Any vehicle using higher rpm than envisaged by the manufacturer needs an oil cooler. The oil cooling requirement of an engine increase threefold for every 1000 rpm increase. Oil, when heated, starts to lose film strength, i.e. the ability to keep metallic surfaces from touching, when the film strength is insufficient to withstand the load, seizure and bearing failure can occur.
