I had another 01 M5 a few years back. Sold it only because I got a great deal on it....regretted it ever since. Afterwards the mission for a new car began. I had an 08 Audi S6 v10... Nice but did not have the speed i wanted. Then an 2011 S5... sweet car but Way too small. Had an E60 for a bit, but when the crappy SMG blew, it really put me off of the car. Great engine...bad car...IMO. So I went back to the beast. Still my favorite car to drive. Nothing else like it. Put 4 sets of golf clubs in and do close to 190mph on your way to the golf coarse...it's a beautiful thing.
Finally getting it Close to finished. At least close enough to post a few pics. Still only running 6.5lbs of boost. New pulleys will be in next week, and we should be at 9.5lbs... had to recalibrate for high altitude.
