dynojet 424xlc2-above02


The 424xLC2 features 2 x 24″ knurled, precision balanced drums, 2x Eddy Current Load Absorption Units, measures up to 2000 HP, 2000 FT LBS, 200 MPH, and is capable of 1600HP peak absorption (in AWD) making it the most powerful load control dynamometer on the market.

Unlike inferior non adjustable wheelbase designs, the model 424xLC2 can adjust wheelbase with a push of a button from 88” to 140”. This allows the tires to contact the rollers evenly and in conjunction with the large drum diameter the 424xLC2 provides a virtually flat, stable surface for tire contact eliminating unnecessary tire slippage and deformation. The result is precise, repeatable data every time.

The 424xLC2 can operate in “inertia only” mode for assessing gains from minor bolt-on modifications, or utilize the duel eddy currant load absorption units for advanced load testing. Load tests include step, sweep and custom road-load profiles in all gears and at any throttle position. This system also eliminates any potential speed bias between the two drums when using the Dynojet speed balance feature.

Horsepower and torque are measured at each drum and can be displayed and/or logged independently or combined. This feature allows you to assess the vehicle’s power-split and can also aid in troubleshooting drive-train issues.

With the addition of the optional Linx System, the 424xLC2 allows you to test modern AWD vehicles without the fear of potentially damaging the center differentials, or activating intrusive stability control systems. It is also useful for those 2wd performance vehicles that require all four wheels to be rotating in order to avoid “reduced power mode’’.
