The Turbosmart TS-1-6466B-D4100E TS-1 6466 Turbocharger is engineered for high-horsepower applications that demand exceptional response, efficient exhaust flow, and proven durability. This exact configuration features a 64mm compressor inducer, 66mm turbine exducer, divided T4 turbine inlet, 1.00 A/R turbine housing, 3-inch V-band turbine outlet, and external wastegate configuration. Turbosmart rates the 6466 at approximately 825–955 horsepower, placing it squarely in the range for serious street, drag, roll-racing, and competition builds.
Part of Turbosmart's TS-1 oil-cooled turbocharger series, the 6466 uses a proprietary dual ceramic bearing system and ultra-low-mass rotating assembly to deliver outstanding transient response. Aggressive 7+7 splitter-style compressor wheel aerodynamics are designed to produce strong performance at lower shaft speeds, while Turbosmart's turbine design maintains airflow and power as engine load increases.
Premium materials throughout the turbocharger help it survive the extreme temperatures and shaft speeds associated with high-output engines. The TS-1 combines a lightweight 310S stainless-steel investment-cast turbine housing, 713C Inconel turbine wheel, lightweight aluminum compressor cover, CFD-developed housings, and VSR speed balancing. Turbosmart's overall design philosophy focuses on reducing backpressure while creating a turbocharger that is smaller, lighter, and faster-responding.

Divided T4 1.00 A/R Turbine Housing
- Part number TS-1-6466B-D4100E specifically identifies the divided T4, 1.00 A/R, externally wastegated version of Turbosmart's TS-1 6466. Turbosmart also offers the 6466 with other turbine housings, including a divided T4 0.84 A/R configuration and V-band versions, so the complete part number is important when matching the turbocharger to an existing manifold and performance goal.
- The divided or twin-scroll T4 inlet allows exhaust pulses to remain separated when paired with a correctly designed divided manifold. This arrangement can improve turbine energy utilization and transient response while retaining the flow capacity needed for high-horsepower operation. The 1.00 A/R housing provides substantial turbine-side flow for applications where top-end power and reduced backpressure are priorities.
6466 Performance
- The 64mm compressor and 66mm turbine combination gives this TS-1 a strong balance between response and high-RPM airflow. With Turbosmart's published 825–955 HP rating, it is capable of supporting serious power without requiring the larger physical footprint and rotating assembly of the company's 7170, 7275, or 7880 configurations.
- Actual horsepower and spool characteristics will depend on engine displacement, compression ratio, cylinder-head airflow, camshaft selection, fuel type, boost pressure, exhaust manifold design, intercooling, exhaust backpressure, and engine calibration.
Oil-Cooled TS-1 Architecture
- The TS-1 is Turbosmart's oil-cooled turbocharger platform. Its proprietary bearing and shaft combination is engineered around low rotating mass, while the dual ceramic bearing system and aggressive compressor aerodynamics are intended to improve transient response. Builders requiring an oil-and-water-cooled center section can instead choose the corresponding TS-2 platform; Turbosmart offers a TS-2 version of this same 6466 divided T4 1.00 A/R configuration.
Installation & Application
- The TS-1-6466B-D4100E is a universal performance turbocharger, not a vehicle-specific bolt-on replacement. Installation requires a compatible divided T4 exhaust manifold, appropriately sized external wastegate system, fabricated downpipe and charge piping, and properly configured oil-feed and unrestricted oil-return plumbing.
- Because this model is externally wastegated, wastegate size, quantity, and placement can be selected according to engine displacement, manifold design, exhaust flow, and desired boost range. For best results, the divided turbine housing should be paired with a properly designed divided manifold that maintains exhaust-pulse separation to the turbine inlet.
For builders looking for serious power without giving up response, the Turbosmart TS-1-6466B-D4100E 6466 delivers an excellent combination of 825–955 HP capability, a divided T4 1.00 A/R turbine housing, 64/66mm wheel combination, dual ceramic bearings, Inconel turbine construction, and oil-cooled simplicity in a lightweight, motorsport-focused package.
