if i try to launch at 4k or 5k, it doesnt do well, it needs 6k to get everything moving, besides the launch bogs the car down for a second and pulls the RPMs down into the right power band...
Well you might need to launch at 6k because of the way you are launching. It sounds like you just press the throttle enough to get the rpm's up to 6k(NA way of launching), then release the clutch while holding the rpms and then going WOT. If you bounce the rpms 4-5 times, go WOT and then release the clutch at 5k rpms it should just take off since you will be making more boost at that point.
There are many reasons the car gets sideways when launching. The ABS system applies the brakes to the wheel that is spinning more then the others, the front/rear diffs tend to only apply power to one side more then the other and when this happens at the rear of the car it will pitch to one side (usually to the right) which is why I have come to always stage the car toward the left side of the lane I am racing in.
There is always going to be weight transfer and when this happens the fronts are going to lift up till the car settles back down, during that time they will still try to pull the car straight forward.
Plenty of us that have been drag racing and launching quattro cars have been able to do dry launching to warm up the tires before launching hard. I have been doing it for almost 8 years now.
Old video of me launching a B6 with stock torsen
Here is a video of me launching my B5 which also still has all of the stock diff's and the ABS is unplugged. In the 3rd run the rear tires break loose and steps out to the right, sorry its a bit dark during that run.
BTW Jason from JHM has video of him pretty much just spinning all 4 tires all the way thru 1st gear.
