Info

Plus, high RPM water pump operation is improved due to reduced fluid cavitation.
- Machined from lightweight cast aluminum
- Superior belt retention with extra-deep grooves
- 20% reduction slows accessories down for less drag
- Adds top-end horsepower
- Reduces water pump impeller speed below cavitation threshold
- Improved high-RPM cooling capabilities
