Because turtles 110 degrees N54 Original oil began to enter the large loop in the Taiwan hot climates hardly trial, so the letter of spades is the use of these special items will note a small turtle oil circulation system inside the factory sealed, exhaust manifolds using a large loop to enhance the cooling efficiency, an additional oil cooler with dual, high oil temperature operation can be still maintained at less than 110 degrees, for the protection of the oil film has a very positive effect.

HPI fuel injection timing of the piston-cylinder direct injection near the top dead center instantly, so that oil and gas injection compression instant explosion, and therefore the use of a relatively small amount of oil relative to the cylinder head temperature is quite high, so the water spray mixed with industrial alcohol injection After, in addition to the use of alcohol ignition characteristics to improve low combustion efficiency, but also can significantly reduce the combustion temperature.

The original N54 mini quite cold, so no matter whether there is to do strenuous boost the value of the promotion, plus a large pre-cooler is absolutely necessary to replace. billet connecting rods

There are two ways to reduce the exhaust pressure, the first is to upgrade the turbine exhaust side AR value, the second is to try to pass-through of the exhaust system, so that the exhaust gas can quickly export, and will not fully accumulated in the turbine exhaust turtle, so the turbine temperature continued to rise.
