Our investigation continues in the ield of cooling systems adopted on karts and, specfically, on water pumps. On this occasion we had the opportunity to test the products of a company renowned in this sector, namely New Line. The company of Maranello is in fact specialized in the production of radiators of various shapes and sizes, and attached to these are also various accessories, from pipes to water pumps, in fact. To be precise, two models are proposed: R-OR and R-HTD which, as the abbreviation reveals, differ only in the drive system adopted: an o-ring or a toothed belt.
