January 28th, 2012 admin

The Porsche 911 GT3 is a high performance version of the Porsche 911 sports car. It is the latest in a long line of high-performance models, which began with the 1973 911 RS.

Porsche 911 GT3 Engine and Transmission

The engine of the Porsche 911 GT3 sets it apart from most other 996 models, although the same basic 3.6-liter engine capacity of 996 standard type called “integrated dry sump lubrication” six-cylinder engine shares. Together with those of the Turbo and GT2, it’s actually on the original air-cooled 911 versatile, true dry-sump lubrication based crankcase, an external tank. The original version of the GT3 had 360 hp (265 kW, 355 HP), compared to 300 hp (221 kW, 296 HP) of the 996th regular.

 

In Porsche 911 GT3 configuration, this so-called “split” crankcase (ie the line of the crank to the crankshaft centerline) is used instead of a fan and finned cylinders, separate water jackets on each side of the engine with the banks in the three However cylinders cool with water, pumped to a radiator. Thus, the GT3 engine is very similar to the completely water cooled 962 racing car engine, which is also based on this same crankcase. The 962 is different than using 6 individual cylinder heads while GT1/GT3 how air and water cooled Porsche 959, uses 2 cylinder heads, each of a bank of three cylinders. The GT3 engine could thus be considered similar to a 959 engine, but with water-cooled cylinder.

 

In early 2004 model Porsche 911 GT3 production, the base was casting for the crankcase of the GT3 uses exactly the same as the air-cooled engine and was the “964″ casting number on the bottom of the sump and areas worked normally in the light of air-cooled application not be processed for use in water-cooled application. The crankcase casting was changed in mid-2004 a “996″ casting number on this remote air-cooled engine with residues removed, but internally the same.

 

This engine gives the Porsche 911 GT3 a distinct racing sports heritage dating back to the Porsche 904 / 6 from the mid-60′s, the Porsche Carrera Cup and 997 Super Cup and RSR racing cars of today.
Because the 911 air-cooled engine uses the 356 engine transmission mounting flange configuration, the GT3 is a manual used by air-cooled 911 heritage. This gearbox has interchangeable gear ratios and is more durable making it suitable for racing than the standard Porsche 911 type 996 gearbox.
At 450 hp (336 kW), the 3.8-liter six-cylinder engine in the 997 GT3 RS is the most powerful production six-cylinder engine in a car with a 118 hp (88 kW) per liter.

Porsche 911 GT3 1999

Due to the lack of official Porsche team in the 1999 24 Hours of Le Mans, the only hijacker nearly 993 old air-cooled turbo GT2 is expected to represent the brand had a few chances for the Chrysler Viper GTS-class honors beat.

In 2007, Porsche installed before the air fins, the channel air into the radiator and out through the bonnet. This helps in the treatment of the car, just once in the GT3 RSR is followed by another car, the indiscriminate use immediately denied and the car will be considerable understeer in the front wheels experience by all the weight on the back of the car-oriented. For 2011, Porsche splitter on the front and increased the tire with a diameter of understeer problem to overcome. So far, the GT3 RSR is the most successful GT car hit.
