The new BMW M3 and M4 have become the darling of the tuning world with lots of shops competing to deliver the most power output possible. This latest M4 project comes from PURE, a California-based company, who gave their project car 708 horsepower at the wheel. Their Stage 2 kit also brings the S55 engine to 707 wtq while using race fuel Octane 100 and methanol.

The mods include their S55 PURE Stage 2 Turbos, BMS JB4 w/ OBD2 cable, BMS Meth Kit, Magnaflow Exhaust, Evolution Racewerks downpipes and BMC drop in filters.

A manual transmission was used in this M4, along with a stock intake system.


With all these upgrades and power, the M4 is likely to run from 0 to 62 mph in less than four seconds.
