Kwsc: pro/cons for running a BOV vs a DV?

Im going to upgrade the DV the kit comes with to either a metal forge DV or look into getting a BOV. Is there any pro/cons of running one or the other?

These are the ones im looking at:

Forge BOV http://www.ecstuning.com/Volkswagen-...BOV/ES1832068/

Forge splitter DV/BOV http://www.ecstuning.com/Volkswagen-...ke/BOV/ES8288/

Forge DV http://www.ecstuning.com/Volkswagen-...lve/ES1832054/

BOV= Blow Off Valve
DV=Divertor Valve

Both serve the same function, but a divertor valve recirculates the released air back into the intake. The benefit of a DV on MAF (mass air flow) equipped car is to keep the AFR and idle stable since its metered air going into the engine. On a Fit I don't think it matters since its a non-MAF car and a BOV will work just fine and with less plumbing. And a BOV will make a loud woosh sound than a DV since air is released to open atmosphere.

You don't care about getting rid of the big hose hose, as much as you do the fast and furious sound of the BOV.... I am wondering if you are thinking of an adjustable BOV that can possibly increase your boost...

The BOV and DV are used to limit pressure but on turbos an adjustable BOV allows you to optimize power as well.... I don't know if one can be utilized to do that though on the Rotrex super charger used by KraftWerks.... Someone is sure to figure out how to if it hasn't been already.

waste gate controls boost not bov. bov used to be called a popoff valve by some will keep you from damaging your butterfly in tb from pressure when throttles closed. a bov diverts the pressure into the atmosphere where as a dv puts it back into circlulation but undo hose and the dv becomes a bov lol.
