AWD Automatic: how to launch?

Post by Onefast2gdsm on Mon Aug 13, 2012 12:06 am

Being I have made the switch from fwd 5 speed to awd automatic, I need to learn how to launch. With my fwd, I had my 2 step setup at 4500rpm with anti lag. I would let the clutch out slow with about 30-40% throttle, let the tires spin a bit and it would grab like a mofo. I know we don't have the option of trans brakes or high stall converters, and the only real option I know to launch an awd automatic dsm is to power brake it. There has to be a better option, as I'm going to be running an hx35 with a stock holset housing that wont see boost until about 4k rpm. That will be a huge problem trying to power brake it at the line, I'll be lucky if i get 5psi out of it. So, I'm making this thread to discuss various ways of launching an automatic. If anyone has any sort of input, please advise.

Power braking is the only way to do it. You just need a high stall converter. You can also use antilag or nitrous, but you still need a loose converter to do it right.

You can do that also, but I think antilag helps get it up on the converter better.

See, i was thinking about antilag, because if I remember correctly (its been a few months) on ecmlink in the 2step/antilag tab there is an option for "disable over x amount of mph" so, if i want to, i SHOULD be able to use antilag WHILE power braking, no? Like i said im new to the automatic side of the dsm world, i can launch a fwd 5 speed easily. I know nothing when it comes to automatics.

Yes you can set up link to have antilag come on while power braking. That is how most of the guys do it now.

Thanks for the help man I really appreciate it! You just made a huge burden come of my shoulders i thought I was pretty much screwed as far as launching with the hx35 without using the bottle.

You are still going to have an issue keeping the car on the line. As you are stalling up the car will push through the foot brake without any hesitation. The guys a english racing have been using vacuum assist pumps to help keep more pressure on the brake while on the line. very simple and very effective.
