THE PREMIUM WATER PUMP BY ELTO RACING

The Italian company, already one of the leading manufacturers of kart exhausts and silencers, makes a leap forward even in the cooling systems market as well with its new premium water pump. Let’s get to know this high quality product, fully realized from a single piece, in detail.

The performance of 2T competition engines, such as those for karts, is strongly based on operating temperatures. These are largely governed by the water circuit, the shape of which is decisive in order to cool the hottest areas, such as the light side and the cylinder’s exhaust duct. In fact, cooling as much as possible is not enough: it is also necessary to do so in the correct way to obtain engine running temperatures that are ideal for both performance and reliability. Insufficient temperatures may, in fact, cause detonations in the combustion chamber, resulting in loss of performance or, in the worst cases, seizure. Similarly, even too low temperatures can result in performance drops, in this case due to the variation in the mixture’s vaporization phenomenon.

TEMPERATURES

On the other hand, as all karters know, the performance of the 2T racing engines strongly relates to operating temperatures. Therefore, the water circuit is fundamental. It should not be made with the aim of cooling "as much as possible" but rather to cool in the correct way so that the obtained temperatures are ideal for engine performance and reliability. In fact, both too hot temperatures (leading to combustion chamber detonations) and too low temperatures (resulting in a variation in the vaporization of the mixture) result in lower performance and, in the worst case, seizures.
