How Do They Measure 0-100 times ??? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I've noticed that the times given in various magazines for an AUII XR6 HP are around 6.7 = 7.2 seconds.

I've regularly tried and done in the very early / mid 6's on quiet, empty country roads.

A few questions -

How do they test this, are you meant to work your way through to 4th gear ? I got my best time in 2nd before going to 3rd.

Sre the times given conservative ?

My car is not modified, standard factory XR6.

Not sure what this has to do with FPV, but the mags usually use a speed sensor, like a Correvit attached to the side of the car.

Which would be far more accurate than what anyone could do with their stopwatch.

Has nothing to do with FPV, I didn't put it in any particular section.

Surely though with someone sitting besides me with a digital stopwatch, there couldn't be a 13 % discrepancy - a whole second ???

Well go line yourself up next to an R8 or T3 & see how you go, personally I think your dreaming, either that or youve got freak of of a car (or watch for that matter).

Let's see if anyone has any constructive comments, or similar experiences.

With a stopwatch there are too many anomalies. big fingers, slow reflex's etc etc. The only true reading would be from a correvit or the like. but that has already been said...

This thread should be in the Pub..

grab a G-Tech for aobut $350 from rarespares.net.au and u can see your true 0-100 , 400m and rear wheel Hp.

Yep
Used a G-tech, or had a loan of one from Jase, when had the xr, cannot really remeber what the 0-100 times where.

Maybe try a search on the forums using g tech as search word

g-techs usually arent accurate, they give a apprioximate figure. With a error rate of +/- .5 of a second i believe.

Snavy, that is way off.

if you are doing a simple 0-100 run it has a real life accuracy +/- 0.01 seconds. The internal accuracy of the unit is even better +/- 0.001. (The real life accuracy if your wondering is the worst cse scenario taking into account temperature, vibration and other elements that affect an accelorometer). ....they are very acurate units for measuing things like 0-100 and 1/4 mile times.

when it comes to horsepower it has a real life accuracy of 3HP. readings however, will be lower on a g tech than on a dyno as the g tech accounts for aerodynamic drag due to the motion of the car.

I have one, and I can vouch for its accuracy...autospeed has also done tests on, and they mentioned how accurate the unit was compared to $10000 equipment.
