AWD burnnout had to do it

[storlied]

I really don't know about that.. I mean I'm not denying it was hella stressful and it might have damaged the vc or even stressed the chain too much.. but I mean.. how often do you hear about the AWD tcase goin out compared to the 4x4 tcase's?

ya i never heard of a awd sytem go out in one the 2nd gens, i would like to know the weak point. Has anyone found the weak point in the awd system?

 

[techieman33]

They die every now and then. The weak point is the viscous coupler. It is able to slip and allow for differences in the speed of the front wheels and back wheels. It's not meant to do this for long though it builds up heat while slippings and seizes up.

could you add a cooler to the TC or does it run with ATF from the trans?

 

[techieman33]

there is no way to add a cooler. The transfer case is "sealed" other than a breather line. It does not share fluid with the transmission, it holds it's own supply (about 1 and a half quarts) of transmission fluid. If it's not abused and gets regular fluid changes there is no reason it shouldn't last the lifetime of the vehicle.

Has anyone ever tried to modify the VC so it's constantly locked? What bad affects could that bring? [if any]

I love it. For some reason I never get tired of burout vids. Cool.
BTW- Steve my last name is spelled with a henson. Thank you for the props!

No worries about the VC.... The actual load on it drops after the tires start to spin. The maximum torque on it happens right before the tires break traction. Once the tires start dealing with dynamic friction (spinning) instead of static friction (rolling), the forces on the drivetrain drop. They see more force during a WOT acceleration than they do when doing a burnout. I wouldn't worry.

Soon to come after next weekend is the race track videos, i am going to be going to rock falls wi and running in the 1/4 mile will see how the truck does. If there is anyone from mn or wi or around that area that would like to go and meet up let me know.
P.S. Hey James i fixed the last name

I was worried about the very beginning when the rear tires started to spin before the front ones, not the rest of the burnout.

That's when it's wear the VC a lot. It doesn't like differences between front and rear driveshaft speeds.

We also have to remember they designed the AWD 5.0L Explorer for some towing. Question is, how much more stress did this put on the tcase than towing in some slippery conditions?

 

[slyfoxexplore]

Sorry i got to add another to how much hp you think it could handle to. I hopeing 10lbs of procharger boost will not be to much for the engine and drive-train to handle.

i have not been on the dyno but according to my g force meter and the ipod touch i am at 420hp as of right now next year this time with the new motor i will be up to 700+
