i'm looking forward on buying the gtech estimator.
it is accurate at all?!
check this web out, and they sell it for pretty cheap..
is this the GOOD Pro one, with the .01 accuracy?!

any comments ?!

ive got a prduct alot like it and i like it. it seems very accurate. i use it to help me out on my launches and with my suspension things

 

That is the original type,not the fancy new one. Still a very good price.

 

is it still as accurate?
cause some people say that the 1/4 is pretty good, but they get like 80 rwhp, and stuff like that?

thanks.

 

and you mentioned that it helps you with the launches?
how?!?!

 

i ran 13.5 @ 105.2 at track, g-tech had me running 13.5 @ 109, mph may be a lil off, but 1/4 times are very accurate, as long on flat/smooth road...

cory

 

 

well it breaks down your run 60' 330' 1000' 1/4
and your 0- 10,20,30 and so on to whatever you stop at

i have been practicing different technics on launching my car and using this machine to help me learn what works

 

Actually the one he's looking at does not break things down that far. It will tell you 0-60, 1/4 MPH and 1/4 Time, but that is about all that is useful on the pro (not the competition pro or the newer models). Additionally, once the 1/4 mile readouts start blinking, you won't be able to see your 0-60 time anymore. Also, as eluded to in the thread earlier, the HP and all other functions are so far off it isn't even funny (or useful).

 

all i care about is the 1/4 miles estimator.
would it be pretty accurate on this model?

thanks

 

BTW, do you if i'll be able to get anything else besides 1/4 miles estimator and 0-60, what about the 60 ft. time?
is it possible and accurate on this model..

thanks again..

 

I have one of these, very low end models. It is useful for comparing before and after mods, but I certainly wouldn't go around quoting times from it as proof. It seems pretty accurate on 1/4 mile time (within 1/10th I'd guess), but the MPH is way off -I'd guess it to be 6-7% high.

It measures:
1* 0 to 60 mph time
1* 1/4 mile elapsed time (E.T.)
2* 1/4 mile trap speed
4* Instantaneous lateral acceleration (G s)
4* Sustained lateral acceleration (G s)
3* 60 mph braking distance
3* Instantaneous braking Gs
3* Sustained braking Gs
5* Horsepower

1= Useful, and accurate enough to give a person a good idea of what real times might be. The only thing this low end does well enough to even worry about.

2= Far enough off that you'll wonder how it can be as accurate on the 2 items (see #1) that it is actually accurate on. 6-7 % high, I'd guess.

3= I don't autocross, nor do I care about braking distance unless it's a distance of "not soon enough", but by then it's too late. I'd assume that the 60-0 would be accurate, based upon the 0-60 being acceptable.

4= I still don't autocross. Lateral G's? Who cares? Not me. Want to measure them? Mount the unit sideways -seems pretty cheesy. Might be accurate, but I somehow doubt it.

5= Horsepower. HAHAHAHHAAHHA!
Ahem. What an utterly useless addition. I have no idea how they tested this and found it to be within 5%, let alone 50%. yes it is that far off. And you could test it 10 times down the same stretch, and never get 2 numbers within 25 HP, I'd bet. This measurement is just junk.

Lastly, before I bought one of these again, I'd drive around and try to find a flat, straight road. I mean flat and straight. I live in SE MN, and there is one (seemingly) flat 1/2 mile stretch within 30 miles of my house. 1. And even it may not be flat enough.
Seriously.
It needs to be perfectly flat... and straight.
No.
Even flatter than that road you are thinking of.
Nope, flatter than that road too.

Honestly. Spend the hours upon hours that I have driving around looking for a flat road. You never realise how unflat a road is until you actually need a perfect one. And it can't be curvy either. Flat and straight.

 

youve got a point. you do really honestly need a flat road and its hard to find one. i lucked out and have an unfinished highway near me.

i dont know how much money you are gonna spend but i have the gmeter from passport (the radar people) and it seems pretty accurate with everything.
