Overview 

The PSR 7975G Forward Rotation Dual Ball Bearing Turbocharger is engineered to deliver up to 1450 horsepower, making it ideal for extreme-performance street and motorsport applications. It features a dual ceramic ball bearing system that enhances durability, improves spool-up speed, and reduces friction for reliable high-speed operation. The turbo is equipped with a large 79mm x 98mm billet compressor wheel and an 82mm x 75mm Inconel turbine wheel, optimized for maximum airflow and thermal resistance. The compressor housing includes an anti-surge ported shroud and a built-in speed sensor port to maintain boost stability and allow for precise turbo speed monitoring. This variant comes with a T4 divided turbine inlet and a 0.95 A/R turbine housing, delivering a strong balance between fast spool and top-end power. A V-band outlet provides a secure, leak-free connection and easier installation. Additionally, the turbo includes -6AN water ports for cooling, a -4AN oil feed (non-restricted), and a -12AN oil drain with an O-ring sealed flange, ensuring proper lubrication and thermal control under demanding conditions.
