Blah dee Fricken' Blah....
Can't we all just agree that an intake/header/exhaust will step you up a few HP here and there and go back to comparing apendage sizes???

well this is a little off topic but i did a few 1/8th mile runs in my car....i was originally trapping at 68-low 70. then with the K&N CAi i was trapping 70-72 in much hotter and humid temps. so CAI helps

matty-tc the g-tech is fairly accurate (i have a g-tech pro RR) and i get about 135-138 hp readings with 3100 lbs and a stock tc. if i change the weight rating my hp numbers change but when u look at the graph is physically looks exactly the same... so if you were to take the slope at any give point on the graph it would be the same only that the numbers would be different. also the g-tech actually calculates net HP not wheel HP so a dyno would still be technically different because it does not take into account air drag. saying the g-tech is not accurate is not a true statement. if i could measure the exact weight of my tc with me in it then i could calculate accurtate net hp.

I got the K&N in my tC. It's noticably faster. Ignoring the sound entirely, I can tell, and not just mental horsepower. Although I lack the dyno testing abilities, It seems like the best this test can do is estimate horsepower difference. You'd have to do a series of 3 dyno runs before installing and after and compare the averages. Not to mention, K&N has a GUARANTEE that you get more horsepower.

And the GTech is similar in many aspects. But the GTech can provide a more "real world" picture-- it uses basic math: if the car takes X seconds to get to 60mph, and weighs X amount of pounds, the unit can extrapolate how much force was required to move that mass to that speed in that time. That's essentially all a chassis dyno does; is figure out how much force is required to get the rollers moving at X speed in X amount of time.
The GTech has been proven accurate time and again-- to within less than a tenth in the quarter mile. So until you can make a run down the lanes and then guess your ET within a tenth, the GTech will continue to be more accurate than you are. The K&N CAI showed an increase in 0-60 time, with a reasonably accurate real-world indication of increased power numbers at the top. It happens. Welcome to reality.

By using accelerometers, doenst this mean acurracy is gonna be very dependant on proper orientation? (ie. the axis which measures accelleration must be as parallel as possible with the direction the car accelerates). I would think this is crucial to each accelerometer obtainiing an accurate reading in its respective direction.

If you haven't personally used one, then you literally have no idea what you're talking about. I have one, it's dead accurate, and I have no complaints with it whatsoever.
I'd much rather see the "real world" gains of a mod instead of those as shown by a chassis dyno. Dyno numbers are generally poor indicators of a vehicle's actual performance.

My friend has one and it said his civic should run 14's in the 1/4 mile, which isn't what he ran at the track(about a 16.9 if i remeber right)then we did it again and I tapped the g-tech when he shifted and it said he should run 10's. I like them and then again I don't.
