Hi all,

today was second dyno time, know with my own pump. G-Tech number for peak power increasing was quit accurate.
See here the results:

first run with 1,0 bar (~15psi) -- 151hp@3600rpm / 340Nm@2520rpm (251lb-ft²@2520rpm)



second run with 1,5 bar (~22psi) -- 165hp@3600rpm / 350Nm@2660rpm (258lb-ft²@2660rpm)


here with comparement to the first dyno run and with additionally torque curves:

Hi,

as i have written in an other thread, my K14 turbo has make lot of trouble with the wastegate, so that i did not have boost for the last 6 or 7 weeks. Last weekend i have swap the K14 with a K24 turbo, but have only 9 time full boost pressure before the K25 wastegate has the same failure as the old K14 turbo. By the side the K24 turbo from a friend has also the same failure with the wastegate valve on his 1990 1.6 Jetta.

So today i change again the turbo, know to a old Garret TA03 turbo from a 1988 VW Passat. The size is nearly the same as the K24 turbo, but up to know i would say that the Garret spools earlier as the K24.

From my calculations i should have approximate 12 hp to 15 hp mor peak power and a bit more than 100 °C lower exhaust temperature, by lowering the exhaust backpressure by 1,0 bar and have the same boost pressure than with the K14 turbo. I would say that the turbine side from the TA03 and the K24 is nearly twice as big as the K14 turbine side, so using the bigger turbo should bring aprroximate 1 bar less exhaust backpressure.

Here are some pics from the three turbo, to see the differend size. What was new for me ist, that the compressor wheel from the K14 has the same size as the other to bigger turbos. Anyway i have take a look on the K14 compressor map and would say that the compressor is 100% fit for 1.6 or 1.9 TD engines, only the turbine side is really to small for tuned engine.

left is K24; middle is TA03; right is K14
























theese picture are from last week, when we installed the K24 turbo and put my second pump build in the jetta from my friend.

Dear Folks,

i am still confused, yesterday i have disconected the wastegate from the boost pipe and max. possible boost pressure is 1,2 bar, even with massive fuel injection. Even 1,2 bar is only possible in third, fourth and fived gear, in the first gear max. boost pressure is 0,8 bar. The turbo spools normal in my eyes, which means 300 - 400 rpm later than the K14 has done. So i will check exhaust back pressure next on my search of lost power. G-tech run from yesterday show up 20 kW less power and aprroximate 60Nm less torque.

Best Regards

Dear,

today i have installed the Dr. Diesel performance cam on my aaz, and will come back later with first driving results.

Hi, schönes Auto! Bin gespannt auf die Ergebnisse mit der Nockenwelle.  Was meinst Du ist mit der Einspritzpumpe von Giles los? Dein problem mit dem Ladedruckaufbau, das geht sehr wahrscheinlich um das A/R-Verhältnis.  Der Lader kam ursprünglich aus einem Benziner, oder? Ich empfehle einen VTG-Lader, z. B. aus einem VW T4 AXG.

Dear all,

@TDIMeister
thanks for you nice words and excellent german, you are from canadian or?
All turbos are from diesel engines, i don`t know what was the problem with
the giles pump, but i have to say that i have bozght it second hand, so perhaps
it is not "original giles" or some internales was changed?

I have take a look on the next turbo swap, know i will take the next bigger step
and will install an adapter for external wastegate and use a schwitzer S2a which
i allready have. Here are some pics:


















In regard of the performamce camshaft i can`t feel any advantage in comparement to the AAZ stock cam up
to know but did not have take out an objektive measurement like g-tech run or similiar. I has adjusted the fuel
amount to the acual turbo mid of last week and have had nearly no smoke over full speed range.

After installing the performance cam, i can again make the streets very dark, without any modifications on the
fuel amount. Also the Turbo spools later than before, after boost pressure come up (approximate 3000rpm) it feels
perhaps a bit stronger than before and in upper speed range i could not feel any difference.

I was wondering about a missing oil groove for the first cam bearing:




Here some more pics from the camshaft:








Be changing the cam, i have notice that the inlet hydros of the first and the fourth cylinder has a mark of the
cone point from the cam, so i decided to change both hydros with two from an other aaz engine.



Best Regards

FWIW, good camshaft manufacturers will always tell you to install new cam and new lifters together. Never reuse either one without a matched set.

Hi Alleslowbuged, since the other car in your picture has Kennzeichen aus Bielefeld, and the seal on yours is from Nordrhein-Westfalen, I assume you're from NRW, probably not far from BI. :D ;) Can you tell us, where you are located?  I lived since 2005 in Aachen.  There I studied at RWTH.  At the beginning of this year I returned to Canada where I'm from, now I'm doing my PhD (Doktorarbeit) in Maschinenbau.

Here are some pics of my car in Germany and previously my Diesel that I owned from 2000 until 2005.

BTW, I don't normally type like this in English.

Edit: P.S. - Most turbochargers for gasoline engines have turbine A/R ratios that are too high to be able to build up boost properly in a Diesel engine.  The wastegated turbos used for the VAG Diesels all have A/R ratios around 0.3x.  Most gasoline turbos start at 0.6x -- not going to spool.

x2... VERY IMPORTANT to have fresh wear surfaces. the cam and lifters get wear patterns, and they sorta like being matched wear patterns.

Hi,

i wand to build (buy) an adapter for put the S2A on the stock manifold and use a external
wastegate. The shop who has take the order did not have a drawing for the vw stock
trapezoid flange, i have make some rough measurements last time, but was not aware that
i need the dimension for manufactoring.

If someone has a sketch or a drawing i would appreciate if i could get them.

Best regards

Hi Alleslowbuged, nice car! Like the bmw as well(seen the gtec figures and videos!)
I was posting in your pump thread a while back but lost it? and was wondering are you still running a camplate from a direct injection pump? Or could you share any camplate info or research? All Ive learned so far is de145(11mm vag tdi auto) is the best lift and lever modification could be required to get full rpm. I'm about to upgrade my turbo this week (finally, k14 50trim, merc OM606) on peugeot xud engine and fear wont have enough fuel especailly for high rpm, I already have 11mm plunger, approx 18deg advance, grinded custom lda pin and shimmed governor.

Hi,

after i have had a broken injection nozzle again, the car is running again and i will drive to a 1/8 mile race tomorrow.
I have also make a modification on the front, to get more air to the oil and to the intercooler.

Here a the 2010 insect eyes for the vw golf mk II:




I have also get a few new parts for the S2A turbo swap:
