Rolling Road Dyno Days

Bring your car club, tuning group, or enthusiast community together with our Rolling Road Dyno Days in Slough. Designed for those who love performance, our dyno events provide back-to-back power runs, live tuning demonstrations, and accurate performance printouts for every car tested.

Using our in-house 2WD & 4WD rolling road dyno, we can measure horsepower, torque, and power delivery with precision. Perfect for modified builds, performance saloons, hot hatches, luxury cars, and supercars, our dyno days are about more than numbers — they’re about sharing the experience with fellow enthusiasts.

Based in Slough, near Langley, Berkshire, our facility is a hub for car clubs, performance groups, and tuning fans across the UK who want professional dyno testing in a social, event-style atmosphere.
