Turbo return catchtank size

[Truls]

Anyone thats have a idea of size return tank?

I have top bike mechanical pump, 1mm restrictor to turbo, but have problems evacuate oil in higher rpms. 
Currently tank is 55x55x35mm

should i build bigger?

I have a aTD05-16G without restrictor, and the it drainsinto the top of the catch tank. In your case it enters at the bottom with a bend which has some restriction. Tbh it looks like it should work but still it has a little bit more resistance then draining completely free.

Also I dont see a breather?

@peter1127oh that looks very nice

This is one I got of Tomasz Piotrowicz the Polish guy that does the turbo stuff on FB it's only 40x40mm.

Made a new one, almost double cm3. I want it easy assembly/disassemble thats why the AN fitting to turbo.

Can't imagine that bottom fitting is going to have a long life ! ! !  Or the tank come to think of it!

Indeed that doesn't look safe at all

Its just a test to see If the volym is right

Should hold the contents of the turbo and the feed line.

Put a check valve in the feed line. I made my catch tank bigger a couple of times, turned out the oil feed line syphoned the oil out of the sump.

I found i did not need breather.

Biggest issue is the residual pressure when engine off, check valve in feed line works a treat with decent sump. 

I lashed plastic bottle on bottom and watched it tunning and stop and start to work out required volume also found I could reduce my restrictor to .8 but have roller bearing turbo.
