is the minis blow off valve silenced and if so can you take the silencer off? wat would this do a friend of mine said it gives it a nice pitshh sound as you shift? true?

 

The mini uses a bypass valve, not a blowoff valve.

 

my bad.....but is this all still true

 

Have you ever heard a turbo'd car?? That sound.

 

yes i have heard that....

 

The Cooper S is supercharged, there is no blowoff valve. There's no way to make that quick burst of air sound with our car, sorry to dissapoint you.

 

Yes, you can do it. Check here:

If I ever see a MINI with this, I will beat the driver silly! No, seriously.

 

I agree... I would just out of my car and beat the ever living hell out of the driver.... I would feel pretty shitty if it really was turbo'd though so maybe I should set up a screening process

 

If you want just the sound, there is some 'simulated' turbo blow-off tone generator you can hook up. Check out some of those Honda tuner type magazines ads in the back. It does sound like a real blow off valve.... I
heard an Accord with one and it was pretty funny.:smile:

 

That Nice. But why not get the real thing. A twincharged Mini, 250 hp at the wheels. I drove it, amazing. And has blowout valve which will work for real.

$150.00 for a fake turbo sound?? That's way past stupid!!

 

Another difference between a turbocharged engine and the Roots-type supercharged MCS is the location of the throttle body. In a turbo (or a centrifugally supercharged engine), the compressor forces air through the throttle into the intake manifold. When the throttle is closed suddenly, a pressure wave can build up against the throttle and bounce back to the compressor causing at best an unpleasant sensation and at worst serious damage. In the MCS, the throttle is UPSTREAM of the supercharger, so it never sees compressed air. Slamming shut the throttle by lifting off the gas does nothing more than reduce the pressure on both sides of the supercharger. The bypass valve in the MCS goes one step further in allowing intake air to pass through the supercharger without significant compression.

So, the moral of the story is, a BOV is neither necessary nor a good idea for the MCS.
