Default TIAL 50mm Q BLOW OFF VALVE BOV

I am contemplating on purchasing this BOV with a 9 psi setup. Does anyone know how this sounds. I am running the Greddy RS bov at the moment. I have a tial wastegate and I want the tial bov, i just dont know how it will sound.

Also, i am running the TN kit, will this just bolt up to the flange on the TN kit or will I have to do mods to the piping?

What is the diff between the old version and the new? How much are you willing to part with it for? What is the spring lbs? What color?


Dammit, I didn't want to have to get anything welded on. I guess I will wait until after HIN to get this mod completed.

I heard about this valve...blows off 60% more air? Anyone know about this? I was thinking of upgrading as well as long as it is a direct plug-and-play into the PL kit

The Alpha Q (recirculating BOV) flows 6% more than their regular Q BOV which is vent-to-atmosphere. looks like it should be direct replacement on the PL kit, but it's not vent to atmosphere so no cool wooshy sound.

I can't tell any difference in the sound in the top vid between the current BOV and the new Q.

However the Q is supposed to flow 60% more and it is a direct bolt-on upgrade for us PowerLab guys.

I wish I had the power labs kit instead of the TN kit. Do you guys like it.

Edit:

I just listened to that vid as well, I could not hear a diff, but I listened to a diff vid of just the Q and it sounded really nice.

Air moves from area of high concentration to low concentration all on it's own - so technically, it doesn't matter which valve you use, they all will release the pressurized air. The difference comes from the design or size of the piston/diaphragm, but it really won't affect anything in any meaningful manner - they all release air, which is all they are supposed to do
