Turbo Metro Fun!
Working on the tune after rebuilding the brake calipers. I am really considering going air to air intercooler from the present air to water. but, still a fun little car!

VNT control explained - Turbo Geo Metro
zhlédnutí 169Před 7 měsíci
The most common question I get asked on this channel is how do you control a variable nozzle turbo on a gasoline engine. I hope this will help explain visually how this works. as many of you know, a variable nozzle turbo effectively has an open and closed setting with an infinitely variable position between those two extremes. by taking a standard wastegate pod and modifying it so there is a po...
Turbo Geo Metro- turning up the boost

Geo metro turbo first test drive
zhlédnutí 551Před 4 lety
This is the first test drive of the Metro with the fully forged block. It is currently on low boost regulating around 7 to 9 pounds from the variable nozzle Turbo
Geo Metro turbo Forged engine startup
zhlédnutí 785Před 4 lety
This is a fully forged block. This is a 75 mm bore with forged 8.5 to 1 pistons on top of h-beam rods. HD head gasket, ARP studs, Garrett gt22 56v variable nozzle turbocharger feeding through a air-to-water intercooler. Blow off valve is an HKS ssqv
Geo metro megasquirt tach
zhlédnutí 655Před 4 lety
The stock noise suppression circuit can trigger off the negative side of the coil and drive the tach. This is something that has eluded me for years as megasquirt has a square wave tach output.

hay bud can you give me a little info im confused on or if ya know? I have a diesel so there's no vacuum just boost so would I just hook it to 1 side and use a different weight spring for return since I have no vacuum for the return? thanks
I can feel the floor shudder under my feet on startup!
Absolutely! Will definitely miss those engines
What about the cars which lack vacuum?
Not sure what you mean. Nearly every gas car has a vacuum port somewhere
the sound of flying!
Awesome video! Straight to the point, no unnecessary blah, blah blah. Thank you!!!
Beauty ! and this Guy got golden hands !!
Dont know how many times i fell asleep to that sound. The only plane M Douglas got right. Miss them 80s.
MD-11 still going strong with cargo airlines though. Also do you include the MD-90 and 717 (MD-95) in that category?
1.3 8v? Or 1.0 6v?
10:53
That's actually impressive acceleration for those. I had so much fun in mine.

The "Mad Dog" still flying
bro do you have instagram? I want to talk to you privately
How about shutdown too?🥺🙏
Can you do a 4kpot fuel enrichment circuit like the last metro where it makes that noise at 3krpm?
Hey are you still running the vnt turbo on this car? I'm planning a project in the future with a vnt turbo on a gas engine but I'm concerned about it spooling to quick at low rpm and causing high cylinder pressures and knock down low likewise boost creep at higher rpm due to the vnt's lack of a wastegate and the engine i plan to use putting out a bit more exhaust gas up top then the original engine the turbo came from does, I'm also curious about the lifespan of a vnt on a gas engine as I've heard they don't last as long on a gas engine and that's why they aren't used as much on gas engines. Tbh i don't even know if these are concerns to begin with but i thought I'd ask someone with experience.
I sure am! Runs like a champ
Have not had an issue with the vnt. If your egrs are OK, its not an issue
@@southwest82 Awesome, thank you so much for the response!
@@theking497 not a problem. I'm debating on doing a video at some point in the future on the VNT operation without a electronic controller. I get many questions about that. Truth is with work and a young family, I really have not had as much time in the shop as I used to. In a nutshell though, I adapted the Garrett GT 2256 V for this application. I used a vacuum actuated boost controller from a Volkswagen TDI which I modified
@@southwest82 That would be awesomely helpful I think since there isn't much information on vnt turbos on gas engine. But I do understand life and other more important things gets in the way. Thank you for responding either way :)
Back when jet engines were loud and layed down the smoke...I miss it from a 737 pilot.
These JT8D engines used on a Boeing 727-200 and a Boeing 737-200 aircraft.
The md-80 has the newer JT8D-219 engines. The have a very different sound than the older variants like those of the 727, 737-200, DC-9. Those older engines were way louder even with a hush kit.
Do you still own it? If so, when you get ready to sell it please let me know
Yup I have it, def not for sale
@@southwest82 I can understand why. I’m glad you’re enjoying yours
@@Doc1855 all good. I poured too much into that one to let it go. It was my final metro project, butigjt start tinkering with it again. Need to replace the fuel pump, been sitting for a while
@@southwest82 Surprisingly those Suzuki’s (Suzuki made the Metro) were durable little vehicles.
What did you make the throttle body hat from? I want to put a amr500 on my geo.
That’s actually not much flow
I think your gay you could have made a better video
Я применил двухступенчатый регулятор по давлению. Только тогда это заработало как надо.
Awesome 👍😎
3 cylnder?
No,the 1.3 twin cam
hi nice video, so the crankshaft locking tool should also work for a B5234T4 2.3 850 engine ?
Can I use this setup when I'm convering a diesel motor? There's no vacuum.
I have a GTI motor from a Swift but don't have the fuel injection wiring .
but isnt it the same thing that vac on one side n boost on tje other so rod travels the same way. why havin vac n boost .?
When the engine is not under load/boost, you want the vanes open to allow a less restrictive exhaust. When it is under boost, the vanes will open in relation to the pressure to keep the boost at set point. It is a very simple and reliable setup
@@southwest82 Bro honestly, i still didnt understand what u tried to explain in ur reply bcuz my english is not as gud as u guys. If u can pls try to explain it one more time to me. I'll appreciate. Thank u brother. Whats vaccum's role n what is boost's role in this..? That whole vdo did make sense to me but bcuz some language problem i didnt really get it. Thank u.
That's awesome!
Can the exhaust gas pressure force open the vanes as it can on a normal wastegate?
Nice setup..!! Out of what it’s the pump?
Pretty sure it’s the same kind of intercooler pump in my 01 Lightning
Love the mad dog 80
Thank you I have been looking for a long time trying to figure this one out for my turbo project .... brilliant 👏
How would this work on a diesel with no throttle body
It won't
What are you running for a boost controller?
0:27
Hey, you showed a two port vacuum actuator that you said was from a 2.7 L Sprinter diesel....is this the one you used on your setup, I want to try this on my 1.9 L diesel Volkswagen and port it in from the boost side of the turbocharger, is the original vacuum side just to atmosphere.... you would have to displace the air somewhere?
I used a modified check valve to the line when under boost
Love this great shot of the Queen of the Skies before take off. Mad Dog is a rocket ship.
Did you use the stock 5 speed transmission that came off the 3 cylinder?
That's sick I want one
Wow loud lol
You can tell these pilots love the JT8D's to hell with the Delta fuel saving procedures..fire these bad babies up!
Good job filming this.
4:29 Is it perfect really, it looks like itll leak bacuum/boost a bit I want to build a fully mechanical vnt turbodiesel and i need a 2 port actuator to do it... Hoping this will work. Very clever simple system by the way, cheap too and no electronics
long takeoff roll but these damn things look like rockets on takeoff. insane takeoff climb performance
Might have been close to max takeoff weight so a bit longer roll and yea, it seems like the mad dog does climb out fast.
@@barryaiello3127 due to noise reg they only able to take off at 80% power which is why the long roll... once off the ground all bets are off
Lightoff @ 0:28?
Awesome video! I spent many years overhauling and repairing the JT8D’s that power these birds. My job was to build and balance the compressor and turbine modules. I loved every minute of it!
were my eyes deceiving me? wind sock sure looked like quartering tailwind
Never noticed that until now! Probably explained the long roll
me: *tries to sleep peacefully* the yard crew at my neighbors house: 11:06
You are right about that!
I put a lot of those Pratt’s internal bi-pass JT-8’s through the test cells.Let’s don’t go back to the JT-3’s, (military J52’s) Gas hog smokers mass air displacers , whooa let’s go! Every jet engine has it’s own compressor signature. What you say? Can’t hear you? I just here a high pitch sound? Grind and compress that air, let’s go! Why are there pistons? Somebody likes sitting over the leading edge or is that in the back,MD-80’s I always sit there, just a little forward of the compressor blades, don’t want to get chopped in half in case they go somewhere else.
