I purchased the QRJ but there's no solid diagram or instructions that come with the bov. I have seen pictures of it being installed both ways, so which way is the correct way? Currently I have it like this (opposite of the OEM valve orientation)

TheRealDirtyDan

No one has experience with this bov?

In your pic, the port point down is the outlet (to intake pipe), and the port point to the charge pipe is the inlet (to charge pipe).

TheRealDirtyDan

Correct. Is that the right orientation? The OEM diverter valve is opposite of that, with the inlet being where the valve seats, and like every other bov I've seen. I have seen this valve being installed both ways so I don't know the correct one

Yes, that's the right way. If it wasn't I wouldn't have called the ports what I did.

TheRealDirtyDan

Got it. Thanks for the help!

My setup has developed bucking and popping that I am attributing to my Synapse Synchronic so i'm thinking since CBRD recommends this Tial over it i'm going to swap it out... not cheap tho, but I'm at 30 PSI of boost so I doubt even a crushed 9 is going to work for me.

^Based on what? How long have you have the Synapse installed on the car? They will need to be rebuilt (relubed) from time to time. I just think it would be wise to confirm what the issue is and try to remedy it prior to simply throwing money at a new DV because CBRD prefers one unit over the other. CBRD is a good shop and both valves are solid but Im on the camp of figure out the issue instead of guessing and buying new parts that you may not need.

I got immediate bucking and harsh part throttle with the QRJ valve. I reinstalled the OEM valve after like a week

Yeah, I would pull apart the synapse, see if it just needs lubed and fresh orings. The QRJ certainly won't help with BOV flutter...LOL

What spring? I am using 1.5 and it's smoother than stock.

Oooo... Ima try this. Ordering now.

TheRealDirtyDan

Was running the stock “turbo” 3 psi spring. I’ll try the 1.5 one then, thanks razor

Edit: you have it installed the same way as described above correct? Not the OEM way?

yup:

The valve may not even need o rings but honestly they sell a rebuild kit that comes with their lube and the o rings together so not a bad option. They come apart very easily but just be very careful when putting the allen bolts back in as the casting for the synapse is shall we say not the best. But after a year of the thing sitting on my work bench I finally got it installed and I must admit driveability is fantastic, the synapse that is...
