RE: G-Techs, How accurate are they?
ORIGINAL: POWERS
I’m asking this question after seeing mention of someone using theirs in the 0-60, 1/4 mile time’s thread. I didn’t want to hijack the thread asking about it so here is a new one.
Does anyone have any experience or have any idea if these things actually work? If so how accurate are they? On their website it says they are pretty accurate but are they for real?
For those that don’t know what I’m talking about here’s a link. G-Tech
If this is close to accurate Id love to get one to see if my mod’s have really done anything, and to see if anything further I do really adds an hp or not.

Heres the link to the Car and Driver story. They tested 4 or 5 of these. Here

The one on eBay may work, may not. Buyer beware... sold as is.

Thanks for that link. I was skeptical before and now I would seriously consider getting the G-Tech Pro RR for $300......seems like the best value.

you can get older g-tech units that look like radar detectors on ebay for like $35...havent tried one out but heck they are cheap enough, might give one a go

RE: G-Techs, How accurate are they?
I'm surprised more folks on here don't have one of these. I got a G-Tech Pro RR, and I haven't even made any mods to my car! I just like gadgets. :')
I haven't had much chance to use it yet. But out of a few tries, the best I could do was 0-60 in 6 seconds, and 216 RWHP. [:'(] This is with an '05 GT stick. I might have been on a slight incline. I estimated my cars weight as 3710 lbs, with me in it, and a Shaker 1000.
I'd be interested in seeing what results others get on a G-Tech, with a stock GT 'Stang.
It WILL read less HP than what a dyno says, due to wind resistance and other factors.
But it's clock is accurate, and 6 seconds for 0-60.... that's a whole second too slow. Is it very difficult to make our cars do 0-60 in 5 seconds? (Manual trans)

RE: G-Techs, How accurate are they?
I tried my old G-Tech Pro again, for 0-60 times. The stock numbers back during last spring/early summer were about 5.5 sec. This is for an 06 GT automatic. Today's times with a C&L intake, SCT xcal 93 octane tune, Corsa X-pipe and mufflers, and the cooler weather here in the northeast (38 degrees)were averaging 4.9! Weather conditions (hot humid vs. cold dense air) have a big effect. Of course, launch technique has a big effect too (need limited or no wheelspin). I go both directions on the same strip of roadway which is fairly level, so that the average would be more accurate. I would love to get some 1/4 mile times, but I can't afford a speeding ticket going over 100 in a 55! Unforntunately, there are no tracks near me.
My G-Tech is one of the older ones I've had for a few years that I got from ebay for about $40. It seems to be very accurate from what others have said, who have taken one to the track. The main things are to make sure the unit is level (the display will show it), the roadway is fairly level, winds are pretty calm, etc.

RE: G-Techs, How accurate are they?
I have one of the G-Tech Pro Competitions (Paid $200 for it at the LA Auto Show about 5 years back) and it's really accurate. I used it at Firebird Raceway on a drag strip with my old Saturn, and it was accurate to 2/10ths of a second for the overall time.
I did notice that I didn't get the same times with my 60' times (off by almost 2 sec), and when I talked with Tesla Electronics (the people who make the G-Tech), they said it was due to the bracket that holds the G-Tech in place shifting slightly. I tightened it down and made some more runs on an 1/8th mi strip and saw the times were off by only 3/10ths of a second for 60' times, 0-60, etc.
They also said that the rollout times affect your 0-60mph times, because if you start it with the 12" rollout, as you'd see at a strip, the time will be less than if you were to start it with no rollout (as much as 5 mph can be gained in that 12", depending on the driver and the car).
And as for those old G-Tech meters that look like a radar detector...Well, they're very limited in what they can tell you compared to the newer ones that have the LCD screens.
They're awesome units, and have been invaluable to me for tuning for my Vette, E-Type, and Saturn. It's given me an idea of not only what the power differences are when I've changed carb settings or intakes, but also when I've made suspension changes, due to the lateral G's readings. Great tool.

RE: G-Techs, How accurate are they?
i only got 1 chance to use my G-tech and it was on a damp road , with a slight incline.
best i got was 14.06 sec at 100.9 mph.
rwhp said 242, which seems kinda low...but then again, it wasnt under ideal conditions
