most of them are not sites, they come from the le mans annuals. from 2011 on, they're from here (unless otherwise noted):

some older ones also come from different archived .pdf files from the time of those races.

So it is about which calibration you trust most.
At Le Mans at the moment the hybrid cars are in lift and coast at the speed trap so we don't see their top speeds.

yes, as far as hybrids go, the speed traps don't tell the whole truth, although over the course of 24 hours, they come somewhat closer to the real speeds than in the practice/quali sessions. anyway, that's why, for the hybrids, i noted the highest speed i've seen on the onboard telemetry, where it was available, if it was higher than the highest trap speed on the aco data.
by the way, when did aco have the speed trap at the wrong place and where was it placed?
sam, do you happen to have any of that data still available (your own measurements from different years and the measurements of the teams that you mention)?

i have got 2005, 2006 and 2007:
2005 gt1 race top speeds:
aston martin dbr9: 302 km/h (both cars)
ferrari 550 maranello (larbre & cirtek): 301 km/h (290 km/h & 289 km/h for the bms ferraris)
corvette: 294 km/h & 290 km/h
ferrari 575 gtc (jmb): 290 km/h
for comparison, the 2005 playstation audi r8 went 318 km/h, the champion ones 310 km/h, the pescarolos 325 km/h.
2006 gt1 race top speeds:
aston martin dbr9: 305 km/h & 301 km/h
aston martin dbr9 (russian age): 305 km/h
corvette (alphand): 305 km/h
ferrari 550 maranello (covers menX & russian age): 304 km/h
corvette (corvette racing): 304 km/h & 300 km/h
ferrari 550 maranello (larbre): 301 km/h
lamborghini murcielago (jloc): 299 km/h
saleen s7-r (acemco): 297 km/h
aston martin dbr9 (bms): 291 km/h
2007 gt1 race top speeds:
saleen s7-r (oreca): 304 km/h & 297 km/h
aston martin dbr9 (larbre): 302 km/h
corvette (alphand): 301 km/h & 297 km/h
aston martin dbr9 (amr): 300 km/h (both cars)
corvette (corvette racing): 299 km/h & 298 km/h
corvette (psi): 298 km/h
aston martin dbr9 (bms): 297 km/h
ferrari 550 maranello (convers menX): 295 km/h
if i remember correctly, the late '90s/early 2000s gt1/gts cars were as fast as you say on the straights. the old vipers used to top at over 310 km/h i think.
