VS motors in Norway have an M5 with 1033hp & 1091 NM turbo only. No NOS! Has normal interior (except for rollcage) & the driver uses it everyday. So the weight is like that of a normal M5. Much heavier than most other drag racers running 10 seconds.
It runs 9.41 @ 238km/h. Just goes to show that when you modify a car you go into a whole new ball-game. There's also an E30 M3 (4 cylinder) that does 8 seconds turbo only.
