We have commercialized a prototype for race engine development. By brushing up the impeller shape, a high flow rate that exceeds not only the STD but also the N1 specifications is realized, and the cooling Upgrade is improved by increasing the amount of circulating water in the radiator. It also leads to further improvement in cooling efficiency of sports radiators with increased capacity.
