is the Guibo the cause of this???

> and the stories about catastrophic failures that destry the car?

Here's one:

If you Google it you will find similar pics involving Alfas, Mercedes, BMW, and other cars using rubber flex discs. Most owners don't know what that new vibration means, until it's too late.

Too much Nitrous Boost?

yes he should have installed a jet motor
and done away with the drive shaft
it might have been cheeper

How about a rocket? Might use a Jag F1 engine to power the fuel pump.

No nitrous on that car, that's an Accusump, it protects against oil starvation during cornering.

This has a rocket. But it drives the differential.

Any idea how much over stock the engine was putting out and what type of speed was involved to start cutting the car in half like that? Looks like a lot of damage for a car driven on a public street instead of a race course.

What difference does it make how much HP the engine made? When the guibo fails the speed of the car keeps turning the driveshaft, so it makes no difference how much HP the engine made or whether it happens on the street or race course.
A (different) customer here in Texas was driving on a highway when the guibo went, and the flopping driveshaft tore the center support off the body! Such force could easily cut through the sheetmetal of the body, it's just a matter of luck at that point.

Almost definitely a track car to be involving an accusump setup inside the car on top of what looks like a stripped interior. Vandor is right though, power output isn't what caused the carnage, the shaft spinning around disconnected from anything is what caused it. Increased power levels could have caused the guibo to fail faster than usual though.

On another note, many many road cars employ a metal "hoop thingy" that serves no purpose other than to keep the drive shaft from going wherever it pleases should part of it fail. I have to assume pictures like this pushed engineers to come up with that solution.

It makes a big difference if that is damage from pushing it to 150 mph with a boosted engine or from normal street driving at 45 mph. I have had drive shafts fail from bad welds on the tube letting go under heavy loads and usually don't see that type of damage unless your driving something highly modified on a raceway really pushing it or on the street while behaving like the wrong end of the horse really going overboard.

Wanted to dimension things for personal reference and to determine if a few drive shaft safety hoops would be a good consideration on my street car considering the high torque of the Turbo Diesel. The Guibo was eliminated when they mated the drive shaft to the Isuzu transmission yoke.

Nothing to get hot under the collar about.

Yes burning the candle more brightly does cause it to burn out more quickly so more power can an will often lead to shorter service life of components and raises the speed potential increasing the magnitude of damage when the premature failure occurs.

I personally have never experienced a catastrophic failure.... but have experienced the dreaded telltale of hearing a clunk and spotting a black rubber object in my rear-view bouncing down the highway.

Although torque more than horse power can produce a premature failure of a guibo, neither the guibo or its shrapnel cause the damage. The majority of the damage is caused by the forward section of the driveshaft 'stricking' the transmission shifter extension and tunnel. At that point the torque/HP are no longer a factor.... the only thing that matters is the speed at which the driveshaft is rotating - and that of course a factor of the speed at which the car was traveling when the entire unit fails.

The transmission tunnel damage failure in Csaba's link did in fact occur in a race car - but visually the damage was the same on a street car. I know of 2 such failures on average HP street cars while driven on city streets. These examples are of course the extreme - generally a total guibo failure will just knock off the shifter extension before the driveshaft cuts the tunnel... We have sold plenty shifter extensions over the years for just such a repair.

To err on the side of caution is probably best when it comes to these sorts of parts.

What boosted engine? I think you just like to argue for arguments sake, without regard for facts or logic.
Do you not drive over 45? Most of us do.

vendors work hard to find you parts, and you attack them. over 30 years fiat owners have bitched about parts prices, tried to find sources other than the fiat parts vendors...no wonder spiders only sell for about $3000.00 mg,s for $12,000.
now parts prices are at the quality level you deserve. I hope you will be happy when vendors start quitting, and fiat parts guys like Danny who are stuck with parts they can't sell because of the price wars give it up.

Max legal speed limit where I live is 70 mph only on an interstate and most roads are below 45 mph with some State roads at 50 to 60. Have not been on a 150 mph public street yet. The Spider is for a nice ride on a 35 to 55 mph road with some interesting curves in it so it is logical to ask if the damage is from driving the car like you stole it well above what is reasonable or lawful or on a highly modified vehicle run at the edge which the stripped out interior and various tanks and valves in the passenger compartment would appear to indicate about the car pictured in the example posted.

It was mentioned that Guibo failures are gradual and give plenty of warning so those who experience it have ignored the warning for some time however its hard to imagine someone who has invested in modifying a car for track use to ignore those warnings so the failure that was presented as an example more likely was a sudden catastrophic failure possibly from the race modifications that were done and not what you would expect in normal street driving. I did double check mine after seeing the photo presented and found that when the Turbo Diesel was put in that the drive shaft tech eliminated the Guibo as a point of failure.

I take it then that you are not a reasonable person and just a hot head when you respond like this to an honest request for real facts to allow a rational decision to be based upon. My occupation is Root Cause Analysis and asking the Five Why's is SOP for anyone in that business and not a personal affront.

I found that my concerns as mentioned above were taken care of by the people whom the previous owner hired to modify the drive shaft to accommodate the higher torque Turbo Diesel. Whether a better more heavy duty Guibo should have been installed or the rear axle swapped out to one that better matches the output of the Turbo Diesel remains to be seen.

[courtenay]

Some people just can't let things lie....
Give it up, Diesel. Bottom line for me is that a Guibo change after 30 or so years is probably a good idea whether you have a vibration or not - and regardless of whether you regularly drive 45 or 70 mph on a regular basis. If that sucker lets go, no matter how fast you're going or what fuel you're using, the result is not going to be pleasant.
