Tiptronic transaxle, Anyone know these? Options

[r_towle]

Does anyone understand the Porsche tiptronic transmission?

Specifically, does it need a special ECU and/or does it have its own?
Does it even need a computer?

Looking to use it for a rear engined Subaru project.

Any super experts on these transaxle out there to get one custom built for this?

Really looking for an automatic, no flames.

A PDK controller is coming. I am building a 4.1L 993 engine that it will be coupled to, and fitted into a Beck 904 in the spring, for its initial testing.

Tip trannys are heavy as hell, but they are bomb proof. The size alone makes them not very viable for any older retrofit.

PDK trans might be bomb proof, but the older Audi trans can only hold about 300lbs of torque and are considered fairly weak. They also have a really low stall from the factory which leads to premature wear. But they are easily tuneable.


I know a guy that can tune the TCU and might be able to make it standalone pretty easy. I havent priced it from him but I am sure it would be about $300 or less. Daz Dillenger (find him on Facebook, tunes hundreds of cars a year remotely from his house). If your serious, he is the one you need to talk to. (IMG:style_emoticons/default/smile.gif)

We've been building my 4.2 9a1 engine for several years now. Most of these go into Caymans, and a lot of those are PDK. Making 360-375 at the rear wheels for HP, and a solid 300# of torque is very common with these. No issues with the PDK holding that power at all.

We are finishing a 2012 Cayman R now, it made just over 350 RWHP and 307# of torque from a 4.2 9a1 with PDK.

As far as the PDK controller, its a from scratch development that does not use any OEM components. Its being developed as a stand alone for other applications, like coupling into aircooled chassis, and being fitted to aircooled engines.

The Porsche tips are tough. I have yet to see one go bad, and I have 4-5 of them collecting dust, as the market for them is limited, because they don't fail. I build M96/ M97 cars to 4.0, and use the tip tranny a lot. These engines make around 320 at the wheels, with 290 TQ in most cases, and those trannys handle it fine.

Remember, the 996TT used a tip trans, as well as a manual, and these will hold a ton of power as well. I have a turbo tip that I can't hardly give away.
