bulldog man Posted October 24, 2007 Share Posted October 24, 2007 To best i can remember : Econodyne was basically the "fuel pincher" or fuel effcient version of the Mack motors Maybe FJH , superdog , HK or Barry could chime in & know something i dont later yall Quote You Cant Fix Stupid.

Freightrain Posted October 24, 2007 Share Posted October 24, 2007 Probably the 237hp version? Where the maxidyne were 285, 300hp?Am I close? Quote Larry 1959 B61 Liv'n Large...................... Charter member of the "MACK PACK" Link to comment Share on other sites More sharing options...
Warpman89 Posted October 24, 2007 Author Share Posted October 24, 2007 Its an E6 350 hp and I wouldn't call it efficient Quote Link to comment Share on other sites More sharing options...
Lmackattack Posted October 24, 2007 Share Posted October 24, 2007 I belive the econodynes had higher HP outputs but lower TQ rateings. they needed more gears to pull you as the power band was up top and not as wide as the maxidynes. I think they came in low rpm models and standard 2100 versions and they claim that they were better on fuel.?trentdsf Quote Link to comment Share on other sites More sharing options...
bulldog man Posted October 24, 2007 Share Posted October 24, 2007 heres a link over towards Hanks truck pictures where they talk bout the Mack motors look under mike malone he talks bout the econodyne & maxidyne , thermodyne motors & i didnt realize they had a board there & now that trent refreshes the memory i belive thats right i belive the TQ Ratings were Lower & hp was higher thats a Screamin jimmy that were called "fuel pinchers" DUH lol Brain fart but i do remember the dealer telling us when we bought a 89 R Model & they came out the econodyne was supposed to be better on fuel than the Maxidyne later Quote You Cant Fix Stupid.
