I've gotten 0 tuning done because I've had to fix all that other crap and try to work at the same time haha.

    Sorry to hear it won't be at SS but no reason to rush. It'll work itself out.

    Good luck!

    Keep the data coming Tony, good stuff!

    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.

    josh you are 100% correct they cannot bypass enough to effectively control the boost, I have a work around I am trying right now.

    We also basically completely removed the stock LPFP fuel system from the fueling loop, we are running the walbro 455 intank, across to the drivers tank which has the stock regulator completely removed, that feeds a custom surge tank fitted with a bosch 044 inline pump sitting inside the surge tank for cooling and lowered sound levels, this feeds to a real aftermarket regulator, which is boost dependent and adds 1 psi of pressure for every psi of boost, this is regulated by a return line back to the surge tank, basically turning it into a return style system. From the surge tank forward, and the returns are Aeroquip -6 push loc hose rated at over 500 PSI. So far the system seems to be working flawlessly. We will see how it does once we get some real HP asking for fuel.

    Is this needed for stock frames? Not at all, but we are in the works of building a motor and this will be needed for 800+ WHP. So we just like to do it once.
    You've got me thinking all crazy about this fuel system now. Did you fit the surge tank in the drivers side of the fuel tank or is it external.

    You didnt by chance use one of these did you?Click here to enlarge

    We used a different surge tank that costs a whole lot less than that, it was around 200 bucks, and my regulator was only $109 so it was quite a bit cheaper than that guy. We mounted it externally, but its all pretty hidden, you cant see anything in the engine bay or underneath the car unless you really start digging around. So far its working pretty good, the HPFP in this car is going out, (shocker another problem) I will be pulling that tonight.

    Tony, this is meant to be a solution for running straight e85 correct? Wouldn't mind seeing some pics of the setup once it's done, I never even thought about a surge tank.

    Honestly, as of right now, I am not seeing much benefits of this system over a the stock system with either an intank or a inline for these WHP levels. Its the right set up for high horse levels but totally over kill for anything like stage 2. We are running Straight E85 right now, the HPFP is literally dropping to 600 psi, it has to be taking a $#@!. Honestly I am just sick of working on this car, I just want to get these stupid boost gates off, swap the HPFP, get it back on the dyno, crank the $#@!er up til the I think the turbos are going to break and see what we get.

    Try installing one of these. It'll bolt up, but not sure if it will actually work.

    It looks like someone converted the housing to take a plunger style pump. If this is the case, thats pretty bad ass. You got a website I can check out?

    I mean, sure its a new style, I mean thats all well and good, but who says it flows anymore than the pump we have now? I agree this style would be easier to get a better flowing pump on it since its a plunger style. But I highly doubt BMW just went to some super flowing HPFP for a stock car.

    True, but the pics of the new s55 engine look to use the same setup.

    Its nice to know theres at least the hope of another option. More then we had before Click here to enlarge

    Ok, well that car comes with 4XX HP. The pumps we have now easily support that much, and with a few tweaks on the bigger turbos it flows enough for 700+ WHP. It just has issues with the massive TQ of the upgraded stock frames. For $1100 I am just going to have to wait and see how it plays out. I actually almost pulled the trigger on one, right after you said what it was, but I came back to my senses.

    I don't think he meant that in it's stock form it would be sufficient for what everyone is looking for. Just that due to it's revised design maybe it's better to modify than the pumps that are currently being modified.

    Newer doesn't mean better. But hopefully this is true.
