Alrite.
Please don't stick a flame up my *** for this. For Christmas my parents got me a Gtech Pro. Today I went out the highway and went to a weigh scale (In Alberta there are a few when you leave the city). 2476 lbs., only me in the car. Put it the Gtech and away I went. I hit 118 HP.
Ok, here is the question(as if you don't already know)....
Legit?
I calibraited it on a flat surface. The meter sits in the centre of the car on the windshield(Aligned it with the hazard light). Set it at 0.0. Pulled through the gears. I have a AEM CAI with a magnaflow cat-back. SI (EX in the US) with 5 speed tranny. The car is lowered with H&R Sports. The manual said is should be +/- 3HP. I'll try again tomorrow, hopefully it should be around the same. It is not that cold here, about -10 Cel. Yes, I am Canadian and -10 doesn't feel THAT cold. Some input would help. I know our cars only do 127HP, and who knows what to the wheels.

Rep Power: 0 Imo, I bet it is pretty darn close. I wouldn't think that it is like 10hp off or anything. You are probably making a few extra hp due to the cold temps as well. I don't know for sure of course, but it does seem pretty darn close to what one would expect.
Have you done any 0-60 (not sure what that is in km/h) or 1/4 mile times?

Rep Power: 0 i heard that if you use a gtech to measure hp on a front wheel drive car it wont be that acurate. i dont know if its true though. that what some people are saying.

EDIT: I think I know why that was said... "it delivers Rear Wheel Horsepower" as opposed to flywheel horsepower. I think they are throwing that around as a term to mean WHP.

If anybody is still going to be looking at this thread... I don't think that statement is correct. I heard the same thing though, but it makes no sense at all. Just about everything the G-Tech does is based on an internal accelerometer. I don't think it matters whether you "push" or "pull" on an accelerometer, it all works as long as there is a force on the G-Tech, and that force used with the force of gravity, most likely creates a resistance. This is how it knows distance as well and can compute work done which is then probably calculated into HP. Theoretically it makes sense.
