Precision. Power. Control.
The Vector-X4000 Hub Dynamometer is the next generation in hub dynamometer technology, built for professional tuners, performance shops, and R&D engineers who demand absolute accuracy and repeatability. Designed and manufactured in the USA, it delivers the control, data resolution, and durability required to validate performance safely at the highest levels.
Advanced Power Management
The Vector-X4000 integrates torque, load, and rotational force control into a single system. This ensures every test run provides consistent and repeatable data—critical for professional tuners and R&D teams looking to validate performance gains on high-output engines.
Massive Absorption Capacity
Rated for up to 300 MPH, 4,000 lb-ft of torque, and 2,000 horsepower, the Vector-X4000 hub dyno handles everything from street cars and UTVs to race-prepped ATVs. Whether you’re a motorsports shop in California, a research lab in Detroit, or a performance facility overseas, the Vector-X4000 gives you room to test without limits.
Vector Measurement Technology
Unlike traditional dynos, Dynojet’s 360° vector measurement captures rotational forces directly at the wheel hub. This delivers a true picture of drivetrain dynamics and “power at the hub” performance, making it ideal for chassis builders and OEM validation work.
Mobility Built In
Despite its heavy-duty performance, the Vector-X4000 is designed for shop flexibility. Built-in wheels and a compact footprint make it easy to reposition, set up, or store, even in smaller facilities where floor space is at a premium.
High-Speed Data Acquisition
With sampling rates up to 45,000 Hz, the Vector-X4000 captures every detail of torque, RPM, and horsepower output. This level of resolution is invaluable for diagnosing drivetrain issues, refining EFI maps, and proving gains in competitive markets like automotive tuning, UTV racing, and powersports.
Durable - Designed, Engineered, and Built in The USA
Manufactured and supported in Montana, United States, the Vector-X4000 uses industrial-grade bearings and a reinforced chassis designed to withstand years of heavy commercial use. This durability ensures reliability for dyno facilities worldwide, from small performance garages to large-scale OEM test centers.
Power Core Integration
-
Every Vector-X4000 ships with Dynojet’s Power Core software suite, featuring hub-specific testing routines, real-time graphing, and advanced data logging. Engineers and tuners can customize sessions, export results, and compare runs instantly—streamlining R&D and customer reporting.
