BOV on a Aerocharger setup?

[mattytm3]

I was curious if it would be benificial to put a blow off valve on my aerocharged 95 m3 setup. I was under the impression that everything in this turbo is self contained. I do know that there is no waste gate needed because there is no wasted exhaust pressure. If it would be a good idea what BOV would be a good choice?

What is an "aerocharger" ? I'm not sure if I have heard of that one. How is it setup?

It was originally a Mectech turbo kit. It utilizes a varialble vane turbo charger( Aerocharger) which is said to produce boost in half the time of a standard turbo. It has its own oil resivoir (self contained) and has no wastegate because all of the exhaust gases are used I believe so it is not required, this turbo produces alot less back pressure than your standard turbo too. Simular turbos that are made now use a varialble nozzle.

You still need a CPV (compressor bypass valve, aka blowoff valve). That book in your avatar explains why.

Ya I love that book I havent been through the entire thing but if someone wants to know everything about turbocharging Corky Bell is the man to explain it. I believe the blowoff valves job is to release the uneeded pressure when shifting or depressing the gas at any point. But if you heard the aerocharger when I depress the gas It sounds to me like it is blowing off or relieving pressure so I wasnt sure if I actually needed to install a bov or.

If your aerocharger doesn't have a BOV built into the compressor housing (like Volvo turbos), then you'll want one.
