im going to say a check valve but i dont know because you wrote over the whole schematic so i have no idea where that is going to or from. good game.

BOVs tend to be more trouble then they are worth on a stock engine. you have to get the correct type and adjust it correctly, otherwise your car will run like crap. just stick to a DV you dont need to flow that much air anyways.

 

I see, this what i should of checked in the first place. i feel like a dumb ***

 

Wow...reviving a dead thread. Thanks for searching and not being a total 100% undeniable complete NOOB

 

Ok so are there two kinds of diverter valves? Kinda confused. There are the ones like the forge splitter that you hook up to the two hoses and then there are ones that are electronic like this?

Im new to turbos so i dont really know much. Thanks guys.

 

The link you posted is for the 2.0T FSI motor. Not applicable in any way to our cars.

 

Pretty confused my self right now?
As far as I know its is not recommended to run BOV on our cars. We should be running DV and have pressure recirculate back into the spooling turbo.
Correct me if im wrong but BOV will cause bigger turbo lag between shifts and overtime can cause our turbos to fail prematurely?

 

use for the n75? Will this increase boost just by adding it? Does the ecu have to be set at higher boost for this to work? Im used to just useing a boost controller

 

Any advice on which blow-off valves to purchase? Bought one once and it was a piece of crap. Thanks.
