I built a turbo banshee. Used a blow through setup. Had to pressurize the float bowl and the top of the carbs too so the slides wouldn't blow open and stick. Had to run a separate fuel system for when the motor started to make boost using a electric fuel pump , progressive pressure diaphragm that would just feed the powerjets in the carbs so at low or no boost it the carbs would function normally. On methanol at 21lbs of boost it made 168hp at the tires . Anyhow there's no doubt that you can successfully turbo a two stroke people have been doing it for a long time. Guys like tyson racing , Dan Hull, Matt shearer have all built brutally fast turbo banshees ! Not to mention all the snowmobile builders that have been doing it even longer .
Thats awesome, 168hp is nuts! I kmew theres people doing it but i dont really see anything online about how theyre doing it. Nothings being documented. Alot of the snowmobiles use special valves and/or are fuel injected. Mostly multiple cylinder stuff too. Havent seen a single cylinder be successful yet either. Doesnt mean it hasnt been done but again something different that only few will try 🤙
I've been doing blow thru mikunis by using a pitot tube in the charge pipe so it changes the atmosphere in the carb and keeps the fuel in the bowl. Just sealed the rest and use pulse pump. Then it doesn't require boost regulated pressure or anything.
@@kartnerds does that work at 20+ lbs of boost ? The amount of fuel that I needed was a lot more than a 65lph pulse pump could deliver. On a 500' hill race id burn over 5 quarts of methanol in one pass .
@@petemcpeterson6205 I've not run over 20 this way but I don't see why it would be an issue. Currently doing a 20lb build but draw thru. There's a really short clip of a gx390 running almost 20 this way on my page.
That would be one giant pulse pump to pull off that fuel delivery tho. Hah.
Wow that's nuts. I don't think my Yamaha has the slides pressurized but I guess it must. Yeah the cv carbs do vent to the bowl so pressurize them and you pressurize the slide. Good to know. The Yamaha in question is a Seca 650 factory turbo. No where near 20 psi for sure. I'm planning on doing a XR600L with a regular slide carb non cv. I never would have considered pressurizing or at least sealing the slide. So thanks for that!
Burnt pistons, burnt pistons everywhere. Lean as hell
Sounds exactly like when I lost a sleeve that goes in between the crankshaft and seal. Idle was way too high. I used a short piece of 3/4 copper pipe that fit perfectly. It's still on the bike.😂
People saying u can't turbo a two stroke? Really? So all those turbo two stroke snowmobiles don't exist lol
Turbo sucking that carb dry for sure lol, so excited for the next video !
Thank you so much for posting this video on UA-cam, to show the pros and cons of the 2-stroke turbo
I mean yes pros and cons but we can improve and outweigh the cons!
@@StupidFastJohn And what I'm doing too with the 2-stroke turbo but I'm using injection, thank you again for this beautiful video you published, I follow you from Italy
I grew up riding an old blaster like that. I ruined that motor over and over again and then helped my grandpa rebuild it. How I got 90 percent of the experience I have working on 2 strokes.
It sounds like you’re sucking the bowl dry, and I think the vibrations screwed that gauge up
Wow, fast and smart to even try to do this build. John u impress the hell outta me. Keep killing it, this video is awesome.
Thank you bro i appreciate that 🤙
@@StupidFastJohn ❤️
Fantastic video! The quality and production have skyrocketed over the years. Congrats, man. I can see you've lost some weight too, keep up the great work! ❤
Ty i appreciate that!
Best turbo video yet
Im glad i came across ur channel. Great content brother. Keep up the great work. And much love to ya from Maryland❤❤❤.
Did you up jet the carb?
It might run better with a straight pipe to the turbo, plus an exhaust off the turbo.
You also might need stronger reeds on the intake. As for cooling, you could add a small water injection, to cool the charge intake temps.
Another thing, on RDs TZRs, the have a bottle coming off intake to help with the power band.
Have you watched a channel called "2 stroke stuffing" if not he's made a super powerful 50cc engine of his own design, and has played with supercharging a 2 stroke. Dude is a Wiz when it comes to anything 2 stroke.
So nice to finally see someone who actually do it for real. Not a fake crap when carb is in between turbo and engine intake without pressure valve for fuel and.shitt claiming it's working perfectly.
Great vid John! Learned a lot
Love the videos man keep it up
love the video man, i have a blaster build im doing as well. Great learning
Dude you do some crazy shit! I LOVE IT!!!
Fr
Your on to something!!!!
I was interested into this stuff! An engineer told me that if i wanted to do this i shouldn’t put too much turbo pressure because you just slow down the piston when it comes down, because there mustn’ t be too much! I’m happy to see this!
You just gotta a fallow buddy nice! I give you my approval
Anyone who says a boosted 2 stroke doesn’t work obviously lives somewhere warm , we’ve been riding turbo 2 stroke snowmobiles for years now . They even come from the factory turbo now . Polaris boost 850 and the 850 turbo ski doo . Works amazing in elevation , it’s essentially what it’s for is to keep power at elevation. Although now they have trail versions available and ski doo even has a factory meth injection .
great video. your explanations are great for the informed and uniformed. . you def have a new subscriber
peace, eic
Love to see it I hope all goes well

Can't wait to see the next video thank you
Great video boss
Don’t give up! The Wright brothers first plane didn’t fly! Trial and error is the key. You got this
Thanks Timbone!!! 🤙
People have set land speed records on turbo 2 strokes it's possible for sure but the power band can be weird even for a 2 stroke they say it can't be boosted but every 2 stroke is already making booster in the crank case but what keeps the air fuel mixture from blowing out the engine is the pipe so you also might need to make a custom pipe
Do Swap kit Maybe it's expensive, but you won't see the problem of fuel hunger, and it's good if you make the turbo exhaust shorter, you'll get a lot of boost 🤟
Holy crap I gotta watch thus I'm gonna go get this kt100 for my go cart and I was looking at this turbo but now that someone else did something similar I know it can be done
U absolutely earned my subscription with this. I love everything about this. If we could jam this on say a 98 kx 250, my god. It would represent all my hopes an dreams
Hell yea bro I believe it will work once all the bugs are worked out, all 2 strokes are just air pumps pumping fuel and air and the more fuel and air the faster they are so I bet that turbo is sucking that bowl and carb dry starving it from fuel , you will figure it out, can't wait!! I build RC cars 2 stroke glow engines that run on vp nitro and everyone says you can't turbo them either but Im going to try it 👍👍👍
if i had to guess the carb is having trouble supplying enough fuel so try to put bigger jets in it, love the vids man
This has been a really cool build series! Im a 2-stroke guy so this is awesome. I would highly recommend however, try a different combo of main and pilot jets along with needle clip positions or possibly different numbered needles before adding the extra fuel draw mechanism. Anyways, very good job!
Thank you will do 🤙

I hope you remembered those power bands with that turbo attached might have to make your own set if those gold ones aren't enough😂😂😂😂
Lmfao!!!! I bought china gold so theyre orange 😭
Power bands?
@DarrenBoxhall yea they look almost like rubber bands it's a secret on where they go and which ones are the best but you gotta have them if you want the bike to be like a race bike
Yeah let the exhaust breathe. Two strokes are tricky with turbos. Superchragers are easier and you can get some boost out of them since two strokes rev a little higher.
I appreciate the video
John, your explanation of how a Reed valve 2 stroke works is incorrect. As the piston goes up the bore towards tdc, it creates a vacuum in the crankcase, which opens the Reed valves and sucks the fuel air mixture into the crankcase. Then, when the piston moves down the bore, it compresses the crankcase, closing the Reed valves. When the intake transfer ports are uncovered, the fuel air mix is forced into the cylinder.
I’m sure you know this, you just explained it wrong. Fun video though.
I dont feel that my explanation is wrong i just believe i missed 2 of the key timing events and discussing their relationship. It doesnt help that my wording is terrible most of the time too. I should have referred to bdc and tdc when i spoke about the position of the piston to the opening and closing of the reeds and i should have covered it in a 360 degree rotation not a "piston up and down" which left it vague enough for misinterpretation. This is typically why i dont do alot of in depth explanations because not everybody understands how im trying to get the info across.
Theres a point after the combustion dissapaits when the piston is still on the way down after tdc and opening the transfer ports when the piston windows become open enough that the reeds then open. This isnt quite exactly at bdc. It may be at a lower rpm but as the rpm's pickup so does the process and the timing of the process. This is what the piston windows are designed for, letting fuel and air into the crankcase area and up through the transfer ports to smack the exhaust air coming back in for the scavenging effect and those reeds wont close until the piston just passes tdc after combustion. I understand some of the combustion after tdc will push through the transfers obviously and close the reeds on the way down but theres a turning point when that charge is gone that the process immediately reverse's to suck fuel and air in similar to when you put starting fluid in a tire and toss a match in, if you dont fill it with air fast enough after the explosion it creates a vacuum and pops the bead back off again. This is why i said when the pistons going down because it doesnt just flip flop exactly when the piston hits bdc but it is close. Especially on a shorter stroke engine like this one.
Nice video. your gaskets you made after your done take a step up still bit to the center of all those holes and make em nice and round keep up the good work
You are the beast!!!
Hell yeah dude regardless of the full outcome it started drove and made boost that already is a huge win now to make some tweaks to get it fully running. Maybe adding some leaded fuel will help it stay cooler to maybe something to think about.
If you have a small air bleed into exhaust and a spark plug there you could make use of the unburned charge coming out of the exhaust and it would spool like a jet/ gas turbine.
2 stroke diesels are turbod but the exhaust timing is not symmetrical, the exhaust is closed early while inlets/ transfers are still open so boost isn't wasted. Overhead valves, exhaust port side piston (OP) is timed ahead or extra valve controls exhaust ports.
Now the name is fitting! Haha
Bigger jets, maybe a bigger carb and definitely a fluid filled gauge
Love this channel I am building a banshee with a Yamaha R1 1000cc street bike motor and my smartcar turbo is going to my blaster only going to turn the turbo into a supercharger
Came across your content last night on UA-cam just wondering what did you do KFX 700 I have one that I have totally rebuilt is a monster of a bike love riding it put a lot of money in it but there's nothing else out there that I rather have!
You make videos from better to better. Nice explication for everything 👌
Keep it up like this ✌️
Congratulations from Portugal 🇵🇹
Thank you. Clever for sure and gives me confidence for my project. Semper Fidelis thanks brotha
What about a second carb at the end of the system? Rig it to be wide open at all times and jet it down so it doesn't do much unless you open up the throttle and actually sucks the gas from carb 2
GREAT BUILD! MIGHT HAVE TO DO THE SAME TO MY CHINA 2500CC 4-STROKE. THEY SELL ALL THE FLANGES ON EBAY AS WELL.
Bro, my buddy had a turbo banshee that worked great, they just installed an electric fuel pump that came on during wide open throttle. I think they just used a momentary switch fabbed up to the thumb throttle. Might want to try something like that. Good luck, looks like a fun project.
You have to do one with Nitrous, run it through the oil injection port on the carb.. should be easy, was an idea i had but never tried. Complete me 😂😂😂
Probably help to get that turbo closer to the reeds with the carb.
I agree but it was literally impossible to move the turbo up without cutting the frame 🤔
@@StupidFastJohn that's the tuff call bro
Ski-doo makes a factory E-TEC 850 two-stroke on their summit mountain sleds. The motor makes over 165hp at 8,000 feet of elevation! So yes you absolutely can turbo 2-strokes. Modern EFI makes things a lot easier, and advances like transfer port and direct injection make them a lot more efficient and emissions friendly. The world needs more two-strokes and turbos!
Love the video mate. I think you need to do some jetting to the carb though
20mm hole saw through the main jet
Cool video, down and dirty lets see what happens kinda shit😂 i love it!
Had the same problem with my Arctic cat 440 had no muffler on it. It was straight piped like your bike got a custom muffler made for it and a a jet kit and now it runs like a top had the same bogging at low to mid throttle wide open it was fine
Great video thanks
Now can you turbo a 4 stroke utility quad ! I would love to do this for my Suzuki king quad 300 4x4 which has little power stock
My brother.... Im serious speechless i hope you read this if not it's totally fine lol. Oh boy this can drag out but here we go. I had a best friend from highschool we where crazy about cars hondas Mazdas all imports lol. Anyway i never knew about the Yamaha blaster until he showed me his dead in the garage covered up with all kinds of stuff almost couldn't see it lol. We long chats about it and how 2 stroke is so close to rotary engines in some way and i was hooked. I ended up going out and buying a used blaster showed up to his house we all drove it all night had a blast. He basically made him pull his out and bring ot back alive and we would always go off road ripping it together on our blasters. The moral of this story he would always tell me how he wanted to efi turbo charge it and i would laugh saying thats not a easy task. He would always mention to me about his aem standalone he had for small engines he had all these bad ass ideas man to efi turbo it. Sadly i lost him November last year and its so been very tough man but i ended up buying his blaster that we rode together from his family to bring it back to life 😢 he was 38 we where born in the 80s. Anyway just wish he could of seen your attempt he would definitely appreciate it.
Im sorry to hear that man and im happy to have hopefully brought back some good memories for you 🤙🙏
You sure did my brother I appreciate it
Seen turbo and banshee i click and subscribe 😂😂😂
The choke helps alot lol
Won't be long before that's toqdt
I wonder if tapping that helper jet directly intake flange and adjusting accordingly. Good look be waiting on next vid
U drilled and tapped on the intake side with it bolted up?
Skidoo makes a turbo two stroke. But there is a lot more to it than you are thinking. Two strokes pull the air from the crank case, I think bombardier sealed the crank case and an actually put valves in the head to seal off the jugs to stop compression leaking out the intake side, they also had to fuel inject the the engine too. Super cool engine, you should take a look at it for some ideas.
I think you need to look at the two stroke more like a diesel set up to work better
I once put a 500 Yamaha tt engine in a blaster 90 mph plus 😅
Tip. The pipe from the turbo to the engine needs to always travel down hill the entire length. Other wise fuel will puddle in the intake pipe and cause alot of odd running issues.
yeah I like Matt(dirty garage guy) but he was way off on the 2 stroke/turbo video. I have built multiple turbocharged snowmobiles. draw through is the best way with a carbureted engine so you dont have to worry about the boost making the carb piss gas allover.
You needed to use the mini eBay supercharger. I think that's why those 2 stroke diesels used them instead of turbos
I would eliminate the expansion chamber exhaust pipe direct mount the turbo to the cylinder also use gravity feed from the oil tank (0w20 synthetic oil) to the turbo and use the pump to scavenge return the oil to the tank also jet a larger 35mm carb and run E85 for the cooling effect use steel reeds for heat and pressure resistance from boost you will also need to port the cylinder to take advantage of the extra air flow from the turbo and accurately measure the flow through the engine to match the max wastegate boost pressure an air to air intercooler between the turbo and intake will also be needed with high temp silicone isolator boots to keep intake temps in check
You're the first video I've seen suggested for me with ebay and automotive stuff. What are your thoughts on them giving into the EPA?
Once you have it worked out, you should put a turbo on the three wheeler that was earlier in the video.
Did you get the metal shavings out of the intake or are u just trying to break it in
He'll yeah bro
needs an intercooler on an air coooled engine,the turo is as good as an expansion chamber so consider bolting it right up to the exhaust port and run a big exhaust pipe from the turbo
Something caught my eye: the ruber conector where the carb used to sit has an open hole at the top, is it sealed? People here in Brazil put an old spark plug in there with a hose clamp.
DT engine, stator side crank seal usually works it's way out and causes a lean condition. There's no retainer to keep it from happening like on the right side, not sure if that's also a problem or THE problem but I'd imagine the added pressure would make it happen faster.
good at idle but
not enough fuel when turbo builds boost
Boost is built, then throttle is closed under boost. Bypass valve should help drivability; Vacuum operating valve to bleed boost from the charge pipe back to the inlet pipe.
Would u happen to know where I could get a blaster rear caliper ?
draw thru Journal bearing turbos need carbon seal conversion and good consistent oil pressure to function for more than a few minutes. ballbearing turbos work with less oil and might accept oil from injection pump, but youll find it hard to find a small enough ball bearing turbo for a 175cc engine. You felt how hot everything on the turbo gets, the oil system for the turbo needs a cooler as well if the bike is ridden on the road and not just 1/4 mile at a time...
Yes it made boost, I'd go with a different kind of gage for this. Might find 1 more accurate to work with.
It could be over leaning it happens when to put a turbo on a carburetor I put a small injector in the manifold after the carb pushing water and denatured alcohol blue window washer fluid works
I put a turbo on a two stroke pocket bike about 15yrs ago. Git the spool up oil pump even the fairings to fit. Was a laughing. Heavier than the power it provided but went ptshhhhhhh
Let’s go!
Sounds like the crank seal.. that’s why it’s wanting to runaway and struggle to take off.. you’re blowing boost into the bottom end.. the premix from the carb lubes the bottom end.. your essentially pressurizing the bottom end
I wonder what effect putting the turbo before the expansion chamber would have, keep in mind what the term expansion means and what putting the turbo after it would have. Just a thought.
very nice idea but some misinformations about turbos. 1. there is nothing like multiplying air pressure… you can‘t get 4 force out of 1 force. This is not how physics works. I think you meant that the compressor side will rotate faster than the exhaust side. 2. you use a blow off for not hurting your turbo when you have all this not used air pressure, it will escape through the turbine on the intake side, pushing the shaft in the opposite direction of it‘s normal direction. This can wear your turbo much faster but it will be okay for this project. Still it has nothing to do with the existence of reeds in the system.
Its not misinformation its misinterpretation. The compressor wheel cant physically spin faster then the exhaust wheel because theyre attached on a single shaft together spinning in unison. The amount of air being used to spin the exhaust wheel is alot less cfm of air then what is being created by the compressor wheel therefore that would result in a massive increase or a "multiplication" of the air then what is generated by the engines already spent exhaust gases otherwise how would you create a "boosted" situation of air pressure being forced into the engine if it was the same input and output of air. There has to be more air coming out of the compressor side then what the input into the exhaust side is ultimately, this is why i explain it like a multiplication factor because it has a greater output of air flow then the input. As for the blowoff valve i did not say it has anything to do with the existence of reeds i only explained exactly how the bov works and i said for this system that we shouldnt need a bov with how the engine operates with the reeds and i forgot to mention that it shouldnt have any compressor surge because the excess leftover charge pressure just leaks right into the exhaust and the carburetor slide will cutdown the air through the turbo.
Isn't the bypass valve supposed to be hooked to vacuum ? That way when you close the throttle it diverts boost out the exhaust as the engine revs are falling , you don't need boost as the engine is attempting to slow , if you're giving it pressure it might be sending your boost out the exhaust ...
Needs bigger carb bigger exhaust more spark reroute air almost like snorkel and rebuild using dt250 side case with radiator and transmission add bigger front sprocket 38 or 36 rear sprocket use 4mil stroker crankshaft banshee 4in rod trinity 285 bored top end and if your really froggy add 20 shot nos if you don't die a man will be born 😅
So. Having the carb farther upstream than normal and probably not getting as much oil to the internals of your engine are things that might cause some weird characteristics. But with the turbo compressor on that side of the throttle body and no type of blow off you could be building pressure and then causing the turbo to either stall or even spin backwards frow air rushing back through. I think you would have more success if you adapted the carb to blow through, adding a blow off or recuirculator and losing the expansion chamber on the exhaust.
You should boost reference the carburetor but i would do a kiehin pwk air Stryker and you should add a fuel pump for when your on boost so there is enough fuel going to carb when on boose or else you will just suck the float bowl dry in a instant. I believe you can also buy special deep float bowls for the keihin pwk because banshee guys that run pwk's sometimes run them it would hurt. Turboing a 2 stroke is a big learning curve thats you have to go through for sucess everyone who was successful at foung it went through the pain staking process of trial and erorr until they got everything right
Forgot to mention when you boost reference you need to seal the carb real good and you need to boost top and bottom of carb so you don't get whiskey throttle
It started running bad after it started building boost. I'm wondering.
If you don't need to change the reed values. I say that because boost never came back down even when it comes back to idle. It went lean when Turbo started building boost, Raising Exhaust temps.
So bigger jet will help.
Idk how I feel about having the carb before the turbo. Lol what if it gets glowing red? Sending fuel through ot dosent sound like a grate idea idk maybe I'm wrong I found a fuel injection kit from Japan for small engines that you can hook up to a pc and tune
Mike Lake wondered what it would be like to take a two stroke quad and put a turbo on it... and blew a big hole in the case!
several car companies have been looking into 2stroke valved, fuel injected designs that can run a supercharger or turbo. it seems feasible, but maybe the cost isn't worth the gain for them.
