And if you cut the fuel not so quickly - you get a steady RPM and actual launch control. The pop-corn stuff is not good for anything but Café racers.

Or extend the metal part of the line to go below the turbo (to a cooler place) and connect silicon tube from there to the oil sump. I've uncrimped the turbo drain hose plug (the one that bolts on the turbo) from the turbo side and extended it about an inch. Working perfectly on my car for about...

Ha, this is what I've researched back then :) .

I think this is the Beru PSG used by VAG (the picture below). I've thought about this a few months ago and it seems that creating an adapter is possible. But that was all :) . For useful data logging you'll need pretty fast logger. Something in the range of 100 000 logs per second. So most car...

Agree, but I think that too early SOI can easily beat the cylinder pressure generated by a 200-300mbar more boost.

I have a question :) . My assumption is that the correct SOI for power should be the latest SOI producing most torque. Of course in higher RPM we should also monitor the EGT. And probably the EGT should be cured by more air than by advancing the SOI as the SOI advance will result in serious...

Same issue with mine GTB1756VK. Pretty low boost was resulting in surge. And it happen to be the turbo intake. I've proposed an idea how to test in another topic, but I'll do the same here - remove the turbo intake and use fine metal mesh with clam to keep the turbo from big particles. In my...

What was the peak torque with stock internals and at what RPM?

Surge can be also because of turbo intake. Remove the whole turbo intake and replace it with fine metal mesh just for a test. There will be pretty strong sound, but the surge will still be easy to hear. Of course to do that the ECU must be set to work without the MAF. Surge can also be result...

If this is 1.9 - with this boost you are pretty far from the 200bhp :) . The lowest I've heard for 200bhp is 26-27 psi with pretty efficient turbo. If it was 2.5L engine the boost should be sufficient for near 200bhp.

I've build mine AFN with same idea. It is Passat '99 AFN engine. What I have done to now: 1) FMIC, 63mm exhaust system 2) CR lowered to 18:1 (2.0PD pistons with deeper valve pockets) 3) Dbilas 260 degree camshaft 4) Firad .216mm + 25% nozzles and 11mm pump (ALH pump internals inside AFN pump...

Shorter rods. I think somebody wrote that he'll be working on 0.5mm shorter rods. With them you can trim the block and get the correct piston protrusion. Are the 1st repair size pistons shorter than the stock 2.0L pistons? If so - you can use them, but this will require reboring.

Have somebody made the PD crankshaft to work with rotor pump head/ECU? If so - how? I suppose the way is to replace the crankshaft position sensor plate, but it would be nice to know how.

ALH is not PD :) . And I guess the head is different - probably like most of the 1.9TDI with rotor pump. Check here - http://forums.tdiclub.com/showthread.php?t=354031, my last post. I'm currently running with metal head gasket from VW Golf 3 1.8ABS petrol engine. It happened to match my piston...

Running 500Nm on the stock rods seems pretty risky to me. I doubt they will survive long with this torque. It will be interesting if somebody open a stock bottom end that was producing 500Nm and share the results.

I'm looking for the safe torque for the stock PD connecting rods (the one from 101/115PD, not the 131/150/160hp PD). I'm using them in my setup - AFN engine bored to 2.0L with 2.0L PD pistons. And I'm wondering what is considered safe for the rods? I'm currently running 350Nm wtq and I suppose...

If this is EDC15 ECU (not MSA15) it can be written with Galletto. There are few late 110hp engines with EDC15. Give the numbers of the ECU and somebody will be able to tell if it can be written with Galletto. Hm, somehow I missed the above few posts. I'm unable to find information about your...

Have anyone measured the airflow with stock intake and with the SDI intake? Just a log of the MAF readings with the same boost and the different intakes will be enough.

So is there some voltage limiter in the ECU or not? AFAIK - no, as I've tuned ECUs to request up to 4.9V (EDC15v). But it looked a bit strange as I didn't saw much difference compared to 4.5V even the ECU reported proper pump voltages in 1st channel of the diagnostic data. When I tried...

Did you tested the case (internal pump) pressure? AFAIK pump case pressure is responsible for the SOI. So I would bet that this there is either a problem with the pump case pressure or something wrong in the SOI control inside the pump.
