Let the guessing game begin (going to the track this weekend)
I have been dieing to get to the track with all the changes to the truck. So, let's see who has the best guess on what the new combo will run on it's maiden voyage.
Old combo weighed 3,525 with out the tailgate and made 402rwhp with an unlocked converter (4L80E). Went 11.45@118 (with the verter locked 2nd and 3rd, 115mph unlocked).
New combo weighs 3,300 with the tail gate and now makes 546rwhp through a powerglige. If I can get it to work with out the gate, it will weigh 3,175.
Obviously I have a lot to sort out with the new 4-link, double adjustable rear shocks, different trans, automatic shifter, and trans brake. I have 2 nights to play with it, so what's your guess?

11.45@118 on 402 rwhp impresses the hell outa me. 10.19@130???? what does the winner get?
did the converter change? i missed the thread with all of your upgrades. if you were picking up 3MPH by locking it you can probably pick up more time with the new setup with a converter change.

Well, I am out of gear about 50-100 feet before the line.
Best pass so far:
1.608
6.80 @ 103.58
10.696 @ 119.89
This pass was my first trans brake launch. I did my burn out, staged, got on the 2step (3,500) lights go green and I let off the foot brake but don't move. Uhhh dummy, let go of the button. I lifted a little but stabed it and let go of the button. I let off juat after the 1,000 foot mark.
2nd best pass:
1.647
6.846 @ 103.682
10.71 @ 123.11
