We have an all-wheel drive capable chassis dynamometer system. The Dynoproject dyno allows for precise measurements, performance comparisons and engine loading for diagnostics.

The facility may be used by Subaru and Mitsubishi road car owners, rally and race teams as well as owners of 1000bhp dragracers. The facility makes enables us to study functioning of car's control systems, develop engine mapping and even run-in cars that may not be run on public roads. All engine modifications carried out by 4turbo are confirmed by data from the dyno. Bacause of that the risks taken during road testing are reduced to minimum. Your car seems underpowered? You need to map a competition car?
