Performance & Application
The GTX4088R’s twin-scroll turbine housing design is suited to applications where exhaust pulse separation is used to improve turbine response, making it a strong candidate for high-output builds that still value driveability. Its dual ball bearing architecture delivers the fast response and durability required for aggressive power targets, while the ported shroud compressor inlet extends the usable range of the compressor map against surge. With potential flow supporting output beyond 850 horsepower, this turbocharger is intended for builders pushing well past stock power levels into serious performance territory. The 3″ V-Band turbine outlet and .72 A/R compressor housing round out a configuration built for high-flow, high-boost applications.
