The same valve could also be used as an overboost protection with the addition of a pressure switch.

Think I've done as much as i can and this is as good as I can get it - within a few hp.
After reviewing / analysing many logs I have come to the conclusion that the Brettspeed port modification has done ............................ Nothing good .
Low end seems to have suffered a little and top end seems about the same . I'm pretty sure a dyno will confirm this.
Disappointed . Now considering pulling it out and going back to stock port runner.

Swapping it out now and leaving everything else the same will tell the full story . At least I made it so i could pull it out without disassembling the engine

Well - not everything ....
*The engine build seems solid
*The gearbox has worked out well .
*Stock fly feels better
*The larger compressor wheel : in hindsight I think I should have left the 57 trim in there . Removing the port mod will give me a better idea though.

great thinking - had actually thought of using a vfad solenoid but it would work much better if i had the BOV line going through that and then connected the vacuum tank to the dump port . The solenoids on the tank are no good because there are only 2 ports.

That's what I thought, now if both the front and rear ports are inputs(One for the Vac Canister and the other for Manifold vacuum/pressure) and the one that points toward the passenger side is the output(to the BOV/BPV) and the solenoid switches between the two inputs it will work.

I've always wondered if it were possible to "yin and yang" the divider into a bigger port divided diagonally or even horizontally.

If I remember correctly the solenoids on that tank actually have 3 ports, one on the back is capped off, depending on how those ports are configured you may be able to make it work. I would have to take one of the solenoids off and apply voltage to it to see which ports open and close at what times.
