Genuine Garrett 57 Trim/ Stg Iii Water-cooled, Blueprinted T3/t4 Chra on 2040-parts.com

Garrett TO4E 57 Trim/ Stage III Water-Cooled Blueprinted CHRA (450 HP)

     Here we have a special water-cooled and blueprinted CHRA for a 57-trim hybrid Garrett turbocharger.  Exclusive Turbosystems applies its proprietary tweaks to the turbine shaft, backing plate, bearings and thrust plate.  No component is left un-touched.  The STG III turbine shaft has polished journal surfaces for low friction contact with the bearings.  Both shaft support bearings have a full circumference oil groove to provide 360 degree lubrication of the turbine shaft journal surface.  Thrust plate receives modified oil ports for increased lubrication flow and cooling capacity.  It also has its surfaces polished for reduced friction and vastly improved thrust load capacity.  The combination of these modifications results in an impressive 35% reduction in internal friction and a corresponding drop in spool-up of the rotor group.  No other turbo manufacturer offers such a combination of improvements in CHRA bearing dynamics.  We also fully polish the backing plate surface adjacent to the compressor wheel exducer so that airflow has an ultra-smooth path into the housing chamber.  This particular CHRA is equipped with a water jacketed bearing housing for ultra-low bearing temps during operation.  This popular option is the hot ticket for durability because it keeps the turbocharger bearings from heat induced damage while coolant is being pumped through its passages.  Even the turbine shaft oil seal is a specially selected staggered-gap design for reduced oil pollution of the gas flow and potential carbon build-up.  Not your average 57-trim CHRA here!  The turbine shaft, compressor wheel, backing plate, and bearing housing are all GENUINE GARRETT parts.  Will only work in genuine garrett turbine and compressor housings.  Will spool up about 150 rpm sooner than a factory CHRA of the same specification and will yield a 5 HP gain as well.  Ported housings will improve these numbers further.  Feel free to ask us about providing this service as well.
