Is anyone using two blow-off valves on their high powered engine? I've heard of guys doing it, usually because they have a BOV and then start upgrading to crazy boost/hp and need one to flow more, and instead of shelling out lots of $$$ buy another unit like the one they already have.

Any pics?

 

I have a friend using 2 BOV's for his single turbo FD Here's a picture for you:

Usually you won't need it unless you are boosting pretty high and then suffer from compressor surge. Or if you have a crappy one then you will need to get another one.

 

Garfinkle uses 2 ,one is the stock, the other is on the elbo to the throttle body .

 

I do, just because im non-sequential and I like the noise.

 

when i do my motor swap i plan on running two greedy type r's or type s's, i love the way they sound...
