G-Tech Pro 1/4 mile data
I finally got around to playing with my G-Tech Pro today. I don't know how accurate this thing is, but I was careful in calibrating it.
Temp was 76 deg, RH 76%
'01 6-spd sedan, H-box GIAC X v 8 on 94 octane
Milltek superdual
Strat shortshifter
AWE S-flo with Darintake mod
I entered the weight as 3720 with my fat *** and a trunk full 'o ****. I did an aggressive launch, but lifted throttle between shifts.
G-Tech says:
0-60 4.446 sec
1/4 mi 13.015 @ 105.75 MPH
Reaction time 1.184 sec
0-60' 1.820 sec
Do these numbers seem reasonable? How much would Piggies or DP's shave?

The car alone is 3600, so if you include your weight and the trunk full it should be at least 3800
Those #'s do not seem reasonable, and piggies or other dp's would make a nice difference.

I've seen an S4 on the scale that weighed ~3600
with a driver in the car. Only thing missing was the spare. It did have turbo back exhaust and BBS RCs....but that's amazingly light. Driver weighed around 150lbs.

Spare is about 50 lbs, turbo back is another 50 lbs, and 10 lbs per corner for rims=40 lbs.
that means the car weighs about 3600 lbs. totally stock without a driver since the "diet" and the driver equal out eachother. Furthermore, this had the spare and stock rims or else I would expect them to be listed. I guess the superdual would be maybe 20 lbs lighter (guess) so lets say the car even weighs 3575. If he considers himself a "fat ***" and has "trunk full o' ****" it should weigh much more than 3720. He alone weighs more than 145 lbs. based on his description.

I got the base weight from an old Corey S note - he used
3550 sans driver, then I added 170 for me (I'm short).
I think the G-Tech uses the weight only for HP/TQ calculations, but the velocity/time data is directly integrated from the accelerometers.
Looking at the graph it creates, I see I jumped the gun by about .2 seconds.

Well this G-Tech is actually pretty nice...
... finally got around to reading the instructions and loading the Windows software. It comes with a serial cable and AC supply.
Of course, the fine print says it should not be used for absolute measurements but as a before/after tool.
