It's fun to be able to post some of the cool things we are working on here at Pfadt. This week we have been conducting final durability testing on our long anticipated carbon fiber driveshaft.

This little video shows the cycle testing we are doing. The torque we are cycling to is 1350 lb-ft. That is past the failure point of the factory aluminum shaft. Remember, that shaft sees engine torque only, not multiplied torque from the gear box. How much torque does your engine make? We have over 10,000 cycles to 1350 lb-ft on this shaft so far. I'm pretty sure the hydraulic ram is going to fail first

One of the interesting things is that the aluminum driveshaft has about 2x as much twist at the same load as our carbon shaft. Not surprising exactly, but interesting to see anyhow.

Here are some photos of a 'beta' unit being installed in a C6Z.

Note the weight of the stock assembly versus the Pfadt assembly

This is 4lb 10 oz lighter. All of the savings is rotating mass also.

This beauty replaces the rubber 'guibo'. Guess which one is stronger

This shows the whole assembly before it is installed in the torque tube.

Coming very soon!

Just wanted to give everyone a quick update on the testing of the Pfadt Carbon Fiber Driveshaft! At the end of the day yesterday the Carbon Fiber Driveshaft has taken 507,724 hits successfully!

I was thinking about that number last night and decided to try and get some perspective. How large is 507,724 really?

Here is what I came up with:

Corvette use:

"Unofficial" drag races on daily commute
3 x (3 shifts) x (5 work days/week) = 45 cycles/week
Weekend at the local drag strip
7 x (4 shifts + 1 burn out) = 35 cycles/week
Random smack down on blue oval products
2/month x (2 shifts, doesn't take much) = 4 cycles/month

Cycles/Month = 324
Cycles/Year = 3,888

So to reach 507,724 it would take 130 years and 7 months!

What's the routine on your Corvette?
How many Mustangs do you embarrass each week?
How many shifts during a weekend at your favorite road course?
What about your favorite on-ramp on your way home from work?
How long would it take you to reach 507,724?

wow those are pretty impressive numbers! im sure alot of people will want to get their hands on this!

Impressive numbers and a sweet looking mod! :sm_party:
