    Now I am going to preface this, because it needs one.
    These numbers are not verified. By no means am I saying these are concrete. But then again, it's what the dyno read and to some that is all that matters. I WILL CONFIRM AGAINST OTHER DYNOS FOR CONFIRMATION. Also, we still have to smooth out the tq curve, but that will be done on the street.
    Today was the day I strapped my car to the dyno and get everything dialed in.
    Rob Finkle at Hypnotic has been tuning my car since the beginning and I cannot thank him and all of my friends for what I saw today.
    My car made 515/424 on a Dynocom 6500 AWD dynomometer here in Michigan. Again, by no means am I saying these are absolutely 100% concrete. Google is saying that elevation where the dyno is, is about 0.166mi. Do with that info what you will.
    But anyways, enjoy.
    And no, the fuel system does not have a return.

    Just gonna post this VD and bump the thread and say nothing else. Yes, the quality is shit but it was sent to me and you're gonna have to deal with it for now.

    Starting from scratch.
    Stay tuned ()

    Nice, are you going to crack the 400whp? What's your hp/TQ goal

    The car has already made over 400/400. Just recently switched tuners and started from scratch and this is where the current map puts us. We have a few ideas for the end result.

    Just mainly showing how beautiful that boost curve and powerband is, as it's not really done yet.

    Looks to me like you got just the tip of 400. Really love the art work of this curve. Boost control is a little wonky though. Should probably check WGDC and EBCS lines.

    Vdyno looking great! You might have had a blip of wheelspin there for a few RPM but overall I think it's pretty stout.

    He's definitely got a lot of area under the shaft!

    So little update here.

    Switched up tuners if it wasn't known already. I am currently sworn to secrecy on the new one, but eventually he may make himself known. I'll get some VD pics soon. We ended up starting from scratch and really focused on the boost curve and how power comes into the band and so far it's insane. Car is feeling great. Got my dump tube repaired by a dude here at work for a few bucks that should last me through the season, looking into a manifold replacement soon anyways probably coming after the winter.

    We're going to try really hard to get a solid dyno pull over 500 on this S4v2 (technically again), I am determined. But we're gonna max it out, set up a hot tune, and dial it back down to a good street tune and then get a solid tune for when I hit the track and start doing things with the car. I just really want to see what this turbo is really capable of for pure curiosity sake.

    Also going to be plumbing my VC breathers into the exhaust. Instead of doing a catch can and cluttering up the bay more and having it reek of oil, i'm pulling a page from the old school cars and running two small tubes off of the downpipe with 10an fittings on the end and routing to the VC. This in turn will create a sort of venturi effect, and pull the crankcase gas out of the VC and not reek of oil in the process, and eliminate the need for catch can maintenance.

    Kinda doing some weird stuff I haven't seen on this platform (since I have been here). I enjoy trying new things, especially now that this is not my daily driver anymore (pics of new daily coming soon along with general pictures!). Excited to really be able to dig deeper and take my time with things. More consistent updates to come.
