What do u guys have for experience of T4 housing?
Twinscroll housing,surge problems, spool etc
Turbo range from 6262-6466 precisions
IV got surge problems and are changing to a surge housing now and. 84 twinscroll setup.
Im thinking of changing to a .96 T4 open housing to help the new cover whit surge problems.

 

T4 twinscroll 1.15 or 1.0. Get a gen2 6266 or 6466.

 

IV got a .84 housing now, is That too small? And I have a .96 housing thats ready to go.
Or should i try the new antisurge housing first and see If Thats enough?

 

You def need the anti surge compressor cover. But a .84 twinscroll is def too small.

 

I have a .91 TS T4 on my BW 8875(363SX) with no issues great bottom end and topend power. .96 would be fine.
PTE turbos make power but they don't last that is why I went Borg Warner.

 

I have a 1.05 on my s371 but untuned but I am on a 2.4

 

Around 1.0 - 1.15 is ideal for most of the available turbos to suit that goal

 

do you have any data you can share? I run the S362SXE with 1.00ar on a 2.15L and have considered a larger turbo.

 

We did surge cover on the turbo and il try a few pulls in a week or so and see if it helps much.
Otherwise its a new turbo o bigger housing.
