Turbo Kubota test start up
Вставка
- Опубліковано 4 лют 2021
- Well guys for those of you that noticed something isn’t exactly right. The GT15 wasn’t able to blow the red cap off the turbo outlet even at full throttle. The GT15 may just be to big for the D750. Next we are going to inspect the waste gate and exhaust to make sure we don’t have any leaks.

My wife looks at me like, why you like watching these engine stuff? She doesn’t understand...
Same. From malaysia
Same from india
Same from Colorado, USA
Same from Germany
Same from Australia 😂
Where did you buy that flange going from The tractors exhaust port into the turbo
Hi sir? Where did u connect your oil hose from engine to turbo and back to the engine?
Very nice
I think the turbo's a bit too big for it?
it may get a healthy boost if it has a Kei Truck Turbo
What good does this do?
What kind of hp would this generate?
Spool spool stustustustustu
Did you ever get this turbo figured out. We have a pulling mower with same motor and I'm thinking about adding a turbo because I all ready have the fuel turned up
Check out some of the other videos on the channel. We have a few videos of the turbo Kubota including one making boost. Unfortunately the Amazon radiator failed (spraying coolant out of a fin point). She is going to probably get a custom manifold, aluminum radiator, and maybe a intercooler in the spring. Funds and time permitting.
@@cbr600rx7 friggin awesome can't wait to see the updates🤟🤟
Please walk us thru your turbo install
What turbo gave the desired results and list the mods
I have a donor going into a Sami that could use this treatment
Thanks for posting
boost side not connected shipping cap still on compressor outlet
What is the name and number of this turbo?
knock knock you put a turbo on it, will it last or not? do not hear the high winding of a turbo too bad. Maybe try a Cummins turbo, it is massive.
What’s size is Kabota engine
Hello, can you tell me what is the tightening for the cylinder head please?
70 nm
Do you have power more? What about cooling for engine, is it enough? Why turbo on exhaust?
All turbos are exhaust driven. The factory cooling system is plenty but aluminum upgrades are also available for your radiator if need be.
@@cbr600rx7 Thanks!
How do you run the oil feed/return lines
Off the oil sensor port. Just add a tee and you can keep the sensor/gauge and add a supply line. Return is a little more tricky and depends on where you mount the turbo.
Another thing factor you have to look at is, the red cap is on the intake restricting flow and the exhaust is wide open. If you make the exhaust smaller it would build boost way easier.
That is incorrect.
you want to restrict the turbo as little as possible and have the larges possible pressure difference between the inlet inducer and exducer on the turbine housing.
@@Mr.Engineer. that is incorrect, you want to have the same amount of back pressure as boost, 10 psi boost you'll want about 10 psi of backpressure or less if you can maintain boost levels.
@@cs-gj3yf Read it again, you want the highest possible pressure drop over the turbine inlet and outlet.
Unless you have a leak it is impossible to have lower exhaust manifold pressure than inlet pressure.
So, you do not want a restrictive exhaust after the turbo and it also helps to have a less turbulent exhaust manifold design before the turbo turbine inlet.
@@Mr.Engineer. its called a wastegate, again, if your making 10 psi back pressure and 5 psi of boost, you want to drop 5 psi of back pressure. its the reason all the diesel guys want wastegates in the exhaust manifold before the turbo.
Red cap on the charge pipe outlet.... Not the "Intake". Clearly is a test run, as stated in the title.
My wife is just the same haha
Disable the wastegate!
If its not a turbo engine its not gonna be reliable . Turbo have stronger internal . Even just the fire ring have different gap . If the 2 end toutch it will expand in diameter and jam into the bore cylinder . The top piston will pop and make metal soup .
Turbo many and I mean many non turbo engines both gas and diesel and never had a issue. There are guys running double digit boost on these kubotas at double the stock horsepower on completely stock motors. Keep in mind on a stock diesel you normally see a decrease in EGTs initially until you start increasing fueling.
It looks like it doesn’t spool it very well
You are correct the GT15 with 0.45 AR was a little big. We are going to a smaller turbo now that may be to small lol. Truthfully if I could do it over again I think a GT12 with around a 0.32AR would be about perfect for a D705-D750 running stock RPMs and fuel. With that being said the GT15 would probably work well for modified guys turning higher RPMs and more fuel.
С турбинкой веселее....
Custom or can you purchase that setup?
Considering fabricating some. Unfortunately the GT15 was a little big for the D750. Resizing to a RHB31 which should allow the turbo to eventually fit under the hood.
I don't think shes gunna spool lol
That’s why we went down to a RHB-31 lol. It would probably have worked on a hot pulling set up with a lot of fuel and rpm. I think. GT12 with something like a .35 AR would have also worked.
go with a gt12. gt15 is way to big. thats what super limited garden tractors use and they make 150+hp
I agree 100%. I just had the GT15 and finding a cheap GT12 is kind of hard. I would recommend the GT15 for the hard core pullers who are running a lot of fuel and rpm.
@@cbr600rx7 yea, i got the d600 and im bout to put compounds on it, its making 30 psi as of right now and sounds super mean. turning about 4200 rpm, the gt15 is good for stock d1105's with the fuel turned up a bit.
@sourand jaded i ran a kp31 and a billet gt15, made 40 psi, going to the single gt15 after teardown.
I use a MHI TD015R on my D722…. Instant spoiling & 15psi w’ welded gate 🤙
@@mhz-yn9gh yep, although compounds are superior for these little engines
А куды она дует?
Where you live
I think he is from USA
Turbo!!!? What the hell for? Mine has worked for years without!! Too big anyway!
turbo ads performance
@@cs-gj3yf it’s a frickin lawnmower that’s all!! Performance????!
@@gregorypowell8297 its not a lawnmower, its a compact tractor, i have a '85 cub cadet turbo diesel, im pushing 30 pounds of boost through the motor and its a smaller tractor/turbo then this, look up "limited pro stock garden tractors"
@@cs-gj3yf I know!!! I have one - Kubota also!!
I see in the comments people talking about turboing these things like it's been done and talked about somewhere? And 150hp pulling garden tractors? Do people use these Kubotas in pulling competitions? Any forums I can look at for more on this?
I've got a 6100 and a 7100 and planning to swap a 7100 engine into a tiny skid steer. I've got plenty of turbo experience on cars but haven't done much with diesels yet.
Yes they are used in pulling competitions, look up limited pro stock garden tractors. They use this turbo for 50~ psi boost. I have a kubota d600 with a turbo and it makes 13+ psi. But people use kubota, yanmar, cat, etc.
You have the waste gate line in the wrong spot
That’s the way it came out of the box and it didn’t matter since the turbo wasn’t making any boost with stock fueling/stock rpms. Sometimes like a GT12 with a 0.35 AR would have probably been about perfect.
that turbocharger is WAY too big for a 600cc engine. It will never spool at any levels that are needed for power increase.
No it ain’t I use it on mine it spools uo fast
Don’t be envious
It’s a 750cc engine. With more fuel and more RPM especially for a compatible puller the GT15 is probably about the right size especially with a smaller AR. For a work tractor something like a GT12 would on a 0.35AR would probably be better.
Actually its called a d950 because its a 950 cc engine.. so boom put that in your turbo and smoke it.
thats oversized turbo
Za duża do tego silnika Załuż od 1.3 cdti
You're gonna tear that poor turbo to shreds before it even feeds your engine, revving it up with the compressor outlet capped
