one WG on divided manifold ?
one WG on divided manifold ?
hi guys, i'm new here;
i serched but not found straight answer - i'm doing custom divided manifold for gt35r wit t4 divided housing and i want to do only one WG with 2 separate pipes (1st form 1&4 cylinder and 2nd from 2&3) going straight into one WG (44 or 46mm) - will it work without boost creap ?

Dual gates would be better. Duals will give you better turbo spooup. As you can set the initial gate to open later since there will be a second gate to back it up.
Duh. For example .. Let's say that your target boost level is 27#: With two staged gates you could set the first gate really tight to 25# and the second gate to open at 27#. Otherwise if you only had a single gate then you would have to calibrate it looser and your turbo spoolup would suffer.
Of course, you probably have a different point of view. But that is OK. Needless to say, with dual gates you can run the 1st gate tighter since the 2nd gate backs it up. So, you will achieve faster turbo spoolup.

both my W/G's have 22 or 24 ''i forget'' PSI springs in them. i would like a minimum of 28 but i do not think they make springs that stiff.
