Bruiser Conversions is setting a new standard in power for Jeep JKs. With the Cummins 4BT Turbo Diesel Power Plant, Jeep enthusiasts can now boast improved performance in torque, fuel economy and fuel capability, and of course, the cool factor of a diesel engine. In fact, the 4BT engine is capable of producing 400 ftlbs of torque at 1700 rpms. “After several years of intense research with different applications, the reliability, torque and power benefits just made this a no-brainer,” says Jeff Garland, founder of Bruiser and owner of Jeff’s Jeep Yard in Clearwater, FL. With multiple fuel capabilities, the Bruiser 4BT engine can run on several different types of fuel, including waste vegetable oil and bio-diesel. Don Altman, co-owner of Trail Jeeps in Boulder, CO, installs HEMI engines in Jeeps and sought out Garland to provide another source of power to his Jeep clients. “The HEMIs don’t hit full power until the rpm gauge shows 4000 rpm. By that time, catching traction might rip the axles off the jeep in an off-road situation. The ability of the diesel pilot to control the power is like nothing I’ve ever felt off-road,” says Altman.

Some of the benefits of the 4bt conversion in an off road environment.
Torque comes in at a very low rpm enabling excellent control of vehicle with minimal tire spin and excellent traction in an off camber situation caused by added weight. Economy is a plus; in our tests, a correctly modified jeep unlimited can achieve 28 mpg around town and upwards of 30 mpg on the interstate. Depending on build sheet and modifications to engine as well as tire size and gear ratio. Average Unlimited with 37 inch tires and 3.73 to 1 ratio w/ 120 hip and 380 ft. of torque , with automatic Raptor 700r 4 speed over drive will achieve 26 to 27 mpg around town and 30 plus on highway @ 1600 rpms. Multiple fuel capability, the bruiser has the capability to run on several different types of fuel with little or no modifications, such as waste vegetable oil, bio-diesel etc. Read the rest of this entry »
