Went out today at lunch in search of the lonliest stretch of highway within close reach of work. I know they say g-techs MPH high, but I didn't expect this:
1st run- 15.10 @99.6 MPH (?!)
2nd run- 15.30 @98.4 MPH

This is my totally stock '00 5-speed SE, full tank, car full of everyday items, engine 30 min of driving hot. Was trying to launch fairly gently at 28-2900 RPM, still a lot 'o spin & some hop. Hit rev limiter @ 1-2 on 2nd run. 3rd run was cancelled due to circling cops. Anyone with other g-tech results/input?

Congrats, you have stock Max that can do a low 14's (possibly 13's).

Those MPH results are WAY off.

i gotta question, do the g-tech meters work? would you trust them up to a point, and do you use them?

haha thanks for the info. and do you just plug it in or is there other install options.

G tech is an accelerometer. It measures your acceleration calculates your 0-60, 1/4, etc.

They are pretty precise... do some runs on a stretch of road, install a mod and do more runs on the same stretch of road. I'll use it only for that because it's not really that accurate. CalsonicSE used my G-tech and got a 1 second difference (0-60) going up and down the same street (different directions).

You just plug it into a your 12V adapter to power it. I believe their site is http://www.gtechpro.com

I had a GTech Pro for a while. The ET's were pretty close to what I got on the track. The MPH was off a little though. Forget about the HP reading. LOL.

like Kev said, they are precise, but not very accurate... good for gauging the effectiveness of mods...

The other day my GTech said " 14.56 @ 105 mph "...

I wouldn't trust g-tech for anything...

my friend's Z32 showed 13.90 once though (in a 12sec car) with a 4.9 0-60sec


I borrowed his, did a lap in my CRX with street tires, came back with 1.08 lateral constant G-forces.

I don't trust it.

Thanks for the input guys, the whole g-tech deal was about what I expected. An interesting note: when I went back for run 2, there were two straight, even, 15-20 foot black stripes on the pavement from run 1. With no LSD! Makes you wonder!

I did a little testing with my G-Tech yesterday and got:
0-60 = 6.22{full tank of gas}
1/4 = 14.8 94mph.

I think the thing is pretty accurate, the key is to do your tests on a flat level surface, any bumps will screw the thing up.


BTW my I30{when SC and all} got the following #'s
0-60 = 5.44
1/4 14.28 @ 107MPH. The trap does seem a bit to high on that run but I did have massive wheelspin{as always}.

Yea make sure you use a very level surface, since an incline will make the GTECH think that your car is creating all the positive G force (going up hill, tilts the GTECH up) therefore making it think you've completed 0-60 and 1/4 in a very short amount of time, case in point, my 1991 honda accord lightly modded going i went 60 in 7.1 secs, thats wayyyyyy too fast, that 91 accord with intake could never do that unless I was spraying, and after I hit 60, I slowed down and the road started to go down hill, and the GTECH started measuring 60-0, the hill was fairly steep, and for the hell of it i slammed my brakes, initiating ABS and all, and at about 38 mph, the GTECH stopped, and said my 60-0 was 98 feet, THATS UNBELIEVEABLE TIME FOR A SEDAN , LET ALONE A PORSCHE!

i can't get mine to work right. all kinds of crazy numbers. at least i hope they're wrong. my 0-60 times average ~9 sec. i know i've got an auto, but it can't be that slow.

Paul6speed

Thanks for your summary of Kevin's response Nauman. I don't think I would understand Kevin with it.
