How to turbo a carburetor TW200 -10psi VZ21 turbo (blow through)

Blow through carb setup
10psi fuel pump is needed when on boost for a period of time
Quick vid showing how I made the carb work on my Yamaha TW200 farmbike modded. The hardest part is fabricating the pipes to look good. The Turbo is a VZ21 from ebay, alot of the parts are from ebay aswell. EFI vid out now

Stretch the return spring on the carburator slide. The pressure keeps it up giving you the impression that the throttle sticks. Nice work!

[brandonotte]

That’s awesome, see you’re in NZ as well

Hey mate nice build, try fitting a pressure line above the slide, it will balance out the pressure above and below the slide and it shouldn’t jam up. It is really hard to get them to run properly but when you do. 😁👌🏻

It seems the throttle response is not that smooth. Is that a turbo lag? Or just the carb jetting problem?

Kyle, can you make a video how you tune that bike

[beastman.]

Do you have heating problem? IT looks really cool brother.

[yousofal-kassar]

great progect ! .. how many HP did you get after you make this modification ?

[jasperdomacena]

Have you fitted an Efi system yet?

it's running rich when the turbo isn't spooling

putting a smaller jet may make it dangerously lean when the turbo spools up

[bradspeed]

Did it actually produce more power? I'm interested in putting a VZ21 in my 250 cafe racer.. I'd probably go with a draw through setup though. Did you have to pressurize the fuel tank too?

If you don't mind me asking, what was the approximate parts budget including the efi system? Also, have you measured it's acceleration or taken it to a Dyno? Thank you.

We're did you get you're oil feed from and how much oil pressure do you get I've tapped into my oil filter housing on my ag200 but it's only reading 10psi of oil.

[haydenschmidt]

yo bro, looks like you live near me based on the video. Im based in Albany and am working to make a gn250 turbo cafe. would love to chat to you about your setup and show you around the shop sometime. Cheers

what about if you put the carburettor before turbo ? i think the carburettor will work better with vacuum . but i dont know whats about the heat of exhaust and turbo

[harrisdoesthings]

hey man just came across your vid after thinking about turbo-ing my grom, where abouts are you in NZ?

[blaneblackshaw]

How did you fit the bov where does the line go to

[pipegalez]

Hi, I am in the same project! I would like to know What is the reference of the carburetor that are you using for the turbo ?

[TURBO_mania]

Hello. How this turbo work without water cooling?

[maxringwald]

What cooler die you use and how do you connected the Tubes to the turbo and what Pump did you use

[Namesakes.unit-x-sq]

Did you make the charge pipe out of aluminium?

[justinbelshe]

Does it work? I can't tell...

You should probably get it out of town so you can do proper testing...
