This guy has a crazy ability to explain things in a way that even a blockhead like me can understand. He is awesome! I wish I knew half of what he has probably forgotten about making power.
Absolutely love listening to Mike. He could talk about anything technical and it's a pleasure to take in. He has a gift of explaining things simply. You should definitely have him do an entire series of automotive explainers. Top stuff!
It's the guy on my Haynes Impreza manual pulling a new SG Fozzy XT apart.. and to hear the plethora more information he has in his mind gives me all the more confidence in the manual I bought. Thanks again Mike!
Those valve seats are a great idea!! Integrated water jacket and heat shield, that raised angle on the big boys. These wastegates are seriously well thought out. I bet those stems could use some WPC
These are the marketing videos I love watching, especially when it's from Mike. In-depth technical content from someone who actually knows what they're talking about and who isn't reciting marketing buzzwords from the catalogue. Keep this going!
I subbed to this channel for two reasons. One this channel has great info and clears up lots of questions. Two This man is AWESOME! He always looks like he's smiling! Maybe he IS smiling all the time. He looks like there's a joke that he knows and it's funny and he might share it with you if you'll just join in. LOL. I love folks like that. Mind you they are often frustrated that others think they aren't being serious about something or anything because they always have that great expression of a smile on.
Wow, this is so good, thank you! Im amazed that the diaphram can be cooled, that is so brilliant! and that there are other metals in between to deflect heat - really clever stuff! thanks again!
I ported the internal waste gate and moved the actuator farther out on the arm for more leverage and was able to eliminate boost creep and hold a higher boost with the stock turbo I was using
@@blakelip3 I was making about 42-45psi on a BW hx35. It was way out of it's range and very hot and spicy and I ended up breaking multiple shafts and sending compressor wheels into the housing. I would not recommend going that route for any kind of reliability. I was poor and wanted to go fast at the time.
I was a super broke college kid when I turbocharge my 71 Datsun. I traded my time for a broken tile 38 mm two bolt wastegate that was cracked and then took the guts out of it and put it a no-name housing and it's been in there for almost 15 years. Diaphragm still good still makes the same amount of power and no added lag.
As always, fantastic content from Mike and the MotoIQ team. Informative, interesting, and entertaining! Thank you for all your effort, and I look forward to the next video/article.
How do you compare these to the Turbo Smart’s hyper gate external waste gate’s design? They seem to be very similar. What do you prefer a 4 port boost solenoid or two 3 port solenoid in a pull push configuration? Waiting for Garrett to release their electric turbos at the next SEMA show.
@@motoiq I’m using Turbosmart’s 45mm Hypergate with a 4 port boost solenoid controlled by Motec M142 to a Garrett G30-770. The only thing is the company who made my turbo kit welded the wg flange at a 90 degree angle on top of the .82 a/r turbine housing which isn’t optimal for flow. My fk8 k20c1 made 686whp 575 ft lbs on Church automotive’s hub dyno with a di and port injection full E85 fuel system with a surge tank.
@motoiq, im not for sure if its been done or would even work on this channel but id love to see a video on how one could make a career out of what you do and how to get there. Its always been intriguing to me and id love to hear someone qualified to give a bit of there story.
Mike, can you educate me on why a turbo car might make the expected (spring pressure) boost when its cold, but loose a few PSI once it's hot? Boost/exhaust leak or spring relaxation, maybe?
trying to solve a problem like this myself right now, I will let you know once I figure it out. Do the basics first like check for exhaust and boost leaks.
It haven't been able to find any leaks, at least while the car is cold, so I recently replaced the spring. The new one was 8% longer and several shades lighter than the old one. I haven't had a chance to see if this fixes it, though (because racecar). The turbo kit is probably about 15 years old, though the miles aren't all that high.
I cant think of an actual comment that does Mike or MotoIQ justice , lets try , its not rocket science once explained perfectly , a must read Corky Bell's 'Maximum Boost'
Should have asked this question before i purchased this product but does it clear the turbo and dp on a 2015+Sti? I bought the 45mm and casing is massive.
I have a question and I need your specialty opinion. The wastegate had started pulsating after I’ve turn up the boost to from 4psi to 10psi. A 4port boost controller was install via haltech 2500elite ecu. On 3rd gear, boost is set at 5psi and after 4k rpm it’s set at 10psi. But since the wastegate pulsating started, boost will come alot later in 3rd gear and I’ll have fuel cutoff around 6500rpm. Check engine light will pop up showing a code for INJECTORS 90% CYCLE DUTY. It has a 450lph walbro fuel pump and 1000cc Bosch injectors.. also on e85.
Wait, so should the wastegate pick up from the collector laid 15° in the flow of the exhaust or away? The diagram shown showed it laid away from the flow but I always had the idea that laid in the direction of flow would help with more flow
@@motoiq ok, so like an off ramp. Branch off in the direction of flow. Yeah, the image shown threw me for a loop on that one. That's for clearing that up
So if i want 6 to 7 pounds of boost i need a wastegate that clocks out at 6 or 7 or i get a one with more (like a 12) and tune it down? I'm currently needing a wastegate and im super confused still.
When moving to an external, is it required to delete the internal waste gate? I’ve never had a turbo car, only supercharged. This stuff is really great info 💪 Once I put a 426 in my hellcat, I want to pick up a high hp JDM project.
Yes you don't run both. The thing is, do you need an external wastegate? They are for high power applications where an internal gate can't flow enough.
Would it be a good idea to install an external wastegate with an aftermarket divorced downpipe already on? Right now I’m having issues with stock turbo and wastegate solenoid creating this type of shaking of the car at high rpm. Shop told me it was the downpipe causing the issue. Have no idea how to fix this please help!
You don't use a divorced downpipe with an external wastegate, the wastegate has it's own exhaust that you can dump or merge back into the downpipe. For a stock turbo, switching to an external wastegate would be difficult and not worth it.
Don't run a compressor bypass valve or blow-off valve. This causes the compressor to surge when you close the throttle which makes the stutter noise. BTW, this isn't good for your turbo thrust bearing and causes poorer throttle modulation and transient response because you are forcing the turbo into surge, slamming the compressor into the thrust bearing, and causing the compressor to slow down. With a BOV or bypass valve, the boost pressure is vented when the throttle is closed, keeping the turbo speed high, so there is less lag when the throttle is re-applied. Then you get a hiss or whooshing noise when you let off the gas.
Good video, however I believe you need to disclose when a video is an ad or sponsored. Even when not an ad/sponsored if you get a product for free, you need to disclose that as well.
Watching Mike, it seems he is just seconds away from laughing, but still stays serious and on topic. Love watching his lessons.
Love listening to Mike about anything.
Yep, He always looks like hes about to bust out laughing!
Without a doubt, one of the best.

You're definitely getting better with your delivery....Looking back at your first few videos.
Mike is great...loved watching his Subaru related videos, I learned a lot listening to him.
Garrett always doing great things 👍🤙
My favourite forced induction talk is when people think that a BOV is the same thing as a waste gate lol.
Good knowledge coming from this guy
Mike you are so smart. Thank you for this technical information.
i say this all the time 😂 he looks like someone off camera is trying to get him to laugh. love the videos keep it up!
Natural teacher. Excellent understandable info. Thanks 👍👍

I feel like I really learn from these videos thanks
Subscribing for the co-starring fly... And the awesome information... Thank you
hey ive seen this one before
We accidentally published it before all the edits were done! It's slightly different now :)
My FC came with a Hitachi turbo that had a relatively small wastegate and once I out the aftermarket exhaust I was getting the boost creep
This dude is the GOAT
Great vid. Thanks for all you do.
That Garret goes crazy
Ive already seen this and i'll watch it again!

Awesome job unc!
my Favorite sensible Guy
Very educational
I want that SR5 Sport Coupe behind you in the vid. It looks to be in your way. Let me know where to pick it up. 😁. I had one at 16 yo.
Very Informative, love it
What happens to the exhaust after it goes through the turbo? It gets burnt up in the engine?
Flows out the exhaust pipe.
Minor correction but for the 50mm wastegate the graph states: .32 kg/sec... not 40 kg/sec...that would certainly be an insane amount of flow!
that's a pretty major correction
@@motoiq Well, you had the graph in there...
thank god!
Mike is a fukn national treasure.
This one was great!
I got great boost control with a 50mm HKS external wastegate.
It seems like the people behind the camera (if any, are making him almost laugh and he has this smile like he’s about to crack 🤣)
Another nice video! But why not include the new but avaliable and good electronics wastegates?
We will be devoting a whole video to those.
I'd like to see this on Turbosmart gates next also dont forget about screamer pipes
They are very good wastegates
I want to interview the fly. I wish I could be that fly on the wall!
Speaking of boost creep, that looks a lot like the exhaust housing I had to port on my 05 STI when I got a full turbo-back exhaust.
It is an 05 STI turbo
Another cool thing is..Garrett paid me alot of money for this. :)
We are cheap.
Great easy to understand video, this guy always looks like he is about to burst out laughing 😂
What made you stay internal on the awesome GD STi you built?
It was big enough to do the job bairly and less crap in the engine compartment. An external would have worked a little better at this power level.
I couldn't get 5 seconds into the video before he beat me at the "Hold your Laugh in" Game 🤣
I do want to see more of Mike doing videos with his new stupid co-star fly....hahahaha had me rollin there.

Do you ever use water/methanol injection fir your turbo builds mike?
Yes
I learn so much from asian guy smiley!!!!
Why you re-uploaded the video?
There were spots where the screen went black and spots with no audio so we had to re do it.
Do the springs lose tension over time due to the heat?
They sure can!
All metals have a yielding point that is lowered with increased temperatures.
He's cool non stop entertainment!
Can you talk about back pressure for centrifugal superchargers
You need less
So the "45mm" will fit on a 44mm wg flange?
If its a TiAl

What would the benefit (if any) of a water cooled wastegate on a mildly built , daily driven street car such as an STI?
If your wastegate was in an area that has little air flow and a lot of radiant heat it could help life.
Awesome 😁🤘
Between Garret and Turbo Smart, which brand is of better quality for performance and durabyliti
They are both good choices.
and best . ? is for a garret g25 -550 . for 16 psi max . . is necesary 40 o 45 mm . 370 -400 hp
g25-550 45 is totally safe
