Default Launching, etc....

Ok, This Bonneville is my first car with an automatic... usually stick with a manual.

I'd like to take it to the track, and do some quarter mile times, but I'm unsure of how to get the best take offs... Should I turn off Traction Control, and then just stick it in Power shift mode, leave it in Drive, and take off? Or is it best to manually upshift it, waiting for the boost gauge to peak before each shift?

Getting ready to launch.. How do you get it to launch from the peak RPMs? Hold Brake, and press gas, at the same time?

Yeah, all newbie questions.. but put me in a manual, and I drive fine LOL

You should brake torque the car to a desired RPM. You need to practice a bit to see what is best.

Then when it'* time to go, ease in to the gas quickly but not too fast. Once you feel you can nail it to WOT, then go for it.

The object is to minimize wheel spin. A limited slip diferential will help loads as well as drag tires. Also try stiffining the rear suspension so it doesnt compress so much this takes weight off the front tires. Smaller diameter tires will help with 0-60' times.

Sorry to sound so ignorant, but what exactly is brake torqueing? Holding the brake down while pressing on the gas?

Yes, or it is called pre-loading, the car wants to go but is held back by the brakes.
