PROHUB PORTABLE 2WD AXLE SHAFT CHASSIS DYNAMOMETERS

UNLEASH YOUR VEHICLE’S TRUE POTENTIAL  

Take your tuning to the next level with the Mainline Portable ProHub CCS (CAN Control System) Chassis Dynamometers — the ultimate “in-chassis” solution for extreme streetcars and drag machines. Designed for high-performance testing, the ProHub delivers precision, power, and flexibility that bridges the gap between engine dynos and traditional roller chassis dynamometers.

Available in 2000hp and 3000hp models, the ProHub is fast to set up, easy to move, and simple to store — perfect for workshops, garages, or race paddocks. Use it for performance tuning, ignition timing fine-tuning, pre-race preparation, driveline torque checks, clutch evaluation, nitrous testing, and R&D of performance products.

Need more capability later? Portable ProHub models can be upgraded to AWD, giving you the ultimate in testing versatility as your vehicles and projects evolve.

Power. Precision. Portability. That’s the ProHub difference.

NON-COAXIAL DESIGN  

All Mainline ProHub Chassis Dynamometers feature a non-coaxial design. This means the Power Absorption Modules (PAMs) sit flat on the floor, eliminating the need to adjust module angles to match a vehicle’s camber. The result is a faster, simpler setup compared to coaxial designs used by competitors, which can be prone to vibration when modules are misaligned.

Our non-coaxial layout ensures that module alignment relative to the vehicle—vertically or laterally—is not critical. Additionally, ProHub units feature a twin Constant Velocity (CV) joint arrangement within the module extension tubes. The retarders inside the modules are deliberately offset, making it impossible for the connection to the vehicle to be coaxially aligned, further enhancing reliability and stability.

The Portable ProHub 2WD Dynamometer connects directly to the vehicle’s axle hubs using billet steel adapters, eliminating wheel and tyre-related variables. This ensures absolute accuracy and delivers unmatched repeatability from one power run to the next.

Portable ProHub dynamometers can accommodate ±10° of camber and 10° of toe-in/out, making them compatible with both live axle and independent rear suspension (IRS) systems.

HIGH-SPEED OPERATION

All 2WD Portable ProHub CAN Control System (CCS) models are rated for maximum speeds of up to 5,000 axle RPM, or road speeds of up to 400 mph (640 km/h), depending on the vehicle’s gearing. The Power Absorption Modules (PAMS) on the 2,000 hp and 3,000 hp models feature integrated wheel assemblies, allowing them to be easily positioned at the vehicle, accurately aligned, and quickly connected to the axle hubs. Once testing is complete, the PAMS can be conveniently rolled away and stored.

CAN CONTROL SYSTEM (CCS)

The new Mainline CCS (CAN Control System) represents the next level in sophisticated dynamometer control and precision data acquisition.

Built on a robust and reliable CAN communication network, the CCS connects a central control unit to one or multiple remote CAN control units. This design delivers faster data transfer, quicker control response, and heightened sensitivity to transient or intermittent data changes. Combined with emerging hardware and software innovations, the system meets the exacting standards of the most discerning operators.

ADVANCED DYNAMOMETER CONTROL STRATEGIES  

The Mainline CCS (CAN Control System) represents the pinnacle of dynamometer control technology, delivering exceptionally fast, accurate, and precise vehicle management during testing. Designed for high-performance applications, it ensures that every run produces reliable, repeatable, and meaningful data.

Eddy Current Brake Mapping: At the heart of the system, Mainline CCS dynamometers feature fully mapped eddy current retarders. Each retarder’s performance is meticulously characterised under all expected operating conditions, allowing the system to implement a fully optimised control strategy. The result is unparalleled precision, consistent braking behaviour, and complete confidence in every test mode, whether for tuning, validation, or performance benchmarking.

Combination Feedforward & PID Control: This advanced control system proactively anticipates changes in demand or torque, reducing the error correction workload typically handled by a traditional PID (proportional, integral, derivative) controller. Simply put, the dynamometer controller focuses on upcoming control challenges rather than reacting to past performance, enabling it to respond quickly to load adjustments and precisely match the performance characteristics of the vehicle under test.

ADVANCED MODES OF OPERATION

The Portable ProHub CCS Chassis Dynamometers offer highly advanced and versatile modes of operation, including:

• Fixed Speed – Steady state control for consistent speed testing.

• Fixed Torque – Variable speed with a fixed load or torque control.

• Drive Test / Road Load Simulation – Simulates real-world conditions based on vehicle weight and aerodynamic coefficients.

• Linear Ramp Test – Gradually increases load or speed in a linear progression.

• Non-Linear Ramp Test – Applies a ramp with variable progression for more complex simulations.

• User-Definable Non-Linear Ramp – Allows custom ramp profiles tailored to specific testing requirements.

• Drag Strip Run Data Download & Run Simulations – Capture and replay drag strip performance data.

• Drag Mode – Measures performance over distance or time, considering vehicle weight and aerodynamic coefficients, with staged start and time slip analysis at completion.

• Torque Balancing / Vectoring – Adjusts torque distribution between left and right sides for precision testing and performance tuning.
