This is of course an F10 M5 with upgraded turbochargers courtesy of Pure Turbos. Here is the mod list on the 2014 Competition Package M5:
Pure S1 Turbos
Flash + JB4/BCM + Meth
Upgraded DCT Clutch
27psi on 100-octane fuel
The owner plans on hitting the track with this setup as well which likely will result in a new 1/4 mile record as well.
Absolutely incredible numbers from the S63TU platform and the 867 lb-ft of torque is no joke. The race to 900+ whp is on!
