g tech prob advertised on Speed Channel

I have one but it cost about $200 not $30

 

$200 is the usual number, but I did find this site that says $30 while supply lasts. Very strange.....oh I see, it's an old model, the picture on the other sites is very different.

Yes,works ok, but you're better off with the G-Tech Comp IMO

 

Have one and used it on my 360 for 1/4 mile runs. Works well. A useful toy for car guys.

 

It is a pretty interesting item. I read a comparison test in -I think- Grassroots Mototsports before I bought mine. They made some good comments about it. You have to enter the weight of your car for accuracy which can be a guessing game for some. I did a bunch of 0-60 runs in a highly modified VW Scirocco that I own and the times were all within 0.2 of each other. It was fun finding out how to hit 60 the fastest. In my case it required about a 4000 rpm wheel spin launch. Just pulling away normally didn't get it. It will also map a roadcourse for you and you can go back afterwards and see your times and rpms at different points on the course. I have enjoyed mine.

 

I can't remember which, but either Road & Track or Car & Driver did a pretty thorough test on 8 such devices in the last month or two. See if you can track down that article.

Long and short of it was that G-Tech was pretty accurate for the money.

 

For $30? I don't think you can beat that deal, older model or not. I just bought one.

 

Even cheaper on eBay.

and it works fine but cost about 10 times that. Can't speak for how their instrumentation worked a decade ago but for the price, little to loose I guess. Good luck and have fun.

 

For $30 you really can't go wrong

 

Any recent opinion on GTechPro RR owners ? I am thinking of buying one to get some objective comparisons between cars. I am not that interested in the absolute figures as long as the repeatability is good.

 

This is the unit I have, bought it new way back when. This unit and the ones that follow are not 'cheap' internally, they are quality and quite accurate. Naturally, the results are only as good as the nut behind the wheel following the instructions.

I used mine for 0-60 timing and lateral g's. Also use it for the 1/4-mile timings and, as mentioned above, a little bit of wheel spin in my '95 VW Jetta gave me the quickest times.

The unit is good for performing a baseline, making one change, and running again to see if the one change made a difference. For those who don't have a dyno or test track and do their own work/mods then I would recommend it.

BTW, I used a truck scale to get the weight of my car. Many of them along I-5 and at night they aren't really used, and they're always on.

 

Unless it is a refurbished unit that previously failed.

Yes, the market place where the seller never has to see the buyer and can slide remanufactured obsolete units with no guarantee.
There is a reason why they sell these on Ebay...
