Racers demand lower engine operating temperatures in order 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.
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 120ºF or 180ºF. Ambient temperature was maintained at 30ºF to simulate winter conditions.

To test temperature-reduction capabilities, controlled engine dynamometer (dyno) tests were performed on a 350 cubic inch Chevy* engine with an aluminium block and cylinder heads. In each phase of testing, the engine was operated at 4,500 rpm until the 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.

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.

In the Corrosion Test in Glassware (ASTM D1384), six metal coupons constructed of the most common metals in automotive cooling systems were totally immersed in aerated coolant mixtures for 336 hours at 190˚F. Each test was performed three times to determine the average weight change for each metal. The ASTM sets the allowable weight loss maximums for each metal.

In the Simulated Service Corrosion Test (ASTM D2570), six metal coupons constructed of the most common metals in automotive cooling systems were exposed to ASTM corrosive water designed to simulate hard and corrosive water in degraded coolant for 1,064 hours at 190°F. Coolant was maintained at a temperature and flow rate equivalent to the operating conditions seen in most passenger vehicles. Corrosive weight loss suffered during the test determines the additive’s corrosion protection properties. The ASTM sets the allowable weight loss maximums for each metal.
