Racing coolant improves heat transfer away from cylinder heads
VP Racing Fuels

VP Racing developed Stay Frosty Race Ready as a proprietary racing coolant. Not only is it formulated for high-compression, high-heat racing engines, but the racing coolant contains a specialized blend of heat transfer agents that drastically improves the coolant’s ability to transfer heat away from high-temperature cylinder heads. This both increases the density of the air/fuel mix and allows ignition timing to be safely advanced without the threat of detonation. Consequently, cars get more power and torque.

Stay Frosty Race Ready reduces cylinder head temperatures by an average of 62°C as compared to waterless engine coolant. It also reduces engine cylinder head temperatures by an average 43°C as compared to a conventional 50/50 mix.

The waterless engine coolant is composed of 100% glycol while Stay Frosty is a 100% water-based formula. Water transfers approximately twice the heat glycol does. The viscosity of glycol is 10 times higher than water; the viscosity of a 50/50 mix is three to six times higher than water. High coolant viscosity reduces flow rate, which further elevates temperatures unless a high-flow water pump is installed.
