me and my friends are looking into "splitting" a g tech, but i first want to find out if anyone has one and if they do actually work as good as they say they do. so any feedback would be great.

I think the thing works great if used properly. Comes within 0.2 of actual time. Just remember....you have no tree, so always add about 0.2 to your G-Tech time to take care of reaction time at the track. Unless your that good:cover:

Why would you add time? Your reaction time doesnt affect your ET. It just helps determine whether you win or lose the race.

I had one, thought it was cool. I used it for about a week but then got tired of it, be careful while trying to find out what you pull laterally b/c I almost hit some random ped's....Anyway, it seemed to work well, but I ended up returning it, it's coolness vs. price wasn't worth it in my eyes

G-tech does not allow for tire rollout. Therefore it will "technically" register a little slower ET and about 5% higher trap speed.

The best way to use a G-tech is making at least 2 passes both ways and then averaging the times or the numbers. This accounts for the slope of the road.

the price thing isnt gonna be much of a problem... like i said, we're splitting it among at least 5 guys, so about $30 a person then we'll trade it off and on. cuz we are always putting new stuff in our cars, and that looks a lot cheaper than dynoing it each time. but im glad to hear that it works well so i will end up getting part of one.

edit: how close are the horsepower numbers that it puts out???

Lol...really? That shows how many times i've been to the track.:shrug:

Your RT has everything to do with your total time, so you must take it into account when using a G-tech. I have one, but don't know what I did with it....it's around here somewhere.

Do NOT get a g-tech if the main purpose you want it for is the HP ratings it gives. I have the g-tech Pro and it is pretty cool for 1/4 or 0-60 times. But when you dyno a car the car is sitting there, with the g-tech you obviously have to be moving. and it states in the instruction book that since wind resistance is a HUGE factor your HP readings will be very low. For example i put down about 158 FWHP on a dyno. But the g-tech said i only had ~130 HP. So it is very misleading to say the least. Anyway goodluck with your decision

yea, it said I put out about 130 to the wheels as well.....you say the dyno said 158 WFHP :confused: .....are you sure you don't meen to the wheels because that is um, less than what you started with

FWHP = FRONT Wheel Horse Power

RWHP = REAR Wheel Horse Power

HP = CRANK Horse Power

k, new question here about the horsepower thing...

will the g tech give relative hp gains if used in identical conditions after a mod is added??

hypothetical situation: i take my car to the dyno and get 150 fwhp rating. then i hop on a nice road with the g tech and it kicks out 120 hp. i then put in an exhaust kit that adds 6 hp on the dyno..
then using the g tech in identical wind/road conditions, will the g tech add 6 hp?
