The 3.0 controller will have an extra dial to set the safeguard point. (for example 20 psi) If you reach 20 psi and the controller does not sense an alky pressure signal from the pump the safeguard will close a solenoid valve that will mount inline between the wastegate and boost controller. (factory or otherwise) When the valve closes the boost will drop to wastegate spring level. Sound good? Any input from you is appreciated. Will put it up on the website as soon as it is available....and after my main vendors have tested it. Thanks for your patience!
Hope to have prototype pictures up soon.......

Well if I don't ask this, Richard will. Basically as long as the pump is powered, it will allow the car to boost right? So if the pump is only putting out 60psi due to a pump going out, it will STILL allow it to boost, even though the 150psi pump pressure has not been met?
It sounds like about a 10% failsafe. If there was a nozzle clog, inadequate meth flow, inadequate pump pressure, meth leak in the system, these are just a few scenarios that the failsafe would do absolutely nothing to protect against. All of which are equally important failsafe bases to cover.
Please clarify exactly what the system looks for. Just 12V to the pump?

There are 3 filter screens in the SMC kit before the nozzle......between these and maybe an annual cleaning of the final screen at the nozzle there never should be a clog. Maybe we should hook up a laptop to the system and strap it to the dash so we can obsess over it at all times? Sheesh....

All these guy that think that that safeguard is adequate, must know nothing about meth injection nor the dangers of a system failure. 35psi on an SMC 7gph (small) jet is about enough to cover 23-24psi, not the 26-34psi that the stock turbo is capable of. Lets not butter up a protection system that lacks adequate protection, regardless of the manufacturer.

I am running the Snow Peformance kit with failsafe and for the money its a pretty good failsafe, combined with my wideband and UTEC I am pretty safe from blowing my motor.

In order for a WI failsafe system to be effective, it has to be a all rounder and stand-alone affair, or should not be advertised as failsafe or it will mis-lead the Joe public.
Minimum requirement for a failsafe to be effective:
1) Blocked jets complete or partial.
2) System pressure drop
3) Flow descrepancy
4) Overflow (due to leaky or loosen hose connection)
A tall order, but your engine would be grateful for that extra contribution. So read all small prints and ask directly question before accepting the word "failsafe" loosely - delve deeper to find out how it works and see if it gives you adequate cover for your application. Don't forget, you are on your own when things go wrong and no one to blame for.

I know it's really just half safed but it's better than some other kits advertised as "safe" I see (even the most popular) . Another thing important is how **** the installer is with the project.
The WI system itself at 25psi can be considered a failsafe against bad gas at 21 psi W/O WI.
