So what is the best tranny solution for high hp audis like Hanks? What part of the tranny seems to fail the most.[/quote]

It depends on what your using the car for. The tdi transmission with the flexible main shafts save the first gear but have been known to shear off with very high horsepower and hard racing conditions. The regular main shafts have been known to gall first gear with similar abuse.

The 1-2 collars are problematic, mostly due to the shifter design of the C5 and B5 cars, as 1-2 collar problems are almost non existent in C4 cars. There are updated pieces which fix this issue, but you won't find a factory transmission with those pieces installed.

The later tdi transmissions (2003 and up) had a pump, standard capacity sump but the first and second gears are even shorter than the standard 01E (3.75/2.14).

Since the terms better and best are entirely subjective here are three scenarios taking into account engine and car use.

The "Best" transmission utilizing factory parts would look like this for a low displacement street car would be:

Allroad TDI high capacity sump with pump
4.11 final drive
3.50/1.89 first/second
1.32/.93 3rd/4th -- There is also a 1.43/1.07 but 4-5th spacing would be pretty wide.
.73 5th
.60 6th
Updated 1-2 shift collar parts

The "Best" transmission utilizing factory parts would look like this for a large displacment engine

Allroad TDI high capacity sump with pump
3.89 final drive
3.50/1.89 first/second
1.23/.87 3rd/4th
.68 5th
.56 6th
Updated 1-2 shift collar parts

The "Best" transmission utilizing factory parts would look like this for a track only car

Allroad TDI high capacity sump with pump
4.35 final drive
3.50/1.89 first/second
1.43/1.07 3rd/4th
.86 5th
.76 6th
Updated 1-2 shift collar parts

However there are power limitations to the stock internals, at about 600 wheel hp in a racing environment I've seen, 3rd gears shear and first gear loose teeth with drag racing.

So... how'd the dyno go?

Dyno didn't happen but tuning did and there should be some good burnout videos appearing in this thread soon. Hoonage did happen.

I was down at Hank's shop when he did that and it was echoing off all the buildings! Everywhere Hank went it wasn't ever less than full throttle. No wonder he went through 3 tanks in 3 days!!! :thumbsup: 35 psi in the HTA35R and E85 in a 2.6L engine....a beast!

Thanks to Hank I now know what it probably would've been like to ride in a Group B car. The torque that thing produces is absolutely amazing.

No problem on the rides. Darin is right, I beat the living piss out of the car all weekend, put 3 tanks of e85 in it at 22 gallons+ each time, and the only real issue was a slightly leaking valve cover gasket that was putting a little bit of oil into the spark plug hole. I could probably use a new expansion tank cap too, but give the thing a break, it was putting up with donuts and 0-90-0mph blasts up and down the parking lot all afternoon. None engine related, the passenger door latch was a POS all weekend.

Red rock was a blast trying to lose, and then trying to catch Jimmy Green in his Yellow 'nana. With another 240+ fellow in the passenger and with Jimmy solo, we were just about even in 3rd gear with the same gear ratio at 4500rpm roll ons as you would expect with basically the same turbo, but I could grab him a few car lengths in 4th down at 3500 rpm rolls pretty easily. Think my 2.6L still spools about 300-400 rpm sooner than his, but the top end of his setup is really nice. You can feel when the valve opens and lets hell loose. I don't look down at the dash too much anymore while driving at 35psi, but my passengers commented that I was shifting at around 7200 all weekend long. I finally paid attention a few pulls, and sure enough, my brain must be communicating with my butt dyno telling me the power is dropping off, and more meaty power/torque is available if I shift. This makes me long for hte 1.03 housing I have to see how it behaves. My hunch is that it will make the 2.6L spool identical to a spool valved 2.3L of Jims, with teh same top end. Pretty impressive for the spool valve if you ask me. Makes me long for the best of both worlds.

Didnt get on the dyno this weekend, but Jim and I both agreed that we probably both have cars hovering around that 550whp mark untuned, and probably more like 625 when tuned on the dyno. Hopefully Rudy or Jim will post up some vids from the chase around redrock.

Very happy overall with the state of the car. Can't wait to get it on the track

Also, my GPS showed 270 miles of total driving over the weekend, which puts me at a wholesome 4.08MPG.. That is how hard this thing was beat on this weekend. 1600cc injectors over pressured to be more like 1800cc injector at peak 92% duty cycle means almost 8.2L per minute at full throttle.

Hey, what was the coolant drip coming from or was that something else?

Were you both running 35psi? Those are some great first hand impressions with the cars side by side. It'd be great to see the exact same turbo on a stroker and then on a QSV'd car. So best of both worlds = about a 900rpm improvement? That's a hell of a lot more turbo for the same curve. 550whp is pretty impressive for not being tuned.

Also, LOL at your mileage. Wow. I want to see vids of the banana vs urq!

Ok, ok, ok.....since everyone seems to be talking about next year already, I propose a drag race at midnight mayhem to settle all this Green vs. Iroz unsettled business.

holy crap! you guys both running e85 then? Jim, how much boost?

I was on pump gas and water meth injection at 31 psi. My car is fast, but Hanks car is brutal. There is no doubt he has more torque, but I think I might have him on the top end so it makes for a fun comparison. He got a pretty good jump on me in the 4th gear pull. While I was waiting for the turbo to spool, he was motoring away with his torques. The dyno would have been great to have, but we would probably still be there on it. I think it would have made an already crazy day into an even more exhausting day.

It would be fun to drag race, but I am just not into it. I have actually welded my clutch to the flywheel once screwing around launching the car. It took a rather high speed highway pull in 5th on the brakes, with the clutch in, at full boost to break it free.. I would rather torture my drive line drifting around turns :)
