I know a couple people who have them and say that they are within a couple thousants at the track. They also tell more than just E/T and mph, also braking, HP if you tell it car weight I believe. I hear they're worth it, but from what I've seen, if you tell someone your G-tech time, they say, well, yeah, but what did it run at the track, I say, they can be pretty accurate, but I don't know if people trust them. And a lot of people I know think it's a ricer thing to get, but hey, if you want, get one.

I agree, the G-Tech is worth the money. If nothing else at all, run it when you get to the strip see how accurate it is for your car to establish a baseline. Most of the time I've seen it being within 2 tenths (damn good) and high by a couple mph.

Still, it's an excellent tuning device. You should be able to track your progress.

If somebody belts out a G-Tech time, I'm pretty trusting in it. Problem is you can't scan a timeslip or anything like that to back yourself up.

I have one, and its definatly worth the money. I don't care what people say the thing is damn accurate. It runs 4mph fast on my car usually. I was running 13.2's on it with my ET streets and I went to the track and ripped off a 13.2 first time out.

Its definatly accurate, and is a good tuning tool.

I agree, they are worth the money. Mine is optimistic both in ET and MPH. I ran it at the track back in '99 to test it out. The following runs are:

1.) Track 14.17/ no mph.....G-Tech 13.90/103.2

2.) Track 14.17/96.7........G-Tech 13.91/103.7

3.) Track 14.22/96.7........G-Tech 13.93/103.5

4.) Track 14.24/97.1........G-Tech 13.90/104.7

Though these don't actually agree, they are all consistent. With my G-Tech and with my car, I just add about .3 to the ET and subtract about 6 or 7 MPH from the the trap speed and figure that's about right. Might be that G-Techs differ unit to unit and also may measure some cars performance better than other cars. This is my take on these gizmos anyway. If I had to, I would buy one again.

I have heard that the Gtech doesnt work well with tirespin, maybe thats why the mph is a little higher?

Rev · 02-22-2001, 05:49 PM

The manufacturer (G-Tech) explanation on the trap speeds difference is that the track speeds are an average of 60' before the finish line and the finish line speed. G-Tech claims that their's are actual finish line speeds. They say that this explains the difference.

Computer simulation programs that I have say that there is still quite a bit of difference. The G-Tech is valuable, but is far off in trap speeds. More than what the Tesla people say. Use it as a comparative tool, but don't believe the numbers per se.
