Try running a boost line to your vent line on your gas cap. This will pressurize both sides of the fuel system equally allowing your electric pump to supply plenty of fuel.
This this this this idk why more people didn’t like this
Seriously would fix everything
Of course. The boost is draining the carb bowl. That's a low pressure fuel pump u got there
That should actually work decently. I came to say he needs a boost referenced fuel pressure regulator to up his fuel psi as boost rises. Not sure how much psi that pump is capable of making though so your idea would prob work better in this situation.
That is right what i tought when i Heard it stall, Just Like a Nitro engine Setup in a RC car
You were running that thing VERY lean, when the turbo starts to make boost it will keep fuel from flowing into the bowl of the carb, you will need a electric fuel pump with a boost referenced regulator that will add 1psi of fuel pressure for every 1psi of boost. This is the only way a blow try carb will work to my knowledge. Only other thing I noticed was the turbo oil drain might not be the best but it didn’t seem to be smoking much so I would worry about it right now.
Awesome project!
God bless
Exactly.
For that to work, the float bowls also need to be referenced to boost. Can't forget that.
@@kasuraga Not sure what material the float is made of but it does need to be able to handle being pressurized.
@@JohnnyAnderson1 most modern one like that honda are plastic these days. They stopped using brass a while back.
Exactly what I was going to say. Also the carb bowl needs to be pressurized as well. Or the boost going through the carb will try and escape through the carb over flow vents and render the jets useless Bc boost will back feeding through them.
It is recommended to run a 1 step colder plug when introducing boost. You also need a boost referenced fuel system to add to same amount of fuel pressure as to boost.
I agree you also have to clock the oil port so it is strait up and down doing so you should help with the amount of oil that you are burning
Also need to remove some ignition timing. And should just get a cheap EFI system and run it.
@@shawnsatterlee6035 he could always use a megasquirt 2 v3.0 bowling and grippo code standalone ecu it will run anything from 1-12 cylinders, has a built in single coil driver and can run up to 12 injectors, built in map sensor he could configure a throttle positioning sensor and be able to tune alpha N. Hardest part would just be a crank trigger which I’m sure he could figure out. Download the free version of Tunerstudio and you can get a feel for what I am saying
@@shawnsatterlee6035 Agreed. EFI would be soooooo much easier to tune.
Hook a laptop to it and reprogram it !! On a dyno, by professionals ? Can you buy a chip for that ?
Get a wideband O2 sensor bro... It'll tell you how rich/lean you're running and save some heartbreak later. Keep it up though👍🏿
Frfr a carb is harder to tune, your at a point its all tune. And check the afr screw bro!!!!!!!!!!!!! Just wanna get your attention yo. I gotta stage 2 cam on a 416cc, if it dont wanna pull up in 3ed you can do better bro, BTW I gotta 15 sproket in the front and 36 in the back so I gotta more of a top speed around 90ish and it still wanna pull up around 35 mph
And prob need more fuel to your bowl in boost
That's why he reads the plugs usually. Same thing.
@@MaNNeRz91 the o2 sensor will tell him where he's at accurately and throughout the entire rpm range and under load or not.
@@bigfootandbananaman4746 for sure but he's on a carb set-up so it's never going to be as manageable as injection systems. On that type of set up the wideband would control the fuel itself. With a carb it's going to change every time he alters altitude or weather or ambient temp.
It would make jetting easier for sure but I wouldn't want one without the added fuel mapping benefits from an ecu controlled system. Which I think is the smarter route for a turbo anyway especially in regards to boost cut-offs and oil pressure safety
You'll always get the most boost while in gear under load, also running super lean, don't fry that piston
must not of watched the whole video XD
Always best power right before it breaks he will be building that one definitely it's cool though
Man, it’s cool how you are able to make videos and do projects like these. I hope these kinds of projects support you financially enough where you can easily slide by doing things like this for a living. Best of luck!
Oh he’s probably doing muuuuch better than you might think
It’s been fun to watch and see you work through the issues. Best of luck and hope there is a next video.
As a lot of guys told you; clock the bearing housing of your turbo right!. Take the turbo off the bike and loosen the bolts holding the center section (the bearing housing), and turn it so that the oil inlet is at the top. It is very important that the oil drain port (at the bottom), is large and non-restrictive otherwise, your engine will drink oil from the turbo. There are no oil seals in there, only labyrinth seals... At first, do not try to boost more then say, 8psi. remember that @ 15psi, you will double the horsepower, in a good tuned install...
His oil drain runs uphill, they will sort it eventually. Probably going to need a pump to scavenge oil out of turbo
I think you are doing an excellent job
Taking real fails and working through them
We enjoy victory, we learn from our fails
Keep on going Joe !
That's awesome man, glad to see another video. Good morning!
Jojo this is whats up. Innovation and the process of trial and error. Excellent video my guy.
Yes! Been waiting for this
When boosting a single cylinder, your gonna want to build a boost reservoir before the intake. It'll help keep boost between the single exhaust pulse.
Listen to this man right here, this is one of your biggest problems and you do not realize it yet. That surging you felt the engine making that was because of it being a single and it has no exhaust pressure in between the exhaust strokes you have to make a big enough box to hold I think it's double the CC volume of the motor your running. I could be a little wrong on the sides but if you look into it there is a mathematical equation. You can add to get the dimensions of the box you need between the turbo and the intake.
Hey man if you need a fuel pressure regulator that’s GUARANTEED to work on a carb setup look for a fuel pressure regulator from a Yamaha XJ650 Seca Turbo, those bikes were factory turbo’d and like I say you’ll need a decent high pressure fuel pump, that little pump you have now isn’t enough under boost and the boost pressure is just pushing the fuel back to the tank and emptying the float bowl, at the bare minimum you CAN run without any fuel pump with a blow thru setup you can just run a boost line to the tank to pressurise the fuel tank but I wouldn’t recommend that as it’s janky at best, I promise though if you try either of these methods you’ll see a great improvement and it won’t break up like it is currently! Good luck! 👍
This man knows what’s up !🙌👌
Glad you are going thru the r&d for us, this saves us some pain if we try it ourselves.
Haven’t been on here in a very long time glad to see you’re still keeping up with content !!
Mad scientist! I love this! that exhaust flange floating around tho 🤣
I think figuring out a way to tune the timing will really improve this thing. I really didn’t expect it to even run this good on a blow through so way to go bud. Love it
A msd would be the easiest I think
Delphi ECU
@@onekick nope. Self adjusting/ variable cdi
Ricky stator adjustable?
With boost you have to pull timing like in a car you can hook up a computer and tune and change stuff but with a atv i just dont understand how it would work properly without a good tunable ignition system and it wasent made to handle boost you would have to stud the head to keep it from lifting and blowing gaskets
I noticed the carburetor has a rubber diaphragm throttle body needle, boost is keeping the needle from opening, remove the diaphragm or use a snowmobile carb.
The 400ex stock carburetor is not a CV carb, the slide operates with the butterfly directly.
I remember being at the dunes first time i saw one of those. Dude was smoking all the banshees with ease!
Super cool Project! Love ur videos man!
You still need to get the oil in and out set up right. The oil inlet fitting needs to be vertical and the oil return pointing straight down. The compressor and turbine housings can be clocked so everything lines up. You just need to loosen the housings and rotate them so it all lines up.
could it also be getting that much oil in the cylinder that it's not able to burn it kinda sounds like a 2 stroke
@@elcaminogaming6707 When a turbo is clocked horizontal the oil will usually go by the exhaust turbine. The compressor seal is a much more positive seal than the turbine seal. He's getting there with it. You gotta start somewhere.
I thought you would have it sorted by now. It kinda looked like you did, at first! Damn. Keep it up! Looking forward for the next one!
Biggest issue is going to be intake air Temp without intercooler it's going to get hot after awhile. Other than that it will work with some work. Great job 👏
Don't give up Joe. You'll get it running right. Just have to get the carb right. Might have to change the jet needle if moving it's clip down (raising the needle) doesn't smooth out that transition 1/4 throttle. I think those rings were worn out a bit too much for the extra pressure and freshening up the top end will help you to dial the fuel mixture in. I have faith in you and am anxious to see you burning the rear tires off the rims. Faithful subscriber Whoop! :D
Awesome video man keep up the good work you'll get it & she'll fly 👍
You should look into building a Pitot tube in the intake to pressurize the carb. You also need a pound of fuel pressure for every pound of boost because the boost is actually blowing the fuel out of the main jet instead of letting the engine suck the fuel into the engine. Hope this helps. Turbos and carbs are tricky but you will get there. I have a Yamaha RS Vector Mountain that I added a turbo on Too. Struggle bus for a little while, now it is a mountain climber.
Well done. I hope you get it figured out. Looks good so far
It my pay to add a thicker base or head gasket like most turbo builds to lower the compression slightly.
man i have to admit. I have left you a couple of not so encouraging comments. However you doing what I should be. Your videos have gotten much, as is from your comfortably. you have gotten better as a mechanic. Your information has gotten a lot better.. Good Job man.. when you 1st started I didnt like you so much. Now I approve. I had a turbo, for my raptor 686, and I knew someone that needed it so I gave it away. how Just the best place for true vacuume is manifold pressure for sure..
i bet the neighbors hate that exoust
Put a wd-40 squirt tube inside the boost guage hose 👌 it will give a smoother reading with less bouncing about
He probably would lmao
@@owensbama1923 what do you mean?
love your vids
This is a good video dude 👏 👌. I'm always wondering this too but that all looks like so much holy lol. I'd be worried about hurting the engine but I mean a little wouldn't hurt
Hey Joe. That must've been disappointing. However, when you get that turbo up and running correctly, I am betting it will be totally bad ass and worth every moment of the work you put into it. Keep your head up!! Persistence will pay off!! Dude, it's going to be sweet!!!
Your the guy everyone who gave up on their project needs to talk too
That's sick bro 🔥
Congrats on the build bro,wish i had sum like that
Everybody thinks there a professional in the comment section🙄 all I got to say is it’s looking great and keep it up.
That's a very technical setup, kudos for trying to work it out. Showing my ignorance I never saw a blow thru setup before. Back in my youth if you wanted to add turbo to a carb engine you put the carb in a sealed boost box with line, linkage, and boosted air ports to equalize the pressures inside and outside the carb so it could operate as designed instead of with a pressure differential inside to out. But I'm no expert so good luck. Lots of good work there.
Hi joe what a bummer mate but keep your head high you are doing a great job and I know you will get there wit h this hats of to you for your determination that's what makes a successful mechanic keep on doing what your doing you will defo figure it out and reap the benefits for all your hard work take care mate great content 🔧🔧🔧👍👌
Your making me think if i should do this to mine! Remember when it's cold out you run richer than when it's warm out
You will get it man
What an awesome gold thank you for doing this if that gauge is right that's a ton of boost just sitting in the garage with no load. Continuing video now.
Trial and error. Good video joe. Keep it up
I agree o2 sensor, and also add a small muffler for the cc size of engine. Will be way better bud
Probably been mentioned but welding gas makes welding sooo much easier. Great build and keep up the good content!
I was thinking the same thing...instantly become a better welder the day you use gas shielding.
Or just learn to arc weld
really love that you say you are not an expert in your videos now 😂
Haha had to! New people watching seem to think that I am lol
You're making great content and I would try a stronger fuel pump keep up the hard work
I’ve been so excited to watch this!
You will get it running proper we have faith in you.👍
Either switch your carb to a Pull Through with an electric pump, or you need to boost reference your carbs float bowl (if it's not already) and add a fuel pump too The boost is pushing fuel out of the carb atm That's why every time it gets into boost it leans out hard and shuts off after you wing the throttle open I think.
Dude deadass left the bicycle grips on 🤣
After you get it going again. Check ring gap because when you run a turbo your ring gap should be more. Awesome vid Joe you will get her dialed in.
You can wire in to the ignition switch and it wont drain battery when ignition is off
It's straight piped!🕺
If you get a silver chain it’ll add some horsepower.
Hi, am I missing something ???????
First keep up the great videos you inspired me to make a video similar to what you do should be posting it today if all goes well it’s a kx250 with low compression bought it off a guy who had it sitting in a barn for a long time
Awesome!
Really enjoy the willingness to try new things! Three thoughts for you to consider. 1. You may want to retard the timing (3-5 deg) to reduce cylinder pressure and save head gaskets. 2. You could move the clip on the needle jet down a couple of slots (needle higher) to richen up the 1/4 to 3/4 throttle jetting. 3. The fuel pump regulator may need to be referenced to boost rather than atmosphere so you get fuel flow under boosted conditions. Enjoy the channel!
that is sick man hope the engine is ok !!
Hey joe, I wonder if you doubled the base gasket just to decompress the motor it may handle the turbo a bit better, making the piston not come up as high in the combustion chamber, what do you think??
Your going to blow that motor up
I know on Banshee's the Crank Seals Have to be Glued In
Who cares that would be a new video
You still need to clock the turbo center housing so it gets oil supply in the top and drain out the bottom.
Nice vid that's awesome
Check for boost leaks to make sure your getting consistent boost and start playing with jetting she’s going lean and hitting boost cut just as is starting to lit up you got it man just playing with your jet sizes a lot lol! So excited to see this thing rippppppp
A turbo engine will act completely different under load then it will just reving it up btw
Lol who knows maybe it needs less fuel Ik that wouldn’t be right but hey🤷♂️lol
Idea 💡 your original diaphragm carburetor throttle body needle ran off vacuum. Run a vacuum line from the carb top cover to the turbo intake so the throttle body opens under turbo boost.
I’m right there with u bro. Doing a blow through setup on my Suzuki z250 and running into similar issues. Idles good but bogs down once I start to get into throttle. I am adding the same power jet you added next. Trying to get this fuel system lined out. Best of luck getting it lined out man
Looks like the rear axle is bent a bit, or is it something else?
What's up bro great video
it sounds so cool
I really like the video, I really Like the voice over to.
Great video , my ocd is my downfall the upside down gauge gave me a headache 😂
dont know what looked bent more the rear axle or the rear wheels i was waiting for it to vibrate off the stand n go threw the the garage lol
You may be able to T the bowl overflow and the fuel cap vent to the boost pressure of the turbo . Equalizing the pressure in the fuel tank ,and bowl . And keep the fuel flow the same with out the fancy boost reference fuel pump. . Yes colder spark plugs help prevent detonation / spark knock. .
Also sounds like it's emptying the bowl when the boost comes in then waiting for it to fill up again. Maybe run 2 fuel pumps into the bowl or look into a bowl-less system? Is the fuel tank pressurised?
Does your carb stil have the fuel acceleration pump stil hooked up on the carburetor
Look up boost referenced fuel systems, I think that will be the key to getting it dialed in, fuel pressure has to overcome turbo pressure, also don’t forget ring gap and boost pressure are also a big consideration
There will be no need for back pressure. The turbo builds boost pressure in the manifold aka headers, and in the hot side snail 🐌 on the turbo. After exhaust gases exit out the turbine wheel you wan it to be as least restrictive as possible which is what you did. Looks good
The rear axle is bent or your tires are not balanced because when you give it throttle everything is bouncing
Needs a low compression piston, cold plug gapped tight, and boost referenced fuel pump play with jetting and its golden
love to see your projects just kills me watching you try to ride lol when you need to change gear etc i feel more sorry for the 2 strokes haha STILL A FAN!
did you plug off your bowl from the carburetor because if boost gets in your fuel will be pushed right back in your tank
Hay I also live in Wisconsin and I have a Honda 250 ex, I love people do shit like this
So crazy 🤩
Dont give up Joe, gap the plug down, gap the piston rings, and come back stronger
First person I saw that said end ring gap😐
I did a similar build and turbo’d my Honda pioneer 500 on my channel. It was the first and still only turbo’d P5 in the world and it worked great! Little easier for me though as it’s fuel injected and easier to tune with a programmer. Hardest part was an oil system which I still haven’t got quite right yet.
440 stroker will smoke it
The boost is your manifold pressure referenced to ambient air pressure. So you won’t see any boost until the turbo overcomes the vacuum of the engine. I drive a turboed truck and just cruising around don’t see must boost. I’ll see it reducing the vacuum alot but rarely pushes past the ambient air pressure unless I’m really on it.
Easy things to try .run hose straight from compressor housing to tank then regulator before carb
Like already said, run a boost line into the fuel tank so the fuel gets pressurized if the turbo makes boost, then the carb is gonna mix the air fuel at anytime with right numbers just like with no turbo.
A good mechanic on a fool's errand, an expensive errand as well. All for the viewer i suppose, and we do enjoy!
u might not claim to be an expert but my friend u are the shit when it comes to ATVS
Now i know nothing about turbos but like
What if you made a hole in the gas tank and ran another boost line coming from the turbo to the tank? Cause then it would have matching pressure and push fuel to the carb right?
Hey Joe what did that clamp on exhaust go to on the passenger side?
? Why my kx65 boog down when throttle turnt wide open or riding it boots then it mite catch and go
I've been watching turbo builds for bikes and quads. They manifold The turbo where the carburetor usually then build a pipe off the back 90% facing fwd mounting carb there for extra thrust.
Hey look up Cars and Cameras, they boosted a Predator 420cc, and added a small BOV. I can't remember what that was taken off of, but ill look into it asap. That will also help with the boost pressurized carb
BIG POWER ON.
Awesome vid and edits and filming and toys and shop and property’s and knowledge and vehicles and riding
Great vid.u will get it figured out and c what it can do against the banshee 500.b safe.peace.
How did you boost reference the carb to work as a blow thru?
what's up with the exhaust flange just floating there need to weld the exhaust where it slips into the main
