I came across the following claim:
"Initial testing of the M30 turbo kits reveals that over 400 rear wheel horsepower is achievable from a stock 3.4L M30 motor with the stock engine management system. This compares favorably to an e39 M5 that manages about 325 rear wheel horsepower from its advertised 400hp".
How come we don't hear alot about turbo-charging the 5 series?
A. Is this possible?
B. Is turbo-charging best realized at diesel engines?
C. Is it a Saab and a Volvo thing?
D. Is the M3/M5 our only answers to the Swedish engineers-among others?
Can anyone supply us with some charts to some exclusive BMW mods?
