So I have been reading about the GTECH performance pro meters here and there. Unfortunately, the website sucks and does not have much information. Has anyone used these meters before and have opinions on them?

I have heard complaints about usability but they are supposed to be accurate.

 

They are precise, but not accurate. Basically, if you car actually runs 0 - 60 in 7.0 sec, for example, the Gtech may read 6.9, but it will give you that same repeatable error every time.

Basically, they are not too good for absolute numbers, but they are good for comparing times and speed after mods and such. I ran a 15.35 at the track, while the Gtech said that run was a 15.29.

 

So the Gtech is a performance mod then!!! It cut 0.06 seconds of your 1/4 mile

 

Yep.


Also, when the thing arrives, you will not be impressed with its overall quality. It isnt the sturdiest piece of $140 equipment.

 

Discount Tire Direct was giving them out for FREE with any new set of BFGoodrich a while back. They started the deal like 2 months after I bought a new set of Euro TA... dammit

 

Thats how I got mine. But I did not even buy tires. Just some guy did not want it so he gave me his rebate form. His words were "Why do I want a performance meter when I drive a Ford? Just to depress myself?"

If you read g-techs newer ads.. It says that trap speeds will be higher becuase it gives the actual speed at the 1/4 mile mark while at a track they give you average of the last 60' of the 1/4 mile. I find that to be a wierd statement, is it true?

 

I have a gtech and it's fun to play with but I wouldn't consider it the most accurate thing either. I live in Austin and it's impossible to find a flat road. However, you can use the Gtech forever so if you divide its price over the years of use it's not very expensive at all. I had to buy some replacement suction cups for mine, but they only cost $1.30 for 3
And yes they do average your speed over the last 60'. I guess that's some sort of standard that developed over years of drag racing.

Weird. Never heard of that before. I wonder why it started.

Thanks for the input!

Another qurstion. Is it true that you have to enter your car weight in every time you make a run for different things like switching from 0-60 to HP measurements and every time you turn it on?

That seems like a pain in the butt to me!

 

If you don't want to do a hp measurement then you don't ever enter your car weight. I usually only use the 0-60 and 1/4mi so I don't put in my car's weight.

.06 difference is not so bad for $130...

My ex-gf got me one 3 years ago and I still love it, it fun and not too many people have one.

Hmm, time to get one of these.

 

Dude where the hell do you go to measure 1/4?!?!?! I drove all around this frickin' town looking for a good spot!

 

The G-tech measures the 1/4 for you. You just floor it. It flashes your 0-60 time and when youi get to a 1/4 mile it flashes your ET and speed.

 

I think he means since I'm in Austin where is a flat road. Answer: There isn't one Luckily I'm from Plano which as the name implies is very flat. So if anyone in Austin knows of a flat road it's news to me.

SO the general opinion is to BUY?

 

DAMMIT! My only solution so far is to stop on Mopac somewhere and hit it there... I'd be kinda nervous though stopping on the freeway and messing with the damn thing, getting it zeroed out & triggering it while cars are flying by...

Oh well.

 

Actually the upper deck on 183 just east of Mopac is a great straightaway. We usually do some races up there for highway pulls because it's very hard for cops to see you. Except the time that I jumped to the left lane and flashed my hazards only to see a cop pull up behind me
