Tiny single cylinders like this need an air capacitor to make good boost across revs. See the SAE article "A Method for Turbocharging Single-Cylinder, Four-Stroke Engines".

Yes totally a plenum is required, IIRC about 4 times the capacity of the engine for a single, 2x for a twin

[@xferth]

When Boosted boiz was turboing his shopping go cart with a singleCYL he was encountering same problems lol. its not as easy as slapping a turbo on and putting oil to it. but yeah he ended up doing an air capacitor, and restricting the oil so no overflowing. Sadly he ended up putting it on efi and a fuel tech to make it even work well. i know tons of people have made carbs work. he was just a car guy a knew that doing efi would fix it all. but thats expensive haha

[@colinsmith7355]

Hey Dudes,, Try a T-piece between the oil pump and the turbo,, feed it back to oil tank, that way oil gets to turbo and excess oil Tees back to tank when oil pressure into turbo is maxed. We used a boat fuel pump on our YZ125 shifter kart with similar principal for fueling. Also diaphragms were being destroyed in pump, so a 8mm hole in vacuum pipe helped save diaphragms by dropping its sucking pressure..

[@Beardest_Fishing]

Plenum volume doesn’t make a hill of beans in a forced induction engine. The rubber pipe was sucking in because the engine was requesting more than the turbo could give. Shortening the plenum volume and hot side only helped you. You need a much bigger turbo. That little thing is giving all it has and the engine is still wheezing. You can clearly tell when the boost gauge never goes to any positive vacuum meaning there is no positive pressure in the plenum even though it’s small enough a turbo the correct size would blow the intake valve open if you disabled the waste gate like you did on the current turbo.

[@gunsthug1396]

[@Bobpeter100]

"I've just spent my entire life trying to figure out how things work." Yes dude! Thats it!

[@stevebryson3702]

Intake pipe sucking closed is a function of the air velocity and restriction at the pipe inlet (the turbo). It oscillates as the intake valve opens, air rushes in, lowering the pressure in the pipe, then the turbo refills the pipe with air as the previous air charge exits the engine. Repeat for each cycle.

Can i just point out that the oil reservoir is insulated? So the oil is going to only cool off either very slowly or its going to only cool off while going through the pipes.... i mean i guess you do have a lot of oil and that is what a reservoir is for also you definitely need a larger radiator.

[@rhyslane9713]

The oiling issue is because the drain isnt flowing enough by circulating it back to the head it doesnt let the turbo drain properly because all the oil ports in the motor are tiny so you create pressure that blows past the seals I had same issue and resolved it by having the drain line as big as possible and as free flow as possible, think of a turbo car and where the turbo drain goes which is usually straight back to the sump with a way bigger line then your feed line.

The carburetor is too small even for the stock engine, you are restricting the turbo and thats why its not making boost. Try a 24-28mm carb. Also the oilreturn should be lower than the turbo and really free flowing, even with oil from the engines pump it may still need a 1.5mm restrictor

[@willsullivan6195]

First off on the turbo you need a oil restrictor the spot where the turbines are is your Inlet that is where the fans pull in air from so you cannot have a pipe attached to the front of that anything that comes off the side of the snail is the boost reference or the boost pressure so if you're doing a pull through carburetor your carburetor would have to have an inlet the same size as your turbo

Just an FYI, it burns oil because the Carb is pulling a vacuum on the compressor side of the oil seal that wasn't designed for vacuum. They sell replacement seals that are designed for draw-thru setups for this exact reason.

[@villekinnunen6357]

You need a very short exhaust manifold to the turbo and a very tightly sealed waste gate if you want any boost. A short charge pipe isn't a bad idea either, it probably helps the mixture.. 😁
