Hello Everyone
Saw a wild Modification you may want for your MD diesel. Fuel stop in Troy, Michigan. I was filling up when a 300SD identical to mine pulled to the other side of the pump. We talked while the tanks filled. He bought the car January 2002, with 300,000 miles on it, and has driven a total of 985 miles since purchase. I can't pronounce or spell his name, he is from India. He did not like the slow - hard start on cold days in Michigan, he also did not like the lack of power from a stop. He fixed both: #1. By adding three batteries to the trunk, bought a helicopter starter and adapted it to fit, he also had a custom flywheel fabricated with wider teeth and tooth contact area, he has a 200 amp alternator to charge the rig. The engine cranks 4000 RPM at start. #2. He has a boost button to engage the starter for an extra blast of power. The engine cranks from Zero RPM too Four thousand RPM in under a second. The kicker is that the boost is limited to five seconds or it pushes the RPM past redline. Note: He blew the oil pump chain and bearings on his first test start, rebuilt and added a high pressure pre oiler, then broke the timing chain on his second start and bought a factory new engine to replace the wreck. If anyone ever hears it crank up, you will know it is not MB stock, it sounds like a double gunshot + a helicopter just beginning to start. Hmmm: #A. Purchase cost of car. #B. New helicopter starter and fabrication time to make it fit. #C. Fabrication and installation of new flywheel. #D. Engine rebuilt once. #E. Purchase and installation of a high pressure electric pre oiler. #F. Purchase and installation of factory new engine. #G. Total of four batteries plus mounting, cables and a bank of heavy duty starter relays to feed the starter 3400 AMPS. #H. Purchase and installation of a 200 AMP alternator. ![]() ![]() ![]() ![]() I don’t think I will try this, it sounds too expensive for my budget…. ![]() ![]() ![]() ![]()
