Just so many variables; tyres, suspension set up, driver, weather conditions, track conditions etc etc.
You can use a "performance calculator" online to give you a very rough idea on performance but then again there are so many variables not taken into account like I've listed above but also including gear ratios, wind resistance, reaction times, fuel load etc etc.

Mine comes out using that calculator like this....
All though doing those times under real world conditions is another matter.
