The R Racing Cool is developed to help minimising "hot spot" problems within cylinder head designs. Typically more or less all cylinder heads have areas where the coolant's flow rate is lower and therefore the coolants ability to cool this area creates hot spots which will cause localised boiling. When water boils you get very large air bubbles which basically stops the flow of the coolant and results in an accelerated temperature increase.

The R Racing Cool will reduce the surface tension minimising the creation of large air bubbles hence supporting the flow of the coolant. In addition it helps to dissipate heat. It also contains a lubricating and anti-corrosion additive and can therefore be run without anti-freeze.

Reduces risk of detonation, boiling and powerloss. The R Racing Cool should be used by all racers. 250 ml will treat 12 litres of water.
