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 🤙

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!

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.

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.
@StupidFastJohn
7 ай бұрын
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.

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.

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.
@StupidFastJohn
7 ай бұрын
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.

You should never run the turbo without the oil system working. You literally damaged the turbo with that short run! Also running the turbo off of the engine factory oil system is a bad idea. For a couple of bucks you could add an external oil reservoir, a feed pump and a scavenge pump. A blow thru set-up, despite what people who don't know anything think, will ultimately be easier to set-up using a boost referenced fuel regulator and electric fuel pump. The regulator will add fuel pressure for every pound of boost and avoid the fuel pissing out all over like every moron that is clueless about turbo fuel systems experiences in almost every YT video you see. You will also avoid all of the tuning issues trying to get around the turbo sucking the bowl dry constantly.

For it to function optimally, I would install the carburetor onto the Turbo air inlet and increase the jet size, so the Turbo is pulling air through the carb instead of it being installed on the pressure side. Otherwise, you might be able to get an injector body and computer off of an old Polaris Indy 500 retrofitted to allow the fuel to be injected into the pressure side. 🤔🤷♂️ good luck. The back pressure comes from the shape of the pipe, not the tiny exhaust outlet that you are attaching to the Turbo. The extreme heat is from running too lean. Get an exhaust gas temperature sensor and tune it to run at 1200° approx 6" away from the exhaust port. Temperatures higher than this will indicate too lean of a fuel/air mixture, temperature lower means too rich of a fuel/air mixture. Hope you can get it to run like a cat whose tail is wrapped with firecrackers. 😂❤

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.

your boost gauge never worked and is junk/leaking but you know that now lol, giver her lots more fuel aswell, start with too much and back down. also cant tell for sure if the carb bowl is running empty or if your lean poisoning the system by overheating it and making it detonate.

I clicked on this for the thumb nail but @ 1:32 I saw you need a hand rail on the stairs behind you. Yeah my spelling sucks but I look at everything.

No need to clean out the metal shavings after tapping the intake for pressure gauge. 25:30 :)

yeah you need more fuel, larger carb or jet, i dont know what that banshee thing was but jetting should be increased with power increases. also you should weld bungs onto the pipe for the gauge and such, threading a pipe isnt going to hold. great try, now succeed =)

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...

Jesus you got no idea what's going on?!? Starving at idle lol. Play with any small two stroke and a diaphragm carb to learn jetting then re visit this piston killer

No way a gravity feed fuel system will keep up with boost. Typically you need to add 1 psi of fuel pressure for each psi of boost. Put the carb in the stock location and add an electric fuel pump with a boost activated regulator.

if you drop a container of liquid, it creates high pressure at the bottom of the container when it hits the ground. Everytime you go over a bump, it's creating high pressure at the float valve. I haven't been running a fuel pump on my 230cc turbo motorcycle. But I do most of my riding on bumpy, city roads. It may be a problem on the highway. But I'm not experiencing boost long enough to empty my bowl. I was running a fuel pump, because everyone told me I needed one. It's been about 3 months without one and I haven't emptied my bowl yet.

Detroit diesels = 2 strokes with turbos
@harrypalmer291

@jarvislarson6864. Yes , a Detroit diesel is a 2-stroke diesel that used turbo charging usually in conjunction with a positive displacement supercharger to efficiently fill the chambers with enough air to make good power . The main difference between 2 stroke gasoline Reed valve type engines found in racing dirtbikes and 3/4 wheel atv's is the diesel used overhead valves that are going to seal against positive boost manifold pressure much better than a Reed valve that flutters open and closed at very high frequency and rely on the piston downward motion to cause a high pressure environment in the crankcase to shut the Reed valve and push air/fuel vapors up thru transfer ports into cylinder. Piston port and rotary valve 2 stroke engines are less prone to manifold pressure causing problems like Reed valves not closing.

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

I'm afraid that you lose all the pressure during the cylinder purge cycle (I hope Google translated it clearly))))
