    So I've found with the OEM solenoid in place even at close to 100% duty we're not able to get boost over 19-20psi. This is because the OEM solenoid is not bleeding off enough pressure from the reference line to allow the normal 2x the wastegate spring range. On the dyno I added a bleeder tee after the solenoid to rescale the range. But thinking about the issue again with a clear head a better solution is to add a restrictor pill to the solenoid reference. Limiting the volume of air in as to not saturate the solenoid.

    It turns out NOS nitrous pills fit nicely in to the solenoid inlet. You just need to file them down a bit as shown. I'll have to experiment a bit to find the right size. I'll start with a .073 pill but I suspect .055 is probably closer to what I'll wind up with. Will update the thread after testing. :burnrubber:

    This is exactly what I did with the stage 2's running boost actuated gates. It worked to a point. It gave me about 4-5 psi more boost. BUT I was running a super weak spring it was starting to crack at 8 psi and fully open by 11. even with the lines fully disconnected meaning no boost referencing to the pots, they would blow open at around 22-23 psi, so the restricter pill could only do so much. A restricter pill is very common and even OEM's include then in many turbo charged cars, STI, etc. This will work, I actually made a post about it 3-4 weeks ago (below) when I was testing the boost gates. I just used mini set screws we keep in stock that cost like .03 cents and used machinist drills to get exactly the hole I needed and inserted it into the hose.

    More problems with the car, me and Dzenno were experimenting with boost activated gates on this set of turbos just to see how they would do, and it looks like we went with too soft a spring. We can only get the car to make 14.5 lbs of boost, I pulled the hoses off the gates and did a pull and had to lift around 3500 cause it was already over 22 psi. Basically the spring is too soft so the solenoids can only do so much to keep them closed, it was a failed experiment and now I have to go back down there and swap them out for vacuum gates. This means, I will not be able to bring the car to shift sector as there is no way I can get it done and tune in time. The turbos are running flawlessly, we just tried to do too many things in too little time. It happens. Car will be fixed and back on the dyno next week. The numbers we did get were very promising though. 421 / 429 at 14.5 psi, and very low acn 91 timing, soon as we get the gates swapped, we will go at it again.
    Here is the post where I talk about it, and Josh boody knew it needed a restricter as well.

    I don't think the issue is the spring, but the solenoids are not bleeding enough pressure at the stock frequency.

    Edit: have you tested the solenoids... see what you get pressure in vs out at x% DC.

    What size did you go with? Just tried a 73 jet and it made no difference, then a 55 jet and it seemed to help a bit. But not much. The 55 already looks pretty small to me. Next size down I have handy is something like a 33. I'll grind it down and try it tomorrow.

    PS. For those running the JB4 with their ST I'm also working on a JB4 ST specific firmware. Map 1 is 15psi, map 2 17psi, map 7 22psi, will have ST specific dutycycle curves, etc. Good stuff. Click here to enlarge

    Was recently beginning to consider a single turbo..Terry's mad science and FFtec's awesome fab work make it pretty tempting. Waiting to see what the 135 does with the smaller turbo.

    the firmware gonna work with the oem boost solenoid?

    is it gonna work with the g5 board, or new board for it?

    Terry pretty sure the one I ended up sticking with was a .40 drill so pretty much in the middle of where you are. .73 is too big. You really need to drop the volume down to keep from overwhelming that solenoid.

    Seriously? Are you talking about that Scion/Subarau POS's running the N/A 2.0l 4 banger? What is there to tune? Are they coming out with a turbo kit for them? lol

    I've been hearing that they will soon be making a turbo version and a SC version of those cars (depending on whether you go with the Scooby or Yoda). Not sure how reliable that info is, though. I would expect them to go with turbo on both since they both run a Subaru engine. I imagine Vishnu is anticipating that since they seem geared toward turbo vehicles.
