Ford Focus Diesel Blow-off

The sound is taken with a camera that does not offer very good sound recordings and in reality the sound is louder ... The car was standing still which means that the turbo charger is not under load! During driving when the turbo charger is under load the produced sound is much more louder.

The BOV can be installed on almost every car with a turbo diesel engine.

does it improve performance?

[zolll1]

I didn't measure the exact acceleration of the car with the BOV or by turning it off so I can't tell you for sure whether performance is affacted. In the worst case performance should remain the same.

The blow-off is fitted directly to the turbo's system. It has electrical control unit together with a senzor mounted on the gas pedal (not clutch!). It works really well, I have it on my car since 3 years.

It's with the standard turbo charger.

@yonutz4 does it fuck

[ratpie]

diesel engines dont need a BoV, since there is not throttle plate.

[totalguy]

waste of money dump valves on diesels like this

@ketkiddy

they probably are pointless on a standard turbo/boost.

[ketkiddy]

@tpvalley your obviously more knowladgeable about engines than me, i dont know nowt to be honest, all i know is on forum i used to go on when i had my golf Gt Tdi 140 golf, all the tuners who used to go on said they do absolutely nothing for tdi engines and are a complete and utter waste of money, thats all i was going off. everybody's entitled to their opinion, not sure who's right or wrong, all i'm saying is, i'll never put one on my car :o)

@ketkiddy

obviously they are to stop compressor stall when butterfly is closed but they also reduce lag.

even on a diesel when u let of the accelerator u get low pressure driving turbine yet still highish pressure in the intake/compressor and this slows the turbo, a BOV prevents this by unloading the compressor.

Have u never witnessed compressor surge in a diesel? u do get it, especially as diesels boost much higher than petrols- these are about 15psi standard, I ran mine at 25psi!

[ketkiddy]

Blow off vavles, dump valves or whatever you wanna call them do absolutely no good on turbo diesel engines, you may aswell just take a shit in your fuel tank
