i run in 4wd the entire way . once i pass the lights i shift back to 2wd.
made probly 30-40 passes this way no problems

 

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

 

I launch in 4h at 10-20 psi but I did launch with it at 40 psi one time and I didnt run any better of a time.

 

40psi launch!?!?! Good recipe for a rapid disassemble if you ask me. Lol.

 

I dont like loseing. LOL

That wasnt a very hard launch

 

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 ).

 

very cool,thanks for posting.
