This is kind of ITR Off-Topic, but I wanted to share with my fellow ITR friends the luck I've had using the Gtech Pro meter for benchmarking. I'm building a 90 Si hatch for road racing next year and bought it so I could measure improvements as each mod was completed.

My Type R 1/4mile times with the Gtech have bested high 14.8's, several 14.9's and a couple 15.0's depending on my launch and road conditions of course. All my real 1/4mile times have been in the 14.9's and 15.0's so I'd say it's pretty accurate to real-world driving, even though that was not my intention with getting it.

anyway... here was my post in the EF forum:

I hope this is helpful to others curious about the accuracy and effectivness of the Gtech Pro meter when used to test improvements in mods.

(PS: don't laugh at my choice of header for the Civic, I'm going for low-buck mods here, I got the car for $500 too )

on the gtechk meter i ran a 14.9 but i ran a 13.8 at that track....hmmmm....don't know bout it!! didn't work for me....

 

strange with my old car at one time i ran a 14.1 on a G-tech,later that month i went to the local drag strip an hit alot of 14.2s an two 14.1s,so in my case i guess it was right on,i never had belived that they could be acurate before that, i stll do have my doubts about their accuracy.

 

Interesting.... 2 varying successes with the Gtech. The manual says it is within like .100's of actual times, but even admits it is more likely to be within .10's with real-world conditions. For example, it starts timing you the moment it senses the car start to move, whereas at the track the timing starts once you cross the light.

You also have to make sure the surface you're on is flat, very flat. I was able to pull out 14.2's on a stretch of road that appeared to be flat until I got about a 1/2 mile, looked back, and realized it was more downhill than I thought.

 

I have had a Gtech for about 3 years, I have had it at the dragstrip on numerous occasions. The Gtech was withing .1 of a second on every run, but the mph was higher on the Gtech. I have found that any amount of wheel hope and the Gtech will read inacurately.

If you do it right the GTECH is accurate. It can only be accurate if you read how it works. Its physics. It does read higher traps though because it gives true speed.

 

yeah i forgot to mention that trap speeds were very high
