Blow Off Valve (Dump Valve )

Thanks bud. Could you guide me in the right direction to how to fit one please

This is ridiculous on so many levels.

 

A dump valve opens to dump boost pressure when the throttle plate is closed to stop turbo stall and works by relieving the transient overpressure.

 

However, diesels dont have throttle plates, only petrol engines do.

 

So if you fit one and somehow get it working,  you will look and sound ridiculous as you try to accelerate (if thats the correct word to use..) your 2 tonnes from 0 - 60 in a hair raising 20 seconds. and when your device farts, you'll lose all your boost pressure, power will drop close to zero, and the ecu will trip limp home mode.

 

Even if you remap the ecu and somehow bypass the ecu safetys, you will still lose all power every time it farts.
