1 piece driveline

[Autoevo]

I was thinking about installing a 1 piece CF driveline. Has anyone done this on a Suby wagon before?

Nope, but I have been trying to get a few companies to give me a quote, without success.

If you do this, and can keep the retail cost under $600-800, you'll have a lot of interest. Anything to free up the ponies is a good thing.

A one piece alumninum part is a lot cheaper, but the CF design is far better in terms of safety and HP potential.

I am going to start looking around here in my area to see how much it would cost for a CF driveline. I was looking into it a while ago, but now I have the money. :D

Unfortunately it seems if a custom CF driveline would end up being upwards of 1 grand. Does anyone see any drawbacks to a single piece driveline? Possible interference with the exhaust? I am half tempted to pick up a used driveline from the junkyard and have it trimmed down. Maybe that would be cheaper.

You can't have one "trimmed" down. These things spin at ridiculous speeds and are made specifically for the chassis and drivetrain components - tranny + rear diff.

There are no drawbacks to a single-piece driveline except cost...and potentially more vibration through the car.
The only reason to do this mod is to lose the weight which ultimately nets more power at the wheels.

I was going for more HP and i read that CF was a little more vibration resistant. I am not trying to contradict what you are saying but 5 years ago when i worked in a tranny shop we had a driveline custom made from the existing driveline. When they "trimmed" it, they also balanced it. Now with that said it was a truck that this was done on and it was the same DL as what was previously on the vehicle. We were doing a conversion from 2wd to 4wd which required the installation of a transfercase.

If you're balancing it then it should be fine. The major issue is making sure it's not going to come loose - because if it does, or it's unbalanced, it's going to tear the undercarriage up and potentially launch the car in the air, sideways.

A CF unit is better because it will bend, and not shatter or puncture the frame of the car...plus it's lighter and yes, more resistant to vibration while still maintaining high rpms.
