Audi80, I modfied the deck of the head to flow more air :twisted: Still kind of a secrect for right now...
Damned you guys :evil: secrets :lol: I did a little mod too, but I don´t know if it was any good for power :roll: Did it just becouse my machinist told me to do.
I was wondering if your mod was something similar.
Every tuners has their little secrets
Congrat guys for the great numbers.. keep up the good work!

Here's an early in-car video of my 1.6 TD:
http://media.putfile.com/Malon...audioThe audio is very quiet, so turn up your speakers. The next video will show hard acceleration w/ boost, perhaps during a race against a 16v and a VR6.
It sounds like your exhaust is hitting the beam.
132Hp on the road is pretty impressive for a 1.6.
Those runs are with the GT20 of which you say it spools earlier than the stock K24/T3? Won't swapping the turbo for a K24/T3 with push your max HP/TQ up even more?

I just bought a G-Tech RR on ebay.. Can't wait to testdrive my caddy

You have good ears
There is virtually no play for the exhaust pipe between the pan and the beam, so hangers don't help much. I may get some insulation/padding in there, however.
*edit: Some of the rattle is also from the charge pipe tapping the top of the alternator.

Yes, the GT20 spools quicker than the T3 in one of my stock 1.6TDs. Keep in mind that my engine's overbored (1 PSI boost difference?) and generally has more fuel/airflow. I doubt switching to a K24/T3 will help. Not only the GT20 spools well it's more efficient too. Perhaps I'll throw up some compressor maps for comparison.
I do not know how the GT20 will perform on a mildly tuned 1.6L with just fueling bumped up. I can't see the turbo being very laggy on a 1.9TD anyway.
What's ball park pricing on the smaller GT turbos? I have been looking at T3s for a while and know there is a huge spread, but I always assumed the GT Turbos to be $800-1500.

My GT20 turbo came in the Upsolute Stage III 1.9L TDI turbo kit I purchased in Summer 2004. My plans for the TDI changed so I decided to use that turbo & exhaust manifold for the TD. I don't know the price for a GT20 alone, or the ball park for other small GTs.

What size is the exhaust? I don't think there would be any room with 3" tubing, but we got 2.5" over my axle and amazingly enough it doesn't rattle even with people in the back. I used to have 3" on my Rabbit and it basically sat on the axle.
3" and the car is considerably lower than stock. It's definitely tight in there.
I have a Weitec 60/40 GT kit and it's speed bump problem low
(Euro spec kit so it's lower than what Rapid sells)
Do you think the 3" is really necessary or just overkill?

I jumped straight to 3" from OEM size. I have no experience with a smaller custom exhaust in this TD so I don't have a practical answer.
The VR6 guys past the 300HP stage have reported significant gains from just going to 3" from 2.5". Claimed gains are 50 to 60HP and I didn't believe it until a few more VR6 owners including a very reputable tuner mentioned the same thing with dyno charts to back it up. They weren't selling 3" exhausts either.
Of course, our TDs are not comparible to VR6s at all but I don't mind the 3" diameter anyway; it doesn't bother me and I don't feel like shelling out $ again for 2.5" exhaust with the
possibility that it may hinder flow even a little bit. We're planning on installing a custom cam and getting a larger turbo that flows a looooot more air, but first I need a lot more fuel. And the intercooler needs to be functional. I also need better tires.
Appearance wise, I have a black downturned exhaust tip that makes it look like 2" (no gaping 3" hole staring down at drivers behind me).
I do not know how the GT20 will perform on a mildly tuned 1.6L with just fueling bumped up. I can't see the turbo being very laggy on a 1.9TD anyway.
The T3 on my 1.9 is reaching 1.2 bar @ ~2700rpm, max torque of 180ftlb 3030 rpm so the GT20 would do just as well I think.
The GT15/17/20 are about €900 at the VW dealer.
1.2 bar 2,700 RPM is pretty good, I wonder how fast the T3 would spool on my 1.6TD in its current state (has more air and fuel now).
