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. strives to maintain an open forum for reader opinions.
