GTech Pro RR Performance Meter..
Thursday, October 19th, 2006I finally got one of these GTech Meters the other day, and I have to say i am quite impressed with it so far. This thing is supposed to use some accellerometers and some crazy math to tell you some things about your vehicle- Such as, Horsepower, Torque, 1/4 mile times, Handling G Force, 0-60 times and a few other goodies. It also has some features great for all of you all that race. if you drag race, it tells you your 60ft times and has a built in tach with shiftlights that brighten as you get closer to redline. If you road race, the Gtech Pro RR can record your run to be later uploaded to a laptop to look at the forces acting upon your car. The Gtech will record up to 2 hours of data.
The only complaint i have with the Pro RR is in calibrating it. It is a pain in the neck to calibrate. Once done though, let the fun begin.
I’ve never taken my Denali to the drag strip, and certainly have never autocrossed it, but i threw the Gtech in it anyways because all our project cars are in some state of work. I know what kind of power my truck is supposed to make, and i know within 2/10s what i should run in the 1/4. The Gtech was 1hp shy of what i think it should be and 4 ft lbs heavy on what i thought. Quarter mile times as told by my Gtech Pro were within a tenth of what i should run if i go to the strip. While these numbers may not be exact, i believe that they are close enough for a good idea of what your mods may or may not gain you. For the cost, I dont think it can be beat, sure, you could spend the money on a few trips to your local dyno, but why not have something that tells you what you want to know when you want it?
Thats my thoughts, if anyone else has any on it, id love to hear them, leave me a comment.
