Drag Racing - The Waterless Coolant Advantage

When considering which coolant to use for racing, the first thing to consider is whether or not it is track legal. Water might be the default, as glycols are generally not allowed because of slippery hazardous conditions that result if the coolant gets on the track. Under high temperatures, vapor forms, pressure builds, and boilover can occur.  If that coolant contains glycols, it becomes a dangerous and difficult mess to clean. The exception to the No-Glycol rule is Evans Waterless Coolants. The NHRA has approved Evans Waterless Coolant for use at the National and Divisional events. Wait, you might say, if it’s waterless, it must be all glycols, and how can that allowed? Evans is as slippery as other glycol/water-based coolants, but it will not form vapor, build pressure or boil out. Evans lower pressure significantly decreases the risk of coolant loss and is a much safer option that provides both performance and preservation advantages.
