Can you put a BOV on a diesel?

Can you put a BOV on a diesel?

Normally the way a diesel engine functions means a Blow-Off Valve can’t be fitted in the same way as on a petrol. A Blow-Off Valve releases pressure built up between the throttle body and the turbo. A Diesel won’t generally have a throttle body, so this set-up won’t work.

What does a diverter valve spacer do?

The spacer is a pressure release system that can be used with the stock diverter valve to vent extra boost air into the atmosphere instead of sending it back into the engine’s intake piping.

Do diesels need a wastegate?

The wastegated turbo is great because it’s got a housing on the exhaust side that will spool that turbo up quick, but at the high rpm, when it’s spinning fast, it’s just too much for the compressor wheel. So, we need a wastegate to control the speed of the turbocharger.

What is a Audi diverter valve?

All stock Audi and Volkswagen vehicles come with a diverter valve rather than a blow off valve. The diverter valve is usually located on the side of the turbocharger, it is a pressure release system which diverts unused pressure back into the system preventing compressor surge.

Does a diverter valve spacer lose horsepower?

When you start putting in spring controlled DVs and spacers, what happens is the ECU can not accurately pulse/read the DV to create boost + load targets. This will inevitably cause power LOSS.

What happens when a diverter valve fails?

The valve is allowing some hot water through but not enough to make the water hot instead of warm. This is one of the most common signs that your diverter valve is faulty. It’s likely stuck on the ‘open’ setting to allow the radiators to stay warm instead of prioritising your taps.

What does a diesel wastegate do?

The wastegate is employed to control boost pressure via bypassing a controlled amount of exhaust gas from interacting with the turbine wheel. It consists of nothing more than a disk that closes against a passageway that redirects a portion of the exhaust flow.

What happens when diverter valve fails?

Among the most noticeable signs that the air diverter valve is damaged is your car running sluggishly. The air/fuel mixture of your car is very important in keeping it running smoothly. Having a bad air diverter valve will throw this mixture off and cause the car to run and idle rough.

Do all turbos have dump valves?

At the time, most factory turbo cars did not come with a factory blow-off valve. However, these early turbo cars were also running relatively low boost levels. Today, most modern turbocharged cars do have a blow off valve from the factory.
