Default G-tech on my 84

ok I took the car out tonight with a G-Tech. I did a

15.58 @ 89
and
15.56 @ 90

with my 200lbs roomate in the car with me. I dont know how accurate the G-Tech is but thats what it said.

has anyone else used a G-Tech and also gone to the track and found out about how accurate it is?

I also spun for almost a second the road wasnt all that great so with my BFG Drag radials on at the track I think I would do better.

It's all in how you set it up(perfectly level,plumb etc).

I tested it at the track and was off by a few tenths and several MPH, butteh G-Tech will always show a higher MPH due to the fact that it gives terminal speed rather than trap speed.

To use as a tuning tool to gauge improvement, it's not bad, but I wouldn't rely on it for accurate 1/4 mile times.

I haven't tried the newer model which I hear is supposed to be more accurate.

I tried one a week or so ago on mine. No N20 used and I spun thru 1st and half way thru 2nd and she read 14.2 @ 105mph. The last time I went to the strip I ran 13.8's @ like 97mph with no spin and no N20. So I would say that the times are close and the speed is a little high (like Mojo said)

I ran mine at the track, but only once... it was way to distracting to set up and stilll get a good start.

The Gtech was slow by .22 sec and high by 4.5 mph. I've used it a bunch of times though on the backroads.

The ETs from the G-Tech will be SLIGHTLY slow, depending on how you stage at the strip. The G-Tech starts timing when it senses movement. That is consistent with a deep stage. In a shallow stage, you get a "running start" at the starting line clocks. Eliminate your wheel spin. Your G-Tech ETs are close to what you should expect.

RACE ON!!!
