I have 3 of them so I am curious which is the best. I have a Bosch VW BPV that is made of plastic but are supposed to be great. I have a DSM 1st GEN BPV which is a very well known piece. The 3rd one is a bit of a head scratcher, it is a Pierburg that is of a Volvo. The Pierburg actually is adjustable and it is a stock BPV.

I am sure everyone will say the DSM but I am interested too see if anyone has tried the Pierburg one.

Thanks

 

i had the volvo adjustable on my crx it worked just as good as the dsm. the gay plastic bosche bov suck most of them usually leak.

 

DSM all the way. It's tested and been abused. Its a stout little unit and unless you plan on running over 15 psi, it ain't gonna leak. If you want more boost, crush the top and BAM.. you are done. It will hold 20 psi no probs.

 

+1 oh teh DSM bov. But seriously chinese ebay knock offs aint bad these days

 

i got a dsm on my crx with no problems at all

 

yes the dsm bov gets the job done

 

I plan on using the DSM but I have never heard anything bad about the Bosch unit. Actually all I have heard is good stuff about it. It is basically the same BOV (or BPV if you want to be technical) as the one used in the Porsche 996 and other turbo Porsche's.

The Volvo is adjustable which blows me away.

 

the bosche plastic ones leak at 10psi. the saabs and vw suck you might get lucky and have it not leak but i seriously doubt it. most people would not pay 5 dollars for one. plus if your looking for that cool woosh sound they dont make it. just go with the dsm or volvo unit
