MSV Racing High-Flow Water Pump Impeller & DLC Shaft Kit for Yamaha Banshee

✔ Up to 20°F Cooler

✔ +2.0 GPM More Coolant Flow Than OEM

✔ DLC-Coated Shaft That Will Never Wear Out

The Yamaha Banshee is legendary for making power—but every horsepower creates heat.

The MSV Racing High-Flow Impeller & DLC Shaft Kit was engineered to dramatically improve coolant flow, reduce operating temperatures, and help prevent power-robbing heat soak in both stock and modified Banshee engines.

Flow bench testing showed the MSV Racing design outflows OEM and competing aftermarket impellers while reducing operating temperatures by up to 20°F.

Proven Benefits

✔ Up to 20°F Lower Engine Temperatures

✔ Up to 2.0 GPM More Flow Than OEM

✔ Up to 1.5 GPM More Flow Than Competing Aftermarket Impellers

✔ Reduced Heat Soak

✔ Improved Cooling Efficiency

✔ DLC-Coated Shaft for Extreme Durability

✔ Includes Bearing and Gasket

✔ Direct Bolt-On Installation

Why Cooling Matters

Every horsepower added to a Banshee creates additional heat.

For every 1 HP added beyond stock output, approximately 2,500 BTUs of additional heat are introduced into the cooling system.

A modified Banshee producing 25 additional horsepower can generate over 62,500 additional BTUs that the cooling system must remove.

When coolant temperatures climb, power begins to fall.

The goal is simple:

Keep temperatures down and horsepower stays up.

More Coolant Flow = More Cooling Capacity

The MSV Racing Impeller was designed to optimize the Banshee water pump housing and maximize coolant flow throughout the RPM range.

Flow testing demonstrated:

Flow Comparison

OEM Impeller = Baseline

MSV Racing Impeller = +2.0 GPM Average Flow Increase

Competing Aftermarket Impellers = Lower Flow

MSV Racing Impeller = +1.5 GPM Average Flow Increase

Increasing coolant flow reduces the cycle time between the engine and the radiator, allowing heat to be removed more efficiently.

The result is lower temperatures and more consistent performance.

Engineered for Maximum Efficiency

Several key design improvements make this possible.

Optimized High-Flow Impeller

Precision-machined from premium 7075-T6-511 aluminum, the impeller was specifically designed to maximize flow and efficiency within the Banshee water pump housing.

Precision Ground Stainless Steel Shaft

The shaft is manufactured from premium 304 stainless steel and incorporates a reduced-diameter cooling-port section developed through FEA analysis.

Benefits include:

• Improved coolant entry into the impeller
• Reduced turbulence
• Reduced backpressure
• Increased flow efficiency
• Exceptional strength

DLC-Coated Shaft Technology

Unlike conventional shafts, the MSV Racing shaft receives a Diamond-Like Carbon (DLC) coating.

Benefits include:

✔ Extreme Wear Resistance

✔ Self-Lubricating Surface

✔ Reduced Seal Drag

✔ Longer Seal Life

✔ Corrosion Resistance

✔ Virtually Zero Shaft Wear

The DLC coating measures approximately 2500 HV on the Vickers hardness scale—more than three times harder than many heat-treated steels.

Simply Put:

The shaft is engineered to last the life of the machine.
