As I pull into the staging area I adjust my torque converter lock up to the lowest setting, chip to the highest setting, turn on my water meth and BD Rad Box , I drop my truck in to 4High and then pull up for until I get my first light then I slowly build boost to around 25 PSI and pull forward until I am fully staged while still maintaining my boost once my light changes I push the accelerator to the floor and wait for the truck to switch to second gear then I switch out of 4High in to 2wd and the rest is history.

I kinda guessed at it today, wasnt the best but it was my first try too. I need to get a dual disk (and limited slip) and master the slipping the clutch while building boost concept

It's a dinky stock/OEM 12mm Rotary VE injection pump with 240k miles on it pushing 6400lbs. 1.75 60' in the above vid (250ish'). It's best is 1.69 with good beach air. Work with me.
 In that run, I'm establishing a baseline with the trans shifting fully automatically. I'm thinking I need to raise the overall shift-points. A later run with shifting manually from second to third (and letting second wind-up a little more), brought the ET down to a 7.99 with a 1.73 60'. (To muddy that results is the fact the quicker run started at about 2200rpm vs 1900rpm in the first  ).Last edited by BC847; 11-25-2011 at 08:14 PM..

I'm trying to hold at least 20ish as the lights come down. Closer to and no more than 25. Any more and I'm having issues of pushing through the brakes.
I would agree with the accusation that, toward GO, the throttle may be on it's way to the floor before the brakes come up occasionally. While I stage shallow, I try to leave around half-way through the third light. This usually results in around a .15 reaction time.

I launch in 4wd at 15 psi, I disengage it in 3rd but I don't think it really comes out.

Youtube search "powerstrokeracer snow white vs ss impala" to see a perfect launch. I'd post the vid or link but I'm on my phone, too much effort.
