Night at Drags 13.0 @ 108.42mph
Well I went to the drags, thought i was ready, but i was experiencing bog down on Shift from 1-2.
Now let me say this, i am still not prepared to flat change with close to 400hp at flywheel.
Stading start i have down pat, but it do a slow gear changes as i do not want to shock my drivetrain.
results.
R/T 1.273
60' 2.271
660' 8.543
660 mph 88.51
et 13.016
mph 108.42
Every time i changed into second, engine bogged down for 0.5 - 1 sec.
I friend has the run on video and it is clear to see the car slows down on the 1-2 change.
So I have to solve this with out having to flat change.
my car will definately run 12's once this is fixed, or I decide not to be gentle on the car.
No NOS.
No Boost controller or other electronic gadgets
just 100% GIAC Tuned ECU for GT turbo.

Lucas, hook up a Vag to it and collect some data while doing your run next time.
Do you have a wide band O2 sensor and display that you can replace the primary sensor with to see what the mixture is like in near real time?

i get some kind of hesitation too shifting 1-2 on my MY99,
like something's slipping or is adjusting (timing correction probably) but i seem to have lost that after i changed my clutch. my diagnosis skills suck =)

congrats, thats some trap speed :)
what do you mean when you say "flat change"?
must be some "aussie" term
im shure you've already done it, but i noticed my 1-2 shift became much smoother/easier after i chenged out the tranny fluid with some royal purple.......
