    Thats good enough for me! Just glad to hear it being worked on and making progress!

    Tony what about instead of spinning the hpfp from the crank, spin it electrically via a motor? That way it could be at "full speed" at low RPM. Depending on the power requirements to spin the pump, it might work. It probably wouldn't be the cheap way to do it or anything.

    We need higher flow all the way through, not just at high rpm. The HPFP needs to be designed to work with upgraded turbo setups not just on stock turbo setups. Im sure Tony has this in mind and will be developing a fix for this.

    Will this work in conjunction with your current HPFP pump and rail upgrade? I already have your HPFP pump and rail upgrade and waiting for VTT Stage 3 turbos.

    So, I am not exactly too well versed in our fuel system. I know where our LPFP pump and tank is located, and the HPFP, so does the LPFP fuel a secondary tank that feeds the HPFP, or how exactly does it work? I don't understand why we could just use an electronic pump in conjunction with the mechanical pump. I'd think the JB4 could somewhat easily control this pump no? @Terry@BMS ?

    Hmmm so if there as to be a supplemental electrical pump would the best position be at the lines feeding the HPFP, or would it be best to T-off the LPFP lines and by-passthe HPFP directly to the rail? By the sound of the things the electrical pump wouldn't have most of its workload in the midrange and not much in the higher RPM's.

    What type of PSI would the pump need to be capable of?

    As needed in direct injection set-ups, the HPFP produces an extraordinary amount of pressure. IIRC, up to 2,900 psi in low rpm, high load conditions.

    We use supplemental electrical pumps between the electrical LPFP and the mechanical HPFP (or replace the LPFP with a higher output walboro) when the HPFP demand exceeds the LPFP's abilities to keep pressure up. You want pressure above 70+psi pre-HPFP at all times so that it can be "fed" fuel properly. Electric pumps are flow rated- they can flow X gallons/hour at Y PSI. If you drop the PSI, they can usually flow more... but the HPFP needs flow and pressure on the "inlet", so you need a strong enough LPFP system to keep it fat and happy.

    Post HPFP the computer targets anywhere from 800psi to 2500+psi depending on multiple variables. So, if your HPFP is crashing, but your LPFP pressure is stable... there's nothing more you can do to help it because it's the HPFP output that has been exceeded. Well asides from meth injection, higher RPM (spins HPFP faster), tuning for leaner AFR's, less boost in the midrange or wherever you are having the pressure drop, etc.

    I'm just gonna throw it out there that any ideas you have, have probably been tried/tested. The only way this is going to be addressed is with new parts and fabrication, or a secondary fuel system. There is no trickery left in the system to be had, it's all been tried. Best bet right now is the Vargas upgrades, but they mostly address big power up high. If you want big power down low you need to supplement with meth or use race gas instead of E85.

    Yeah, I have the walbro 255 inline. Don't plan on running more than an e30 mix until a fuel option comes out, and do run a meth kit with dual 1.0 nozzles and usually run 100% meth mix

    Just as a small general update, still waiting for info to come in trans rebuild options. But I've been playing with the tuning and found if I close the throttle slightly before the up shift it seems to dip torque just enough for the trans to make it cleanly in to the next gear & hold full advance. I'll have to do more runs in various climates to ensure it's not just a red herring. But this may be a good stop-gap for me to enjoy the car a bit more before we can build the trans up. Click here to enlarge

    Also I started picking up an intermittent bank1 o2 sensor code a couple weeks ago. Which I was dreading swapping as it's all packed in pretty tight. I was worried I might not be able to reach it without pulling the turbo. But I'm now pleased to report it can be swapped without issue. You just pop off the compressor cover and using a stubby 7/8" wrench can get at it from an angle. Maybe 20-30 min of work. Phew. Click here to enlarge

    No it's just all 100% stock. An eternal cooler is probably a good idea at these power levels though.

    Check out my thread I just created. I will be running one with my ST as well ill let everyone know how the transmission reacts to it .

    Log looks pretty good T. When are you going to go past 20psi? Is there currently a ceiling at 20psi for some reason? I don't remember.

    At the moment I'm having problems holding timing post shift consistently at any boost level. Works great one day. Then the next day dies. So slowly trying to work through that.

    The JB4 runs everything. The flash is setup in such a way to simply certain things for the JB4.

    I can't directly comment on level10's quality, but common sense tells me that if the upgrade was the answer, everyone would have it.

    It would be nice if people that have this upgrade commented on how it's holding up.
