5 GT Turbo Recomended breather system setup for the GTT

[itzik]

Hi,

There are 2 breather setups for the GTT, stock and "cup" mode, i attached the diagrams for the 2 setups.
In the stock setup the system sucks the gases so the gases are evacueted quickly, i guess it's less likely for oil to escape the cranck case vent in top speed and it less smelly and clean, but the system has more componenets and i am missing some restrictors.
In the "cup" mode it'a a very simple system, but because there is no active gas evaciation it is likley that the "catch can" will be filled up with oil in top speed and it will be more smelly in the engine bay.

Please share your recomended setup for the GTT. What should i use? I am runing 0.9 bar boost on stage 1 t2 turbo.

Thank you

I used your second option to good effect using a catch can with a filter venting to atmosphere.

Did you see oil coming out of the cranck case breather in top speed?

No, probably emptied catch can once every few months. It didn’t breathe very heavy.

Hi everyone, this is my first post, so just wanted to say hello and a huge thank you to all the users here for sharing such valuable knowledge!

I have a question regarding the hose that goes from the rocker to the catch can. Should it go to the top or to the side of the catch can? On the diagram shared by Itzik, it enters from the side, but in another diagram i found, it comes from the top. Does it make a difference? Also, Itzik, would you mind sharing where I can find the diagram you showed?

Thanks a lot in advance!
