Newer models have a bypass valve to lower parasitic power lose during cruising.
The bypass valve is a release which vents off pressure in a rapid de-acceleration situation. When the supercharger is producing boost and you abruptly let off the gas, closing the throttle plates, the boost has nowhere to go.
The ERG valve is a valve in the turbo/supercharger system that controls boost pressures to the manifold. Normally it is hooked up to the computer system and the throttle body. Sometimes just the throttle body.
Is te oil leaking from the turbo into the exhaust, or is it that the oil is leaking from the exhayst into the supercharger? I have a 2004 Jetta that is leaking oil from the exhaust port into the supercharger. I think that the culprit is either a bad valve guide, or exhaust valve oil seal. Write me back and let me know what you find.
NO. deffinatly not. you need to have a turbo on you car! wow what a ricer
A supercharger is constantly spoiled from pulleys even at idle. This additional air pressure must be released at idle to prevent excess idle surge. The air release typically is performed through a bypass valve (can be replaced with blow off valve) and the air escaping tends to create a whistle. The remaing air sounds from pressure release in between shift points are identical to the process/sounds in which a turbo releases excess air pressure. However, a turbo is exhaust driven and the excess surge in pressure does not occur at idle which is why they are much quieter when sitting still.

evap vacuum cut valve bypass valve
Yes, a Blow Off Valve can function on a supercharger. Basically a BOV is a surge valve. It prevents the excess air from going back into the supercharger once the throttle body closes. Most superchargers will come with a by pass valve which is almost identical to a BOV. They both are used to vent the excess air out of the discharge tube so you do not get compressor surge. They are not 'basically' the same... they function differently. You should NEVER use a BLOW off Valve on any supercharger, only use a surge valve. There is a difference, look it up. One is normally closed except when there is vacuum on the manifold at which point its open. Blow off valves will slowly damage any centrifugal and should only be used on a turbo system.... Call procharger if you like. Terms are usually mis-used... simiar purpose but different approach. /////////////////////////////////////////////////////////////////////////////////////////////// You CAN use a blow off valve on a supercharger. Its all in how your system is set up to handle a BOV and how your BOV is set up(spring pressure) to handle the supercharger. Procharger was the place that told me to switch to a Blow off valve.
can you install it yes. will it benefit you on a non turbocharged or supercharged car? No. A BOV vents any pressure above atmospheric pressure (the increased pressure fed buy a turbo or supercharger ie boost) when the throttle body closes in order to keep the air from flowing back to the turbo or supercharger and potentially damaging it. in a NA (naturally aspirated) engine there is no increase in pressure above atmosphere.
No, without a turbo, there is no blow off valve. However, if you really wanted to, they have fake blow off valves for sale. These mimic the sound of a blow off valve. It would be an absolute waste of money, but hey, it's your money.
The sound you hear is likely the blow-off valve releasing excess pressure from the turbocharger when you release the throttle. It is a normal operation and helps protect the turbocharger from damage. If the sound is extremely loud or unusual, it might be worth having your turbo system checked by a professional.
There is no button for the supercharger. The supercharger is always on because it is being driven by the belts of the engine. When you step on the gas, there is a vacuum line that is hooked up to the supercharger in which will close a little valve causing the boost to be diverted into the engine.
