Hey guys for the single banger to make proper/ any boost you need a little accumulated chamber in the exhaust system before before turbo. This is because a single banger can only make pulses of exhaust to spool the turbo unlike multiple bangers have a constant exhaust.
Put a check valve down there at the engine so that the oil that has come out of the fitting doesn't flow right back into the engine. That is how you keep the line filled even when the engine isn't running.
This is genuinely one of the best episodes you've ever done. The bike is awesome, the ridiculously cool turbo mounting, the noises, the classic intercooler solos.
The intercooler harp moments have changed my life. Every time I see you (Moog) with one, it makes me smile man. From one musician to another, THAT is what makes music so important. Thank you both.
I do however am quite miffed there's not enough exhaust tuba playing, and suspension shock absorber tubular bells. I mean, whenever I work on my car and bike, they do, so they purposefully nix those sounds. Unacceptable!
Actually 13 years old but all the rest you said. I think my favorite was, I can't remember the car, but Moog on intercooler, Marty on something else, Miles banging the beat on some 5 gallon drums, and Turbo Yoda with the ONE BIG BASS bassoon pipe blow at the end.
You accessing the wrong part for oil. You need to go through the clutch cover. The oil galley that comes directly from the pump. It's basically the same motor as a crf50, 70, 110. They make tons of aftermarket parts for them. It's the same principle as adding an oil cooler. You might be able to find an aftermarket cylinder with an oil galley you can use.
@@Mooza1 that would also increase the capacity of oil and that's a good thing for air cooled bikes. I think they should also add a vacuum oil pump in line to increase the pressure. They make them for small bikes and lawn mowers. Runs off the case vacuum and some bikes have a vacuum nipple you can tap into on the intake like my drz400 its there for the vacuum actuated petcock.
@@Mooza1 They used oil cooling instead of water cooling the turbo, as did most early turbocharged cars. Oil cooling and intercooling are not equivalent.
"This is how you work out the systematic breakages. In like a system, going bit by bit to find the weakest link. This is what you taught me!" Marty, this is a defining moment.

I don't know how he makes it sound like that, it just makes a rasping noise when I try. I guess that's the difference between being a pro musician and just a guy plucking his instrument.
I remember being in 9th grade 11 years ago watching RUclips on the library lab computers and seeing Mighty Car Mods for the first time, it was Moog riding around with a car battery and a air compressor strapped to his back making turbo noises lol. Seeing that clip in this episode brought back so many memories and experiences of working on all of my past cars and what the inspiration to work on my cars stemmed from. Thank you for bringing humor and love in the world, for showing and teaching ways of pursuing passion and goals.
The air in the line is causing cavitation. You need a non return valve(1way) and fill the line with oil before installation. add extra oil to the bike motor too.
I bought a BOV from GFB for my SC300 Soarer, they were legends. Knew exactly what I needed and the part was brilliant. You could vent to atmosphere, into the crank case or 50/50. Awesome supporting Aussie for great products.
@@Kstang09 that and it might also starve the top end of the engine, another solution might be making an standalone oiling system for it with a small oil tank and a pump but again, that's too complicated for something that´s just supposed to look crazy and sound cool
It’s not going to sound cool when that turbo quits working. For what that turbo cost, I’d try it and see if it works and get sufficient oiling. If it doesn’t last long then do an auxiliary oiling system. I’m curious as to how much boost that single cylinder engine is going to produce being turbos want a constant flow of exhaust gasses. This is going to get exhaust pulses which is already by nature going to cause the turbo to speed up and slow down between engine strokes. Sure it might make boost, but it probably won’t make much and it won’t be constant. I don’t think anyway. I had a turbo go kart many many years ago (22 plus years ago), and it would make boost but it was all over the place. The boost gauge just bounced around like a crackhead looking for spare change!
Spirit of classic mcm waaay back in the day, love it! One of the best episodes in history imho, love this hack-diy approach with little to no sofistication (well besides the welding)
That bit at the end with Marty riding it and actually hearing the turbo whistle as it spun up and the PSSSSHH of the blow off valve was one of the most epic things I have seen in ages.
I absolutely love that you two have been doing this for years and you are still teaching eachother things. This is my absolutely favorite thing to watch and relax to
Posty bike is a win! The oil pressure feed for the turbo is an easy fix. Find the oil pressure safety switch and put a 'T' for the switch and the feed line, just make sure that the pressure switch is on the straight through and the feed is on the 90 degree portion to maintain proper pressure to the switch.
I don't get why people who thumbs down when watching your channel they should be privilege that you guys started from humble beginnings in your channel and have grown to be in my book and so many other people feel the same that you guys are the best in RUclips and you guys are honest. Luv USA
It needs a bigger oil pump they are just proving it works, without a no return valve at the head, a higher flow rate oil pump, or both it would wear out the engine and the turbo quite quickly because both the head and turbo will be under lubricated pretty much all the time. But a large enough oil pump wouldn't have an issue priming itself on each start and keep enough pressure in the engine while splitting the output, residual turbo oil would be enough to idle until it worked back up the line in maybe 30 seconds tops. I'm sure they will do something similar before they actually tune the air/fuel ratios for some real boost.
@@jama211 that won't up the pressure, it needs more pressure barely any is going to the turbo it needs more flow than that, and the same amount is going to the engine, which is less than it was designed for so the only answer is higher oil pressure unless your happy for it to blow up a couple of hundred miles down the road lol
Loved seeing an intercooler and blowoff valve in this build. I'd love to see what you guys do yo get the oiling working better. Most of the time people turbo little bilkes they treat them as disposable projects so either oiling, heat or case pressure are ignored. Nice to see something more thought out than the typical.
Can I please tell you of the joy you two bring? I’m a 50 year old with no mechanical ability at all, but I love all that you do and please keep up the excellent harp work and occasional bare foot inclusion. Can’t wait for my young son to grow up so we can watch these together and have him ask if we can take on a project ourselves. God help him with the little help I can offer though!
In all my years of gear head enginuity, that small turbo hanging of that posty bike is the raddest thing I've seen in a while. Even Marty's n moogs weilding of the pipes. Just pure awesome, looks mean as hell.lol looking forward to the trackday video for these things. Cheers mates!!!
Myself and my friend Kyle recently bought 50cc scooters and we both installed 100cc big bore kits, carbs, exhaust, cdi, and a couple other things, then we started researching turbos literally the day you posted the first vid of this series!!! Ironic and awesome!
Really small turbo and boost the hell out of them. Restrict the amount of boost “feedback” that goes to the waste gate and they will actually make a decent amount of boost (5 -7 psi id assume with a very small turbo). It will definitely take some work. But will be fun when it works. Just know, single cylinder engines send exhaust pulses not a constant flow so you need to get that turbo moving fast and keep it moving fast. So that’s why you restrict the “reference or feedback” going to the gate.
Read into the concept of pump head - it describes pump pressure and the ability of pumps to pump stuff uphill. In your case the oil pressure is not high enough to pump to the top of the bike. If you were able to fully fill the system so that the downwards sucking force equalled or exceeded the upwards force required (like a syphon) then the little pressure you have available would be enough. Fully filling the engine with oil would be a pretty bad idea though! Gotta increase the pump pressure, or move the turbo down. Cheers - Engineer who pumps stuff out of deep holes for a living. P.S. I take pre emptive credit for any head-related puns moving forward.
I had full knowledge this would make absolutely no boost... But by the end of the episode, boy was I cheering this little Postie on! You can do it Postie, you can make boost! Great episode! Loved every second of it.
Since the outlet of the oil line is raised from the inlet at the rocker cover, you are no longer fighting only atmospheric pressure but also the pressure needed to "raise" the oil up. Love the build. These are the projects we all want to do, but just are unable to :)
Eyyy awesome to see Moog getting on the TIG! Looks great to me. So cool GFB actually made you a custom BOV. Wonder if they'll sell more. The spooly noises at the end def capped this off so well. Please do the fuel and tuning mods and dyno it!
For that sort of thing, the cad work is a large amount of the work. actually making the parts is just waiting for CNC time. Im sure if you hit them up n said "postie spec BOV?", they'd say "postie spec BOV", followed by quite a few $'s. but yeah... I want one to.
@@arjovenzia That's why I was thinking they might decide to actually sell it as a product. Would make sense given the hours of dev they put into it. That said, they'd need to do a lot more testing and QA before releasing it to mass market, which would probably cost far more than the dev time.
@@802Garage the basic piston construction was from a different range of valves actuated by a solenoid. This was the first one actuated by vacuum. The valve was made a few years ago, MCM sat on it for quite a while.
I feel like this episode brought back a little bit of classic MCM content that has been missing a little recently. Intercooler tunes. Postie song. Well done!
Thanks for the content guys! I know you guys are struggling in NSW with COVID and lockdowns etc, so yeah thanks. Appreciate it and the distraction your content provides! Hope you guys stay safe.
I would make a small oil reservoir slightly higher than the bearing itself. And the reservoir extended low enough to pick up the oil as it comes back from the drain. Basically a small cylindrical tube. The oil would naturally circulate a little on its own because of the spinning shaft and you could change it frequently.
The flashback video to a blow off valve on a bike was literally the first video of mighty car mods i watched. I was hooked. And its amazing to see how far you guys have come over the years.
Yeah why don't they just use an electrical pump on the clutch cover or sump if it has one... Get as much oil through that turbo bearing as possible, with that dribble it's gonna run dry
So with the nearly 0.0000001 PSI of oil pressure feeding the turbo oil feed line, would it be possible for the crankcase pressure that the drain is now plumbed into, to keep the oil from flowing and also cause oiling issues in the bike as the turbo oil feed line is plumbed into the oil feed system?
Quite amazing how Moog has the ability to make music via an intercooler. Over here in the US we have ChrisFix who can turn day into night with the snap of his fingers. Almost forgot, Car Wizard can fast travel as well.
@@captainchaos0666 I have a feeling chrisfix watches youtube videos and just repeats what they say. Car wizard on the other hand, he seems like a real mechanic. And not because he has a shop, but he clearly knows what hes doing. He even explains how to diagnose problems, and he shows you how he himself does it.
World's Smallest Postie Spec BOV ... which, when it comes down to it, will probably never get used ... just not enough boost to worry about it, lol! Over the TOP, Marty & Moog ... you two are awesome :o)
those are centrifugal pumps which aren't really appropriate for the low volume/moderate pressure and the type of fluid. it MIGHT be able to work, but I wouldn't count on it. positive displacement pumps are better suited for supplying oil to bearings.
It's hard for me to put into words how much joy you legends bring me with every single video. You are extraordinary people and extraordinary friends that do extraordinary things and I just can't get enough of ya. And all those comedy bits and the subtle edits and that GFB valve and that postie song omg THAT POSTIE SONG hahahahaha I love you guys you da absolute best. This project might be one of my favorites of yours throughout all these years.
That line will just drain when the bike stands and you'll have a nice air filled line. I look forward to the glorious thrashing followed by the turbo self destructing and bits of it getting ingested in the engine followed by its own spectacular mechanical cacophony of deconstruction., epic stuff carry on.
@@rimaspazereckas2748 I don't think they where going for the clean look though, more like the cars with oil coolers hanging in front of the bumpers you in see in japan.
The oil has to fight against gravity. If the hole it was going into was so small then a gravity feed would not be enough. Now when you turn the bike off does the oil drain back out of the tube?
@@goawayihavecommentstomake1488 Gravity yes, that’s a fair head to produce for a small trochoidal pump, but at least the oil viscosity seals the rotors fairly well. Air pressure, not so sure… Air pressure is acting equally on the whole system, from the surface of the oil in the sump at the beginning, to the surface of the oil at the end of the turbee lube feed pipe. The only difference within the system is the pressure differential produced by the oil pump. 🥸✌️🍻

Correct me if I'm wrong but then the engine will lose lubrication if there's no cycle right?
You mean check valve to keep prime ?
The only issue I see with the foot (check) valve would be there won't be enough pressure to open the valve.

I’m always a fan of the Intercooler Harp solos!
Y'know, one more episode on upgrading that oil feed system to a more flow-y functional one, and you'll have an actually usable turbobike.
They make little oil pumps (kinda like in line fuel pumps) for applications like this.
This is actually my favourite project yet just because of the sheer oddness and coolness and friendship
Wouldn't the oil just drain down that pressure line and back into the crank case? You need a check valve at the cylinder head so the line stays primed
I thought of that as well. It will eventually bleed off back into the head.
Doesn’t matter it wont hold over time as a turbo with thrust bearings needs pressurised oil and good flow to keep the bearings from failing.
this
“Postie……. “ another musical gem from Moog 😂😎
You need a one way check valve in the line for the oil going to the turbo
I'd be surprised if there's enough pressure there to open a check valve
The turbo just needs its own, separate, oil system with a positive displacement pump.
9:36 is definitely one of the most wholesome best friend moments between these guys that I've ever seen. Absolutely priceless
It's been so long without an intercooler solo I forgot how many great inside jokes MCM has.
I love that the little intercooler was an octave higher than the big one! Also the posty song is choice

I would make a small oil reservoir slightly higher than the bearing itself. And the reservoir extended low enough to pick up the oil as it comes back from the drain. Basically a small cylindrical tube. The oil would naturally circulate a little on its own because of the spinning shaft and you could change it frequently.
You guys are fantastic and the throwback to the bicycle BOV is gold, just realised I seen all your episodes!
Please call it the Toastie, turbo postie 😂
Cleatus will be mad at this comment.

Dose-tie
The flashback video to a blow off valve on a bike was literally the first video of mighty car mods i watched. I was hooked. And its amazing to see how far you guys have come over the years.
"I wanna EXpLaiN it!" Had me dead! 🤣
The Intercooler bit is my absolute favorite, the more you drag it out the more my day is made
you need a pump or an accumulator to make that work. Or create a venturi effect with the oil drain so it helps suck oil up the line.
Yeah why don't they just use an electrical pump on the clutch cover or sump if it has one... Get as much oil through that turbo bearing as possible, with that dribble it's gonna run dry
The intercooler music will never, ever get old... although today it had me having 1980s playschool flashbacks for some reason.
So with the nearly 0.0000001 PSI of oil pressure feeding the turbo oil feed line, would it be possible for the crankcase pressure that the drain is now plumbed into, to keep the oil from flowing and also cause oiling issues in the bike as the turbo oil feed line is plumbed into the oil feed system?
Y’all are the same type of ridiculous as I am, and I love it. If nothing else, that little Postie is good for grins and giggles. Great job guys!!
Aaaaand there it is, "HOW much came out of our account Martin?" Moog is officially my wife.
This was a very enjoyable clip, better than all "put in the bin"-clips. Much more honest and relaxing.
Digging the tune, got a Sleepmakeswaves vibe, before the vocals broke the immersion. =]
Great lyrics though.. so much truth
I laughed so hard when you brought out the big intercooler! Loved the beautifully shot sequences with your emotive music
Quite amazing how Moog has the ability to make music via an intercooler. Over here in the US we have ChrisFix who can turn day into night with the snap of his fingers. Almost forgot, Car Wizard can fast travel as well.
I wanna trade ChrisFix and Scotty Kilmer for Marty and Moog
@@getchasome6230 Imagine if ChrisFix, Moog and Car Wizard joined forces.
@@captainchaos0666 I have a feeling chrisfix watches youtube videos and just repeats what they say. Car wizard on the other hand, he seems like a real mechanic. And not because he has a shop, but he clearly knows what hes doing. He even explains how to diagnose problems, and he shows you how he himself does it.
Not sure what it is about this video, but it feels very "real", you two seem to just be going off the rails together, and im here for it.
If you don’t like posties, I don’t like you!
Loved that !
World's Smallest Postie Spec BOV ... which, when it comes down to it, will probably never get used ... just not enough boost to worry about it, lol! Over the TOP, Marty & Moog ... you two are awesome :o)
Could you use a PC water-cooling system (pump + reservoir, passive radiator) and have it pump oil instead?
Full 3 fan RGB radiator 🤣
those are centrifugal pumps which aren't really appropriate for the low volume/moderate pressure and the type of fluid. it MIGHT be able to work, but I wouldn't count on it. positive displacement pumps are better suited for supplying oil to bearings.
Or just use an electric oil pump which are made for that
That was a thing.
I don't think anyone could be more excited than Moog on this one.
Won't the oil go back down the line once you park? The it won't be primed next time
It's hard for me to put into words how much joy you legends bring me with every single video. You are extraordinary people and extraordinary friends that do extraordinary things and I just can't get enough of ya.
And all those comedy bits and the subtle edits and that GFB valve and that postie song omg THAT POSTIE SONG hahahahaha I love you guys you da absolute best.
This project might be one of my favorites of yours throughout all these years.
"if you see oil here, we did it, with science"
"what if water drips on it because of the condensation?"
"well then we didn't do it, also with science"
Seeing the cut to your bov bike video was a blast from the past, crazy to see not only how the channel has grown has been a blast! Keep it up lads
Wouldn’t it make sense that the oil will gravity feed back into the case and then will be full of air again?
or it may create a vacuum that pulls more oil through, that might be a bit hopeful
though
The oil drain can be full of air but the oil feed will be pressurized.
I should have specified.. I meant when they turn the engine off any oil on the pressure side will drain back into the case. Not while it’s running
That line will just drain when the bike stands and you'll have a nice air filled line. I look forward to the glorious thrashing followed by the turbo self destructing and bits of it getting ingested in the engine followed by its own spectacular mechanical cacophony of deconstruction., epic stuff carry on.
"If you don't like Posties, I don't like you!" 😂😂
Nothing more Marty and Moog than a turbo nugget postie. LOVE
I just hope that feed line has a non-return valve in it.
Time to spend a little more on the $160 oil feed line
30:07 "There's a sniff of art, but actually what we're looking at is function, but only if it actually works."
Why is it so hard to read Marty's lips? 😭
Oz is prison island mate. Ozzies talk without moving their lips so the guards can't make out what they're saying to the other prisoners.
@@kentbishop2635 😂😭 Brutal.
@@kentbishop2635 Literally what it’s like right meow
mars bars and pepsi
@@kentbishop2635 yeh, the Brits are watchin
Nice Mazak lathe at GFB! Mazak's are WONDERFUL machines both to run and program!
I bet the intake manifold is so long there doesn't even need to be an intercooler =)
Would probably work better as well...not to mention alot less restriction and a cleaner look
@@rimaspazereckas2748 Restriction?
😁😂🤣🤣🤣🤣🤣👍🍻🍻
@@rimaspazereckas2748 I don't think they where going for the clean look though, more like the cars with oil coolers hanging in front of the bumpers you in see in japan.
@@robm.4512 yeah...even after leaving Victoria i can still hear dan andrews saying "get on the beers"
The postie bike is maybe not the most practical, but definitely one of the coolest vehicle you guys have owned.
The oil has to fight against gravity. If the hole it was going into was so small then a gravity feed would not be enough. Now when you turn the bike off does the oil drain back out of the tube?
Yes, it’s fighting gravity and air pressure.
@@goawayihavecommentstomake1488 Gravity yes, that’s a fair head to produce for a small trochoidal pump, but at least the oil viscosity seals the rotors fairly well.
Air pressure, not so sure…
Air pressure is acting equally on the whole system, from the surface of the oil in the sump at the beginning, to the surface of the oil at the end of the turbee lube feed pipe. The only difference within the system is the pressure differential produced by the oil pump.
🥸✌️🍻
You're spot on. It’s a work of art. If I had to pick a name, it would be 'Post-MODern'.
