bir açıklama buldum biraz okudum ama tercüme ile uğraşamadım baş ağrısı felaket şu an

There are two major divisions in engine oiling systems: wet and dry sump. "Sump" simply means the chamber in the bottom of any engine that collects lubricants for redistribution. In a piston engine the oil pan is the sump. A wet-sump system is the same used in passenger cars and mostly seen in the lower levels of racing. Wet sump means engine oil is collected and stored in the oil pan until it is recirculated by the oil pump back through the engine. In a dry-sump system oil is collected in the oil pan and immediately sucked, or "scavenged," to an external tank before being recirculated to the engine. Because the sump is not used to store oil, it is referred to as "dry."

A dry-sump system has several advantages over wet, but the main one is additional power. Because there is only a minimum of oil in the pan, windage—oil clinging to or splashing against the rotating assemblies of the engine—is greatly reduced. In addition to evacuating oil from the pan, the external oil pump creates a vacuum inside the pan and block that further increases horsepower by improving ring seal. Other advantages of a dry-sump system are increased oil capacity because of the external tank, the ability to easily add remote oil coolers, and because the pan doesn’t store oil, it can be quite shallow to allow for lower engine placement.

A wet-sump system is simple, low cost, and light weight. That's why virtually every production engine in the world uses wet-sump lubrication. A dry-sump system is more complicated, more expensive, and heavier, but it offers continuous lubrication under all conditions and the promise of increased power through reduced windage.

When you consider cost and complexity, a wet-sump oil system is the logical choice for most Sportsman racers. The biggest mistake a Sportsman racer can make, however, is to try to duplicate the performance characteristics of a dry-sump using a wet-sump system. This can't be done without sacrificing reliability.

Alp anlamışsındır umarım :) Yapmak istiyorsan ayrıca görüşebiliriz tabii ki :D genelde performans arabaları dry sumpa çevriliyo, nedense türkiyede pek yapılmıyor :)

Kuru Yağlama sistemi (Dry sump), bol beygirli motorlarda tercih edilir, ani hızlanmada karterde yağın duvara sıvanması, zeminde kalamaması, soğutmanın daha daha iyi olması gibi avantajları yaınıda, fiziksel imalat zorunluluğu da olabilir, kartersiz bir motor daha aşağı konumlandırılır, 15-20 cm e kadar aşağı alınacak böylesine bütük kütle, yol tutuşa ciddi avantajlar sağlar. Fabrikasyon bir sistemdir, sonradan dönüştürelemez, teorik olarak dönüştürülür ama saçma olur.
