Audi trans axle stronger??

[Aussie Kid]

Hi all.

You may have read that I have damaged the casing etc. of my GT40 trans axle. The Audi trans I have is from a diesel the 3U. Final ratio .64.

Firstly I need one. They are in the 1983 to 1987 Audi's.

Then I have read somewhere - after doing a search - and was wondering what is the upgrade or plate that can be added to strengthen the Audi trans axle.

First things first I'm still looking for a lead on a 3U trans axle.

Any ideas would be appreciated.

Try this ebay seller:

eBay Store - chassis: murcielago, kit car, lamborghini

I got a plate from him, and he milled the tailpiece down make room for the plate.

I should have noticed you are half a world away. You will probably want to find someone a little closer. I would talk to Roaring Forties. They may know someone who can do it.

Thanks for the lead/link.

I'm often in the States, so can soon get the plate direct or have it shipped to friends there.

I chase up the lead/link and get back.

Thanks again.

Hi Bernie,

I haven't been looking since I got back from my holiday, but I have a .igs file for the plate (got it from a forum member).
'
Have you got a casing? Or shall I have another look for one?

Grtz. Bram

Just so people know, the plate I received from ChassisWorks was not a perfect fit. The openings for the gears in the plate were too small and I had to gind them out some. Hopefully they have fixed that since then but I have no way of knowing since they did not respond to my email when I informed them of the issue.

I have a few leads on a trans axle. However if you turn up a casing on a parts box I will buy it.

Thanks

The plate you talk of, is it a strengthening plate for the transmission?

The chassisworks site is hard to access also. Perhaps they are no longer operational.

I surfed around the 'Lamboforum' on the chassisworks link and could not get access to the site here either .

Will keep looking. I have searched this forum as well for anything on improving the strength of the trans axle. - in particular the RF site as they use the Audi trans axles.

Thanks

Hi Bernie,

I found this old thread, titled re 012 but 1/2 way through there is someone selling 016 plates, not sure if they are still active etc.

http://www.gt40s.com/forum/gt40-tec...es/16420-audi-012-box-streangth-weakness.html

RF2 have not really played with 016's much, it's all been 01E's since we arrived on the scene.

I still have 2 people on hold with 016's if you need them.

Regards Paul

I have the Solidwords drawing file of the 016 bearing carrier 'strengthening' plate.

There was also a really detailed webpage (see below) on the install of this plate.

Is this the page you were looking for?

Could you post or email the 016 plate dimensions?
Thanks

Paul,

Thank you for the links.

I very much appreciate the assistance that The New Roaring Forties and RCR have been giving me as an owner of an opposition GT40.

Thanks again.

I have the drawings for the strengthening plate and can make them if anyone wants one. I can also mill the housing if you need that too. Send me a PM for more information.

 

[Aussie Kid]

Thanks for the assistance on the plate and machining.

I have sent you PM's.

Thanks again for your help.

A plate won't strengthen the 016 in high horsepower applications. The end of the pinion shaft is unsupported and with the application of enough torque will cause the shaft to bend and the 5th gear to be damaged.

 

[Cliff Beer]

Scott, so you're saying such a plate is not beneficial at all? Or, only in low horsepower applications? Not too many low horsepower applications in a GT40...

What do you consider high HP? I have two friends that have these in their modified 944's. One is a Magnason supercharged LS1 (650HP 550 Lbs Ft at the rear wheels) he drag races a dozen or so times a year, the other has a 924 with a highly modified Grand National turbocharged v6 (600HP 520 Lbs ft at the rear wheels) he just has fun on the street. Both of these cars have been running like this for a couple of years with the plate without ant transaxle problems. Although they are using 083 version (944 turbo) but 5th gear is identicle to the 016. The difference in the turbo version is in the ring gear diameter and front pinion bearing but the rest of the transaxle is all 016.

I should also mension that the guy that invented this plate builds Diablo replicas in Canada using supercharged Buick V6's and he hasn't broken one since he started using the plate.

Yes I agree as my understanding they are good to assist with mid range horsepower.

I have just 445 HP at the flywheel and this was on the dyno at 4100rpm from memory.

So guess if the plate can handle about 350 - 400 HP this should suffice. I would not be looking at dropping a clutch at 3000rpm +. Guess the wheel spin would handle most.

I cracked the gear carrier cast casing after leaving the bitumen bouncing onto the grass and then bouncing back about 6" down onto the bitumen.

The engine revs went off the dial, as I was thrown around inside.

Once the wheels hit the bitumen the trans axle dropped oil on the spot where the wheels made contact with the bitumen.

I have previously read that the plates were good for the 450 - 500HP. Possibly someone can come in here on specifics..

Thanks everyone I very much appreciate the links and feedback.
