Most of the time metrics are not collected at a sanctioned track - they are collected whereever the opportunity presents. And the timings are tracked with a unit called a VBOX. I can't remember the technical details, but C&D had quite an interesting article detailing the testing equipment several years back. From what I recall, the unit was very accurate - accurate for figures like ET and g's. However, this is a guess here, I would imagine the trap speed figures would be "optimistic" - much like a gtech.

But that's just a guess.
Yea... if that's what they're doing, they might as well be using a stopwatch as far as I'm concerned. I mean how hard is it to use a legit track for that kind of testing. I know the mags used to use Pomona in SoCal all the time.
Anyway..... I would be interested in reading that article because years ago I put a gtech in a Mustang that was running high 11s at the time on slicks. A guy that was marketing them gave me one to try out. I figured the sudden launch of dumping the cluch with slicks was just too much for the thing to deal with because the results were not even close to accurate.
I wouldn't doubt that that type of equipment is better now but I would have to see identical numbers repeated on a track with real timers to confirm before I'll believe what amounts to a g-meter/calculator can 'figure' down to 1/10s of sec/mph with repeatable accuracy.
Maybe someone with real life experience of doing that can chime in.

Anyway...... real 106s are being produced and what I'm really interested in seeing are some real track numbers from one with the new long intake and exhaust combinations. If the Stillen intake with pullys and HFC makes as much power on the track as claimed on the dyno I think we'll be seeing some 108s (or more) that won't be debatable.
