Amsoil Dominator® Coolant Boost
Racers demand lower engine operating temperatures to achieve maximum efficiency and horsepower on the track. Many racers use straight water as a coolant, which invites damaging radiator and water-pump corrosion. AMSOIL DOMINATOR®Coolant Boost (RDCB) provides racers and motorists with significantly lower engine operating temperatures, quicker warm-up times and advanced corrosion protection.
DOMINATOR Coolant Boost is formulated with proprietary tiered-surfactant technology, providing quick and effective heat transfer inside radiators and cylinder heads and resulting in reduced operating temperatures, more efficient operation, increased horsepower and significantly reduced engine warm-up times in cold weather and before a race. Coolant Boost also contains a robust mixture of corrosion inhibitors that protect the radiator, heater core, water pump, cylinder heads, engine block and intake manifold from the damaging effects of corrosion.
Engine Warm-up Reduction Test To test DOMINATOR Coolant Boost's ability to reduce engine warm-up times, the product was added to an antifreeze/water mixture in a V-8 test engine. The engine was run at idle until it reached a prescribed temperature of either 120°F or 180°F. Ambient temperature was maintained at 30°F to simulate winter conditions.

Temperature Reduction Dynamometer Test To test temperature-reduction capabilities, controlled engine dynamometer (dyno) tests were performed on a 350 cubic inch Chevy* engine with an aluminum block and cylinder heads. In each phase of testing, the engine was operated at 4,500 rpm until coolant temperature stabilized. As benchmarks for the test, straight water stabilized at 220°F and a 50/50 antifreeze/water mixture stabilized at 228°F.

Cast Aluminum Alloys Corrosion Test The Cast Aluminum Alloys Corrosion Test (ASTM D4340) measures corrosion protection properties in modern automobile and high-performance race engines with aluminum cylinder heads. A cast aluminum puck was heated to 275°F at 28 PSI and exposed to the test coolant mixture for one week. Weight loss of less than 1.0 mg is required to pass the test.
