brake set up on lower drive shaft

What causes more flexing? A little bit of power? Or jamming a big chunk of ice in between the track and the heat exchanger? If your theory was in any way accurate, then everyone with a turbo would be blowing 2 shafts a week.

LB if Sasquatch said there were no ice chunks why do you find it so hard to believe him. Sasquatch (Charlie) is a VERY large man he is also very honest. Could it be that the combination of torque and additional weight provided the stress necessary to snap the shaft? He has absolutely no reason to lie about any of this so when he say's it broke from natural causes you can believe it.

Weight doesn't affect the driveshaft. Only power applied and there's people putting a LOT more power on it than he is without any problems. I'm not suggesting that he's not honest, just that he's mistaken.

If he has tunnel protectors installed, then there are DEFINITELY ice chunks, no question about it.

LOL LB on his personal vendetta against studs. Ice would stress the whole shaft. The shaft is supported on both ends so chunks of ice would bend the shaft in the middle. Not shear the shaft on the right side only. If failed shafts where bent then you may have a leg to stand on. Seems none are bent!

Also these huge loads you seem to think happen do no damage to the heat exchanger or front bulkhead. I did however check the other end of the drive shaft to see if cracks where forming there from ice chunks. Under UV light no cracks where found anywhere else on the shaft.

Weight does affect the drive shaft because weight increases the load and traction both accelerating and deaccelerating. Turbo power does also effect the driveshaft but only if the power can be put to the snow. Track spin is a loss of power.

The biggest effect on the drive shaft is the constant on, off of the power. The engine braking effect is maybe a downfall of the drive shaft as the ocsilation between forward and reverse twist in mine and others opinions is the cause of the shaft twisting off.

Drive shafts are failing at high mileage. The fact that Turbo sleds are not breaking them at low mileage just shows that it is not an issue that is HP related. Its an issue of twisting the steel back and forth till it breaks. Just like bending a wire back and forth till it becomes brittle and breaks.

This is a time issue of many thousands of twists back and forth that leads to the shaft's failing.

My opinion only others may choose to ignore it if they wish. Someone is asking to move the brake to the shaft and with the number of shafts breaking I suggest for safety sake to look at finding a better shaft. This is the point you are in effect arguing!

Its times like this that you banish all common sense and revert to any argument that justifies your opinion that everyone should not run studs. For someone as smart as you sometimes seem to be. You have these moments. Maybe we all do! Don't take it personal!

It appears there is a shaft designed for a brake on it. It appears it is of stronger quality. As the shaft needed to answer this question has been found any further discusion about breakage should be in a different thread. Feel free to start one if you wish.

With that said lets get back on topic any further discussion should be in a new thread!
