Absolutely. Totally agree.
However you have to decide if you want your field to include unedited Kunos cars. If so then the Audi R18 is a good bench mark. If it can't better 3.30 around Lemans2017 then the Pescarolos shouldn't do that either. Around 3.34-3.35 is where their best laps should be. Any faster then you are most likely looking at either what you said. The incorrect weight or an unrealistic torque curve/boost setting with not enough transmission power loss.
