    Possible ATL turbo upgrade?

    After one week of mostly calm, quiet driving I can say that fuel consumption remains largely unchanged. Next week we'll drive a tiny bit quicker to see the impact on fuel consumption.

    The GTD1752VRK combined with 3-Cylinder PD TDI. Stock intake manifold. (no porting) This setup was not pushed to the max but tuned for fuel consumption and little smoke. Still quite a difference. The green lines show the stock setup. The red lines are showing the previous 'chip' performance. The blue lines show the GTD1752VRK setup's performance. Of course: VVT motorsport.

    ACHTUNG wichtige Infos zum 6 Gang Umbau!

    Bei BNM mit GRJ (+6. Gang von CKR) brauchten wir auch ein anderen Anlasser. Schwungrad vom A2, Kupplung usw. auch von A2.

    Or could we consider a cheaper / 'simpler' (non-VNT) compound turbo setup? I.e.: one high pressure turbo for the quick spool up and a bigger low pressure turbo spooling up at higher rpms. If not worth the effort: please let me know.

    But it spools quicker than the stock turbo. We do not get that steep slope when e.g. go from 80 to 130 KM/h in fifth gear? The smaller turbo appears not to be available in ball-bearing configuration so it's slope might be less steep. So if the transient response if good enough for daily driving and perhaps not worse than the stock turbo I could live with it...

    Could a GTD 14xx be a better choice in that regard? Max power of course will be limited. (how much?)

    That Lupo might be this build https://3lvrienden.nl/viewtopic.php?f=32&t=2691 And this:

    We also received a tip about the GTD1752VRK with some fabulous dyno graphs from a souped up Lupo with 1.4 TDI. Big question: Would this turbo spool up faster than the stock turbo on the stock block? (not ported head, no water-air intercooler, etc) The graph shows my chipped BNM versus said GTD1752VRK setup in a Lupo.

    In PDF legenda and comments in email that contained the PDFs only GT1749V was mentioned, not VB. So I can only assume GT1749V... Legenda was stripped because of privacy.

    Here's the AMF versus AMF + GT1749V graph: And this is my BNM versus AMF + GT1749V As you can see is the BNM performing better below circa 2100 rpm. Also compare BNM to the chipped AMF in the top graph.

    Hmmm. What does an AMF have as a stock turbo? Same as BNM? In a graph that I got, a chiptuned AMF scores better for both torque and horsepower below 2100 rpm when compared to the same AMF with GT1749V with fresh chiptuning. At 1800 rpm my chiptuned BNM scored approximately in between the AMF and AMF with GT1749V when looking at both torque and horsepower. How can we explain this against the observations here? Different stock turbo's? Below is my `stock` BNM with chiptune:

    How would the GT 1749V compare to the stock turbo on a BNM TDI block below 2000 rpm? I.e.: we have a non-VNT turbo against a bigger VNT turbo. So we might lose some oomph from the stock ATL turbo (BW BV39?) but what difference is left compared to my current BNM?

    My favourite gearbox shop *COUGH*http://ckr-fahrzeugtechnik.de/ *COUGH* confirmed that MQ250 can take more than 250 NM...

    Possible ATL turbo upgrade?

    Thanks, then to the gearbox: Swapping in the MYP is apparently harder than a GRJ (or JDD or any MQ250 gearbox). Hopefully MQ250 can handle +20% Nm torque like MQ200 (02T, HCS) has done so far. Can anybody please confirm?

    Another way of putting the big question is; Would the GT1749V be good enough at spooling around 1700 rpm so that the 3-cylinder TDI can do 100 KM/h comfortably when utilising a gearbox of type MYP in the highest gear? I.e.: the engine should not sputter when confronted with this load under these conditions; I do not need peak-torque that low but (just) enough to drive the car with this 'bluemotion' MYP gearbox. In this video https://www.youtube.com/watch?v=lIGRWoVw8Ag an ATL with probably stock turbo does exactly that.
