///Dynostar SR38

Dynostar SR38

SINGLE ROLLER, MULTI PURPOSE

The SR38 is our 2WD equivalent of the W4-X. Built with the same philosophy as the W4-X, no compromises. This dyno is built for the most demanding. High power, high speed, superior materials and quality, it’s all there. The 800mm drums guarantee a smooth drive with a maximum grip due to its Tungsten Carbide coating. Equipped with the most powerful eddy current brake available, its brake capacity is a staggering 3800 Nm of torque. With its low profile it is the ideal dyno for extremely lowered cars, down to 60mm ground clearance.

The SR38 is designed using 3D-CAD and FEM analysis to deal with the high power and speed it’s intended for. Laser alignment by SKF, balancing on our own Schenck balancing machine, vibrations are reduced to a minimum assuring very accurate measurement and virtually maintenance free operation. Assembled by hand by a small but very skilled group of professionals, quality is in its DNA!

Because of its height the SR38 must be integrated into the workshop floor.
