Very interesting observation on Works 3" 02 housing

Wangracing,
The dividing wall on the Works housing is a not a feasible project in my opinion. I think you will compromise relibility by trying to weld a dividing wall.
After all I found out that perhaps the hotside on the Evo turbo actually has a dividing wall already..

arent their compressor housings aluminium??

Yes the exhaust housing does have a small dividing wall. But it is very small. I think there would be some benefit in extending it into the o2 housing. From pictures I have seen, the factory 02 housing does have a splitter in it rather than full open mouth.
Yes the WRX/STI from factory did have a flat plate in front of the wastegate and only had a good opening in front of the turbine exit point. But, we did test a full open mouth dump pipe and one with a "splitter" as we called them and there were measureable improvements in spoolup performance of thr turbo with the splitter. ie. The turbos consistently produced more boost at a lower rpm.
Regardless and back on topic, very much looking forward to seeing the 02 housing shootout!!

Call David B. and ask him to pull out his ancient archives.
here is the link to the test that db did 2 years ago. https://www.evolutionm.net/forums/sh...d.php?t=208826
