You need to clock the center of the turbo so that the oil drain is straight down. The way it is currently, oil is sitting inside the turbo and passing through intake and exhaust seals. Hence the amount of smoke. Adjust the wastegate so that it’s always open until you get it running right with the way the piping is setup. Then slowly adjust the wastegate 1lb at a time until you reach the desired psi. I’d hate for it to happen but a bent rod is in the very near future otherwise. Looking forward to future videos.

[@jessemurray1757]

and it will because I'm fairly certain he won't heed your warning.

[@petemartus8876]

[@bradwilliams5242]

Oil turns to foam and doesn’t drain to good

[@jbj198840]

Part 3 coming “Uh oh scattered the turbo 400ex guts” 😂

[@WOTSmallengines]

Yup.. that poor motor.

[@wheelhousegarage2940]

Gotta clock the drain of the turbo down that’s why the oil is pushing back into the turbo

[@jimnorcross2515]

I agree

[@wheelhousegarage2940]

Might also need a small scavenge pump for the return if the turbo is the same level with the tank it will back feed to the turbo can’t tell by the video of the heights if anything just run a can underneath the quad to test if the drain is the problem with it smoking as well as the feed position

[@mattoaida]

True, but I think for this application it's fine. This boost system is Jerry rigged

[@Abyss955]

He should probably get a fuel injection system

[@alexsharp2314]

I love that your giving it a go but there are a few things to change. The oil lines need to be as short as you can get them. If the drain goes up you need a scavenger pump to send it back to the tank. The turbo needs to be clocked to in at the top and out at the bottom. You need a flair on the boost pipes otherwise under full boost they will keep popping off. I hope this helps you and I can’t wait to see it running properly 👍

[@motoshack1031]

One thing I’ve not seen people mention is you really need a fuel pressure regulator that runs at default around 3psi and goes up in pressure at a 1:1 ratio so for example for every 1psi of boost pressure you’re getting 1psi extra fuel pressure, not to mention you need a good flowing electric fuel pump that makes at minimum more pressure than the turbo ever could, your fuel pump could make up to 80psi for example but the fuel pressure reg would limit the pressure to boost pressure +3psi so let’s say you get on boost and you make 14psi of boost the fuel pressure reg would have you running about 17psi of fuel pressure to the float bowl and as you come off boost it would drop back down to 3psi, I hope this helps! 🙌

[@Dm-cr5lk]

Think the fuel boost regulator only works on fuel injected systems with a return style system. That’s how it is on my mustang supercharged. It cuts off the return and spikes the pressure to add fuel instead of bigger injectors.. don’t think work on carb

[@KrustyQuad]

This is exactly what he needs and the only way to do it ( that I know of at least).. with the fpr setup there is also a return line so fuel is constantly flowing in a loop... this is also why he won't need to increase the jet size by much if any at all, makes tuning and dialing in the setup much easier

[@motoshack1031]

@@Dm-cr5lk Yeah it works the exact same way as fuel injected just at lower pressures and yeah it needs to be a return style system as well!

[@motoshack1031]

@@KrustyQuad Yeah the only reason I know this is as a child when living back home we had a Renault 5 GT Turbo which used a carb and had the same return style system as does my current side by side project, it’s uses the stock setup from the donor bike which was a Yamaha XJ650 Seca turbo which again uses that same style system, if the manufacturer’s are using it then it has to be the best way! 👍

[@owenspeulstra2741]

I hope he sees this and tries it

[@robland6118]

Also this may help or may not as far as gaskets. Kinda surprised you didn't already know this. It's fairly easy to make a gasket. My uncle showed me many years ago before he passed away how to make them. I didn't have a gasket and couldn't get one at the local auto parts store. He grabbed an old 12 pack Mt Dew box and grabbed my thermostat housing and a ball peen hammer. He put the housing in a vice placed the box over the housing unit the way he wanted and started tapping on the box laid over the housing. He tapped and tapped all the way around it on the edges until the edges of the housing had completely cut a gasket out perfectly. Didn't have to do any trimming or anything, it worked perfectly.

[@lbdrummer3]

That's the way my dad showed me how to do it too but with actual gasket material. They don't make gaskets for 1928 Buicks anymore lol...

[@chopfather2730]

They sell gasket material at auto parts stores.ask for it its behind the counter.all different thicness.

[@murrayminimotors1674]

Also used cardboard back in the day for gaskets worked in the 90s!!

[@jonnyonwheels]

@@murrayminimotors1674 yessir, always kept a couple pieces of cereal box around for that very reason!

[@jimmyjomney4877]

Make a video on this and tag me in it

[@patricspointofview7188]

Just a guess, but it almost seems like it could use even more fuel pressure. Sounded a bit like it would run out of fuel and then catch up when you let off the throttle.

[@bradleyflood5437]

You should definitely consider pulling top end a set you ring gap for boost to avoid breaking rings and destroying your top end

[@KrustyQuad]

That's the least of his concern here. He needs to get boost first and is missing some key things

[@acamp5468]

I think he needs to consider valve float I bet that’s a stock cam on the high rpm’s also a large fan for the oil cooler it’s going to run hot lol . Kudos for his project it’s crazy lol

[@njmxjunkie3128]

I agree fully with that. He needs to open that ring gap a little bit, however if the engines plenty worn in it might be fine. Those rings get thinner and the gap larger over time

[@Nogaroblueb5]

You might need a restriction in the oil inlet of the the turbo because you have too high pressure causing the oil to leak out from the turbos seals. You should also clock the core of the turbo so that the oil in is up and out down

[@njmxjunkie3128]

The oil pump for the 400ex pushed very little oil at a fairly low pressure, I highly doubt it’s possible to have more pressure than that automotive turbo can handle

[@jozsef6453]

Now lets hope the engine doesnt get a rod shortening upgrade by that boost :D

[@itslegit7362]

Head gasket will be first in line.

[@dayzplayer8539]

Or drop a valve

[@dayzplayer8539]

I guess we will find out tho lol ive always wanted to do this but with a gokart

[@jacoberbe2351]

Close the gap on the spark plug. Once it's building boost it might be blowing the flame out

[@reitzy69]

2 important things....major one is a fire extinguisher...bc ya just never know lol and 2 that thing is air cooled...put a box fan or some kind of fan in front of the engine...before next episode is rebuilding another 400ex lol

[@johna6968]

I was expecting a final bang and then total silence to be honest.

[@jedidaddy76]

Tip don’t put thread tape on in opposite direction of your threads always go in the same direction so it helps keep it on the threads as you tighten it

[@bradensmith888]

And use yellow thread tape for oil/gas

[@jeffplaysystems753]

When making a custom fitting next time use black pipe instead of galvanized galvanized is much harder to weld than the black pipe that’s why you were struggling welding it

[@ryangamble3351]

Should not even be welding galvanized....it's poisonous!

[@txsam2802]

I can’t stand galvanized metal, learning to weld on it sucked but was required for the class

[@jaygtgarage6489]

I would not rev it to hard u will lean it out melt piston..fuel mixture all wrong

[@elijahbaker8248]

Hay man, the oil drain needs to be pointed down so gravity can pull it out of the turbo. That's probably why it's smoking so bad, and the return line to the oil tank needs to be going down hill as much as possible to help it flow back into the tank. If the oil drain isn't pointed down it might destroy the seals inside the turbo.

[@elijahbaker8248]

I hope this helps with the build, I know you'll figure it out.

[@bubster1981]

put the drain up , down, sideways dont matter

[@User-sz2bg]

This is hard to watch, your going to get 0 gains from that turbo it would have been faster before

[@2vintage]

Why do you say that?

[@robland6118]

I understand where that is thought but if done correctly it will make a huge difference.

[@Zionikk]

If it works its still badass regardless

[@User-sz2bg]

@@2vintage it’s a single cylinder engine that doesn’t need any help from a turbo it already runs as efficiently as it can get. And the valves are closed/open opposite of each other so no boost can flow into the intake valves when the exhaust valves are open feeding the turbo, and when the intake valves do open to get boost the exhaust valves close killing exhaust to the turbo. So the turbo does nothing but sound terrible and make the motor work more

[@maxtheroofer8004]

boost doest rely on valve position, turbos pressurize intake air, via the exhaust gasses, Joe you need to Check your spark plug, and look into getting an AFR reader or device, i have a feeling that thing is running extremely lean, and being only air cooled it wont survive long.

[@downsouth701]

Next vid will be a banger literally!!!

[@440commando]

Might need a high psi oil pump? Definitely need to add at least .5 more qts of oil every oil change now because it has another oil component now

[@BraapBoyz]

I don’t know if you noticed or not but the turbo is leaking oil out the exhaust port towards the end of the video. May be from the turbo not being clocked right but usually when they leak like that the turbo seals are bad. Just something you may wanna look at

[@vinshanestrickland4179]

I'm not even going to tell you how many headaches you are making for yourself you are fixing to learn Daniel son for sure. Every thing you have done is going to bite you in the ass do some homework before you burn up everything you touched put that quad back together how it came enjoy it and read alot pay attention to detail like line material fluid dynamics drain and pressure then fuel flow to boost

[@jessemurray1757]

props for giving it the college try but you should do some reading (including the comments here). I'm fairly certain you're going to blow it up, but I'm just not sure if it's going to be a hole in the piston or bent rod.

[@seanhatch4425]

Can't watch anymore...Feel like I'm losing brain cells...

[@justinhaley2317]

If the carb doesn't work try an efi kit

[@hvalour1]

that turbo ain't spinning fast enough to blow up a french safe, and those oil lines are dodgey to say the least, and that fuel pump set up? i will be very surprised if this bike is faster than it was before the mod, even if it reaches and maintains a point where it may be deemed to be functioning.

[@owensbama1923]

When it keeps running like shit, there's no reason to keep cranking it and just keep revving the piss out of it. It's not going to miraculously start running right lol.

[@wisecampmotorcycles8258]

Looks like a lot of hassle to me. You won't get much more power out of a small turbo like that. You would gain more power from a big bore kit, bigger cams, bigger carburettor and a decent exhaust.

[@evanpics4631]

Big bores don’t gain really anything on these quads, it’s all in the porting and compression of the piston

[@wisecampmotorcycles8258]

@@evanpics4631 ok, so do some porting, and a new high compression piston, would still gain more power than that baby turbo he's trying to figure out.

[@benschlack5814]

Maybe change the name of the video to how to blow up a perfectly good 400ex

[@fullmetaljacket7]

That ain't gonna end right lol

[@AniassyII]

Very interesting Höllenmaschine 🤣🤣

[@dannytyson3278]

Man I hope it works good, very eager to see what happens with it!

[@stevetaylor9482]

Yes if you are "blowing through" the carb, the fuel pressure will need to be increased by the amount of boost you are using and the whole carb needs to be operating at boost pressure. For your next turbo project, you may prefer to start with a fuel-injected engine :)

[@BlastWorrior]

but with fuel injection it can be done from anyone no matter if he knows what hes doing, but with a carb there are not many ppl who can make it work he just needs a little bit more mods to get it to work properly. also a lot of the old us car tuners use this method since the mid 80s for old v8 classic cars and it works fine you just need to know what youre doing thats all, i think if he figures that out he will get it to work tho :)

[@Johnbruzzi4234]

If we had a moron gauge, it would be at red line, bouncing of the rev limiter,lol

[@thamenace9985]

😂

[@alexkichigin]

1. clock the turbo so it drains straight down (smoke is from oil sitting in te turbo and not flowing out enough) 2. I would most likely recommend an oil pump or relocating the oil tank

[@gtisid]

not that i doubt you joe but im,pretty sure this is going bang, dont you need cold air? the reminds me of a whiley coyote cartoon trying to catch the roadrunner with a box of ACME parts

[@KentRoads]

That dense cold air and running a turbo is probably quite lean :)

[@marcofrasso3212]

[@wellcrc-6703]

Single cylinder engines have to have a chamber for it to actually make boost. Needs to be 3-4x the cc of the engine. Ie 1200-1600cc chamber. It gives the turbo a chance to spool and then gives you a larger volume of air.

[@Elcostybpm]

Wooo love KZbin vids

[@PongbyAtari]

Here she blows I mean goes! Mr Wizard + Mechanic =? Next vid will be interesting for sure good stuff! 👍

[@corbingray9330]

I'd definitely up both jets, always better to have more fuel then not enough. Also the turbo oil outlet should be on the bottom, that will keep it from going into the impeller and smoking like it was. Definitely was better after the fuel pump but I'd still say it needs bigger jets, but I'm not an expert lol. Love the channel and the build, keep up the great work man! Cant wait to see this thing in action!

[@loljohn7228]

I think ur just sucking in oil in your intake you need a restrictor on the inlet and clocked properly and also probably charge piping leaks causing you to suck excess maverick air instead of correct air fuel mixture from carb

[@torzcheesey8613]

I just get high and watch this guy

[@chrisatc627]

Tip with the grinder, flip it over so the cutting wheel is on the right side, when it catches it won’t come back towards you it pulls away 👍

[@burtlandcastor8359]

Since I've seen it run I can tell it's def pushing oil past the turbine. You NEED to clock the center vertical, it is currently horizontal.

[@adiel_01z]

Omg I’m laughing when u got scared cuz the shooting flames 😂😂

[@brianmike285]

Another problem is it that is not the original carburetor and you are using a cheep eBay or Amazon one it will give you all kinds of issues.

[@swere1240]

might work better to get a ecotron small engine efi kit for it and make it fuel injected.

[@dannhisbikes8013]

it will never run good with blow through setup on carburetors. either get a fuel injection kit, or make it draw through with the intake being as close as possible to the engine

[@blasterman5063]

Do you think it will work on a 2 stroke

[@KentRoads]

Hard to do as there's loads of places to lose pressure

[@MM_in_Havasu]

Clock the center of the turbo so oil feeds straight down and drain is on the bottom. It is over-oiling the turbo because it is being forced out through the shaft seal.

Please don't blow it up. I was scared it was gonna blow up when you were reving it hard. Try to get the jetting somewhat right. Bring a lot of jets with you. Have you ever considered an AFR reader? One that plugs into your exhaust?

[@jonnyonwheels]

It’s definitely making boost, just watch the intake(charge pipe) boots flex/swell when you rev it up!

[@vintagekuz7567]

I think those charge pipes are going to blow apart at the rubber fittings when under boost. I think that’s a weak point as well, needs to weld a bead around the metal pipe to give a lip for the clamp to grab.

The T fitting in the oil line needs to be rotated once to the right that way its in line with the oil line and the center of the T goes back to the turbo.

Or better yet, get rid of the T and run out to the turbo from the pressure side of the cut line and return to the other side adding the turbo into the existing loop instead of creating a second loop with very little pressure.
