    Speedway's adjustable water pump is tried, tested and true. It has great flow, superior quality and standard features that are typically only available on water pumps costing twice as much. State-of-the-art aluminum casting and a precision impeller provide equal flow to both cylinder banks. If you're using a cog belt on your race car, this is the pump you want since it's adjustable. The 1/2" mount holes in this pump are larger than normal, allowing it to be moved up or down slightly to help with belt tension.
    • Adjustable mounting holes 
    • High flow and pressure rates 
    • Adjustable cam stop 
    • Extra-thick fan hub 
    • 3/4" inch heavy duty bearing 
    • Pressed-fit and set-screw-retained fan hub 
    • Large-diameter shaft and reinforced housing make it ideal for oval-track applications
