The Mercedes W205 C63S AMG intake system is the culmination of extensive development and testing. Our design brief consisted of 3 main objectives: 1) Increased flow rate. 2) Low intake temperatures. 3) Smooth airflow. The first objective was met by utilising all of the limited space available in the C63S engine bay resulting in a 35% higher flow rate over the stock system. The second objective was met by designing a fully sealed system. The C63S engine bay reaches high temperatures with heat sources like the turbos in close proximity to the intake so it is crucial that the intake remains sealed. The final objective was met by designing an organically shaped system with custom rounded panel filters to ensure the airflow path contained no sharp corners and therefore allowed for the flow to remain laminar. With smooth transitions from the filters to the turbo inlets, our intake minimises the formation of turbulence and therefore the turbos are able to operate more efficiently.
With all 3 objectives met, our W205 C63S intake system delivers on all fronts and allows for the turbos to generate boost more efficiently. This results in an improved throttle response and genuine power gains which increase with higher states of tune. Since there are various turbo upgrades available for the C63S we have also catered a specific solution for larger turbos. Our C63S intake is available in 2 configurations: 61mm ID outlets to match the stock turbos and 76.5mm ID outlets to match larger turbos.
Dyno tests were carried out on both a fully stock C63S and a stage 2 C63S which had downpipes and a remap. Below is the dyno graph for the stage 2 car which had the same tune on all runs and only the airbox was changed. Importantly the hood was closed for all runs to simulate road conditions. Dyno testing with the hood open - especially with open cone style intakes does not give a reliable indication of how the intakes are affecting power. On the road the hood is closed and so all the heat from the turbos is trapped in the engine bay. On the C63S this is intense heat which is why a sealed system is so crucial. Dyno testing an open cone system with the hood open will yield gains but once on the road the heat soak will cause a significant detriment to the power with the open cones sucking in the hot air. With higher air temperature being less dense, the turbos will not make as much boost resulting in lower power.
Here it can be seen with our fully sealed system that the power increases linearly after 4800rpm where the airflow demand increases and the stock airboxes become a restriction. These performance gains were measured after only changing the stock airbox for the Eventuri intake - all other modifications were present for both the stock airbox and the Eventuri intake.
The gains measured on the dyno translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency. The car was tested firstly with the stock intake - hood closed. We then left the car on the dyno and installed the Eventuri. The car was then run again - hood closed. Several runs were carried out with both configurations to get a consistent result.
The Eventuri C63S AMG intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
2 x Carbon Fiber Airbox Lids with Turbo Inlet Transitions
2 x Carbon Fiber Airbox Bases with Inlet Duct Transitions
2 x Bespoke High Flow Panel Filters
4 x CNC Machined Aluminium Filter Flanges
2 x CNC Machined MAP Bosses
4 x CNC Machined Rubber Mount Holders
2 x Custom EPDM Ducts with Reinforced Internal Frames
Laser Cut Stainless Steel Bracket Work
AIRBOX ASSEMBLIES
The airbox assemblies consist of the upper and lower sections which are separated by the filter panels. Each section has been meticulously designed for maximum internal volume whilst ensuring a smooth path for airflow to travel to the turbos. The most challenging aspect of this design was to increase the internal volume of the airboxes in an attempt to increase the flow rate capacity over the stock airboxes. Since the C63S engine bay is so tightly packed, this was only achievable by maximising the total internal height of the airboxes. The biggest increase came from enlarging the upper airbox lids. As can be clearly seen, we have managed to achieve a significant increase in volume while also providing a smoother airflow path.
SIDE PROFILE
Looking at the side profile comparison between the stock and the Eventuri airboxes, it is clear that the stock airbox has a restricted space for airflow after the filter in the upper section. It narrows down to just 23mm in height whereas in comparison, the Eventuri system achieves a height of 56mm which is 143% larger than stock. The stock airbox also has a large area on the top section which is taken up by the MAP sensor. This area is taken away from the internal volume and therefore causes another restriction. We have relocated the sensors to the back of the upper sections allowing the full volume above the filters to be useable for airflow. Another consideration is the inlet to the lower airbox which on the stock system has a flexible convoluted section with multiple ridges at 43mm in height. Our system removes these ridges for a smoother entry and increases the height to 74mm.
FRONT PROFILE
The front view of the airboxes clearly show how restricted the stock version is. With the upper section narrowing down to just 23mm across a large section, airflow is significantly restricted. In comparison our airbox maintains a much larger area to the turbo inlets. The inlet to the lower section has also been significantly increased in area. The Eventuri inlet is approximately 84% larger in cross sectional area compared to stock.
BESPOKE PANEL FILTERS
To achieve optimum airflow we designed custom panel filters which have a double filtration layer of ISO 5011 tested non-woven mesh. The filtration medium is dry so does not require oil which can harm sensitive flow sensors. In addition, we designed them to have a rounded outer profile rather than the traditional rectangular shape which has sharp 90 degree corners. This allowed us to maintain a smoother airbox profile which has no sharp corners thus minimising the onset of turbulence in the flow path.
Looking into the lower airboxes, the difference between the square and rounded corners is clearly visible.
CNC MACHINED FILTER FLANGES
A crucial consideration when using panel filters is to ensure that they are properly sealed inside the airboxes at all times. Since we are using prepreg carbon fiber for the airboxes, we could not rely on the relatively large tolerance of carbon construction in comparison to a precision machined component. Therefore we designed flanges CNC machined from a single billet of aluminum and black anodised, which the filters sit inside. These flanges are mounted inside the carbon airboxes and provide a reliable and accurate seal around the rubber profile of the filters.
EPDM FRONT DUCTS
The final components are our custom made EPDM ducts which connect the airboxes to the front of the engine bay and provide the flexibility required during engine movements. During development we also considered the vacuum forces from bigger turbos and therefore to prevent the EPDM ducts from sucking themselves closed we added a fibreglass reinforcing frame to the middle section of the inside of each duct. These frames provide rigidity while still allowing the ducts to give the assembly the required flexibility.
CNC MACHINED MOUNT HOLDERS
To hold the airboxes in place we use the stock rubber bushes and to hold these bushes we have CNC machined the holders for an exact and secure fitment.
Every aspect of the design was considered in great detail and the end result is a system which sets a new benchmark for intake design on the Mercedes C63S AMG.
