HyperKuhl High Performance SuperCoolant

Recommended for highly tuned engines

Heat-transfer limitations of antifreeze can cause overheating and detonation. This is especially the case with high compression racing engines. Inadequate transfer of heat away from engine cylinder heads can cause detonation and engine damage. This requires ignition timing to be retarded, resulting in loss of horsepower and performance

Modern engines run hotter than ever. Smaller displacement engines, forced induction, and increased compression ratios, the demands of engine coolant are higher now than ever.

Straight water conducts 140% more heat than glycol, and 60% more heat than a 50/50 mix. Therefore, running a standard 50/50 mix could be causing overheating and detonation in your engine. But using straight water also presents serious problems, because water coolant does not provide any corrosion protection.

HyperKuhl High Performance Super Coolant reduces the surface tension of coolant, allowing it to make better and more direct contact with metal surfaces inside engine cylinder heads. This effectively allows coolant to absorb more heat from the engine, and drain it to the external environment via the radiator. This results in a net increase in heat transfer, and net reduction in stabilized coolant temperature, as depicted in the graph above.
As also depicted in the graph, HyperKuhl provides optimal temperature reduction performance when used in straight water coolant. Temperature reduction of twenty degrees or more can be achieved by using HyperKuhl in straight water coolant. The reduction in cylinder head temperature allows ignition timing to be safely advanced without the threat of detonation, increasing horsepower. It also reduces the octane requirement of fuel, allowing lower octane fuel to be used without the corresponding risk of detonation.
Perhaps most importantly, HyperKuhl provides 100% protection from corrosion and electrolysis, even in straight water coolant. It contains the most advanced inhibitor package of any super coolant additive on the market today, and provides complete protection for all metals in a cooling system - particularly aluminum.


When used in a 50/50 mix, add 1 ounce of HyperKuhl per quart of coolant. When used in straight water coolant, add 1.5 ounces of HyperKuhl per quart of coolant. Because water transfers almost 50% more heat than glycol, best results will be achieved by using as little glycol in coolant as possible. For straight water coolant, reverse osmosis (RO) water is recommended. Most bottled drinking water consists of RO water. Do not use distilled water unless mixed with 50% antifreeze. Add HyperKuhl once per year or 30,000 miles, whichever comes first. After 5th year, drain, clean/prime cooling system with HyperKuhl Flush, and refill. Neglected cooling systems that are heavily contaminated should be flushed with HyperKuhl Flush prior to treatment.
