Porsche 911 GT2 RS – 3.8 l and the water injection

5 June 2017

On the Nurburgring during testing was seen the Porsche 911 GT2 RS 2018 model year

Until today there were only rumours, which are now confirmed – on the chassis of the 991.2 will appear extreme model of the Porsche 911 GT2 RS. Foreign media representatives were given a ride on the prototype GT2 RS with the package of improvements Weissach Pack on the famous track, dubbed "the Green Hell". While the boys skated and took pleasure in the head of the Porsche GT Division, spoke about the power plant "the king's rear-wheel drive."

The main theme was the story of the engine mounted on the chassis of the 991.2 for the GT2 RS. As it turned out, the model will use a 3.8-liter "boxer". So now we can forget about 4.0-litre twin-turbo for the GT2, which "runs in" Porsche GT3 2018 model year.

The described engine mounted on the Turbo S produces 580 HP and 750 Nm. The motors are equipped with a special "anti-lag" system, which allows to significantly reduce the time of failure ("turbo-hole") when the driver removes his foot from the accelerator pedal, for example, when shifting. For the Porsche 911 GT2 RS this engine will boost to 650 HP and will be equipped with water injection system into the intake manifold. This technology is already used on the BMW M4 GTS.

The idea itself is not new and came from the distant past. The essence of the process is that the intake manifold is injected a small amount of water, which evaporates, cools the fuel air. Of course in physics for grade 7 we know that the lower the temperature of the gas, so it is denser. Therefore, the degree of filling of the cylinders of the engine with a similar system will be higher and with it the completeness of combustion and power plant as a whole. In addition, dramatically reduced risk of detonation, and this is the way to increase the compression ratio and again, the possibility of increasing the power of the internal combustion engine.

As to the mass of the Porsche 911 GT2 RS, the engineers have worked very well. Is considered normal if the automaker is releasing a "hardcore" version of the model reduces its weight relative to the "donor" at least 100 kg. So the GT2 RS shows when weighing 1500 kg 1675 kg Turbo S.

Previously rumored, Porsche 911 GT2 RS been round the "Green Hell" in 7:05. At this time, the media representatives stated that they were able to pass this track is exactly 7 minutes. At the moment everything is on the level of stories – let's see what the numbers will be after the release of the production model. By the way, as in the case with the Porsche 918 Spyder, 911 GT2 RS can be ordered with package Weissach package through which the product can lose weight by another 30 kg.
