With all single cylinder turbo setups u need a boost reservoir 4 times the displacement of the engine in volume, between the turbo and the inlet of the engine. Reason being unlike a multicylinder engine a single cylinder engine only pushes the turbo once every 4 phases when the exhaust valve is open and only takes boost in every 4 phases when the inlet valve is open. Inbetween phases the compressed air bounces back and forth in waves literally stoping the turbo from spooling. That is what a boost reservoir stops from happening. You can see it happening by the boost gauge jumping up and down.
You can't tell red beard that, he's got more money than brains. He's made this video for more views on his channel. But yeah, the turbo isn't going to work. Not enough exhaust pressure.
it's not just single cylinder engines, all turbo charged setup can benefit from having an accumulator between the compressor outlet, and intake manifold. the charge cooler and associated plumbing normally serve that purpose.
If you turn up the injection timing on it that should also help turbo spool. It’s probably about 10 degrees out of the box and 15-18 would make a substantial difference. There are shims beneath the injection pump that affect the timing. Removing shims increases timing and adding shims reduces timing.
One of those little amr500 roots blowers in a twin charged setup would take care of the lack of cylinders to spool the turbo, little blower with that turbo feeding it would be cool
Yep, the "pressure tank" aka: plenum stores additional air volume under boost which stores that extra volume until intake valve opens & gives the cylinder a bigger gulp of air because of the larger volume of stored air, Sweet!
Maybe the diesels could be your small fleet of recovery-karts for when another unit breaks down. I'm sure this thing would look pretty cool with a tow-truck theme added to it. :)
Measure a rod and see if you can find a billet replacement, then add heavier valve springs and some head work. Porting will help a lot, and you only need to blend the transition to the bowl to get good gains. Definitely got me interested in building a diesel.
The crank should be stout enough to handle higher speeds and power. I believe a GX200 rod will fit this engine but I am not 💯 percent sure. I know valve springs will fit.
How in the world did You Tube’s algorithm bring this video into my feed? Years of musical instrument and musician videos turned into winding up small engines to max output. Well, damn, I’m going to miss all the music. When I get back from Harbor Freight there will be a lot of fun happening outside! Thanks for your infectious enthusiasm and good how to videos!
The Rain Cap made it on there lol, it’s a real diesel now! One way I’ve found, on those types of rain caps to prevent the nut on the pivot bolt from backing off, due to vibrations causing it to fly apart. Drill a small hole through the threads right up agains the nut big enough for a cotter pin to go through, and then just run a cotter pin through it, and lock the cotter pin, and that’ll prevent it from flying apart.
The best thing to do to get more power is to remove the governor so that way the engine will go full send it’s OK if you float the valves and blow it up but it would be a good idea just to hear it go wide-open
Yay! Fun fo sho. An intake boost plenum with 1.5 times the volume of the cylinder displacement ( 1.5 times minimum, to 2.0 times displ.). The plenum will store the compressed air with greater available volume, in time for intake valve opening, feeding the greater volume into the cyl. More air + the rich fuel you have (black smoke) =bigger bang= mo go! See book: Maximum Boost by author Corky Bell for details on plenum design. Best turbo how-to book ever, IMHO. Love your channel, from a fellow gravy bones former mechanic/welder, Paul
With all proper turbo charger systems. Their should be a charge air cooler (CAC) to cool down the intake boosted air. Cool air has more dissolved oxygen in it. More oxygen=more horse power. I have worked for a major trucking company as a diesel mechanic. Don't get me wrong I like what you are doing.
A 1 cilinder boosted engine needs sort of a Boost tank, where the turbo feeds the boost into with a 1 way valve in and 1 way valve out for constant boost pressure into the cilinder . There are multiple video's how to do this , and it makes a big difference/increase in power. Besides that nice to see something easy build like this :))
Is it possible to add any predator or Tilson 212 performance parts to this, obviously the piston couldn't be changed but could you put 18+pound valve springs in it or better push rods?
It appears to be a knock-off diesel version of the Honda clone. It may be possible to use an aftermarket piston since it is of the same displacement as the Tilly 196/Honda GX200/Predator 212 and such. The one mod I think should be done right now is governor delete. There's a big governor gear in these dragon engines that really makes them lag slower than a buffering Netflix movie.
I just bought a diesel engine just like that one, glad to see it responds to boost. I'm not sure if I'm going to turbo or supercharge it yet. I'm really impressed with that little 3hp engine, I know its not a powerhouse but that moves really good. I'll have to go back and watch the video without any boost. Whats great about a diesel is that you don't run into any of the problems that you would with a gas engine. I actually have the amr500 supercharger that I was going to install on my 18hp Wisconsin thd twin thats on my garden tractor.
Excellent job! I love the way RBG shares the entire process of making something entirely different. I would like to see him build a kart with both of those small diesel engines with the single turbo feeding both engines. The boost may increase to a level that a single engine cannot achieve and increase the performance of both engines. I'm not a mechanic, so if I am wrong by assuming that it might work, I would enjoy having it explained to me.
You should make a low speed high torque puller with one of those diesels for pulling logs and karts out of the woods without burning up your belts on other karts
after reading the comments its clear to see you got some "experts" giving advice and saying it won't work... well looks like it worked to me and you had fun, that's all that matters some people just put themselves on to high of a pedestal, but you keep it simple and fun and thats what it all about, now, when you gonna Bring it to Brainerd?lol
Definitely needs more weight in the CVT but since the diesel what would be really cool is put all your intakes real high and cross some deep water lol good times
Hey you might try getting the TC to engage even lower, and also try higher gearing just to see what happens. Must have good torque so maybe higher gearing will be ok.
Definitely should try and put a proper little boost/vacuum gauge on there. Also, gear it taller so you don't hit max RPM so fast. you'll make better boost that way. Maybe even hit it with a little bit of nitrous if you wanna see how much it can handle with that little turbo hahaha
the smallest turbo diesel engines are the 800 cc smart 3 cyl 54 hp and the 2 cyl. maruti suzuki diesels with 47 hp . they both start boosting at 2,000 RPMs. anything smaller would need more rpms, like 4,000 rpms for a 400 cc engine and 8,000 rpms for the 212 cc chinese diesel, far above diesel engine capability. you would have to have someone manufacture you a special micro turbo that does not yet exist to have low end boost on a tiny single cyl. diesel. Not saying it can't be done, only that it has not been done yet. It would be cool if you could get tiny displacement turbo diesels with intercoolers that made super efficient tiny engies for go carts and motorcycles and things like 2-cv cars.
I think the smoke is oil building up in the turbo. This can happen if they don't drain fast enough. And I'd check the oil since it has a tank and long hoses to flow through. But I always thought that diesels are supposed to knock. If you don't hear it, now you got a problem
I still need to check out the diesel deuce, so maybe its been done...but a full up diesel build on say a Kandi frame with rear suspension, electric start, light bars, etc. Maybe a 12v turbo might even be an option if you have a charging system capable of running it (like an alternator off an old John Deere).
Diesel nerd here. Planning to compound turbo my Volkswagen. Have a suggestion, instead of putting a standard wastegate turbo on it you may want to look into a VNT. That turbo looks like a similar size to the stock turbo on my Volkswagen. Newer versions of my car came with a VNT. Look for a 1999-2003 ish Volkswagen TDI turbo. Cut it off the manifold and weld a flange on. The variable vanes will let you adjust the A/R of the exhaust housing to spool faster.
@@lamarzimmermanmennonitefar5269 bit more research, looks to only be slightly smaller than what I'm talking about. VNT with proper control will probably still work better lol
If it has a wastegate penny valve, I say weld it closed. It'll only boost to what the fuel will allow anyway! Could always stick a cheap $30 exhaust temp gauge on it if you're worried.
Awesome :) Is there any room to port the head? Would love to see if theres a couple simple things can be done to get more power. Would be awesome to see it build enough boost to run a clean exhaust. Keep being awesome, I know you will 😎
I just got 1 of these on a online auction waiting to see who first put a turbo on 1 well u guys sure did that awsome video love the content keep the gravel flying cheers 🎉😊❤
The only thing I can say is. May just one to make one change at a time so you can see the improvements. Also do some quantitative testing [ie 100ft acceleration times] not just rely on qualitative seat of pants test. I enjoy your adventures thanks for sharing.
It would be awesome if someone made a 2 stroke diesel, similar to the old Detroit diesel engines, like a mini 71 series engine, but closer to 250-500 cc range, a 250 cc single, with a 500cc 2cylinder , 2stroke, with supercharger or scavenger, with a 4valve head, aluminum block, designed to rev to around 4600 rpm, that would be awesome,
Smaller turbo and increase the spring pressure on the intake. Looked like that turbo stoped pretty quick when the engine shut down. You sure it is ok? I'd still expect to hear it whistling away with no air filter.
Need to build a mini trophy kart!!!! I’ve built a street bike powered one extremely fun and no one‘s built them on TH-cam that I’ve seen in a long time.
Gear it up, load the engine, should get more boost and top speed. That will, hopefully, make it chooch more. if ya feeling kinda crazy, buy a small camp propane cylinder, the spin on ones, plumb it in. Use it like nitrous oxide. Really test them parts.
Forget the diesel. Drop a Hyabusa engine in that thing if you want to have fun (and die very, very early.) It has 173hp and 100Nm of torque with a 6 speed tranny.
Red I’d love to see this thing on the dyno. I’m really curious what the torque curve is like without the turbo and with it. I’ve also heard some discrepancies on HP. Some say 6HP. Some say 3HP. I’m inclined to believe 3 over 6. Diesels aren’t known for HP but efficiency and torque. I saw I’m not the only one curious to see it on the dyno.
Need to mak the diesel dingo a tow truck witha winch and boom to haul the othe machines around new broken projects etc. It eould be awesome watching it roll coal pulling the project in or a wteck breakdown back to the shop
The bolt holes on the compressor housing of these vz21 turbos need to be plugged. One of them goes right into the outlet of the compressor housing and will bleed pressure off if not plugged.
You should try putting your NOS kit on it. See if the exhaust smoke clears up at all, when you push the button. You could try an intercooler, chill box, or water/meth. But I would really like to see is an additional fuel system, too inject either rc fuel or nitromethane. Use a windshield washer reservoir set up. Once you goose it, push the washer button, and spray a stream, of nitromethane into the turbo. Could use a gear change too. Might want to consider a scatter shield for the flywheel and clutch. Maybe a firewall and extinguisher. And don't forget to say a prayer, every time you get on it.
you should also slightly change the gearing on it as well, maybe few tooth smaller sprocket because it runs lower rpms, it wont go as fast and wont have as much load.
intercooler? go with a liquid cooled setup like frozenboost does...but make it suitably sized for the dingo...more plumbing etc yes...but cool factor +++ i already screen shot my diesel lovin' bro on this ... we're planning on cobbling together some toys of our own to play with...this is definitely on the list!
The closer you can mount that turbo to the exaust port the better put intake lash at 5 and the exaust at 7 the extra heat on the exaust valve will close the gap at operating temp and check your gaskets sounds like you blew one out when you decelerated on the first clip running twards the shop enging sounded different after
I saw you take the wastegate actuator off, but I didn't ever see anything done to keep the wastegate closed after that. If its just wide open and flapping around, that's going to really affect it making boost.
2 thing, first running a turbo without an air filter is stupid also because of heat explosion there should be some sometime on the intertake such as a short section of hose
I'm thinking because the loss in compression was only temporary, either something was lodged in a valve briefly or something was up with the decompression lever for a little bit.
Make sure the actual waste gate flap in the exhaust housing is staying closed might need to put a turn buckle on it cause it shouldn't smoke more with the turbo than it did before
The diesel dingo is great but need the boost gauge on the dash and the fuel/air ratio needs to be checked, it looks from the white smoke that it is not burning all the fuel which might be affecting the performance.
I bet if you were to wrap that exhaust pipe with proper heat wrap, you'll build even more boost. Those little engines don't have a lot of thermal output on the exhaust side and that tube is probably cooling the exhaust charge quite a bit before hitting the turbo.
Hey that's pretty amazing, it makes any boost off a single cylinder yes those are tiny turbos but still only having a single exhaust pulse to power it is impressive Shit! Unfortunately it's all Chinese and ya get what you pay for sadly. Awesome build guy's, love to see dumb stuff work no matter what it is? BUT it keeps everyone entertained and we all learn from y'all! Keep em comin guy's!

This thing reminds me of a Detroit now
Do they actually make turbos for like a regular 150cc Hammerhead Go Kart and if so does it actually make any kind of performance difference
What this one needs instead of a Rev counter is an Alarm clock to wake you up at the other end of the field. lol Smoking baby.
intercooler? go with a liquid cooled setup like frozenboost does...but make it suitably sized for the dingo...more plumbing etc yes...but cool factor +++
i already screen shot my diesel lovin' bro on this ... we're planning on cobbling together some toys of our own to play with...this is definitely on the list!
I want to see a turbocharged minibike
The closer you can mount that turbo to the exaust port the better put intake lash at 5 and the exaust at 7 the extra heat on the exaust valve will close the gap at operating temp and check your gaskets sounds like you blew one out when you decelerated on the first clip running twards the shop enging sounded different after
I saw you take the wastegate actuator off, but I didn't ever see anything done to keep the wastegate closed after that. If its just wide open and flapping around, that's going to really affect it making boost.
It's not going to make boost anyway.
Next up is more fuel and a compound setup 😁
This makes me want to build a turbodiesel Honda grom
It would be cool to see one of them engines converted to gas or possibly alcohol the compression would probably blow the spark plug out though lol
2 thing, first running a turbo without an air filter is stupid also because of heat explosion there should be some sometime on the intertake such as a short section of hose
I'm thinking because the loss in compression was only temporary, either something was lodged in a valve briefly or something was up with the decompression lever for a little bit.
Hell yeah tractor flaps for the WIN!!!
on 4 wheelers a clutch mod is a washer or shim between drive sheathes to make the belt ride lower , to increase bottum end and lower gear ratio
Make sure the actual waste gate flap in the exhaust housing is staying closed might need to put a turn buckle on it cause it shouldn't smoke more with the turbo than it did before
I tack welded it shut
The diesel dingo is great but need the boost gauge on the dash and the fuel/air ratio needs to be checked, it looks from the white smoke that it is not burning all the fuel which might be affecting the performance.
Thanks for the flapper
If you seal a wd40 straw inside the boost gauge feed line it will give you a more accurate recording. Less bouncy ✌️✌️✌️
I bet if you were to wrap that exhaust pipe with proper heat wrap, you'll build even more boost. Those little engines don't have a lot of thermal output on the exhaust side and that tube is probably cooling the exhaust charge quite a bit before hitting the turbo.
Hey that's pretty amazing, it makes any boost off a single cylinder yes those are tiny turbos but still only having a single exhaust pulse to power it is impressive Shit! Unfortunately it's all Chinese and ya get what you pay for sadly. Awesome build guy's, love to see dumb stuff work no matter what it is? BUT it keeps everyone entertained and we all learn from y'all! Keep em comin guy's!
Your our last Hope Red Beard! We have a 2000 Chinese gokart we need fixed hellllp
