If so how can I do that in a 4AGZE running 0.6 bar boost?

Recirculatory valves are very normal on positive displacement superchargers. Similar to recirculatory dumpvalves. Just attach one at the plenum and just before the supercharger.

You cannot use a blow off valve on a 4agze , well a stock one at least. In order for the blow off valve to be able to work , you need to relocate the tb to after the supercharger or basically just use the 4age intake manifold.

Why do you want a blow off valve? For the pshhht sound? If so, then there some things you can buy that plug plumb into your exhaust that do the same thing.

If you want performance improvements then google for compressor bypass valve...Last thing I heard was that a 4A-GZE already hass one.

It can be done as I have a dumpvalve on my engine currently.

However, when i swoped my sc12 for a sc14 we took off alot of air hoses which connects to the bypass valve. We also made a new throttle with no additional air filter/cone filter/air box

The sc14 have a lot less vacuum pipes then the sc12.
My dumpvalve sits just after my FMIC before it leads to the throttle.

I don't have a picture of the engine for you now Heshan but will put 1 on tomorrow.
