Just got the car back this weekend. The actual install for the shop said it took 2 days of work. Labor on a whipple stage 2 kit is about $2000 plus added catch cans, oil, coolant and any other shop supplies. I would say if you are looking to modify your new S650 Mustang like this expect about $13,000 bill. Now that the car has a powerful supercharger installed the next mod coming will be lowering springs. I’ll be adding some 360 videos of driving soon.
