You really do remind me of my dad .... An amazing man ... He always kept us kid's interested and excited and inspired.. like you said they sure are fun to work on!!! I cannot wait either to see the engine in the engine bay... And to hear it with the exhaust.. I'm sure I could hear the turbo spooling up!!!! It was definitely and with the exhaust we will hear that beautiful sound allot like the real thing.... Nice work!!!! I'll be watching and listening and injoying every second mate😲. GOD bless you and your loved ones Dennis.. lots of love from new Zealand..
That’s so cool 😎 your a genius I love when like minded people get together and give each other ideas to bounce off each other I like to call it building
I watch 2 people only on CZcams. Dennis Dempsey & JohnnyQ90. Shut up, Tune In & Dream... :) Got a Toyan L400 and I love watching you go bananas on yours! Given me so many ideas.! Thank you so much for your ideas and videos Dennis! Only way someone can dream!!!
I'd leave it just as it is... putting compounds and a CAC will probably cause a drop in boost(if it is making any), where this current setup seems like its pretty stable....I would recommend lapping the valves like Johnny did on his though,so you'll get a full burn..just by doing that,he had some incredible gains in rpms...great video!Liked and SUB'd👍
I saw the keychain people made a genuine prototype supercharger with a ges- 1 turbo with a changed impeller driven by a belt , it made 2.5 CFM , you could modify the tk10-r and drive it with a belt , seems like they work okay .
JohnnyQ90 made a simple setup to check for the power of the engine in one of his turbo video. You should try to make one and check for performance gain or loss. :D
Easy I bought a cheap wind chime and used the pipe, the manifold is a piece of steel tubing, I welded up the ends and added 2 out pipes for the turbos.
Awesome!! Intercooler would be awesome. But I do think a compound setup would give you the most boost. And have you thought about using a check valve possibly for a blowoff valve? I'm sure you could somehow modify one to work.
@@mwestie12 as a professional auto tech of 25 years and as someone who has worked on many real-world, turbocharged drag cars, I actually kinda DO know... Not trying to poke fun, or wave my pecker around... I just know from experience that a turbocharger is a pretty precise piece of equipment (many spin over 200,000rpm when you're flooring it) and also the shape/sizes of the wheels/housings is important. That little thing is just a keychain toy for fun. Looks cool, but if anything, it's taking power away from the engine by choking it's exhaust and intake flow.
@@billymanilli yeah your not the only one who has real world experience! I've also been an automotive/heavy equipment mechanic since 2004. I've also been building nitro rc cars since I was in Jr high. I've built multiple supercharged rc engines before that have produced significant power increases. So like I said you never know if something like this would actually produce anything significant amount of boost. And I believe that the best way would be to build a compound setup. There are a couple of people on CZcams who have successfully created boost with these engines.
*blow off valve is what you're lookin for (that pssshhhh sound when you let off the throttle)... The wastegate is a different component all-together that controls the boost pressure by opening to let the exhaust gases bypass the turbine wheel (in a nutshell).
@@billymanilli yes you're right. My bad. I don't know much about turbos but I do love that sound. About 20 years ago I tried racing another kid I had a fireturd with 305 5 speed, totally stock to. he had a fucking neon with a big fart can exhaust. Well he spanked me. I was prob 5 car lengths ahead and I heard that psssht coming up behind me. hell of a sound.
@@BobSmith1980. That's cool man. Believe it or not, my very FIRST car was an '84 T/A! Mine had the 305 H.O. w/ a 5 speed. The 305 that year made 150hp, and the "High Output" put down a whopping 190hp.... in a 3600lb car! lol Yeah they were definitely not very impressive... I put a 350hp/327 corvette cam in that motor, a performer intake and gutted the cat, and it woke it up pretty significantly. Could at least beat the stock mustang gt's with it then! lol
Alright, here is my $0.02 on this turbo project: You will need a better system than a keychain turbo. They are simply not made to work as a turbo at all. They are toys that simulate a turbine, but they will not improve the performance of the engine. They will actually decrease it. If you want a system that works on these engines, you need the following: *SUPERCHARGER instead of TURBO: As you know, nitro engines run oil-mixed fuel and that highly decreases the turbo performance, but not only that, the oil in the turbine will make its way to the compressor and back into the intake manifold creating an out-of-whack mixture rate. Needless to mention the oil will quiet down the whistle turbos make. Buy or create a supercharger. Make sure the oil is only inside the sealed bearings it uses. That will give you a cleaner setup to start with. Once you have the system created, and no vacuum leaks are present. Then you need to think about a better forced fuel injection system.... carburetors are fine, but you need a fuel pump to put more fuel into the chamber. Otherwise the fuel-to-air ratio will be off and the engine will either run very unstable or not run at all. For testing purposes, you can connect a fertilizing hand pump to the gas tank and use it to increate the pressure in the tank.. After all of that is sorted out, then the rest is all about fine tuning the details. Obviously in these engines you don't have an ECU and/or sensors telling you all the details happening inside the engine so you will have to guess a little bit here and there until the engine seem to be running fine. Good luck and thank you for these videos.!
Pablo, man I was just saying pretty much the same thing as you, the other day (minus the supercharger part)... But, now I feel a little silly, and wish I had watched this video first (that Dennis posted) czcams.com/video/zhlbmW2wsEU/video.html Turns out, these things actually ARE made to be real turbochargers! All precision machined wheels and housings, ceramic bearings, etc... They even come with a spec sheet with a compressor map on them!! This one's got me really curious now, after seeing that..
@@billymanilli Yes Bill, but with nitro engines there is no way to get rid of the excess oil that comes already mixed in the fuel. It will not produce the desired speed and air pressure + it will rich/flood the engine with oil from the exhaust. Supercharger is the way to go... even converting this keychain turbo into a supercharger. But definitely, its not good to power from the exhaust of a nitro engine.
@@P_double_H Just curious, how the oil from the exhaust will get into the intake charge?... It says on the sheet it has a sealed center section, with ceramic bearings. Only issue I kinda see, is the turbine and housing will get "coked up" from the oil eventually and maybe need some cleaning... 1:1 diesel engines do very well with turbos, and diesel fuel basically is oil... You can really see it pouring out of the exhaust on a lot of "souped up" diesel trucks. "Rollin' coal", is the term they like to use for it, I believe... lol I do agree the oil will cool the exhaust some, which will reduce the efficiency... but I don't think it's not worth doing still (providing the turbos actually are as advertised, and are about the right size for this engine). Either way... can't wait to see. Go Double D!!
@@billymanilli Bill, if the turbos were sealed as you mention they are supposed to be then it would fix the issue with the fuel mixture. But take a look in this video there is a moment when Dennis gives it some gas and you can clearly see oil particles flying from the turbo. I don't think these keychain turboes actually seal the compressor and the turbine sections of the turbocharger. It would be great if it would be sealed as you mention its advertised as. Despite the little nuances I see in the build, its great that he is doing it. I am not saying itsva waste of time. Everything RC is time well spent!
Hello brother. I follow you for long time and plan to build my own one. I heard that L400 have a problem about crankshaft broken maybe because no jounal brearing. Do you got this problems too? I dont know if Toyan would fix this problem or not.
Hi brother, Thanks for supporting my channel, the toyan L400 had a crankshaft problem on their early production engines. they do replace the crankshafts if you have this problem, sterlingkit sent me a new crank at no cost when mine broke. youtuber Timsane is making the center bearing for these engines and some other upgrades also. from what I read the L400 engines made after march 21 2021 have the upgraded crankshafts in them.
@@dennisdempseyradiooutofcontrol Thank you bro. That's a good new. I just worry about they send a new part take very very very long time of shipping hahaha. Did you try to fix a clutch slipping? I tried myself to put some cheap and easy to find materials in the surface of the stock clutch shoes. One thing that I tried and work very well is gasket paper 0.7 mm. I cut and stick with locktite on clutch shoes surface (Scratch the aluminium surface before stick it). It make less gap between the shoes and the bell which can grip at lower RPM and almost 100% of surface touch the bell, more grip when it hotter after run for a while and very last long than aluminium shoes. Maybe find some better materials than this gasket paper.
@@TheArbung That's a great idea on the clutch bro! I have been trying different clutch's and I see sterling kit offers a 3 aluminum shoe clutch now, I just got one in the snail mail today lol! I am trying the bigger Baja 5 clutches right now but with the extra weight I'm afraid to break another crank lol.
You really do remind me of my dad .... An amazing man ... He always kept us kid's interested and excited and inspired.. like you said they sure are fun to work on!!!

Thanks my friend! yeah its loud and needs some love with the tuning lol,
Twin turbo L400 in the felony!
Funny you mentioned that because it crossed my mind lol!!
Twins will work 👍👍👍
I think so too!
Awesome stuff man, new to your vids and enjoy the hell outa them!
Welcome aboard! and Thanks for supporting my channel my friend!
Haha brilliant 😁, I guess you can’t go wrong with 2.. that anodized finish looks great with the rocker cover
Thanks 👍 yeah I wanted to color coordinate everything even if they didn't produce boost.
LOVE that whistle,2 gonna sound good
Yeah it almost sounds like a supercharger lol
That’s so cool 😎 your a genius I love when like minded people get together and give each other ideas to bounce off each other I like to call it building
Thanks my friend!
So cool! Awesome video
Thanks my friend!
Funny at 2:11 looks like you waved a magic wand to it for luck. 😂 Nice 🇨🇱👍
LOL!! I just noticed that! lol
Woooo, nice man!🤩👌🏾
Thanks my friend!!
Great job 👍 . So bad ass 🔥 .
And everyone thought I had no brain cells left lol!!
The best 👍Thank you
Thanks my friend!
Yeah man I love it my favorite CZcams by far
Thanks my friend!
Magnificent !!!👌👌💥💥👍👍
Thanks my friend! I had to try it lol!
I watch 2 people only on CZcams. Dennis Dempsey & JohnnyQ90. Shut up, Tune In & Dream... :)

Thanks my friend! I installed a second turbo not compounding them and it is better with 2 on it, I will post a video this week.
Totally awesome den would love to build one just a little out my budget 👍👍👍
Thanks brother! maybe down the road you will have a chance to build something.
I saw the keychain people made a genuine prototype supercharger with a ges- 1 turbo with a changed impeller driven by a belt , it made 2.5 CFM , you could modify the tk10-r and drive it with a belt , seems like they work okay .
I would also recommend lapping the valves, makes a huge difference on these little motors
Yeah that does make a huge difference, I seen JohnnyQ90's video on that.
Sweet!
Thanks brother! 👍
I need this
Need to see if you can hold the clutch Bell on it load the motor up and see if you can get it to build boost that does sound awesome excellent work
That's the plan, I am going to add the second turbo first.
@@dennisdempseyradiooutofcontrol patiently waiting no rush lol
Sounds better with one compared to two.
Nice!! Do you have a tachometer to measure the rpm?
Yeah but its lost in my nightmare build room somewhere lol.
JohnnyQ90 made a simple setup to check for the power of the engine in one of his turbo video. You should try to make one and check for performance gain or loss. :D
I seen his video on that and was thinking the same thing.
That’s awesome!! Do you think it’s making boost?
Not sure I will have to stuff it in something to check, If no boost it still looks cool lol!
I highly doubt in the performance of this setup but the sound is cool!
@@dennisdempseyradiooutofcontrol yeah boost or not, it does look amazing!
Yeah i doubt it's making any boost cause it's a keychain. But it does make it look really cool!!!
Ya buddy!
Adding the second turbo next video!
Way cool
Thanks my friend!
where do you get the turbos ? just need a link
Ok thast loks cool and all but is it actually producing any positive pressure?
I really didnt get a chance to check it before the crankshaft broke in half lol.
Fantastic video! i really wanna know how you made the pipe for the turbos.
Easy I bought a cheap wind chime and used the pipe, the manifold is a piece of steel tubing, I welded up the ends and added 2 out pipes for the turbos.
@@dennisdempseyradiooutofcontrol nice, did you make the pipes for the turbos or did you buy them? Sorry for asking so many questions.
@@07frbaiz No problem with the questions, I made them and used rubber hose to connect them.
Awesome!! Intercooler would be awesome. But I do think a compound setup would give you the most boost. And have you thought about using a check valve possibly for a blowoff valve? I'm sure you could somehow modify one to work.
lol... that keychain turbo isnt gonna make any boost!

HELLO DENNIS. I AM VERY INTERESTED IN AQUIRING ONE OF YOUR MASTERPIECES.
Thanks for your interest, I'm figuring out what direction to go in, selling some of mine or do builds to sell,
The twins would be dope but your running hella rich rn
its the first fire on this engine so I richened it up not knowing what the turbo was going to do,
This is cool I'd like to see a pressure gauge and see if it's actually creating any boost!
I want to do a video with a boost gage but I broke the crankshaft in two, now I'm waiting for another one to be shipped to me.
@@dennisdempseyradiooutofcontrol it dosnt boost, trut me. another tuber home built his own centrifugel supercharger, it just dosnt have the revs
What Turbo do you use dual bearing single etc. or what
Yes I custom ordered them with dual ceramic bearings and a CNC machined billet impeller
You need an exhaust to make some back pressure, really get some power out of the turbos
Super awesome work dude!!!!!!
Thanks brother! wanted to experiment to see if they worked lol!
where do you get a turbo this small :D
www.keychainturbos.com
what is the turbo is it from a keychain?
Yeah, they have been upgraded with a cnc impeller and ceramic bearings.
2 TURBOS!
Next video will be the Bi Turbo 👍
Where you get the turbos
You can custom build the turbos at keychainturbos.com.com
Where did you buy those turbos again?
www.turbokeychains.com/
@@dennisdempseyradiooutofcontrol Thnak you
let it spool up for a couple secs so we can really hear it!
I will as soon as I get another crankshaft, this one broke in half lol!
A waste gate would really sound unbelievable if you could make one too
That would be cool to add one even for looks
@@dennisdempseyradiooutofcontrol that's true too

Your going to need a bigger tank if your going to put another turbo on it. Lol

Sounds awful no boost
