E85 tuned F80 M3 vs. JB4 tuned F90 M5, 600 whp F82 M4, and 625 whp F80 M3
The camera car in this video is a BMW F80 M3 tuned by @F80Paul on E85 so safe to say the stock turbos are pushed pretty hard. It definitely impresses in its performance though running a JB4 tuned F90 M5 with catless downpipes, a 600 wheel horsepower BMW F82 M4, and 625 whp F80 M3 flash tuned.
The E85 tuned F80 M3 camera car is pretty stout.
The first run against the JB4 tuned F90 M5 the F80 M3 wins easily.
The second run features a 600 whp F82 M4 and the F90 M5. The camera car F80 M3 wins again and the F90 is beaten by both.
The third run is another run against the F90 M5 which the F80 camera car again wins easily.
Last but not least is a F80 M3 said to make 625 whp and the F90 M5 again. The M5 is the slowest of the trio and the camera car again pulls.
Certainly impressive performance for what is said to be an E85 tuned F80 M3 on the stock turbos.
