WATERPUMP COVER & IMPELLER KIT BLACK
SKU: WPK-06DB
Easy — 1–2 hours
Overview
Excessive engine heat can lead to component damage and reduced horsepower. Boyesen's Hyperflow Integration (HFI) design process optimizes water pump systems by enhancing inlet capacity, interior surface modeling, and impeller design. This results in superior fluid flow rates, increased hydrodynamic efficiency, and better heat management.
The Supercooler features a hydrodynamically optimized impeller that increases coolant flow and virtually eliminates cavitation. Its larger Max Inlet opening improves coolant re-entry into the engine, allowing more coolant to absorb and dissipate heat, ultimately optimizing power characteristics and protecting the engine from overheating and potential damage.
