dry sump oil system
- Sapa mau rubah mesinnya jadi dry sump ??
Bisa nambah horsepower yang lumayan tuh..
gw nggak lah, tanpa dry sump jalan 300k lebih tanpa turun mesin, lagian lebih
banyak didalam kota hehehehe...
Why do some engines use a dry sump oil system?
Most production cars have a wet sump oil system. The HowStuffWorks article on
car engines shows you where the sump is -- it's the area below the crank
shaft. In a wet sump, the oil that you put into the engine is stored beneath
the crankshaft in the oil pan. This pan has to be large and deep enough to
hold four to six quarts of oil -- think about two 3-liter bottles of soda and
you can see that this storage area is pretty big.
In a wet sump, the oil pump sucks oil from the bottom of the oil pan through a
tube, and then pumps it to the rest of the engine.
In a dry sump, extra oil is stored in a tank outside the engine rather than in
the oil pan. There are at least two oil pumps in a dry sump -- one pulls oil
from the sump and sends it to the tank, and the other takes oil from the tank
and sends it to lubricate the engine. The minimum amount of oil possible
remains in the engine.
Dry sump systems have several important advantages over wet sumps:
Because a dry sump does not need to have an oil pan big enough to hold the oil
under the engine, the main mass of the engine can be placed lower in the
vehicle. This helps lower the center of gravity and can also help
aerodynamics (by allowing a lower hoodline).
The oil capacity of a dry sump can be as big as you want. The tank holding the
oil can be placed anywhere on the vehicle.
In a wet sump, turning, braking and acceleration can cause the oil to pool on
one side of the engine. This sloshing can dip the crankshaft into the oil as
it turns or uncover the pump's pick-up tube.
Excess oil around the crankshaft in a wet sump can get on the shaft and cut
horsepower. Some people claim improvements of as much as 15 horsepower by
switching to a dry sump.
The disadvantage of the dry sump is the increased weight, complexity and cost
from the extra pump and the tank -- but that's a small price to pay for such
