Again, another parts development directly from Evolution Racewerks' 135i Time Attack racing program.  The factory diverter valves were causing an issue of not being able to hold up against the rigors of high boost application, therefore they needed to be replaced.  Thus attention was brought to the factory diverter valve pipe and the need to optimize for maximum performance on a race car facilitated the need for a new pipe to be built.  Often ignored, charged intake airflow characteristics greatly affect throttle response, turbo lag and ultimately maximum power potential.  Smooth bends and minimal obstructions are ideal.  This is not the case with the factory diverter valve pipe.  On the factory diverter valve pipe features a sound baffle for the diverter valves.  This sound baffle is connected on the side of the factory diverter valve pipe which splits airflow.  This causes turbulence inside the pipe which slows the charge intake air velocity (speed of the air traveling inside the pipe).  By removing this turbulence (by eliminating the factory diverter valve sound baffle), increased throttle response, decrease turbo lag and ultimately higher maximum power potential can be realized.  Evolution Racewerks' Diverter Valve Pipe Upgrade eliminates this sound baffle and thus eliminating the unnecessary turbulence in the diverter valve pipe, keeping charge intake air velocity at it's maximum.  3" 6061 Aluminum piping was used to properly match the size of the throttle body as well.

Since one of the reasons for changing out the factory diverter valves was to prevent boost leaks (from prematurely opening on high boost), causing boost leaks while upgrading the diverter valve would be counterproductive.  The connection at the throttle body was looked over very carefully.  The factory diverter valve is connected to the throttle body using an o-ring inside the throttle body flange which is locked in place by a c-clip, which works very well.  It also make removal/installation quick and easy.  The throttle body lip is machined to accept this c-clip.  It is not designed for a silicone hose connection which is used by all the other brand diverter valve pipe upgrades in the market.  The throttle body lip is too short and there are no "beads" to prevent the silicone hose from blowing off under boost.  Even though it is the easiest way to  "rig" together, it is not ideal.  The best way to connect the new diverter valve pipe to the throttle body is to replicate the same connection.  Therefore, ER CNC machined their own replica throttle body flange that utilizes the same factory o-ring and c-clip for Evolution Racewerks' Diverter Valve Pipe Upgrade.

NOTE: Meth Bungs are now an available option on the Evolution Racewerks Diverter Pipe.

What are Meth Bungs?
A Meth Bung Hole are predrilled and threaded holes designed for the use of a meth kit.

The same issue came with the MAP sensor.  The MAP sensor seals to the factory diverter valve pipe via a o-ring on the sensor itself.  Having a hole in a silicone hose will definitely cause a boost leak as it will not properly seal.  Therefore, again ER CNC machined their own replica MAP sensor flange that utilizes the same factory o-ring seal.

The Diverter Valve Upgrade Pipe is available in the same 2 finish options as Evolution Racewerks' intercoolers.  It is available in a mirror polish finish.  It is also available in Evolution Racewerks' Type III Hard Black Anodizing for the guys that want the stealthy, factory look.  An added benefit of the Type III Hard Black Anodizing is that it hardens the aluminum piping and makes it more durable against accidental damage (like dropping the pipe).

Evolution Racewerks also offers their Diverter Valve Upgrade Pipe in any anodizing color of the rainbow you want (special order) and is available in only Type II Anodizing (aesthetics).  It is available as a special order item and is not stock. 

Brush (or plain) finish is also available.

Evolution Racewerks Chargepipes for 2010-13 BMW Z4 [E89] N54 BM-ICP005

The standard option for Evolution Racewerks' Diverter Valve Upgrade Pipe is designed for either the factory diverter valves or aftermarket "factory style" diverter valve.

ER can also build their Diverter Valve Upgrade Pipe to utilize any BOV or diverter valve you desire.  Love the way the HKS BOV sounds?  No problem, we can weld the HKS BOV flange on Evolution Racewerks' Diverter Valve Upgrade Pipe or any other flange type so that you can utilize any BOV or diverter valve you want.  Due to the fact that there are so many options for BOV's and diverter valves, it will be impossible for us to stock these options.  Therefore, it is available only as a special order and will be built to order.
