last week you guys asked about a test using a stock birfield against a super birfield. well we did one using Bobby's axle testing machine, and we made a video! The first test using a stock birfield broke the birfield at 7,000 ft lbs of pressure. #2 test test with the super birf ended with the inner axle breaking at just over 10,000 ft lbs! If you wanna see this video give bobby a call and he said he'd send a few to you guys!

Any chance of making this Video in download'able form?

We were gonna do that and put it on the website, but n either one of us is any good with a computer! so it's not gonna happen!

I'll convert it if you want to send it to me.

What is the address for the website?? I tried toyota superaxles.com but got nothing.. I'm interested and would like to check it out..
Thanks:D

Here ya go....

Can you at least please post the test criteria? :confused: I'm concerned mainly in what angle the joint was tested at.

thanks,

Yeah, angle is my primary concern as well.

I should also mention that Marlin Crawler performed this test on his joints as well, with similar results. But in the end, his joints didn't fare so well. :(

Do the video with the birf at full turn, and again at half, and again at straight. That should make everybody happy... and then I'm sure you can find someone on here who can convert the file into an MPEG format or something.

I would like to see the video you do have, and have the capability to transform it as well. PM me if interested.

The test performed on the birfields was set at 35 degrees. We figured testing them at full tilt would be the best way to do it. Early tests on these were done with the axles straight.The results are the same. Were running out of inner axles and growing weary of breaking perfectly good stock birfields!
