Big Turbo SR 500, the list I bought.

I bought the piping necessary for the turbo with a famous kinokuni which is a piping part.
It became quite expensive.About 45,000 yen.I am worried about the oil’s return is very thin.

Aluminum pipe 60 φ AL6301 2
Aluminum pipe 60 φ 90 ° AL6309 1

And, waste gate.I never remodeled the turbo, so I saw it for the first time.Even this alone is quite heavy.

I bought a hose band with a monotaro.

The CR carburetor is 55φ, but 55φ hose can be mounted properly.

I will install it like this.

Since there is no longer time, if there is missing something, you have to go to Benizen and use generic parts.

Big turbo SR 500, Consideration of turbine mounting position.

I thought about attaching a very large turbine of Kikawa Select to the front of the headlight, but it is very heavy.
It seems that if we do not weld something around the head pipe of the frame it can not tolerate the weight.Besides, its around is quite dangerous as the car body number is close.
Even if it is bolted, the paint will peel off.
To make an exhaust manifold,handling is complicated.
So it seems to be irreversible, so I decided to attach it to the side.

But it is very big.
It seems to be Fury Road.

It is necessary to pass oil to the turbine.(This type of turbine does not require cooling water, so it is OK with oil only.)
The oil line heading towards the SR head,once going outside go through the tube and enter the head.
I am going to branch here and try to turn it to the turbine.It only needs to process the fitting.

I must be careful about how to return the oil.
In the oil seal of the turbine,a labyrinth seal is used.Because rubber seals can not be used as it gets high temperature.
Because this seal method has low sealing property, oil leaks to the exhaust pipe when oil pressure is applied.The oil turned to the turbine must be returned to the engine with no oil pressure by gravity.

I think I will take it from the head oil line.And I think I will return the return to the drain of the oil tank.
Since drain of the oil tank is at the bottom of the oil tank, there is much oil on the top so I think that it is not pressureless, but I will try it here once.If it is not good,It would be a good idea to stand a tap the case and attach a joint.

I made a surge tank with sheet metal and I think that I put it under the seat.↓ Here.

I moved object around and moved it to the operating table.
And I put it on the racing stand.
It is after a long absence that I touch on a motorcycle here.

Let’s get started.
