The first 10 and the last 6 Taosha upgrade

In the car interviewed, the main modification projects are concentrated on the air intake and exhaust system. The owner of the air intake system chose the high-end Eventuri full carbon fiber air collecting box. This group of products was redesigned and used the space above the front bumper. The large-area BMC air filter is designed here, and the air inlet is directly extended to the top of the front of the water tank, so that the cold air poured into the air intake dam can be sucked into the turbine. Temperature helps tremendously. In addition, the volume of the air collecting box is maximized, and the size of the turbine air intake is increased by 85%, while ensuring that the airflow path does not contain sharp angles, so that the air flow rate is faster and smoother. The gas system can increase the horsepower of 15 to 25 hp.

For the exhaust pipe part, the same high-end Akrapovic titanium alloy exhaust pipe is selected. The brand has a ringing name from large heavy-duty motorcycles to supercars. Through the lightweight effect of titanium alloy material, the weight of the bottom of the car can be greatly reduced. At the same time, it emits a special sound that only titanium alloy exhaust pipes have, and this group of exhaust pipes also retains the original exhaust valve design of RS6. Except for the left and right valves on the tail exhaust pipe, the middle section of the original factory is retained. The valve at the X pipe is also reproduced on the Akrapovic titanium alloy exhaust pipe, which is of great help in balancing the exhaust pressure in the left and right pipelines at high speeds, making the engine run more smoothly, and the exhaust efficiency can also be effectively exerted.

For the chassis part, the original RS6 is equipped with a very special advanced sports car-like suspension, as well as Dynamic Driving Control (DRC), which has three-stage electronically adjustable damping, but the way it adjusts the soft and hard damping is different from the Commonly, the principle of rotating the valve in the cylinder core is different. Instead, the four sets of shock absorber cylinders are connected through diagonal oil pipes, and the damping oil volume on the inner and outer sides can be adjusted during steering to provide more support and reduce roll and Back and forth shaking situation. Also because this set of original shock absorbers can already provide excellent chassis control effect, the car owner did not replace the original shock absorbers, but only replaced the KW height adjustable short springs to moderately reduce the car height. , for a lower center of gravity and visual effects.

For the braking part, this RS6 did not purchase carbon fiber discs when purchased, so I entrusted Tuner to assist in replacing the front and rear brake discs with CCB carbon fiber discs, and replaced the original dual-piston calipers on the rear wheels with opposing four-point calipers. Piston calipers and electronic handbrake auxiliary calipers are added, so that the braking force can get the most obvious effect. As for the bead setting, which has a great influence on the appearance, the rim is made of American Brixton Forged CM5-R 22-inch double-piece forged aluminum rim, with black coating and angular claw design. It can be said to complement each other on this RS6.
