Based on looking at the desing of this blowoff valve it looks (this is a generalization) like a standard blow off valve that is used backwards with a second sealed chamber for the piston and modded vacuum nipples for the reverse design.
Just by looking at the CAD photos, It looks like it would remain open under vacuum. Is there a spring in this BOV? What prevents it from opening under vac?

The reason why there are so many vac fittings on the Synchronic unit, is because each vac fitting acts on a different amount of surface area. So you can actually move the vac signal around to tune the response for the each users setup. Pull-type valves are great, because they seal boost. They are horrible because they seal boost so well that the more boost you run, the harder it is for the same amount of vac to pull it open. And that is why, there is the boost-only port, to equalize the pressure on either side of the piston, so that the BOV always opens.

Very, very easy to install. It is a direct replacement for the stock DV. Some massaging of hoses required, but it fits well.
What options would you like to know about?

I run it on my car and like everyone else that has said something it works great. drive ability is a A+. I think it reacts so fast and responsive to the slightest change in throttle. Cant get any better than this one I would have to say.
Also I will be changing my uicp pipe soon so I need to order a new adapter flange. Im not sure yet what one but I think it may be a tial flange so its vband. So if you could Chris send me a link to the adapter. THanks.
