4.5 is actually the SLOWEST 0-60 number I've read for a 6GT3. Usually the consensus seems to be around 4.0-4.3 from CD, RT, AW and MT. I think Top Gear's test of 6GT3 is close to 4 flat if I remember correctly.

I think that dynos not calibrated correctly. Sorry.
Porsche engines make quoted power pretty much on the nail from the runs I've seen in the UK. The only times they surpassed is with remaps etc. Its nice to kid ourselves, but that is what it is. Still beats audi/ferrari etc who massively overquote lol....

My runs on a Dynamics dyno showed 323 rwhp. Corrected by 15% gives 380 hp exactly.
My very limited experience with others running on Mustang dynos shows very optimistic numbers. Nonetheless, these dyno runs are only good to show what mods do for your car. In fact, what mods do for your car with pulls immediately after one another, no mod to mod. As you note, this does give you a baseline.

4th gear in these car's are actually suppose to be the correct gear to do a dyno pull in, so tons of info said on 6speed and my shop who worked on my 996tt who dyno'd my car...
Great numbers!

There are giant differences between dynos. Just research it. Mustang is VERY optimistic. Dyno Dynamics is known as being VERY true.
Any given Dyno can really only be used as a baseline for that car, on that dyno on that day. For example, if you are trying to determin the effect of mods.
I dont own a 911 anymore (went back to an NSX), but I can tell you that my NSX dynoed at 325rwhp at Comptechs site (Dyno Dynamics) the day the supercharger was installed and then a bit later dynoed at 360rwhp on a Mustang dyno at another shop. Only a difference of a few months. Same altitude, temps, etc. So there is a giant variance (not even considering calibration issues).

FWIW, both both DD and Mustang are eddy current load dynos - and both are regarded as providing close to real world numbers assuming proper load-setting the dyno for runs. In fact, Dynojet has also recently offered a loading dyno. IMO, most reputable shops can properly load-set on a Mustang or DD, and the results (for either dyno) do not end up "VERY optimistic."
