Pro Xe PX350 P1 Volvo S40 C30 V50 C70 Hybrid Turbo Upgrade

Pro Xe Automotive PX350 Hybrid Turbo Upgrade

P1 Volvo T5 / P3 S60 T5 Performance Hybrid Turbo

The Pro Xe PX350 Hybrid Turbo is a direct bolt-on performance upgrade for Volvo P1 T5 (C30, S40, V50, C70) and P3 S60 T5 platforms. Designed around the factory BorgWarner K04 frame, the PX350 focuses on maximizing the efficiency of the stock turbocharger while retaining exceptional spool characteristics, drivability, and OEM-style fitment.

Unlike larger hybrid turbos that prioritize peak horsepower at the expense of response, the PX350 was engineered to enhance the factory K04’s strengths. Utilizing an OEM-sized lightweight billet compressor wheel paired with an OEM-diameter lightweight turbine wheel, the PX350 delivers quicker-than-stock spool, increased midrange torque, and improved overall turbo efficiency.

The result is a turbocharger that feels sharper and more responsive throughout the rev range while supporting substantial gains in power and torque.

HOW IS IT UPGRADED?

Every Pro Xe PX350 Hybrid Turbo is completely disassembled, inspected, machined, ported, coated, balanced, and assembled in-house.

Each unit features:

• OEM-size lightweight billet compressor wheel
• OEM-diameter lightweight high-efficiency turbine wheel
• Upgraded journal-bearing CHRA components
• Optimized bearing clearances for improved oil control and durability
• Fully machined compressor and turbine housings
• Extensive compressor inlet and outlet porting
• Ported turbine volute, inlet throat, wastegate passage, and outlet
• Ceramic-coated housings for improved heat management

Every turbocharger is high-speed VSR balanced to 150,000 RPM and tested prior to shipment.

WHY A PX350 HYBRID?

The factory K04 responds exceptionally well to airflow and efficiency improvements. The PX350 was specifically designed for enthusiasts seeking a turbocharger that spools even faster than OEM while producing stronger torque through the midrange and maintaining excellent top-end efficiency.

Compared to larger hybrid configurations, the PX350 offers:

• Faster-than-OEM spool characteristics
• Increased midrange torque
• Improved compressor efficiency
• Reduced exhaust backpressure
• Lower exhaust gas temperatures
• Enhanced throttle response
• OEM-style fitment and drivability

WHY PRO XE?

Many hybrid turbo builders focus primarily on increasing wheel size to chase peak horsepower figures. The PX350 takes a different approach by optimizing the entire K04 system through extensive turbine-side porting, carefully matched lightweight rotating components, and refined flow paths.

The result is a highly responsive hybrid turbocharger that delivers a broader, more usable powerband while preserving the quick-spooling nature that makes Volvo’s K04-equipped platforms so enjoyable to drive.
