Torque Target

John Baxter | August 07, 2011

Navistar’s MaxxForce Big Bore offers higher maximum torque in its multi-torque setup, increasing torque from 1,700 lb. ft. to 1,750, says Tim Shick, director of marketing and field support. Navistar designed this engine with a compacted graphite iron block and cracked-cap connecting rods with its torque peak at 1,000 rpm, thus enhancing its ability to allow the truck to cruise at low rpm.
