search all the big owners clubs....they are regarded as the most accurate up this end of the country.....as alot of the other places have been renowned to play with settings for the runs (tyre pressures etc) and hence overread....you wont be able to tell without looking at the specific details set on the RR itself...or running a 100% standard car on there....
Its just iirc when the ZSOC lot went, they had a moan because their argos backbox didnt give them 10bhp extra on the factory standard i rekon
For 99% of people on here they have been the most accurate, and the same for clio197.net/meganesport.net/etc, plus hes now doing all the Jap stuff and has a very good rep with them with regards to outputs!
A 100% standard williams made 150 on RST's iirc, spot on what it left the factory with, even 15yrs down the line, same with some of the 182's/172s.....where as there are a couple on here took theirs to awesomegti and tdi north, and put out high 180's and low 190's with a 100% standard car lol, never been anywhere near true, considering most of the sports always make high 160s when they leave the factory...
Either way rolling roads mean nothing, inlet temps change, atmosphere changes.....its all about power down onto the road, real world driving.....on track, even all this 1/4 mile times are just ghey, if i wanted a quick qtr id buy a 4wd car with silly power.....real world situations ftw
