Difference In Launching An A4 Vs. An M6???? Ok i know that when launching an M6 car you are shocking the drive train. What exaclty is getting shocked so to say? I guess what i am saying is what does it mean shockign the drive train?
And what about an A4 car.. With no stall? And with a stall and may shift kit, are you shocking the drive train too?
The reason i ask is b/c with an A4 car you can launch on a stock 10 bolt with DRs or slicks with no problem. chrs1313 (a4) pulls 1.3 60s on stock 10 bolt on slicks. And an M6 guy will gernade that 10 bolt..
So what is all involved to make it different??????

If you are dumping the clutch & it hooks you are putting more shock on the drivetrain(rear & Driveshaft) It's just the shock of the dump. On an auto you just kind of hook & glide out of the hole..I guess that's the best i can describe it. Not sure if that helps. That's my theory anyway

They are completely 2 different beast. Just the "hit" from a dump vs a Stalled launch (with exception for a trans brake launch) is just softer. It does put stress on the drive train in a Auto but its not to the degree that a off the limiter hit.
The suspension/tire requirements or when they should be installed changes a good deal. I got away with no suspenion, 10 bolt, 3.23 gears on a small stall, on Nittos for a long time, and the 10 bolt started to whine at 118k but I have seen M6 cars bust rears after a good powershift.
This car came with a 10 bolt, m6 but that has been swapped with a 12 bolt and tru trac, and this trans has managed to kill 2 of them. Do the moth there.
Until you race both, you just wont understand.

I think what you are looking for is:
When an auto launches (sans trans brake) the clutches in the TQ converter slip. This takes the violent forces out of the driveline. You can only smack the gears in the rear-end as hard as the cluches grab in the trans/converter.
On a manual car, on the other hand, the clutch grabs the flywheel much harder. This sends all of the engine TQ though the driveline with a much quicker onset and "shocks" it.
