The mk3 1.9L TD power-quest

[gldgti]

BAH!

Spent ALL DAY Saturday pulling the dash apart to get the heater matrix out (okay, so I was helping a mate replace control arm bushings in his e46 330ci aswell...). Its every bit as bad as everyone said it would be.

Today I pressure tested the old matrix and found that it didn't leak at all until about 16psi. Unfortunately, the new heater matrix that I got from GAP was not quite what I needed - a LHD matrix is actually different from a RHD one - the pipes are a bit longer and flange to the firewall is slightly different on our RHD mk3's. So, after a bit of thought, I folded back all the steel tabs holding the plastic end tank onto the new core, and swapped the old plastic tank onto the new core. After I'd finished I pressure tested the new assembly to over 30psi, so I'm happy that the end tank swap will be fine.

After a rather more relaxed day today putting everything back together (I also refurbished the little air deflector flaps inside the HVAC system after ofcourse all of the foam matting blew out of the vents over the past few years) I set to work re-installing my gauges with the new 42DD gauge holder.

and my provent 200




I made a bracket for the provent straight off of one of the charge pipes, for lack of anywhere else really good to put it. For now I have a little clear PVC pipe with a tap in it coming off the drain so that I can see when its cought some oil and dimply drain it under the car.

One more weekend to do the rear brakes and giver her a tidy up and I'll be happy.

Nice work, dude!!

did well on the dyno today, 88 odd kw at the wheels. the car made 80 on the first run, and about 86 on the second (foot further into the carpet i reckon) - the nice man operating the dyno and my car offered that it "NEEDS MORE FUEL!" so with a screwdriver and spanner i turned the fuel screw in 1/4 turn and she made 88kw - i'm quite happy with that.

I can hear the turbo surging below 3k now so i'm a little concerned that its at a kind of tipping point. I think a better manifold would help flow mroe air at low engine speeds and improve the turbo situation, cos i dont like it surging like that.

anyway, pretty good number from the old girl. made about 230nm, which is 40 up from the last time on the dyno

[Preen59]

Well done dude. I'm impressed!!

[Jarred]

good work!

My relatively standard TDI (not mechanical, basically all standard) made 75fwkw's. I'm looking forward to upping that in the future though...

[gldgti]

Jarred,
Thats pretty good numbers from your TDI. If you look, Marco's TDI made about that on the dyno on the same day as mine and he has modified exhaust, chipped, PD-130 intake and a few other bits and pieces.

THe 1z is supposed to be 90hp stock. Any chance you have an AHU in your car (110hp stock)?

Thanks Chris, I'm pretty pleased with the result. I figure now I must have doubled the HP at the crank from stock in my car, which is pretty cool I reckon. ON wards and upwards as they say!

[Jarred]

I thought it was a 1Z, but I'll double check. I have a sneaking suspicion that it's been fettled with (either chipped, maybe injectors) but was never 100% sure. Part of getting it dyno'd was to give me a base to see how it's running, what power it's putting out etc.

Who is Marco? I wouldn't mind PM'ing him, to find out more about his car.

[gldgti]

Actually I'm not 100% sure about his username..... maybe he'll pm you

I'd be surprised if yours is a 1z making that power at the wheels if it hasn't been played with a bit. You should start a thread Do you have a boost gauge?

Nice update mate, makes me realise my own efforts are REALLY lagging behind!

Love all the blue plumbing, glad the hoses match the intercooler pipework. Those are pretty damn good number mate, my GT TDI put out only 113kw stock, and the MKV has got a bit more lard onboard!

On the Provent front, I'm convinced that it does such a good job of collecting just filtered oil, that it is safe to return to sump. I've kept over two years worth of drainage and it hasn't got any layers, no water at all. My own "return to sump" experiment has been working just fine, and it makes for one clean and hassle free install!

The gauges look the berries, just make sure you don't run up someones date watching them!

[Jarred]

I do, hits around 20psi, then backs off to around 15psi. (Another reason I think it may have been fettled with previously)

I'll start a thread once I start doing some work on it. Atm, flat out with uni, and any spare 'car' time is spent on the mk 2 VR.
