Hmmm.
This might be the answer for my choking problem, but at $700 for the housing, plus probably another few hundred for GCG to re-machine to suit the existing turbine wheel, it could become to expensive to be viable.
This is a very interesting thing though.
I will soon be fitting a multi temperature display (from MearCat) to my car and will be able to view Ambient, After Turbo, After Intercooler and Exhaust Gas temp all at once, so I will be taking careful note of the boost level from my high flow where the After Turbo air temp begins spiking, to see whether the compressor side can take any more boost.
If it doesn't run out of puff before the turbine housing runs out of flow, then there is potential for this housing to be trialled.
However, if the compressor is all out of air before the turbine chokes up, then we have reached the limit on the standard compressor side housing.
Food 4 thought.
