- 1:Pitot tube is a tube within the charge pipe that acts as a reference to the incoming stream of air, and has an effect of increasing the pressure to the reference. Its an effective method, when using blow-thru carb setup, for improving fueling on boost.
2:Fuel Pump and Fuel Pressure Regulator?
Mallory 4309 and MSD 2225. Total around $180.
you have to have a fuel pump that can feed at LEAST 3 psi over your peak boost number. Otherwise the boost pressure will prevent the fuel from entering the float bowl.
You have to have regulator that has a boost reference, so increases fuel pressure as boost increases, otherwise, the boost will prevent fuel from entering the float bowls.
Awesome vid! Wish I had seen this sooner! I’m trying to setup a very small displacement single cylinder bike with a diy supercharger, and I want to blow thru the carb to get the benefit of the fuel acting as a charge cooler. Thanks for the tips!
I've heard of people plugging the little holes on the emulsion tubes for the pilot jets, i guess this gives better fuel delivery, the float pressuring is critical too, im glad you mentioned that.💯👌
Thanks for the video ! I’m building my own turbo bike using this video 😊😊😊😊
I'm scared to try it haha! looks so confusing.
As clear as mud!
Life's Adventures exctly mannnn!!!! so very damn clear!!! thanks video maker..
I'm glad that my video is being a good help
great vid. used your vid to build my own setup,
One little point I'd like to make note of. Honda carbs are CV style, but they use a special hose in the intake to make the slide lift based in air velocity. Most other manufacturers use a Keihin CV carb where the slide lifts from an opening in the intake side of the carb venturi. No extra hose to consider.
My thoughts exactly... Like a ram air system most carbed bikes utilize
You do cover most the basics pitot tube' regs and pumps at least your trying to explain how it's works good work. I've done a few this way it's never that easy lol
Tubes on the ride are fuel lines for fuel pressure regulator , small tube vacuum tube
Carbs are bolted the plenum then sealed , there is a o ring between the plate of the plenum and the carb then welded the top shut
Ok interesting. I'm thinking to make like a cover on top so I can have access to the carbs if needed.
And about the other thing, I'm talking about the Large metal part (like a large tube) above the fuel pump, welded to the box. It has a small rubber tube in it. What is that ?
yes all carbs for sport bikes have the fittings stock
awsome video. a little nervous it seems but i think its because it was important for you to be correct. thank you. you have helped me alot.....especially with the size of the box. lol, its for my 10yr old sons 197cc single cylinder 4 stroke gokart !
Look for turbo bike on fb and ask for Dave he makes kits for these bikes
Not a problem guys and I'm sure it will work on the dirt bike and if it doesn't have fitting to pressurize it witch I'm sure it does u can use any other carb from a sort bike and fit it
I recommend 86 gsxr1100 carb it's 36 mm carb and works great
Cheers
so did you create a sealed boost box around the carburetor?
Yes it did if u dont have it just drill the top of the ball ans weld it or glue it on
Cool thanks for video bro 👍
Well done.
What happens with the vacuum tubes of the carbs? Where do we conect or it stays the same?
He said everything on the carb stays the same
@vespa400car nope just straight through because if u block them the carb won't provide fuel under vac
Does he even know what he's goin on about.. 😂
😂
basically I've got no idea what your talking about
nice vids good info what type or brand of fpr do you run? id like to get one
How do you build the pitot tube? Is just a tube that pass from one side to the other on the big tube and with a hole on the center? Could you explain me more about the pitot tube? Thanks
What do you do for timing?
Thanks and what u mean with fpr
1 black then paint dark silver on top and stripe it with a think stick before it dries
That's the turbo up pipe , feeds air from turbo to the air box forcing the air threw the carbs
wait...The turbo pipe isn't the one on the left of the bike ? The one that goes under the bike ? I'm talking about the other side, the one just above the fuel pump. For example you can see it at 04:15. Thanks
and what about the pipes that comes from the carburetors ? The ones that controlls the springs. Normally they go in the air box in some small cases. How did you attached those?
02 is efi so it's much less complicated and u don't need any any of the fuel stuff unless ur looking for high hp
Dear sir, I'm very interested to get more information from you for turbocharged a carburetor motorcycle, wish you can email your contact to me to topsecretjpn@ymail.com. Thank you.
This is a GREAT VIDEO! Can you do this with a v twin 2008 hyosung gt640
Hey Sayfdyn, just wondering what exactly is the paint finish on the bike. It's what I've been looking for. Thanks.
Im looking to turbo a suzuki gs 450. So all i need to do is go up in jets put an oil pump to the turbo make a metal air box and attach pressure lines to the slides and the bowls and then the box to the carbs? is there anything else?
tell me the outlet of the fuel pressure regulator plug directly to fuel line? the pressure was enough to push the folt valve?
i have a mikuni flat slide vm33 carb where the slides are operated by a linkage instead of vacuum or whatever. so .......important trying to say how does that work with a turbo?
This tube, that tube, your tube, my tube, didn't know tubes did all the work!?
Nice bro
so how does in not spit fuel out of the vent in the carbs
Question i have a 98cbr900rr i dont have a fuel pump its vacum fed trugh my pepcok and a diaphram on the pepcok and a vacum hose commig from the 3 cylinder to the pepcok do i need to install a fuel pump or a larger what APE calles their guzzler pepcok that works off two vacum prorts to flow fuel faster?
Rage Cage07 you need to remove the vacuum ports so fuel flows under boost... if u put a fuel pump with a return style fuel pressure regulator you will need a return line fitting put into your tank higher than fuel level or it will restrict the return line and give u sky high fuel pressure and flood out the bike
@Ryan h I think stock are cv
i dont get a thing :( i hope you make another video with diagram or any drawing. good video tho.
mate need ur help turbocharging my royal enfield single cyclinder 35occ with a carb
the capacity is small. cant have a turbocharger on it. also it needs a intercooling system. which an Enfield doesnt have. as the compressed air is really hot and it may cause knocking.
Melwin Daniel Nadar you can use water/meth injection and no intercooler because the water being injected cools air temps in the combustion chamber and the meth is super flammable and will raise octane levels to suppress knock
awesome and can you suggest a carburetor for it
The part above the pump is the blow off valve it's the part the makes pusshhh sound , and these pipes u just conect directly to the plenum exactly like in the the video
oh...The blow off valve ! that makes sense. thank you !
i have a 3 cylinder 1000cc... how big of a plenum? I might have to make one...
A lot of good info although your video needs a little more light to be able to see all parts clearly
I want to do ram air intake so all i have to do is conect the float bowls tubing and the vacuum tubes from the carbs can i conect them on the air box so they can be at the same pressure as the air box i forgot to conect those tubes and at litle more speed its sputtering and loses power
The Rider hello,, bro did it work the blow truu carb stuff using the same method as the vids is showing???
I am doing the same thing to a 250 v-twin, I kept the original air box and added a 3 phase BLDC motor with an ESC controlled by the carby's Throttle Position Sensor, you need the carby's air vent/vacuum hoses to connect inline with a Pitot tube to balance float bowl pressure under higher boost. If running higher boost than 5psi you will need an electric fuel pump and regulator otherwise it will run out of fuel at high boost and prob detonate your engine which will melt your pistons, not connecting carby vacuum tubes will have the same result.
amigo tengo mi moto 220cc le puse un turbo pero a lo q le empiesa a meter aire al carburador se me apaga como hago para presurizar el carburador
So for example I'm putting a turbo on a 250cc 4 cylinder bike;
Ill need a 400ml minimum sized plenum (Replace Air Box), to pressurise the carburettor bowl, with pressure from the plenum. Ill need a fuel pressure regulator with a boost refference and a high pressure fuel pump, with the regulator hooked up to the carburettor vacuum(now boost) line.
Now with this done ill need to re-jet it? and will obviously need really good float needles... What I didn't understand is what you did with the diaphragm breather? Did you just hook that up to the plenum too, that would make sense to me. Also you put a non-return valve on the line going to the bowl, so that under vacuum it doesn't suck fuel back into the plenum right?
Lynxdragon put the biggest air box u can fit it will make tunning the bike simpler because it will make the boost more stable. you need a efi fuel pump with a boost reference fuel pressure regulator (fmu) you want about 3 psi higher than boost psi (10psi of boost is 13psi of fuel pressure) to help fuel flow or if boost will force the fuel back into your tank. also its a return style so you need to add a return fitting into your tank above the height of fuel level or you will restrict the return and never get a steady fuel pressure.. the line from the air box must go to the fuel bowl vent (same as ram air) to help force fuel in... this is the only way to keep about stock size jets so it will run good on and off boost. and no check valve float bowls vent tube as they are normally under vacuum and will ballance out themselves
Great info. Why don't you have any youtube video's? You a member of any forums or fb pages?
how well does the engine temp do with just 1 radiator?
U don't always need intercooler.
Intercooler is definitely better and denser the air charge but it's not a must
I own cbr1100xx turbo with no intercooler to save wieght and I run 30 psi with no cooler on alcohol
I got a far 600 1989 i want to boost it . How do i do it
hello, nice vid, I was just looking for some clarification as to where the first tube from the plenum (mentioned around 55 secs in the video) attaches to on the carb in order to pressurize the slide? Are you talking about a vacuum port or...? I understand how to pressurize the float bowls though.
thats only boost
straight to the plenum
ohh sorry i didnt read!
and thats for the carb slids the thing on the top and has a needle
and the tube coming out vents it
sayfdyn1
ok thank you for the quick response. I might ask you to look at a pic of my carbs in the future if I actually proceed to turbo one of my bikes.
can i turbo my hornet 600 2002
with out any danger on my engine
if u do it right it should be ok ,make sure your engine can handle the amount of boost your running
What are u looking to know ? Ask and I could reply as that could help others who have the same question
What is the "tube" attached to the air box in the right ? and how did you attached the box to the carburetors because it seems welded all around ? thanks
Do you use a one-way valve on the tube that goes from the pitot tube to the float bowl to keep it from sucking fuel out when the engine is under vacuum?
vespa400car no because cv carbs are made to be under vacuum so fuel flows under boost the floats need to see a higher pressure to force fuel into the carbs.. as this will also force fuel into the motor... also a big reason why the main jets can stay stock size make sure u use a efi inline fuel pump like in the video but he for gets to tell you to use an fmu you want 3 psi higher that boost psi so fuel will flow and you dont need huge main jets this way idle and out of boost runs well
3 psi high fuel pressure than boost... so 8 psi of boost is 11 psi fuel pressure
i have a 02 Suzuki bandit 600s im trying to bost it where can i find what i need? is there a website
i want to turbo a car with a carb. did your carb already have a connection the pressurize the bowl?
people just google how to turbo a motorcycle... once you read you'll understand everything he is talking about but a pilot tube in the intercooler piping works better to put pressure to the float bowl rather than tapping into the air box as you wouldn't see the correct volume.. the sizing of the air box gets larger with less cylinders (smaller cc) as the exhaust pulse is so far apart you need more volume in the air box to keep pressure steady..... i can go on and on but you can find articles from people who know more just look
So have you blown that motor yet?
Hi, do you have a diagram somewhere?
WHAT KINDA CARBS ARE ON YOUR VTR1000?
if two cylinder cbr500r also can install turbo/
Does it work on a R1 2002 too?
do you even know how to make a video? or how turbo really works in carb bike?The way you are explaining can't understand
Do you have a wideband? So does plenum size dictate how well it works?
i do have a wide band ,im not sure what u mean with how well it works .
the plenum size helps with tuning and air flow etc
Any experience with using a blow through on a Harley?
I'm getting ready to try it on my sportster.
All the info I've found leads to completely sealing the carb and the plenum outside but connected to the carb. The carb has to be modified where it can be pressurized. How are you figuring what size your plenum needs to be? I've heard several different ways. Thanks
Fuel pomp psi?
Can i try this
to my yamaha mio soul efi?
bibo Bisa..
I MEAN WHAT KIND LIKE CVK OR WHAT ?
I have also turboed a bike
Mine is a motovert with a 150 cc
Look up Tomoz 150cc turbo
pressurizes what ?? sounds like you said light ???
Fz250 can have this turbo help me let me know
came here for help but nvm
do i have to do that if i put an electric turbo with Just 3 psi?
An electric turbo wont work so no. Your better off just getting a regulator and running pressurized fuel to it. It will make your bike alot faster just from the extra fuel pressure.
@GOTBOOSTNINJA stock carbs
120psi fuel pump?
You mean 120lpm fuel pump
AllAroundAuto I'm pretty sure he meant it's capable of 120 PSI... he explained that he runs 3 PSI at idle and it goes up on a 1 to 1 ratio with Boost.
But he said 3psi over PEAK boost number, I'm confused lol
@@ridintilldeath9484 He means you need a more powerful pump than the boost from your turbo because the boost pressure will push the fuel back out of the carby up the fuel line into the tank, most pumps are capable of doing 50-100psi or 300lph which is way more than your average turbo and then you will just spray fuel out of your carb and flood it, so then you need a fuel pressure regulator which is adjustable so you can lower the fuel pressure back down to be the same as standard boost psi + 2-3psi as 2-3 psi is standard fuel pressure but it needs to be higher than base level boost pressure, so say you are running a 10psi of boost so you need to set the regulator to 13psi. The regulator has an inlet that allows you to run a line from the turbo to the regulator so as you accelerate and the boost builds up it increases the fuel pressure from the regulator to the carby at a 1:1 ratio of boost to fuel. So that way you will always have a constant equal supply of fuel to your carb. Otherwise as the boost builds up the fuel wouldnt be equal and you will most likely stall at higher revs.
so are the carbs in that box
they are attached to the box ,right under.......
What does he mean pressurise the slide
gareth liddle if u take the air box out you can see the slides and those slides control the height of the needle
Pressurizing the slides means or what I meant was to connect the vent of the slides diaphragm to a pressure source aka the air box and that will allow the needle to lift under pressure there for you will have more fuel to the motor.
You are talking about cv carbs then
Man I have a problem with a proyect Im building I am trying to put a supercharger on a volkswagen rabbit 84 I install 4 carburators of a kawasaki 900 cc and then I try to make a blow through carburated sistem but when I start up the engine on idle the engine runs good but when you acelerate the engine starts to fail and it shuts down.
I have the original mechanical fuel pump you think that could be the problem?
I hope you could help me thanks
paloysamu luna moran Maybe I'm wrong but is the fuel pressurised as well? If I'm not mistaken if you're running boost and haven't pressurised the fuel as well the air will push the floats close and there won't be any fuel getting mixed. Does make sense to you?
In idle you're not getting any boost but when you accelerate you create boost thus closing the fuel feed. Think about it.
Spot on! not enough fuel = lean A/F ratio = kaboom
I need help turbo my Kawasaki zzr 600'can we get in contact ?
hey bro wanting to turbo a 125 trail bike for fun haha but quite a newbie to this kinda thing any chance you could flick me some instructions/info/ideas that might help
thanks
cam
Very cool invention, but wouldn't you need more fuel not only to the carbs from the tank, but to the heads from the carbs? I have a little experience with carbs on bikes, And I know when you give more air it needs more fuel. Maybe the fuel pump is pushing enough fuel thru your stock jets. But don't you think you need to rejet the carbs for it to run properly?
the gas is sucked by the air flow. bigger air flow provide more gas. but i would rejet the carb.
Wouldn't the air pressure push the floats close and thus blocking any gas from being mixed?
I don't think so, the float is closed by the fuel level.. if the bowl is pressurized the float is just simply under pressure.. pressure is not directly pushing the float closed - also the fuel pressure is to be set at 3 psi above boost pressure so fuel will enter the bowl when the bowl is pressurized. That's the reason for the boost reference fuel pressure regulator, that regulator will maintain proper fuel pressure in reference to boost pressure.
Uhhhh hmmmm pitot tube should Answer your question to why you don't need bigger jets vadim khrustaley
@@ridintilldeath9484 anytime you add boost you have to add fuel to maintain air/fuel ratio. That's done by either drilling your jets, or by putting bigger jets in.
you have no idea.. cat got yout toungue?
are you a member on vtr1000.org the firestorm site?
will you join up and talk us through how to do it please
2 cylinder 1000cc setup? Anyone have this done before? I need help lol
996cc honda superhawk
so hard car are easy to turbo
what's 9+10 ?

This video is very confusing. Did you mean engine PULSES when you said "plus"? And it sounded like you meant 30% PSI over the boost you want to run, not just 3 psi, because your math did not add up at all. I think it would take much longer than 10 minutes to properly educate people on how to turbocharge a carbureted motorcycle. You also stated that you keave the carbs internals alone. That just cant be true. You would have to change out the jets, adjust needles and everything else involved with tuning a carburetor. What do you mean by the plenum or "pressurizing airbox" pressurizing the slides? Does the air somehow push the slides for the carburetor? Thats what it sounds like from your video but that cant be right. If thats the case, how do the push and pull throttle cables work with that? To me it seemed like it would really help if you knew what all the parts were called un the video and explained what each component does. You tried to explain in detail what a couple rubber hoses did, but didnt explain to anyone what the fuel pressure regulator or other major components do. I think this video will confuse people more than anything or possibly make people think its super easy by the way you generalized motorcycles and their engines and vastly dofferent technology and characteristics. Did you turbo charge this motorcycle yourself or did you pay a shop to do the entire thing and just recorded yourself trying to explain it afterward?
I don't know the level of your experience. I do know a lot of these people commenting will be thinking it's a easy job.
I've been researching on this for 8 months. Sooner or later I will have one on my Harley sportster. Before someone attempts it they have to understand what,why and how it all works. Some of the things I've come across blow my mind. I have had to learn things and understand things I didn't know anything about. I had to learn how to seal my carb and pressurize the float bowl. It's crazy what all you have to learn.
Actually, I learned what I can’t here for. The pilot tube to pressurize the bowls and how to install it. Thanks for the video. It helped.
does it work on a xr100 (Dirt bike)?
lol that would be so funny. But yes, I guess anything is possible.
43shadows doing it currently to a 110 on a 50cc super pocket bike frame! t3/t4 turbo lol
superfunnyman123 Me too! working on my 100cc honda bravo mc
ok
hey sayf edyn
ala naman naging prublema un nalagyan mo ng turbo yan lately?
Thats a dumb question, since the guy is obviously not speaking tagalog
hello sayfdyn1. Great work. I'm really impressed about your work. I also have a 1000 vtr firestorm and I want to install a turbo as well. There are some things I don't understand in your video. Could you help me with some info? I would really much appreciate. An email would be great or some contact info. Cheers !
Why does everyone do (how to videos) without showing how to, just showing the results.. people are stupid I swear...!
Yeah he's stupid. Look and see how many successful blow through set ups there are on small carbs. I'll give you a hint... no many.... but the dick in the comment section on YT calls this man stupid. Love the internet.
Its a blow through, Hes blowing through explaining fast..🤦
holy shit this is so wrong. This has to be fake.
what is wrong about it? I'm looking for proper guidance and would appreciate your input!
He's just a troll who needs to do more research before he comments something negitive on someone else's video.
Or just buy q motorcycle carbs a re jet it
Wth
can't understand a f****** thing you're talking about

Wait....what? You have no idea what you are talking about.
can you explain properly? I'm looking for proper guidance on my turbo 400cc single cylinder carbureted project.. its not a CV carb..
basically I've got no idea what your talking about
