RFCDrum Posted June 4, 2013 Share Posted June 4, 2013 My 676 283 hp will pull all day with the 6 speed. Your not going to break any land speed records but the low end torque is there all the time.

GearheadGrrrl Posted June 4, 2013 Share Posted June 4, 2013 Until Volvo took over, Mack conservatively rated their engines power- for example, the 2004-2006 Maxidyne E7 at it's highest rating was rated as 370 HP, but that was at governed speed- it actually put out 405 HP at a more usable 1600 or so RPM. And yes, they did pull that well- I've driven 237s that ran with the competitors 300s and 285 and 300 horse Macks that ran with the competitors 350s. And the E9... Nothing could touch it!
