GT50 turbine flows about same as Holsets 97/92 which is much more than any S400 turbine, except Joses new aftermarket turbine for S400.Would be better to compare GT50 housings as GT47 comperes with 92mm BW turbine.
While it would be nice to know what all manufacturer specific housings there are for the GT50 I doubt that anyone has a compilation of all those numbers.
Since the newer BW housings have CM identifiers on them I think it is the 1.58 that lines up with a 36cm, so 40 would be similar to a 1.65.

Matchbot says 96 turbine with 1.65 housing flows about 54 lb/min. I have been told that GT50 with small 1.08 housing flows 58 lb/min.I have flow values for the S400 turbine converted from Phi to lb/min supplied by Borg Warner, you may be surprised what the S400 turbine is capable of.
How do you go about calculating an engines exhaust flow?
All I could find was in a Donaldson catalog.

I have gated 1.41 from Detroit Diesel. Volvo 1.24 GT47 housing was machined in place of it, because Volvo and Scania housings are smaller like HX60 housings.Aren’t those aftermarket GT50 housings single entry?
Would have to look to OEM to get an actual comparable divided housing, I’m almost certain there is a 1.41 internally gated cat specific housing, probably some that are even larger beyond that as well.
Could it be possible that Holset housings have also A/R number, or do those numbers just happen to match sometimes ?Since the newer BW housings have CM identifiers on them I think it is the 1.58 that lines up with a 36cm, so 40 would be similar to a 1.65.
