Firstly tony has measured cr to be 7.43 so surmising it to be higher isnt fair and its also stated to not having 2 bar of boost 4.5 k it was only .65 bar..
If it had 2 bar at 4.5k at 14 degrees and was proven to be 7.6.1 cr then of course karl is correct but i have a logged boost graph that shows .65 bar at 4.5k time and time again??
also what cr is it 7.4 or 7.6 ..
these factors are very important to as why this car has detted..
