It would be pretty neat but i doubt any after market companies will make something similar because they would also have to setup a control circuit to trigger it. You probably could make a standalone trigger it but that might be a huge PITA.

It is, it says so in the article....
I would get one and use it parallel to my BOV and connect it to a Pressure Switch with the simple purpose of over-boost control...you could even hook it up to a knock sensor for knocking protection...hmmm...lots of ideas...

It makes you wonder: is the tension in these BOV's set such that they intentionally leak at a certain pressure, or is the overboost control performed electronically by the Taurus ECU?
If Mazda had used an electronic charge relief valve it would've saved some hassle and plumbing on the FD.

eventually those Taurus blowoffs will start turning up on ebay. until then, I don't think there are any other OEM ones to test and certainly no aftermarket ones. and you know a brand new Taurus BOV is going to be $Texas from a dealership, plus you'd have to machine a flange and cut a custom gasket to make it work.

It would be great to tie it into a flow control circuit for AI, like the Safeguard from Snow Performance. Much better than simply de-activating your EBC. I was looking for something like that!
Does anyone else think it's cool that there's a TT taurus?

E-control for BOV is here
Hi all,
Just a FYI:
A standalone, in-cabin tunable, electronic BOV gauge controller is about to come on the aftermarket.
There are 2 options. A 52mm version and an 80mm version. Both Backlit. The 80mm is powdercoated in optional colors.
The 80mm feature list is as follows:
1) Electronic Boost gauge - Vac/15psi or Vac/30psi switchable
2) Smart NB Rich/lean display - considers 15:1 under vacuum or 12:1 under boost as lean levels. Good for basic tuning or warning.
3) Indicator LED & Relay drive for a tunable boost level alarm setpoint.
4) Indicator Alarm LED & relay drive for dangerous Lean/boost conditions.
5) Smart Turbotimer based on boost level- onboard activity led.
6) Solenoid Blow Off/Bypass valve controller with tuning for sensitivity and duration. Scramble switch preset to activate/deactivate max sensitivity for Time attack or moderate street driving.
The 52 mm version is targeted at the higher end of performance with a Vac/40psi elec/ boost gauge and this presumes you already have a turbotimer and an a/f meter.
Also, items 3 & 6 above are included.
These features in combination permits the BOV/CBV to be under precise elec. control AND be used as a no-leak, pop off relief valve in overboosted conditions.
Operational parameters allow you to tune the blow off to fire BEFORE the compressor surge gets going (by detecting variations in boost pressure gradients).
This permits better spooling and throttle response. Further, the duration tuning allows you to setup BOV closure to preempt your lifting off the clutch so as to precharge your I/C with a few psi (from turbo inertia) for max throttle response.
One other first for the 52mm gauge/controller:
In order to deliver max. resolution in a digital gauge it delivers 540 degrees of sweep. That's about 100% more than other gauges. It does this by bar/dot mode and color switching of the LED display to form an intuitive hi resolution display.
The products are being street tested as we speak, with dyno throttle response data to follow, then a magazine feature along with a product launch.
One other thing - an option exists to control your installed BOV once you can ensure it has a SOFT spring. Thus negating the need for flanging etc.
If anyone cares to hazard an informed guess as to the street price of this product, we'll give you one (preprod. release) if you're within $10.00. This forum only, this thread only, one guess each, two giveaways, our decision is final, we will round to nearest dollar. Please give a short reason for your guess.
Each giveaway can have a custom faceplate done to include custom text as governed by space & size.

The controller only as it's coming from outside the US, its cheaper for you to purchase the solenoid locally. So we are giving only the controller/boost gauge away.
For maximum predictable & tunable response we recommend using a direct 1" brass, viton diaphagm, user serviceable solenoid. Then you will have to have an adapter flange made to get that installed. That's good for average blow off to 20psi or so. It will hold over 100psi.
That goes for around $45 for the valve and local prices for flange fabbing, perhaps another $30. We will be looking at supplying adapter flanges for popular vehicles soon to simplify installation. Of course, all this is offset by making your BOV obsolete, so u can sell it and come out with a few $$ extra probably.
If you have a decent adjustable BOV now and are running over 20 psi, you can probably go with the vacuum canister, check valve,& 3 way, 1/4" ,solenoid as the interface to drive the installed BOV. We supply those components. Set your BOV for the softest spring setting. You can even shorten the spring to soften it. This install is simpler and u get to keep the style of BOV you have.

I'll guess $145, because it's in the range of other types of controllers like Auxiliary injection, fan controllers, etc. as far as R&D and components to make the controller.
