awd question

[kjewer1]

Just to provide the info, since I have it, the tcase will hold up. The drishaft rarely fails (I've never heard of it), the rear end rarely fails (never heard of it, just normal wear). If he runs a solid center diff(welded diff, spool, welded VC, etc) there is a greater risk of breaking the tcase and rear axles if there is wheel hop, since much more of the load is placed on the rear suspension (with an open center diff the front tires will spin when the weight transfers to the rear alleviating some of the stress). I would highly suggest he run an open center diff, with a 4 spider upgrade, until he gets the car sorted out. The tranny just needs to be rebuilt by someone like Shep or TRE, with BOTH shafts replaced. In fact the only difference between a "fully built" tranny like what I run (and almost everyone else at this level) and what shep runs in his 8 second car is new shafts. And since I broke both shafts, I had those as well eventually Too bad I sold that pimp ass tranny with 160 miles on it for 1500. LMAO.

So to recap, just have shep do the tranny and tell him what your goals are, and run an open diff for starters. When the suspension is dialed in and he knows how to drive an AWD car with this much power properly, move to a solid diff and stock up on rear axles and tcases.

I'm certain that getting to 600-650 hp is going to be the real problem in this case, not keeping the drivetrain together. One step at a time though, anyone can do it (eventually).

Im more in to rear wheal drive as far as being bullitproof..... i never ownd an AWD car.... and was thinking of purchusing a first gen dsm.... how durable is the drive train?? i heard the 2gen has a better built tranny and drive train... I live in the NYC, there are no strait roads and it snowes pretty good in the winter an AWD wouldnt hurt but how much stress can that transfer cass take?? or how many high rev lounches, will i be able to run 300+ without the drive train givin up on me?? or is the old myth of a chrystler/mitsu tranny that keeps on leakin a thing of the past?

I answered your question one post up. The center diff is by far the weakest link and is the only thing I would bother to replace before it breaks. Speed Design is the one I use, and I think Shep has his own now. They add two more spider gears. I've never broken the spider gears in a 4 spider diff.

SOme pople are making 400-500 whp on stock drivetrains. Its all in how you drive it, and wheelhop will destroy parts faster than you can replace them.
