I have a D1SC with the twin IC setup running 8-9 lbs. boost. I'm planning to do a FMIC and crank the boost up to 14-15 lbs. (maxed out). Will my ProCharger BPV work well with this boost level or should I consider going with a Vortech Mondo BPV?

 

Which Procharger by-pass valve are you currently using? If is is the standard unit that ATI sends with their kits (Ford vacuum actuator), I would consider upgrading to a better quality BPV . I've never really liked the design of the standard ATI BPV and with higher levels of boost, they just don't appear to be up to the task.

 

Yea I have the standard Procharger BPV. Works fine but I am only running 8-9 lbs boost right now.

 

You could either use another one of the standard bypass valves (ATI calls it the ProFlo surge valve), or take a look at ATI's Race Bypass Valve.
