball HPA tank? Theyre light, and have up to 3000 PSI. regulated to 30-50 or even 150 psi, it should last forever.
GREAT CLASS... I GOT AN A
Great job, Matt. How are you set up for your boost control on the current version of your truck?
