Last, but not least, if engine temperatures are above optimum, then you will loose horsepower, and you will shorten the life of the engine
Fortunately, water has a tremendous capacity for absorbing and carrying away heat. For every degree in temperature rise, water can absorb five times as much heat as aluminum. Ethylene glycol, the main ingredient in most cooling system additives, has about a 25% lower heat capacity than pure water. That’s one reason why a cooling system be filled with straight undiluted additive increases the risk of overheating. Don’t forget however, that Glycol raises the boiling temperature of the coolant when mixed with water, and is effective in preventing corrosion and freezing – in other words, unless you are on the ragged edge of performance, and are fanatical about maintenance (you will be changing the pump frequently!!) use cooling system additive in the correct proportions to a fraction lean.
HyperFlow has utilized a number of tools on many; many test sessions on bikes from 65cc to 650cc to assure the product performs. A combination of dynamic flow testing of the system, digital thermometers on back to back track sessions, and multipoint data logging, engine dyno, and now CFD analysis are used to optimize performance.
