This EPMAN Diesel Funnel Dump Valve Kit is a versatile solution for turbo diesel engines, specifically engineered to eliminate compressor surge and reduce back pressure created during gear shifts or deceleration. When the throttle is closed, excessive pressure builds up, causing turbo cavitation. The funnel dump valve provides sufficient airflow to release this pressure quickly, improving boost response between gear changes and reducing turbo wear.
Key Features:
- Material: Aluminum
- Color Options: Black, Blue, Silver
- Weight: 1.2 kg
- Universal Fit: Suitable for any turbo diesel engine, such as VW Transporter T4 T5, BMW E36 E39 E46, Ford Fiesta and Focus TDCi/TDI models
- Installation Requirements: Some vehicles may require a T-piece connector
Package Includes:
- 1x diesel funnel dump valve
- Necessary installation parts
Important Information: Professional installation is highly recommended. Pictures are for illustration purposes only.
This kit is perfect for those looking to enhance their turbo diesel vehicle’s performance and increase the durability of their turbo.
Important:
The product must be installed exclusively by a qualified professional. In case of self-installation, the warranty will be void, and the manufacturer takes no responsibility for any resulting damages.
1. Power Supply Connection:
- The controller requires a 12V DC power supply.
- Connect the red wire to the positive ignition power line, secured with a 10-amp fuse.
- Attach the black wire to the vehicle's ground point or the negative terminal of the battery.
2. Accelerator Pedal Signal Connection:
- The controller's yellow wire monitors the accelerator pedal signal, which is the 5V wire from the electronic accelerator pedal.
- You can identify this wire using a voltmeter: with the pedal pressed, it shows approximately 5V, and when released, it measures close to 0V.
- To find the correct connection point, check near the engine control unit (ECU) wiring harness or directly at the accelerator pedal connector.
3. Solenoid Connection:
- Use two of the solenoid's vacuum ports: one for the vacuum source and one for the blow-off valve. The third port must be left open to atmospheric air.
- If the third connection is not correctly vented, the valve may remain open, causing operational issues.
4. Timing Adjustment:
- Open the control box to access the potentiometer, which allows you to adjust the valve's opening duration between 0.1 and 1.5 seconds.
- The red LED indicator near the potentiometer confirms proper operation of the controller.
5. General Installation Tips:
- Ensure the required vacuum for the solenoid is sourced from the intake manifold pressure line.
- If the blow-off valve spring preload is too strong or the vacuum pump is insufficient, consider using an additional vacuum reservoir.
- Carefully check all electrical connections during installation to avoid damage to the ECU.
With this system, you can not only reduce turbo backflow, but also enhance your vehicle's unique sound experience!
