Power Distribution Modules
Racepak power distribution modules for motorsport, track day and performance cars
Power distribution modules from Racepak are developed for drivers, teams and vehicle builders who want a more modern and intelligent solution for the vehicle’s power management than a traditional fuse box and relay setup. With a Racepak SmartWire power distribution module, you get a central unit that acts as the electrical starting point of the vehicle, where power distribution and control are gathered in one programmable solution. This makes Racepak power distribution modules relevant for everything from motorsport and track day use to drag racing, offroad and advanced performance projects. Racepak itself describes SmartWire as the easiest way to wire a vehicle while adding modern electronic functions.
Why choose a Racepak power distribution module?
When you build or optimise a race car or performance car, it is not only the engine and chassis that matter. The electrical system must also be reliable, easy to understand and easy to control. A Racepak power distribution module replaces many of the functions that would normally be handled by separate fuses, relays and wiring branches, and gathers them in a more intelligent solution. Holley itself explains that SmartWire works as the central power distribution for the entire vehicle wiring harness, and that each input and output can be programmed individually with function, current requirements and overcurrent limits. This gives the customer far more control over the vehicle’s electrical system than a traditional wiring setup.
Less wiring clutter and more control
One of the major advantages of Racepak SmartWire is that the system is designed to reduce wiring clutter and make the installation more compact. Racepak itself highlights that the design reduces both total installation weight and wiring clutter, while also allowing the system to react faster through solid-state switching. For the customer, this means a more organised electrical system, fewer traditional components and a better opportunity to build a clean and professional installation. This is especially important in motorsport and performance cars, where space, weight and serviceability play a major role.
The advantage of solid-state power management
Racepak itself emphasises that a PDM replaces a traditional fuse box with solid-state electronics. This gives a clear advantage in vehicles exposed to vibration, load and harsh conditions, because solid-state relays and transistor-based switching do not have moving parts in the same way as traditional relays. At the same time, Holley explains that if a circuit in a traditional setup loses its fuse, it is out of service until you stop and replace it. With SmartWire, the customer instead gets a far more flexible and programmable power management solution.
Programmable solution for both simple and advanced vehicles
Racepak power distribution modules are not only for dedicated race cars. Racepak offers both street- and drag-oriented SmartWire solutions, and they describe the system as suitable both for full wiring of the entire vehicle and for power control of extra equipment such as fans, lights and radio. At the same time, SmartWire can be expanded with a switch panel, keypad or switch module, and Racepak highlights that V-Net compatibility provides seamless integration with existing Racepak V-Net equipment. This makes the solution relevant both for customers building from scratch and for customers who want to upgrade an existing setup.
Racepak power distribution modules for customers who want to build the vehicle properly
For customers who want a more professional electrical system, Racepak power distribution modules are an obvious choice. When power management, functions and protection are gathered in one programmable unit, it becomes easier to control the vehicle’s electrical components, easier to keep the installation clean and easier to adapt the system to future changes. That is why Racepak SmartWire is relevant for customers looking for a PDM for motorsport.
