Q: Regarding use of a G Tech

I done some runs today. Weather was cloudy and 52 degrees by overhead.

1/4 mile runs with old style g-tech.

1st run 15.44/93.4
2nd run 15.61/90.4
3rd run 16.39/83.1 (took off spinning)

How far off do you think these #'s are?

Q: Regarding use of a G Tech

Say HemiBeast, I just sold my GTech Pro SS on ebay about a month ago. I am pretty familiar so let me attempt to help you out.

The SS will continue timing until you let off but the last distance measurement is the 1/4 mile mark. Say you hit the 1/4 at 15.0 88mph and continue to 100mph, it would show somthing like 100mph at 19.4. It would all be on your graph. The cool thing is you can time any speed zone you like 45-75 or whatever.

Be sure to calibrate your tach. You can accurately calibrate the SS by going to a track. I believe I ended up using the no.7 front lift and was right on against track slips. The SS will be about 2 mph higher because it measures speed at the end of the track, not the average of the last 60ft.

Remember the road has to be flat and little wind for best accuracy. Have fun. They are a blast.

Q: Regarding use of a G Tech

Well, I got the G Tech today and their
is quite a bit of info to digest in order
to get accurate readings. Read directions
throughly and decided to try it. I know
something was off because my first run
was as follows.

0-60 mph 6.37 seconds
1/4 mile 14.68 @ 93 mph

I know the MPH were off because I
shut down even before I hit 90
according to my speed gauge. I talked
to the tech at G Tech ( He was kind of
a rectum hole) and he said you don't
need to set the initial G rating to
.00 at first. I adjusted the unit by
tilting it until .00 was achieved. He
said you get it close and then launch
and stop. Then go back and it should be
set. The directions in my opinion don't
cover all the finer details of the unit's
operation. So far, one thumbs up for the
ol'e stopwatch method. One thumbs down
for the G Tech.
