BOV este pentru echiparea cu turbo,la R53 nu are sens.
Textul nu-mi apartine dar zice bine.

I'll try to explain.
Well 1st off, we need to know why a turbocharged car needs one. As we know, a turbo spins from spend exhaust gas, and will spin down freely if the exhaust gas stops. So if a car is generating boost, it all goes in smoothly to the engine. When the throttle plate closes (ex, shifting from 2nd to 3rd) the turbo is still generating boost and effectively hits a wall, and is forced to go backwards, into the turbo impeller, causing it to slow down or even backspin. Then when you apply throttle again, the turbo has to take the time to change direction again, and build boost again. The BOV is placed in between the throttle plate and the turbo, so that when the throttle plate if closed, the BOV opens, and all the air is let out through it, and not back to the turbo, keeping the turbo moving, allowing you to build boost much faster at the next shift.

Now, why don't we need one? Unlike a turbo, superchargers are connected directly to the engine. Meaning that as soon as we let off the gas to shift, the s/c spins down with it, and then spin right back up as soon as we're back on. Basically, the charged air that a turbo has to deal with between shifts is not there for us, and the little that there is there, is dealt with by our inter bypass valve (connects pre and post s/c). I hope that clears everything up."

adica cu alte cuvinte BOV (blow off valve) elibereaza presiunea din turbina, pe care R53 nu o are

Exact, dar am vazut niste chestii comice ,BOV face un zgomot specific si unii isi monteaza(americani am vazut)un generator de sunet si un difuzor care intra in functiune cand pedala este la fund si face zgomotul acela specific.Ar mai fi o solutie sa poti folosi BOV la R53,asta de mai jos(sa montezi turbo pe R53).

multe lucruri deja s-au mai discutat pe forum, incearca sa citesti. daca nu gasesti raspunsurile, deschide un topic al tau si veti discuta acolo, lasati omul sa-si vanda piesa :)
