Twin BOV's add about 20HP over one BOV on twin turbo setups and a bit more on single turbo setups. Its been proven by butt dyno testing because the noise is twice as loud!!

The funny thing is that was typed with no sense of sarcasm what so ever. I bet if I didnt write this he would take you seriously and actually think he would get 20hp. ROFL!!!

Actually, don't do anything until you understand the twin sequential turbo operation and the purpose of all the parts. If you want a quick run down of the system, then just ask.

It's best to put it as close to the TB as possible.

Yea...the 2nd one isn't really a BOV at all, is it? It's a CRV, to release pre-spool to the 2nd turbo, correctly?

actually its quieter with 2 bovs cause you just reduced the air pressure through each hole by 1/2.



and my 2 bovs give me 21 extra ponies

Some cars, like the 300ZX actually require 2 BOVs since they have two separate throttle bodies...(if I'm not mistaken)
