Default Driveshaft failure

In my years of racing, and giving vehicles a hard time I have never had a driveshaft fail, but it only needs to happen once and cause injury....!

So this is what I have done from the strength of parts point of view, and of course a regular check for wear and tear is very important. Buy good quality U/Joints, and as big as possible I used 1350 series, with a Mark Williams machined yoke for my Jerico, and I also purchased top quality weld on driveshaft parts etc, including the U bolt 8.8" differential pinion hub to cope with these large style U/joints. The driveshaft is only going to be well under 2' long, so I will fit a hoop made out of 1/8" strap, about 2" wide securely attached probably top and bottom, quite frankly you can make your hoop out of 1/4" or bigger but its a waste of time and excessive weight if it isnt supported properly, and quite close to the driveshaft tube, so in event of failure the least angle the better!

Also the requirement here is to have the Hoop more to the front of the driveshaft according to the certification guy, but that may depend on where the seats are!

I agree with you wholeheartedly, but I looked at it and because of the position of the battery I think it would be hard to get the power away from the fuel lines, or do you mean just close to the driveshaft? Are most battery cables not close to the fuel lines on cobras?

It does seem dangerous to me, kind of like a woman, snackhouse is way too close to the outhouse...bad design.

I have my fuel lines running down the left side of the chassis & the positive battery cable running down the right side, just makes me feel better keeping them apart.

Great thread on driveshaft loops, I'm in the process of getting one for mine!

For some reason I thought my setup was unique, turns out that this is the standard routing of the lines for fuel and power on SPF's. I have EFI so I have higher pressure and a return line, but thats the only difference from stock. I am waiting for this driveshaft armour cover discussed above to be finished before I look at rerouting the lines... they probably shouldn't be that close to each other anyway, but if I can mitigate the risk by spending some money for the cover then I will just do that. I know if I start to reroute I will screw something else up... I alway do.. my wife tells me so..

Sounds like a plan to me. Since its standard on SPF's, shouldn't be a problem if you can shield from any driveshaft mishaps that may occur. Let us know what you decide.

PS - Love the color of your Cobra! When I looked in your gallery, it was as if I were looking at mine! I even have the gloss black rollbar.
