My buddie has that Gtech, and i ran a 13.41 at 108 at the track, and when he lended it to me i was running 13.3-13.4 at 106-108 mph, and my 0-60 was 5.00,4.95,5.10 sec, and i dynoed 311/323 and the gtech read 295hp and 323tq. i tought it was pretty damn acurrate. and a best G of .68 and the shift light and rpm read is great.

Its pretty simple
Force = Mass x Acceleration
it has an "accelerometer" and im sure you have to enter the vehicle weight (mass)
Work = Force x Distance
Power = Work/Time

for what it's worth I'm pretty sure they use the drag strip and road courses. They just use the factory rated horsepower though.

You have to enter the vehicles weight, thats it. They work really well, Ive heard they are more accurate than the racetrack as the accellerometer starts when the car starts moving. The only thing I noticed was the horsepower numbers are a little off.

yeah i bought one a couple years ago and it is right on except the hp is way off. The 1/4 mile time was right on with the mph off like 2 or 3 mph i dont remember now. Overall a pretty neat product.

If you calibrate it correctly, and keep it from moving during your run it can be very accurate. Within 1/10 on your quarter mile times, but it will read a little high on the MPH (it measures instantaneous MPH....your mph at the track is an average over your last 66 feet of your run).

But seriously, I have thought about getting one after I saw some recent T.V. commercials but I was skeptical about the accuracy of the readings.

The MPH is not RWHP or FLywheel HP it is net hp. When I use mine it is 100-120 hp off, b/c of the drag of the car. It explains what net hp is in the manual. The 1/4 time are very accurate though if you set it up correctly.

Car and Driver recently tested a bunch of these. They said the new G-tech is supposed to be pretty good. The magazines use some really expensive equipment that incorporate GPS in their tests. They need to be getting signal from numerous different sattelites for them to measure vehicle performance. The calibration of these less expensive meters usually involves adjusting the meter for how much your car squats during acceleration. Usually the more it squats the more off the meter is going to be unless you calibrate it for your specific vehicle.
