Genuine Garrett V-trim/ Stg I Blueprinted T3/t4 Chra on 2040-parts.com

Garrett TO4B V-Trim/ Stage I Blueprinted CHRA (450 HP)

       Here we have a specially blueprinted CHRA for a V-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 I 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.   One of the modifications that sets this CHRA apart from others is the inclusion of a full 360 degree thrust plate and collar set.  This ensures durability with elevated boost loads that usually accompany motorsports use.  The thrust plate also receives modified oil ports for increased lubrication flow and cooling capacity.  It even has its surfaces polished for reduced friction and further 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 scroll outlet chamber.  We have worked some magic with this V-trim CHRA for sure! 

       This CHRA is full of GENUINE GARRETT parts so you can be sure of its performance, fit, and durability.  Will only work in genuine garrett turbine and compressor housings.  These compressor wheels excel in efficiency at modest boost pressures in between 15 psi and 25 psi.  Really smooth midrange performance with this hybrid rotor group.  As tweaked by us at exclusive Turbosystems, it 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.
