Mack econodyne vs maxidyne. Honestly if you look at the horsepower and torque curves for the Maxidyne and Maxicruse there is almost zero difference. Oct 24, 2009 · The Maxidyne engines were a new engineering study by Mack that would yield a "high-torque" rise engine with a much broader power band, much higher torque ratings and the same old dependability and toughness. Maxidyne ENDT engines? (I imagine emissions and maybe four valve heads but just wondering if there's anything else). Building on this extensive background, Mack is now intro- ducing its new Econodyne series engines, which include both Maxidyne and conventional-torque-rise versions. 2 valve or 4 valve head. they had diffrent power bands. RPM range and torque rise is mostly defined by computer parameters. The Econo- dynes are the most fuel-efficient engines Mack has yet pro- duced. Jan 10, 2006 · I think the EM6 is a maxidyne the E6 is set up to use more than 5 speeds, the engines are basicly the same, if you go to mack and buy a basic engine whatever pump, injectors,turbo,intercooler,you can have a 237,285,300,315,350 HP. Maxidyne is set up for vocational and construction use with a wider operating range, while Econodyne is better suited for highway travel. ejliuqz jijk ylc ndub bkzk gczqd hibkqu veqmaqjt eflf ksw
