Raceseng Revo Water + Alternator

Introducing Revo Water + Alternator

Raceseng is proud to introduce the Revo Water + Alternator, a lightweight, performance pulley. Form and function unite to create a pulley packed with performance, design, engineering, and quality throughout.

The Diet

We set out on a mission to put the water and alternator pulley on an extensive diet using advanced product design and CAD modeling techniques. The goal was to achieve the following:

1 | Reduce overall mass 2 | Reduce the moment of inertia 3 | Maintain superior strength

Engineering The Diet

The pulleys was run through extensive FEA simulations to determine where we could remove material without sacrificing the structural integrity of the pulley.

Testing The Diet

Validating our design and engineering assumptions is critical to finalizing product development. The pulleys were tested in both harsh winter conditions and the extreme heat of summer extensively. They were tested both on the street and put through heavy track use validating the quality of the engineering and materials used.

The Result

The Revo Water + Alternator weighs .46 lbs. less than the OEM water + alternator and delivers a 35% reduction in rotating mass. The design keeps the mass as close as possible to the center of the pulley, requiring less torque to spin the pulleys and delivering more power to your wheels. You will feel improved throttle response and faster revs!

OEM Water + Alternator | 1.44 lbs. Revo Water + Alternator | .98 lbs.

Precision Manufacturing

Each Revo Water and Alternator starts out as a solid block of USA milled 6061 T6 Aluminum. We precisely cnc machine the pulleys through turning and milling operations to sculpt the final design. The precision manufacturing tolerance results in a perfectly balanced pulley.

The Final Touch

After machining, the water and alternator pulley are anodized with our proprietary process to produce a rich color and prevent corrosion. The final touch is our signature ring and icon engraving giving this pulley a unique look like no other.

Crafted by Racenseng

For the integrity and craftsmanship of our products, we do our manufacturing in house. We are proud to get our hands dirty crafting the very products we create.
