Blow Off Valve For Turbo

Mugen_Power · 11th June 2006, 14:04

Guys,

I want to know what is Turbo Blow Off Valve?
How Does It Work ?
Can anyone please provide the picture of it ? Can it be fitted in Skoda/Merc?

I have heard, hissing sound of turbo is awesome,
and it comes from Blow Off valve, Is that TRUE?

Experts So Please Help Me Out..

Cheers,
Mugen_Power.

The blow off valve is basically a diverter valve the only difference being that the Blow off valve exits the excess air into the atmosphere whereas the Diverter valve diverts the air back into the intake system.

Since you are looking for sound the bad news is you cannot fix a blow off valve on a Skoda or a Merc. The ECU will see it as a fault and will show up a CEL( Check Engine Light). The closest option for you is to use an aftermarket Diverter Valve like the Forge ones but again they can be used only for the Skoda Petrol 1.8T's. HOPE THIS HELPS

An RS uses a Diverter Valve and cannot be fitted with a BOV as both work in the same way but divert the excess air in seperate areas.
I think its a Japanese "thing" to use BOVs and an European "thing" to use a Diverter Valve.

Ive seen and heard a couple of skodas with bovs in Bangy.It should be possible.

All OEM installations (regardless of country of origin) use diverter valves (or compressor bypass valves) because BOV's dont make much technical sense. Its only for the noise. You get much better spool between shifts with a diverter than a BOV.

What is the added benefit of Diverters . How much will it cost?

Peter Sir , Can you please let me know about the cost of the aftermarket Diverter Valve you mentioned here , for my Skoda vRS ?

I think the correct technical thing is Compressor By Pass valve. It simply releaves the excess boost pressure than what is required by the engine. And In a way is required in every installation. Has any body heard of Turbocharger surging? This device reduces the opportunity of Turbo Surge.
