Performance & Application
This turbo is purpose-built for high-horsepower applications where strong top-end flow and reliable spool characteristics matter most. The T4 undivided turbine housing paired with the .81 A/R ratio is tuned to balance response with the flow capacity needed to support serious power goals. The T04S compressor frame, complete with built-in and machined anti-surge technology, helps extend the usable compressor map for a broader powerband. This configuration is well-suited to enthusiasts building toward the upper end of the 900 HP potential flow rating who want GTW-series reliability without stepping up to a larger frame turbo.
