LC+α Water Pump Pulley: SR20
Part Number: HPWP-SR20
Compatibility: Nissan SR20DET / SR20DE
Outer Diameter: Approx. 15% Increase over OEM
Description: Experience the next generation of cooling technology with the HPI LC+α Pulley.
Designed specifically for high-performance SR20 engines, this pulley tackles cooling from two revolutionary angles: cavitation prevention and active air cooling.
The name "LC" stands for Low Cavitation.
By increasing the pulley's outer diameter by 15%, it reduces the excessive rotation of the water pump at high RPMs.
This effectively prevents cavitation (bubble formation), ensuring consistent coolant flow even under grueling track conditions.
The "+α" represents the unique integrated Inner Cooling Fins. These fins generate a powerful airflow that cools the water pump body and forces trapped heat out of the radiator shroud, significantly improving the overall thermal efficiency of your engine bay.
Key Features:
Advanced Cooling Design: Integrated inner fins actively evacuate hot air from the engine bay.
Low Cavitation Technology: Oversized diameter prevents water pump frothing at high engine speeds.
Superior Strength: Engineered with a specialized lightweight aluminum design that offers top-class structural integrity.
Hard Anodized Finish: Coated with a premium hard-anodized layer for enhanced surface hardness and long-lasting durability.
