Description

Eventuri BMW Carbon Chargepipes

Info

Introducing our Raw Carbon Fiber S55 Chargepipes. We have invested months of intense R&D in development and testing to bring you OEM replacement chargepipes which leave no room for compromise. FITMENT- FLOW QUALITY STRENGTH are the 3 main design criteria which we sought to meet.

1) FITMENT : A common issue with aftermarket chargepipes is the poor fitment due to the nature in which they are made using bent metal tubes. Clearances with the engine cover and other aftermarket intake systems can be an issue. Our solution with using carbon fiber allows us to use complex geometry in order to provide and OEM-like fitment whilst retaining optimum flow.

2) FLOW QUALITY : Our design uses smooth curve transitions from the turbo outlets to the charge-cooler. In addition we also increased the internal volume as compared to the OEM version to allow the turbos to work with less restriction. Importantly our machined flange attachment to the turbo outlet maintains a constant diameter to the chargepipes without and exposed edges which could cause turbulence. This is an improvement over aftermarket metal chargepipes which often have welds between the flange and the tubes.

3) STRENGTH : The final criteria was to increase the structural strength of the chargepipes over the OEM versions. It is becoming increasingly common for the OEM chargepipes to fail especially with tuned cars running higher boost levels. By using a cross-directional carbon weave layup with multiple layers to form a 2mm wall thickness, our chargepipes provide an incredibly strong solution for reliable operation even with larger turbos. Furthermore we have embedded CNC machined stainless steel rings into the openings where the clamps are tightened to ensure the pipes maintain their shape even under high clamping forces.

In order to increase the structural reliability of the carbon chargepipes we have not added methanol ports into them. Instead we are developing a separate J-pipe which will incorporate multiple methanol ports. Having these ports in the J-pipe is also a more suitable location for additional cooling since it is immediately before the inlet manifold.

Product Details

The Eventuri S55 Carbon Chargepipes are manufactured from high temperature prepreg carbon fiber and come with a number of other components engineered to perform a specific purpose and fabricated to the highest of standards.

Each intake system consists of:

• 2 x High Temperature Carbon Chargepipes
• 2 x CNC Machined Turbo Flanges
• Silicon Couplers With Oil Resistant Lining
• Marine Grade Stainless Steel Hose Clamps

Carbon Fiber Chargepipes

Our chargepipes are fabricated from high temperature prepreg carbon fiber. The construction utilizes multiple carbon layers which are applied with cross directional weave patterns to increase the strength of the part. Each pipe has machined stainless steel rings embedded in the openings to provide extra strength in the clamping areas. The pipes have smooth bends and reliefs to provide an efficient flow path for the pressurized air to negotiate from the turbos to the cooler. By ensuring there are no sharp corners and exposed faces, the turbos are able to operate as they were designed with the OEM chargepipes.

CNC Machined Turbo Flanges

The connection to the turbo outlets is done by using CNC machined flanges which use the OEM O-ring to provide the required seal. Each flange is machined from aircraft grade Aluminum and then black anodized. High quality silicon couplers are then used to mate the flanges to the pipes and constant tension marine grade clamps are then used to make them secure.

Performance

Dyno Testing

Below is a dyno graph showing the comparison between the Eventuri and the stock airboxes on a standard F80 M4. As you can see, power and torque are increased through a large portion of the rpm range not just at the peak. This 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. Since dyno results vary between consecutive runs, this graph shows the highest power figure achieved with the stock setup vs the highest figure with the Eventuri.

Since the F80 M4 is sensitive to heat soak, dyno figures can vary between runs – we could have shown the highest figure achieved with the Eventuri VS the lowest achieved with the stock setup, however this would not be a fair comparison. Just to illustrate the variation, here is the graph showing highest Eventuri VS lowest stock which was recorded on the day showing a gain of over 31hp!
