Lotus and Mercedes have been the only teams as far as i’m aware testing the passive DRS. Lotus actually ran it during the race on Kimi’s car in Silverstone. Mercedes had it on Rosberg’s car in FP1 at the Nurburgring. Its obvious these two teams are trying to master the concept for Spa and Monza as its likely to be of greater benefit there due to the long straights. What my question is, is what is the potential performace gain per lap of this passive DRS system as it must be pretty substantial for two big teams to pouring in so much resources to master it.

Actually, Spa will be a very bad place for the passive DRS.
It has to stay closed through Eau Rouge and Blanchimont, some of the fastest corners on the F1 calender. So they have to tune it so it only activates at really high speed. Meaning, they will only benefit from it down the Kemmel Straight. For the rest of the circuit it will be completely useless.

It won’t have to, at least not in Blanchimont, remember they could easily go through there with DRS open last year. Eau Rouge won’t be a problem either most likely, it’s an easy flat these days.

They will probably lose time in the middle sector though, especially in Pouhon.

Guessing Monza will be the best track for it – surely Silverstone would be hard to do as it has many high speed corners (Maggotts-Becketts for one)
