G-Force meter? best/worst
I want to install a 0-60, 1/4 mile, time, G-meter, gauge. I am wondering if I can get some feedback from some of you as to type, cost, brand, ease of use, memory, where to buy, etc. ??? This is an easy way to compair part changes and launch practice w/o going to the track. Thanks

This is not a dumb question but having pulled 7g in a fighter aircraft is a G meter really any use in a Vette even on the track? I've never even noticed the lateral G even under the most extreme situations in my Vette.

You are probably an exception as every time I push the car hard into a corner I can feel the lateral forces. Plus it would be kinda neat, at least I think so, to see how well the car corners. I dont guess many will see much over 1 g but I would think you could see spikes of over 1.5.

I had a Vericom unit 20 years ago. It worked pretty well and matched up within about 1/10th second to track 1/4 mile times. I thought it was pretty lame, but some of the magazine road tests were even using them instead of real track results.
They are useful in setting up the car and to practice launches and testing new parts. I used mine for time to speed (0 to 60 and 0 to 100) and time to distance (60 ft, 1/8 mile and 1/4 mile). I tried the lateral G function and I didn't find it useful on the street.
I doubt if my brand and model are still available, but a g meter is a useful tool.

I'd used a GTech pro comp for a few years, it was the same as the older GTech RR model except for color. These are the ones that are kind of egg shaped, not the ones that look like an older radar detector. It worked well for me and was nice because I could export my runs to the computer. Seemed reasonably accurate. Sold it when I went to a ChaseCam system.
Also have an old Vericom VC-200 unit, it is huge and ancient, kept it because it has that cool retro look.
Ask in the autocross & roadrace section under general also for some good replies.

Any other types?
Thanks to those of you that read #1- the Question, and replied. I didn't ask for any lateral forces, I guess I should have been more clear. If I wanted to know lateral readings or brag about something I would have. I bet 7g's could be beaten by sliding off a high ocean cliff and reading the peak g's as it hit the rocks below. That is a lateral load also. But I don't need that reading either. Everybody have a great downtime this winter and may you shine in the sun this spring 
. Oh ya, I also looked at Autometer gauges. I would have to remove 1 of the 3 A post gauges then or probably I will just fab up something for what ever gauge drsign system I decide on. I used a lot of force, load, distance, instrumentation, while I was working at GM testing and validating the C5 as well as various other subsystems and compontents. Opps 
, there I go, I bragged too, my bad,

Opps , there I go, I bragged too, my bad, .What do you use the G meter for? Is it a useful aid on the track? In an aicraft it's used to set a turn rate for example. G in an aircraft is radial G ie down through the seat of your pants. G in a car is lateral G or pushing you to the side out of the turn, although I guess you'd get some radial G on an oval. Thats the reason for my question. I've watched the graphics for the F1 cars which hit 4-5G but I can't see the Vette doing more than 1.5G, maybe 2G. As I don't track my car I never experience more than 1G. With a range of 1 to 2G can you adjust the driving on track to get better performance?
As for your time testing and validating the C5 design, I'm sure plenty of us here would be fascinated to hear of your experiences. Sounds like a great theme for a thread.
Hopefully I don't need to resort to the cliff test

G's
G force is read in all directions. If I remember correctly I read that the C5 Z06 could reach 1g lat. on a skid pad, C6 was 1.1 or maybe? 1.2, and the ZR1 1.5 G's. Think of the acceleration G force a top fuel dragster reaches. Thats also braking! I want to compair accel forces under different conditions, tire size and compound, rpm shift points, etc. These meters give 0 to 60, 1/8 mile, 1/4 mile, times and speeds,HP, braking, as well as lateral force. I am guessing that this is done using an internal GPS, time readout, and a force meter. My calibrated A$$ no longer reads like it used to. The crack got bigger with age, the sencitivity is worse, and I just don't trust it as much.

As I pointed out earlier, if you haven't taken a close look at the app "Torque" for the Android base phones, you should if you want one of the best units out there to monitor performance. This VIDEO shows just a little of what all this unit will do.
The unit will record the data and it can be exported to Excel for other post process function if desired. This isn't the best example, but the following is data I collected on a ZR1 Corvette:

Wow
I don't have a phone w/android at this time but was looking to update this past week. I just saw a price drop on the Samsung ll Skyrocket yesterday and the news last night said that new user package prices where were going up Sunday. Sooooo Satuarday will be the day. What size plan GIG does this require. What else, brand, equipment is required for an 01 C5. I am at 455rwhp thru 6spd & 3:90's now but plan to go ProCharger when $$ gets better. Thanks for the unknown info. I will add this to my knowledge bank.

I have a Sprint plan that covers unlimited data, however, this really doesn't matter for measuring your cars performance. The phone, the app Torque and a bluetooth OBDII adapter is all that is needed. The bluetooth OBDII adapter can be had from the internet from some of the popular sites.

I too use the torque pro app in android on a DROID Bionic. Awesome program. Does the race stuff mentioned as well as data-log your car. Was looking at a GTech Pro but then saw there was an app for that. Works well and as shown above records the runs.
Just need the phone, the app, and a Bluetooth adapter. Having a windshield mount helps a lot as well (more like a must).

RaceLogic VBox
I just bought a RaceLogic Performance box - based on one of the car magazines (forget if it was Car & Driver or what) that use them - I did a little research and they seem to be well liked.
There are a couple versions - the more expensive version seems to be used by the "drift" folks a lot.
I got the base one just of the 1/4 and 0-60 stuff.
It also lets you set a course if you want - and then you can display laps to compare them - to see your best worst parts/corners etc.
It has preset menu selection for 0-100-0 or 0-60 or 0-100.
I haven't used it yet car is in the paint shop - but there are plenty of things to find on the web regarding it..
Cheers,
