[OneBadAudi]

goddamn that pt74 is HUGE>.....nice thread

[chadb2434]

Nice Thread. Good pics, Thanks!

This thread is worthless without compressor maps, dyno numbers or timeslips.

[demea]

For picture comparison it works
For stats...ehh.

[widgget]

yes but it's cool to be able to picture the differences in size when people are talking about all these turbos.

[Alphazuzu]

what car is that PT74 in?

[widgget]

it's a B6 A4. and the PT74 is just laying on top of the 3071r thats in it.

[F16HTON]

The PT74 belongs to Shawn's tech and is in his nearly 700AWHP R32

I was looking for and most curious about physical size in a picture and wheel size specs. Ive never been able to read a compressor map or understand what exactly its showing

My turbo is out of its efficiency range up here...

Heres a few pics of the R. Havent dyno'd on higher boost but a year or so ago before alot of changes it did 584awhp on 15psi. Currently runs 10.7 @ 134 with full interior on 25psi and should be in the neighborhood of 700awhp

I want to see a pic of that giantastic ass turbo in the car, where exactly does it sit?

Are you kidding? I did ... its in the car right above your response.

[A4ringedONE8T]

And you guys suck, ADD SOMETHING USEFUL!!!

What do you want me to compare? I've only used two different turbochargers on my car (beyond stock). The only difference between the two is the compressor size and compressor maps.

What I think is more useful is a table of various turbochargers and links to their respective information... specifically compressor maps for efficiency usage and the like. Then real world examples of engines and cars that use them (if applicable). We started this in the big thread in the FAQ section (which I think a lot of people forget we have such a section).

I looked through it and it didnt have much if any info in it. And internet tuners ... you haven't been able to back up shit either so your no different

What are you talking about? My car is currently sitting at a shop [slowly] getting tuned. Its not my fault the shop is prototyping a few kits for other vehicles (one in particular is a 30series B7 2.0T kit as well as more B6 S4 work) while mine has been concurrently there.

I have not come out publicly and claimed what I think my car can do and what I think it is capable of without any real-world information to back up those claims... THAT, is what I refer to as 'internet tuners'.

I am waiting to publicly say things until I have information to back up my statements. I don't want to mis-lead people with false claims.


Regarding why my Avant is not at my house right now...... I, personally, don't really care if the car is at the shop for an extended period of time. As long as some work is getting done (which it is). Why rush a good tune that works across many different operating conditions just to say my car is 'done' and I'm driving it? I am a very meticulous individual and am driving Mark to look at many different aspects of the ECu to get my car running flawlessly. Any B6 that comes in after me, in turn, will benefit GREATLY from the work I am requesting on my car. Besides, I have lots of other stuff to do and not having my car in my possession has allowed me to finally focus on other things in the meantime (outside the Audi/VW scene).

I am an internet tuner

[Maverick]

Shawn, your thread will get even longer in the future.
love the pictures btw.

[widgget]

I am an internet tuner

I guess i am a internet tuner also....

modding my A4 is a side hobby for me, learning as i go (well, of course i research first but you know what i mean). i would still be stock with my local stealership working on my car if it were not for audiforums (where i started) and audizine (where i ended up after seeing most of the cool people were over here). now i'm running a stage 3 GTRS setup and don't think twice about pulling the entire front end of my car apart.

THANK YOU INTERNET!

[A4ringedONE8T]

Still going to the track tonight Shawn?

Its tomorrow night and not sure. Just got my new injector seats put in. What a F'in pain in the ass! Old ones we're brittle as hell so I had to take the intake mani off just to change them and keep from getting anything down in the valves!

[Silence]

Go Go GO!!

Yes you (and many here) fall into the catagory of "shade tree mechanic"

I personally prefer the term "hack mechanic" as I think it's more onomatopoeic than shade tree, but both work I suppose.

[IronAudi]

Are you kidding? I did ... its in the car right above your response.

I dont see the turbo in the car, i see piping. Im saying show me where its hidden cause i cant see shit.

[demea]

Funny. About the talk of "internet tuners" that is. I'll wait for the right discussion to start about that and wont jack Shawn's excellent thread.

should spool in the mid 4s methinks... and the head will rev to 8500, should be a good time

[05A$SE]

how is that gonna fit under the hood? looks like clearance might be an issue, no?
