hi everyone.
i was just wondering if any of you tryed this.
i got one from a guy i work with to try on my trans am.
and i was just wondering how acurette thay are.
i made 5 passes with it.
the first pass i smoked the tires to the rev limeter in first and spun some more in second, and it said i did 14.001 at 109 mph.
the second was almost the same as the frist try, smoking the tires but a bit less in first, and it said 13.751 at 108 mph.
the 3rd was a joke. it was a real good run i came off the line nice and easy hardly spinning the tires got a little rubber in second i reved it to 6000 for every shift and when i was done it said 12.001 at 131 mph.
needless to say i busted out lmao.
and tryed it 2 more times.
the 4th and 5th were 13.510 at 106 mph and 13.54 at 107mph.
my question is do you think that this is close to real Q mile times or not.
it says in the book that thay are as close as it gets.
any comments on wat you think would be great.
thanks ken.

I had a buddy test them against real trap speeds to find as long as they remained perfectly level and solid mounted in the car they were real close. His general consences was it's better for comparisons but reliable enough for loads of fun.

I almost bought one, did the horsepower and torque readings seem accurate?

[Ken. P.]

i havent played with it other then what i did yesterday.
but it dosent messure tourque it messures g's.
inst.G's- cont.G's- 0 to 60- 60 to 0- plus 1/4 mile speed and time.

how much are those things and whered u get e??...i seen a couple vids of a z-71 with one in it lookd like a cool little gadget. also seen another this guy strapped it to his fast gas powerd rc car and hauld balls down a road hit 60mph with that little itty bitty car hehehe.

Last time I checked mine against the track timers it was .06 sec and 4 mph off from my timeslip. It's less accurate if the tires are spinning - I've seen as much as .25 sec. difference.

You must have an old model then, here's what the current one does, scroll down to measurments. http://www.truckxpressions.com/truck...ries/gtech.htm

[Ken. P.]

yes its the older model.
my freind got it off of ebay for 35 dollers cdn.
they put a bunch on there when the new model came out just to get rid of them.

My husband bought me one for Xmas a few years ago. We had our friend take it down the track with him, to test its accuracy. It was almost 2 tenths off and one mile per hour. Close enough, if you ask me.

[Ken. P.]

Thanks for the replyseveryone.
im going to the raceses this week end i was hopeing to try it there but there only 1/8th mile so i'll have to wait till augest to see how it works.
one of the little towns about 4 hrs drive has 1/4 mile drags in aug and im going there to see how it runs.
like i said befor thanks.
ken.

Get a friend to ride in the car with you. It is hard to drive by yourself and keep readjusting them. It is also hard to keep an eye on the tach when you are looking at the G Tech.

There's also a few other brands worth looking at. Escort makes a two models. I bought a tazzo brand a few weeks ago. Haven't had time to play with it much but it should be pretty accurate. It is very important that these things are mounted very solid. Velcro is not good enough. Mine came with some 3M stuff that looks kinda like velcro but it's a lot more solid and it doesn't have any flex. The better models have calibration modes in case it's off by a few percent.
