However, this isn’t such a bad trade off for an improvement in driveability and performance. In testing, the Turbine Diverter Valve has shown the ability to get larger turbochargers to spool much quicker. In fact, there is a substantial increase in torque and a moderate increase of horsepower between 1,800 rpms and 2,500 rpms.

What does a diverter valve do?
The diverter valve is a pressure release system, that "diverts" un-used pressure back into the system. Like when you let off the gas, or in between shifts.
Should you replace the stock diverter valve with an aftermarket option?
There are two big incentives as to why you might want to replace the stock diverter valve with an aftermarket option. One, the stock diverter valve uses weaker plastic and rubber parts that are prone to failure due to high operating temperature. The other motive is to raise the performance ceiling.
Why go fast bits Diverter Valves?
The stock diverter valve’s spring is typically too weak to withstand increased system pressure, causing boost leak. Therefore, Go Fast Bits, or GFB, has innovated, introducing an aftermarket solution that’s made to be installed like an OEM unit, yet provide the performance benefits only aftermarket products could.
What is a two valve diverter faucet?
Two-valve diverter. This type of diverter has two L-shaped valves and can be located in the center of a faucet that adjusts water temperature with a single dial or between the taps of a two-tap faucet. Turning the handle redirects water from the tub spout to the shower head after the desired shower temperature is set.
What does upgrading your diverter valve do?
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. By rerouting the pressure back to the compressor inlet, diverter valve keeps the compressor wheel moving and decreases turbo lag.
Does a diverter valve make turbo flutter?
The opening of the diverter valve via vacuum sucks charge air. The excess charge air is blown out via a hose, which leads to a hissing noise. If the diverter valve is broken, the turbocharger makes a noticeable noise and that Pop-off valve flutters.
Is diverter valve good?
But as far as DV/BOV's in general, what they do is let excess boost/air pressure off when the throttle plate is closed after being in boost. This keeps the boost from going back into the turbo which cause compressor surge, which can damage the turbo. So basically a DV is there to prevent the turbo from killing itself.
Does a bypass valve add horsepower?
A bypass valve vents the extra boost pressure back into the inlet when the throttle body closes. For a street car, it comes down to horsepower capability and your individual combination as to which one makes the most sense for you–or whether you want to wake up the whole neighborhood on your way to Cars and Coffee.
What makes a turbo whistle?
What causes turbo whistle? Turbo whistle is the sound of the compressor inside the turbocharger speeding up (also known as 'spooling up', which is why it kicks in at the boost threshold (when the turbo starts to kick in) as you accelerate up the rev range.
How do I make my turbo flutter louder?

It needs to be like a metal pipe for the echo to be louder because this is why you need to get a metal intake pipe.
Do Diverter valves make noise?
The bottom line is if you vent to atmosphere with a MAF sensor you MAY use fractionally more fuel (depending on the kind of driving you do) and there is a chance you may hear some popping in the exhaust. For people who just want the maximum noise from the valve this is usually not a worry.
What is the purpose of a diverter valve?
Diverter valves switch the flow of water between the tub faucet and the showerhead. Water flows directly through the faucet and into the bathtub when the valve is open. When the valve is closed, water pressure forces the water to run upward to the showerhead.
What happens if you unplug the diverter valve sensor?
Unplugging the connector will stop it working and cause the compressor stall. The ECU will also see it and store a fault, with the likelihood of impaired performance.
Can I run a BOV without a tune?
A: Tuning is not required for BOV's, so you will be just fine to bolt this right up!
Is a BOV worth it?
Performance-wise, BOVs can have a slight negative affect in applications such as drifting. When you're on and off the throttle all the time, releasing all the charged air can hurt throttle response and give some lag. But as a general rule, you're better off having one.
Do you need a tune for a bypass valve?
No tune required, it adds no performance benefit and makes no additional noise. If you have an aftermarket BOV then you need your tuner to adjust for it. The Mountune BPV isn't a BOV.
Where is the diverter valve on a GTI?
You can find this diverter valve right at the compressor housing of the Golf GTI, which is located at the rear of the engine, close to the firewall. Its construction can be simplified to a solenoid and piston.
What happens when you release the throttle?
When you are in boost and release the throttle, the throttle valve shuts off almost entirely while you still have all this pressurised air in the system. This air has nowhere to go, but out through your turbocharger which is your intake.
How does a solenoid work?
One, the solenoid operates the valve directly, meaning that it works against a lot of mass and pressure. Second, the return spring can’t be too strong since the solenoid won’t be able to operate the valve, limiting boost levels.
Do pistons need springs?
One for the piston and one for the valve itself. You might figure that the piston doesn’t need a spring because of the equalized pressure, but having one allows the piston to be ‘smart’ per se. That is, it won’t open unnecessarily if there’s insufficient boost, even if the onboard computer tells it to open.
Can a GTI go faster?
For those that love unbridled speed and reckons the Golf GTI could go faster , there’ll come a time that you want to increase the boost . The stock diverter valve’s spring is typically too weak to withstand increased system pressure, causing boost leak.
