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
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 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.
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
You can't turbo a single cylinder so many people on TH-cam have tried with no success boosted boyz couldn't with efi and there abilities to tune and your blowing all the fuel out of the carb back into the tank it's not a blow through carb best on the suction side of turbo
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 ?
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
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 !🙌👌
You're making great content and I would try a stronger fuel pump keep up the hard work
It my pay to add a thicker base or head gasket like most turbo builds to lower the compression slightly.
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 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
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 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.
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
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
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 !
If you get a silver chain it’ll add some horsepower.
Hi, am I missing something ???????
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.
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.
You need to find yourself a good person to weld or your gonna have to master the techniques of electric mig welding. It can be done joe! Max heat, maybe 6 or 7 on wire speed. Watch the puddle
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 👏
It’s been fun to watch and see you work through the issues. Best of luck and hope there is a next video.
Close the gap on the spark plug ..the boost is causing ignition to brake up...gap to .18 - .20
After watching this series I really want to turbo my 450 😬😂
I reccomend you don't unless you know how to do it right
Why!? Just why!? Dumb idea for a quad.
@@Davido50 i have a 450 dirt bike, not quad
@@masonnutter6718 yeah...lol
@Rossi Carmichael I know
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?
The rear axle is bent or your tires are not balanced because when you give it throttle everything is bouncing
Jojo this is whats up. Innovation and the process of trial and error. Excellent video my guy.
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
Was extremely painful to watch. 😂😂😂😂😂😂😂😂
Yeah it looks like when it’s ramps up boost it’s not getting enough fuel. That’s why it will hit a good lick and then the power kills. Because the boost starts to be too much for the fuel. Now I may be wrong I’m no expert that’s just what it looks like to me.
that's exactly whats happening and that's exactly why he needs a 1:1 FPR with a return line
Now you need to add about 4° of ignition timing and tune it some more. Sounds like it is losing fuel when you are in the middle of doing a pull so id say it needs more fuel
Smh. Man a hell of a way to ruin a perfectly good bike. Smh.
I guess u didn't see the bent left rim or something wrong with spacer bolts. I thought it was bent axle but it look's straight 10:23. It has to ride like riding a bucking bronco. could also be bad wheel bearing i guess also?
i bet the neighbors hate that exoust
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!
Old mechanic here... I know what your problem is. Your fuel pump is only making about 4psi of fuel pressure. Once the turbo is making 5psi or more, no more fuel can get in the carb, and you're running out of gas. Yes, even the float bowl gets pressurized with a blow-through turbo setup.
You're going to need a boost-referenced fuel pressure regulator, and a better fuel pump. And even then, it's a huge pain to get the fuel pressure regulator set up right so the carb stays full, but doesn't "push past" the float and dump fuel out the over flow.
And get rid of that extra fuel dumper that you added. Those are bad news, never work right.
You can't just slap a turbo on and go, it needs to be tuned on a dyno, they'll know when afr's are out of wack and make it run smooth
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.
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
Everybody thinks there a professional in the comment section🙄 all I got to say is it’s looking great and keep it up.
You need a afr gauge. Weld the bing in the pipe 12 inches from the head Get some good fuel in it. Last thing want us detonation
Put a better pipe on it for better back pressure
U keep reving that thang 😅😂😂😂...ain't gonna make it better...need way more fuel....and throw some race fuel
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
Its running out of fuel when boost increases over fuel pump working pressure. You need highpressure fuelpump and malpassi fuel regulator for turbo carb.
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 way you have the carburetor is going to make the quad run bad. Your forcing air threw the carb and since there is no vacuum the carb is only working bc you have that fuel pump. It’s forcing fuel threw it which isn’t how a carb works. That’s why it’s running that way and it sounds funny
That’s your fuel stopping and you getting straight air that’s why it’s cutting out
Turbos isn’t making any boost at idle
It’s smoking bc you didn’t clock the turn drain and it’s just collecting in the turbo
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. .
That's sweeeet, May need something to meter more fuel in as you get on the throttle.. Sounds pretty lean when it gets going
Update, Made it closer to the end.. YOU GOT THIS 💪
Update, RIP! Hope to see it again!
come on dude really, NO you cant hear the turbo or the wastegate, shits not working and NO power increase, is this a joke??😂
Looks like the rear axle is bent a bit, or is it something else?
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.
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.
YOU CAN SEE THE WHOLE BIKE SHAKING FROM THE AXLE BEING BENT. NEVER RUN A ENGINE LEAN LIKE THAT.
Honestly this video just proves Hondas reliability is insane
Glad you are going thru the r&d for us, this saves us some pain if we try it ourselves.
Wish you would have installed it on a more powerfull bike like the trx 450r or yamaha. But nice video!
OK, although you are on the right path, you definitely need some more gauges and some basic things to do:
I don't know what carb you are using and how much psi your fuel pump can produce or if it is enough to compensate the turbo pressure, but you need a fuel pressure gauge and a fuel pressure regulator. Connect the regulator with the turbo pressure so it gives the right amount of fuel pressure to the carburetor. I think the engine surges you experience are caused by low fuel pressure to the carburetor.
But most important : you need to have the correct oil pressure!! 2 to 3 bar pressure is mandatory! Otherwise you will destroy the turbocharger. Also: oil in and out must be vertical! You don't have a good oil return the way you've installed it!
(don't hesitate to contact me if you have any questions. I'm currently installing the same turbo on a Honda cub with a lifan 125cc engine)
Remember anytime your boost gets higher then your full pressure it will run crappy also would not hurt to get a cheap o2 gage will make tuning it easy
did you plug off your bowl from the carburetor because if boost gets in your fuel will be pushed right back in your tank
run boost into that gas cap vent. use zip ties to keep the line from popping off. then you will not need a high-pressure fuel pump to come on when boost is made.
Get a fueltech nano wideband O2 sensor, the best hardware for your buck, waterproof high quality piece for tuning, and a fuel regulator with vacum on the intake for when the pturbo pressure is positive you can keep the same fuel pressure needed, like +1 bar fuel pressure for each 1 bar of turbo pressure 1bar=14psi
I agree o2 sensor, and also add a small muffler for the cc size of engine. Will be way better bud
You have the quad on reserve you shouldn’t ride with reserve on that’s for when you ran out of gas flip the gas down to the on position
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!
I dont understand why you used your perfectly fine honda atv to try turboing it but it was a really entretaining series fo sho!
Should have just got a blue bottle= NOS💨 alot less vacume lines and instant fun🤙
bro my advice was a prescription on how to make it work, not a suggestion lol jk but really all you need is a plenum and a fuel pressure regulator...everytime the turbo is hitting more boost than there is psi of fuel pressure it cuts out..what did you think was gonna happen when it's leaning out and u keep hammering on it....just order a $40fpr and find anything for a plenum...and you probably just fouled the plug there I doubt it's blown up
Hi, he did say there was oil at the base of the cylinder head, which tends to infer 'blown up'.🤔
Put the carb on the other side of the turbo then it won't boost the carb and the Jets will work how they are supposed to
I remember being at the dunes first time i saw one of those. Dude was smoking all the banshees with ease!
how to blow up a perfectly good 400ex engine....
And having fun doing it.
How to cry on a TH-cam video over something that’s not yours.
Eeeeh you can’t blow it up, it’s a Honda. Indestructible man 😂
That’s the whole point, blow it up, rebuild and keep blowing it up. Same way when you go trail riding, you flip or role, come back home repair and repeat
Hay I also live in Wisconsin and I have a Honda 250 ex, I love people do shit like this
That's awesome man, glad to see another video. Good morning!
You still need to clock the turbo center housing so it gets oil supply in the top and drain out the bottom.
I would shorten the oil line to make it fit better along with the one sticking out on passenger side
Better fuel pump and a boost reference fuel pressure regulator. I would recommend a Malpassi...
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😐
What you really should do is take all that shit off and put it back like it was and upgrade some things if you want more power. No it's not "close" and no it's not "trying to" and no it doesn't "want to go" and please don't start spraying wd40 in it lmao.
Hi, very brave for saying all that but................
Don't need the injector, Just Go way bigger on the pilot and smaller on the main , i think like 85 and 160 and drop the needle 😙
Not kick you when your down, but if things aren’t right, stop and figure it out, I realize you don’t understand the problem, but still. You were rinding it way too long with it running poorly. These things don’t fix themselves
Tighten up spark gap so you don't get spark blowout.
Oil return needs to be lower than the turbo unless you are going to put a scavenger pump
Let's see whats going on ..everything is wrong 🙃
YOU NEED A BIGGER JET AND CLOSE THE GAP IN THE PLUG
Good try, but overly complicated ! No replacement for displacement.
Hi, he'll soon be on his knees, what he wants is more CC's.
You'll want to fix the turbo oil feed/return. They need to be straight up/down, not side/side like how it is. This will pre-maturely blow it and push oil past the turbine seal.
I know its been said, but you need boost increasing fuel pressure, if you have a 5psi fuel pump and build 5 pounds of boost you have 0 fuel pressure
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
Also I think your running to much boost. That engine has to high compression to run much boost I would dial it to around 3 or 4 psi. Just my 2 cents. Keep making great videos.
hey finally someone who actually knows something about turbos. i don't know who he has been listening to on here but they are wrong. Just gotta look into what boosted cars do to their engines and guaranteed lowering compression ratios is the absolute first thing.
Can u explain all the tubes hooked up to the carburatrr to turbo. I would maybe do this to my 400ex but the only part that's a little confusing is all the lines that are hooked up from the carb to the turbo
Hi, go back a video or two and he explains, i believe it was about equalising pressures in the carb.
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
Gap the plug smaller and different jets and you’ll be perfect. A wideband will show you exactly your afrs.
You should put a actual muffler on it
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!
Bro were the frick is the mufler
You should get an EFI system for it. Way better for tuning with boost and will aslo make more power because, well, tunability. If you get a self learning one like @CarsandCameras did, it will adjust for boost.
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.
Play with the plug gap. When making boost you will blow out your spark. I would bring it down to 18 to 16 thou.
It sounds like a turbo Lawnmower 😅
Hi, at the moment it sounds like a knackered lawnmower.
Spark ⚡️ plug gap has to be a lot less with boost, hotter plug also is recommended over stock. And high octane fuel is needed or it will detonated and sputter also.
