    Doogies Phantom Black S3.......progress thread.

    OP -- have you data logged the car on this combination of software/hardware? I'd be curious to know what your peak airflows are in the cold weather we've seen this winter.

    BBT hybrid with New Badger5 high flow k04 exhaust manifold first tests look promising

    Yep. Our ChinaFold is identifiable by its CNC machining on the flanges and the brutally hogged-out outlet to the turbo. The dimension is 47mm. Why that specific size? Because it's a prime number, that's why. No other logic beyond that. But we don't ceramic-coat it. The dull grey finish is...

    Measuring Block

    oooh, block 112, eh Bill? You're a cheeky one aren't you? :smilet digitalpoint: ... I really don't know what I mean by that. EGTs are always worth measuring.

    1.8 N/A cams in a 1.8t?

    No. I don't buy that claim. Our testing was careful and watchful. The results compel me to say the NA exhaust cam is not worth the time nor effort. Instead, invest in an upgraded fuel pump, intercooling or take your parents out for a nice nite on the town.

    Badger5

    A higher capacity inlet pipe and large element filter will together give your car a bit more snap in all of the engine range. Think in terms of how cooler weather makes it feel more lively. The dynamic is similar.

    Some R&D Info to Show What we Yanks are Doing

    Why? Why is there a "need" for a larger turbine inlet? The K04-spec casting is a great match to the 1.8T engine. It can be machined to 47 or more millimeters of opening size. That's bigger than what a 2.5L displacement Subaru TD05H uses. And the K04's compact turbine A/R makes for a...

    Some R&D Info to Show What we Yanks are Doing

    We've tried a variety of intercoolers, intake/exhaust cams & intake manifolds. We posted about that on the vortex when testing the "FrankenTT". Logs showed measurable improvements, but not what I'd describe as successful remedies. No, the first and best solution is to tune for boost levels...

    Some R&D Info to Show What we Yanks are Doing

    That's me. The provocateur. That base file was actually quite close to what I'd want. It had a slight dip in boost after onset, but that would likely smooth out with some adaptations. I will warn you, though, I don't believe Maestro is compatible with wide-band 180hp European cars...

    Some R&D Info to Show What we Yanks are Doing

    Look, I understand this thread is subject to a form of peer review process. In the scientific community a paper is written, published & reviewed. Some readers see the merits, others see the flaws. But flawed or not, the dyno reading and the associated data logs serve as a good reference...

    Some R&D Info to Show What we Yanks are Doing

    A number of members here know FrankenTurbo. We're the hybrid turbo company that does business over in the Americas (not so much here in the UK, but I'm fine with that). For years I've kept a close eye on what you folks there try on your platform, and have learned a good bit. But I'm a...

    Hybrid KO4 Advice

    OK. Because we've been doing a bit of experimentation with our K03 product lately. We bought a Mk4 Jetta that was completely stock, and have been gauging the costs/benefits of modifications. Some of you might have seen what we're doing on vwvortex. I'd be happy to cover what we're learning...

    Hybrid KO4 Advice

    Well, actually none of those things. And really my interest in disparaging a competitor is pretty low. I'd much rather discuss positive things such as what's possible on K03-framed turbos. Who else thinks this thread could be good for that?

    Hybrid KO4 Advice

    I could be a smart-alec and encourage you to buy one of these. But I won't for two reasons: You'd be an unhappy customer I know you wouldn't anyway. There's no shortage of well-designed, solidly-engineered K04 hybrid turbos nowadays. Things aren't like they were when I started my business...

    Hybrid KO4 Advice

    FrankenTurbo is absolutely NOT connected to "FTG" turbos. While the name similarity is unfortunate (and, I suspect deliberate) the design and quality is definitely not similar. FTG is an American-based marketer of CX Racing products. They have all their turbos drop shipped from the...
