Description

Kraftwerks Rotrex Supercharger Ribbed Pulley (R50-99-0075)If you want your ROTREX supercharger work more efficiently, then it is vital to provide it with ROTREX or KRAFTWERKS pulleys as they will improve your vehicle performance. The supercharger compresses the air into the combustor and the pulley enables its spinning, so the faster the supercharger spins the more air will be compressed. That's why having a proper pulley will provide a pressure boost and therefore will increase the supercharger efficiency.

If you want your ROTREX supercharger work more efficiently, then it is vital to provide it with ROTREX or KRAFTWERKS pulleys as they will improve your vehicle performance. The supercharger compresses the air into the combustor and the pulley enables its spinning, so the faster the supercharger spins the more air will be compressed. That's why having a proper pulley will provide a pressure boost and therefore will increase the supercharger efficiency. Rotrex recommends to use standard pulleys, just check your data sheet to see the appropriate size for your particular supercharger. But, if your supercharger needs for some reason a custom design, then you can get the pulley adaptor.

  • Provide an increase in efficiency and performance
  • Rotrex superchargers specific
  • Pulley adaptor available
  • Rotrex superchargers come preassembled with pulley/ pulley adaptor to eliminate problems with assembly

Sturdy & easy to move around
Its solid & sturdy. It does exactly what it’s supposed to. You have the option to fill it up with water or sand , I choose water. It holds the umbrella in place. The wheels and handle make it really easy to move around, which is a huge plus. It fits perfectly and feels very well made. Great addition for my pool area!

Heavy-Duty Base with Convenient Mobility
This umbrella base does exactly what it’s supposed to—keeps the umbrella stable while still being easy to move around when needed. Once filled with water/sand, it feels solid and secure even on slightly windy days, which gives peace of mind. The built-in wheels are a standout feature. Moving the base across the patio is smooth and doesn’t require much effort. The handle placement is well thought out, making repositioning quick and hassle-free. Overall, it’s a great balance of stability and convenience. Highly recommend if you want a sturdy base without sacrificing mobility.

The base that fits!
Finally, easy to put together and the right fit just before summer. It was extra windy so I put extra weight.
