Xona Rotor has implemented innovative features in its XR line of performance turbochargers to enhance performance and durability.

Product Details

Compressor Map

Xona Rotor's compressor maps are generated using the industry-leading CFD package ANSYS CFX, and validated with experimental data and testing.

Next-Generation UHF Turbine

Xona Rotor's all-new, proprietary UHF (Ultra High Flow) turbine wheel is already resetting the bar for turbocharger performance. UHF's splitter-blade design allows it flow like a larger-diameter wheel without the associated inertia penalty. The result is superior boost response and less power-robbing backpressure.

Dual-Row Ball Bearing Cartridge

With silicon nitride ceramic balls, M62 tool steel races and metallic cages, Xona Rotor's dual-row ball bearing cartridge ensures robustness to the most extreme operating conditions. This exclusive bearing system was engineered in cooperation with one of Germany's most prestigious manufacturers of high-precision rolling-element bearings.

CNC-Machined Billet Stainless Steel Center Housing

The workhorse of every Xona Rotor turbocharger is a fully-machined, high-strength 17-4PH stainless steel center housing with a true 360-degree water jacket. By fully surrounding the turbine seal ring land area with coolant, this center housing enhances durability by preventing piston ring collapse at high temperatures.

Dual Piston Rings

Most performance turbochargers today use a single piston ring for sealing the shaft at each end. By contrast, Xona Rotor turbochargers employ twin rings at both the compressor and turbine ends, dramatically reducing oil leakage and gas intrusion. Spreading the sealing load across two rings also slashes wear rates and extends seal life.

Integrated Oil Filter and Modular Oil Drain

Built into the oil inlet cavity of Xona Rotor center housings is a large-volume “last ditch” oil filter element. This feature protects the bearing system from oil contaminants, ensuring long bearing life. On the oil discharge side of the center housing is a modular oil drain surface with provision for a variety of bolt spacing configurations.

Modular Compressor Housing

Several compressor housings with different inlet and outlet dimensions allows packaging flexibility to suit the most demanding installations.

Turbine Housing Choices

All of these turbine housings are a proprietary austenitic stainless steel with high nickel content. Investment cast to minimize weight yet can cope with temperatures up to 1,900 degrees F.
