- Brand SQV4 turbo blow off valve bov. Made of high grade CNC billet aluminum die-cast body and andized finished.Including oring,hardware.
- Our blow off valves is a dual stage pull-type relief valve. Unlike typical push type blow-off valves,will not leak under any level of boost.
- It is for maximum performance, incorporates both a small primary valve for ultra quick activation, and a larger secondary valve for additional discharge capacity. It is constructed of billet aluminum, which ensures long-term durability and a high luster look.
- Triple Fin design produces "Super Sound" .Triple Fins set at the center of the funnel produces a dynamic and aggressive sound. An optional special Round Fin can be purchased separately for sound tuning.
- Instruction is included. Professional installation is highly recommended!
- Item exactly the same as picture shown.
Model: SQV4 Blow Off Valve
Manufacturer Part Number: BOV1010
- Suitable for vehicles with turbochargers, other models without turbochargers installed with no effect.
- The so-called relief valve device is a device that prevents compressed air from running off the turbine in the opposite direction through the suction pipe when refueling stops. Failure to load and unload valves will cause damage to turbine blades. Smooth exhaust sound with strong impact charm, using a shiny aluminum alloy body, the most attractive engine room and durability coexist.
- All turbocharged engines produce this noise, but for everyday civilian vehicles, manufacturers design it as noise to reduce it as much as possible. This is done by releasing pressure into the intake manifold, so the noise is very low - this type of pressure relief is called internal discharge. When we step down the accelerator pedal to accelerate, the throttle opens, and the engine sends out "Hmm..." as the speed rises. Sound, the engine exhaust high temperature and high pressure exhaust energy to drive the exhaust turbine rotation, when the turbocharger work speed (that is, to make the turbine rotate more than 100,000 revolutions per minute), the turbocharger compresses the surrounding air, so that the engine intake increases, improve the engine power.
- When we collect oil, the throttle opening rapidly decreases until the idle state is closed.It is said that the engine does not need air intake, or the air flow in the intake pipe will be blocked at the throttle valve. But at this point, the turbocharger didn't stop working! Because of inertia, the turbocharger still keeps rotating at more than 100 thousand revolutions per minute. It is now conceivable that the air at this time continues to be continuously compressed into the intake pipe, if this part of the high-pressure air intake pipe can not be timely exhausted, it will make the intake pipe pressure rapidly increased, may cause throttle damage or intake pipe burst.
- At this point, it is necessary to install a pressure relief device in the intake pipe to unload the excess high-pressure air from the compressed intake turbine. Actually, the relief valve is installed on a valve on the intake pipe to control the booster pressure. The opening and closing of the relief valve is controlled by the electromagnetic coil operated by the ECU (electronic control unit). ECU will judge according to the turbine outlet boost pressure level, once the pressure exceeds the critical value, the solenoid coil will be electrified or power-off control, thereby opening or closing the relief valve. When the relief valve closes, it is based on ensuring sufficient intake pressure in the intake pipe. When the valve opens, it can release excess gas into the atmosphere, reduce the pressure in the intake port and protect the engine intake pipe. So we heard that the "bared and bared" sound on the refitted car was the sound of the relief valve during the pressure relief and exhaust.
- By adjusting the position of the heat sink, the pressure relief gas will hit the radiator at high speed because of different frequencies.Produce different pressure relief sound. But in fact, the pretend pressure relief valve will not improve the power of the car, basically it is just pleasant and interesting. Why the original SQV flameout is mainly a product design problem, may be relative to the electronic throttle, relief valve spring hardness caused by insufficient. SQV relief valve has the function of two pressure relief valves. It is decided to open the relief valve according to the angle of the throttle opening and closing. Because of the pull-line throttle used before the 8th generation, the throttle is straight-line, and the control of the inlet and outlet of the gas filtered from the relief valve is more direct; but later, because the 9th generation used the electronic throttle, by the company. In the process of retracting and discharging the throttle, the computer has a filter, and the turbine has a delay in entering and discharging, although very short, but enough to affect the pressure exerted on the springs inside the SQV.
