Manhart Racing - BMW Z4 V-10

The German tuner, whose founder Gunther Manhart has 25 years of experience in tweaking BMW engines under his hefty belt, had whittled away the V-10 engine from M5 and M6 into the narrower body of the Z4. With the equivalent of heart transplant for a car, the Z4 is boosted to a zipping 550 hp, and a mind-blowing run from 0-100km/h in just 3.9s. Of course, with such a powerful engine, the original 250km/h speed limit is obliterated.
If you have a Z4 lying around at home that you are dying to get a speedy boost on, hopefully this is an inspiration for a good project to do this year.
