The Tipton Garage’s MAHA four-wheel drive rolling road can cope with engine outputs as high as 350 bhp per axle and is in regular use for fine-tuning competition, modified road and sports cars. Any vehicle can benefit from tuning under simulated road conditions within the controlled environment of the rolling road. The dynamometer provides an efficient way of monitoring the effectiveness of engine improvements, enabling final adjustments and ‘fine tuning’ to be carried out without having to leave the garage. An hour’s work on the rolling road costs little yet can bring huge benefits in fuel savings and performance. Our rolling road is integrated with SUN testing equipment which, as well as being essential for modern MOT testing, is used to ensure optimum results are gained from modifications. All the work on the rolling road is recorded by computer for printing and future reference. Other diagnostic and tuning tools include a Bosch KTS diagnostic platform, Hanatech, Sykes Pickavant and ASNU injector cleaning equipment.
