If your bov is popping openno doubt synapses is your best solution.

Flutter everywhere, tried in port B, a bit better but not where I'd like it, I then read the manual and tried PULL type port B only.

BUTTER all the time. Much better than factory turbo and factory mr bov even. The PUSH type just doesnt work well on the 9 indeed. It should be stated to try PULL type first on evo 9s

That's how it is for me as well.

btw, I got it from the horses mouth that it's no problem to switch it around.

Performance wise, there should not be a huge difference between the DV and the SB considering both products use the same Synchronic technology as the internal. However, our engineer have noticed that the SB still reacts just a tiny bit faster. In any case, we're talking about a few milli-seconds of difference, and it is not something noticeable unless it is tested on specific equipments to data-log these reaction times.

The SB is pressure tested to over 100 psi and the DV is pressure tested to 60 psi. Although both products are fully capable for high boost and race use, but the build of SB is heavy duty (as you can see) and probably be better for very high boost use (40+ psi).

The advantage of the DV would be smaller (obviously) and it is black and looks very stealthy. As you can see in the video, the DV we've installed onto the Evo 9 have black painted bolts and the silver logos were painted black as well (it was done to the owner's preference). Those of you whom live in California might appreciate the fact it is black.

The other advantage of the DV is that you can use it as Push or Pull depending on your driving style and preference. However, we still strongly recommend that you re-circulate the discharge air regardless of Push or Pull.

FYI, in my opinion, the DV works better as "pull" for the Evo 9.

Anyhow, for those of you whom already have a SB kit, you may choose to pick up the Universal DV with just an extra 1.25" hose end adapter flange if you want to simple try the DV and compare. You'll need: DV001A.001 & SB001.9A (Vibrant P/N 16501A and 16019A).

For those who will be replacing the OE bpv with the DV, you'll need the Evolution DV Kit. Part # DV001A.005 (Vibrant P/N 16505A). Please check with No Limit Motorsport 1-866-381-4618 for pricing and specials.



Don't feel bad, because the price of the SB may increase within the next 12 months. So be glad you got one now.
