Driveshaft Safety Loop?

[ViperTony]

For a relatively stock NA Viper, is a driveshaft safety loop recommended or this mainly needed for high HP applications? I've come across this at one my nearby tuner:

this is recommended for higher HP Vipers. I believe it is required if your car is capable of 11 sec or better quarter mile.

That one above looks like the BMR Fabrication piece. Having snapped a drive shaft, I can tell you that having a loop is cheap insurance. The other think I can tell you is that having that loop doesn't guarantee that you won't splatter the underside of the car. I didn't have a splatter happen but if you look at the area protected by the loop, a snap at the rear weld (like what happened on my car) could lead to a big mess. i was quite fortunate. a dual loop is a more solid solution but i don't think any vendors make them.

The BMR Fabrication belly pan and drive shaft loops are very nice. I installed them when at Heffners for the TT upgrade. Great parts

Probably not required for stock HP cars but a nice safety add if you are going for big HP.

Thanks for the advice everyone. I'm still NA and not near any big HP numbers, yet but I will seriously consider this at some point the down road if I go TT or SC this winter.

I put half shaft & drive shaft loops on my near stock '01 just because. I do not race. I just wanted them.

BMR sold me the drive shaft loop without the blingy belly pan for $175. Did not need a large clean spot under the car for $75 more.

Take a look at the pic of the loop and now imagine that the driveshaft breaks towards the rear of the car rather than front. you are still toast.

And your solution to that is?!?

I tightened up the loop on my BMR with a little welding. It is no longer just a large upside down "U", I closed off the bottom so the shaft could not flop around as much if it breaks. I don't know how much better it is, but I hope I don't have to find out.

weld a second loop near the back. simple fix.

A tunnel within a tunnel! Concentrically aligned spirally aligning decreasing radius...

Making the loop as close to the shaft as possible(tight), will help keep it contained.

the only issue w/ the BMR piece is that the loop is soooo far to the front that if the shaft drops, it can still catch things like the frame. if someone has a pic of how they resolved this, i'd love to see one as i'm trying to work it out with mine right now just to be safe.

Its on my ever growing list of mods. Damn car!!!

Here's what I did.........

It will protect the fuel system from going BOOM, but, if it broke at the rear of the shaft it would still flop around quite a bit.

Someone on the board made one that had a tube instead of the loop. I think that would be the best solution. It had a slightly larger ID than the drive shaft and was 4-5 inches long.

 

[grcforce327]

This is the best way to do it!

I might have to get one of those... at least the rear parts!

 

[grcforce327]

Less worry about one of the caps taking out a fuel line!

Protecting the tunnel from a thrashing, broken shaft, especially with aux fuel lines is sure smart. We've seen some catastrophic fires from that cause.

There are some SFI-approved generic CAMARO-FIREBIRD accessory half-shaft-safety loops at $36 ea, use two. Even With MY dinosaur-like skills I found em!

Summit is a wonderful thing...
