997 Turbo Cab Construction - Project Not Ours
#46
I have so many updates and things to share! Especially with the tranny Going on vaca today but the crew will be at work. In the meantime, here is a sneak of 1 part of our tranny kit upgrade. These are 1 section of the disks upgraded... Upgraded K3 Kevlar friction discs and high tensile steel plates. Overall we are adding 1 more friction plate that will create more frictional surface area. We are using a 100% Kevlar friction plate. The plates are designed to endure the most severe torque loads.
Other sections and pictures with complete write up on Monday!

Ok here is a good tranny update. The tranny is going back in the car now, but here is how we got to wear we are. Our partner with the tranny is someone that has done some pretty high horsepower DSG type cars and builds these disks. Each disk is drawn up using CAD software and then cut from high strength/temp steel. We then coat each side with kevlar material. From their experience, they put enough spacing between the disks to make sure there is easy engagement.
Here is the initial tear down.
Break out of K1 clutch pack.
Tear down and inspection of K3 Clutch Pack. The K2 clutch pack is one of the primary clutch packs that need upgrading. The friction plates in the K3 unit will be upgraded. There will be more friction plates added to increase the overall surface are of the K3 pack.

Everything together and did test drive. Shifts really precise, no lag. Gonna put about 30 miles on it before we dyno on Tuesday. Here is what we did to the transmission.....
We went with a dual sided disk to keep friction temps down. This way you increase the surface area and run the disks cooler since they are seperated now. First we modify the K2 basket. The factory allowed for 6 friction double sided disks and 5 steel plates which seperated them. The stock is double sided but made out of a weak paper material which burns up easily. The paper material is similar to a 700 grit sandpaper if you will. This is great for operational driving, but not for long term high horsepower cars. The factory disks have only 10thousands of material. To upgrade the disks, we had to program each disk into our computer to be cut from high tensil strength steel. Once the disks were cut, we then bonded 100% kevlar material to each side. The new disks now have 25thousandth of material on each side. This is 2.5 times the material of stock with the addition of 1 more friction plate. So now the K2 basket has 7 total double sided plates and 7 steel plates. 1 being a pusher plate for extra strength. The extra plate is to decrease the distance the disks have to travel to make shifting faster by decreasing the piston travel. As a note, more disks does not equal better strength. The TCU tuning and clamping pressure as well as line pressure is very important.
Next we tackled the K3 basket - The factory allowed 10 single sided friction plates and no steel plates. So basically the OEM is steel plates on one side, and friction on the other. If you can imagine, this is just a sandwhich of plates. Each OEM disk has 10thousandths of material on the 1 side. We upgraded these disks to double sided kevlar increasing the material thickness to 28thousandths. So now we have 4 double sided friction plates and 1 single sided friction plate. There are now 4 steel plate spacer disks in between them. This dropped 1 friction plate but increased material material.

I think the members can answer the before limits of the Tip. The after should be around 900HP.
We are using the GT3076rs .63ar GTX turbos with a 4inch anti surge compressor housing.

Got the car all back together and about to do some testing now. The Vorsteiner VRT kit came out awesome. The modified rear wing to work with the cab looks like it was made for the car. I love the black and carbon accents. We did lower the car with H&R springs and added 18mm rear spacers. Enjoy the glam shots.
Tests results coming soon!
