G-Teched my 1.6TD - Baseline Runs

[Audi80]

Ok, so Itīs a secret I`ll have to find a cam grinder here from Finland who understands of diesel cams. I believe that there isnīt that much knowledge about diesel hp cams.
I have about half dozen extra stock cams, so I could do some testing too if I find a decent grinder.
BTW Is the NA cam same as TD cam?

No the NA has different specs then a TD from what I understand, at least thats what my cam guy tells me :?:  Also a good cam grinder should be able to convert solid lifter cams to work in hyd heads, which obviously have different specs. From what I understand every iteration of the vw diesel got a different cam 1.5, 1.6 solid, 1.6td solid, 1.6 hyd, 1.6td hyd, 1.9idi, 1.9tdi ect...

As far is it being a secret it will only be that way until someone buys one and measures it. I don't honestly know or care, what I know at this point is that it spools way quicker, like 500rpm's sooner and as such the egt's are slower to build and stabilze at a lower final temp obviously that temp is dependent on the car's setup and not on the cam, finally it seams to hold power better into the upper revs, though this data is still being collected. If someone wants to buy one and then posts up the measurements I am fine with that.  :wink:

my apologies to bring back such an old topic, first off...

However, I think I've done the same as malone to my 1.9TD... A little bit of 170 km/h cruising + 24 pounds of boost = rawr.

I haven't taken the head off yet, but I suspect low compression... Not as bad as malone's 1.6, I hope, but still too low to be reliable. I did, however, drive the car home from 100 km's away, after it started showing signs of unhappiness.

I'm thinking rebuild the bottom end, if the cylinders aren't too damaged. But, worst case scenario, what other options do I have, for say, a PD swap? How much are those running these days?

You'e looking at around $2500 US for the engine most likely, www.carpart.com is a good place to look, there's a selection at least.

i really don't understand why this happens?? i can't even count howmany times ive run my car at a gps verified 57meters per second(205km/h) at 35plus psi and the only thing that eventually failed was my turbo??? my engine is almost at 500k and still has 430psi compression. am i just running enough boost to keep my egts down? i don't have a guage so i have no idea what kinda temps im running at that speed.

PD swap... if you're doing the 'econo' swap then you're easily looking at $3500.  but don't stop there, as the 020 tranny isn't doing much for the motor.. you will want to get the proper tranny as well.

you don't even want to know what i'm shelling out for my PD swap...  :oops:
