    You need a twin piston dump valve it stops the hunting or change the spring inside it for a stronger 1. It sounded great though

      Spring was rated for the vaccum i had..but maybe it couldve done the trick..still wouldn't have been the right was to install tho. And I actually have a grimspeed bpv on the way..just waiting for it so I can make a new video with that! 🙂 and also thank youuu!

    On another video I seen they were installing a Perrin blow off value and they didn’t block off the hose they used the elbow from the OEM and connected to the blow off value . I guess that recirculated the air back into the system.

    Do you know what size spring you had on the bov? I’m going Tial QR and will be using the 10psi spring and wondering if that’s what you used?

    • @totaleclipse05
      @totaleclipse05 Рік тому +3

      For anyone reading this in the future, I bought both the 10psi (unpainted) and 11psi (yellow) springs to test. The 11 psi spring I don’t think allowed the valve to open on my 2019, must not have enough vacuum pressure. The 10 psi allowed the valve to open fully under full boost and had the flutter noise at lower levels. I’ve since gone to the hks ssqv valve with the recirculating kit and it works really good too.

      Thanks for responding I just know in the past I had an older WRX it was a 2003 stage two and I put a blow off valve on it and it ran fine for a while until I sold it it may be different with that car because it was so much older but I don’t think the blow off valve piston should be opening and closing just from idling like that that’s why I thought maybe a bigger spring would help

      @@panderalexander it may work for idling but still doesnt prove a point. We all are gonna drive which means at some point it will open and that lost air will be lost and need to be counted for. If that wasn't the case then they wouldnt have designed this same bov in 2 versions atmospheric and recirculating. Put the right parts on your car because its been shown and proven that sti motors are very sensitive to such.

      It's not that they suck. It's that Subaru's have to be speed density tuned for any blow off valve; Because of its system you can't just put a blow off valve on it as i've shown you here.
