Performance & Application
This CHRA is designed for high-performance builds that demand quick spool combined with strong sustained power delivery. The dual ball bearing design reduces spool lag compared to journal bearing alternatives, giving the turbine wheel a faster response to throttle input. Paired with the 71.5mm compressor wheel and 90-trim turbine wheel, this cartridge is suited for builds targeting serious power gains while retaining responsive boost characteristics. It serves as a high-flow core replacement for platforms already running the compatible turbo assemblies.
