Okay I will be rude and share the outcome locally.
MB ML63PerfPack 585bhp
Aero 8 Coupe 390bhp
Aero 8 S2 340bhp
1315bhp.
However I do have a cheat planned. The 5.5L V8 in the MB is known for taking a bit of tuning. A company called DMS in Southampton offers a 720bhp/690LbFt upgrade. Totally unneeded even at 2000+Kgs but what the heck if you are going to be silly you may as well go the whole hog. 1450bhp!
Just think of the petrol.
