LSI Posted January 20, 2013 Share Posted January 20, 2013 Whats the sweet spot on a 2013 505 hp MP8? Quote Link to comment https://www.bigmacktrucks.com/topic/29525-sweet-spot/ Share on other sites More sharing options...
Mackpro Posted January 20, 2013 Share Posted January 20, 2013 I think they have 3 versions of the MP-8 E, M and C and that new super low rpm engine (1100 rpm at cruising speed)) they have been talking about. And I think all of them have different sweet spots, From what I've seen they all have good power and MPG regardless of how they are setup. However getting them spec'ed just right can really squeeze some high MPG numbers out of them.

MackMann85 Posted January 21, 2013 Share Posted January 21, 2013 1350-1450 cruise rpm is a good rule of thumb across the board for these engines, move around within that range depending on the application Quote Link to comment https://www.bigmacktrucks.com/topic/29525-sweet-spot/#findComment-158931 Share on other sites More sharing options...
cxn613 Posted January 31, 2013 Share Posted January 31, 2013 Our 2008 with mp-8 lights up two $$ signs in the center display to let you know ur in the sweet spot.
