Hi-Flow water impeller kit TM 450-530 (Silver)
Kit developed in races and on track to increase coolant flow all RPMs (specially for 450 SMK engines from 2022)
Thanks to the bigger impeller and revised geometry of the water pump cover the engine works at 8/10 °C lower than the original setting, thus reducing power loss from middle/end of the race and minor wear of the engine components in extreme heat conditions.
Impeller and cover are both are cnc machined from billet in aluminum with a finned surface wich matches perfectly our clutch cover
The kit includes fixing bolts, silicone hose and gasket
