Chevy Colorado ZR2 gets LT4 swap as 720 hp mini monster truck

Let’s say someone wished a major-bore desert- or dune-running truck with OEM bona fides in a additional compact bundle than the Ford F-150 Raptor or coming Ram Rebel TRX. What’s a person to do? Chevrolet doesn’t provide a truck in the Raptor class, but all the items are there, so a person operator labored with Lingenfelter Overall performance Engineering and Current Overall performance to set people items alongside one another. Starting with a Chevy Colorado ZR2, Current Overall performance put in a supercharged six.2-liter LT4 V8 typically found in urban firecrackers like the C7 Corvette Z06 and Cadillac CTS-V. On prime of that, Lingenfelter fitted its LT4 supercharger up grade kit, with tools like a new supercharger travel belt, loafer pulley, nine.2-inch travel damper pulley that overspins the supercharger by 15{0764260a27b4b31ca71a8adf79c3ae299a61e6f062052eee3f0df84ce9b30ade}, Environmentally friendly Air filter, and NGK spark plugs. The end result is that as a substitute of the 650 horsepower and 650 pound-feet of torque found in the standard engine, the upgraded motor generates 720 hp and 730 lb-ft.

The Colorado arrives with a selection of two engines from the factory, either a 3.six-liter V6 rated at 308 hp and 275 lb-ft, or a 2.8-liter Duramax diesel with 181 hp and 369 lb-ft. Lingenfelter helps make a supercharger kit for the 3.six-liter that cranks output to 450 hp, plainly not ample for this operator. A dyno operate with the LT4-swapped Colorado in 2WD manner and shifting by way of the retuned 8-pace transmission confirmed 534 hp and 526-lb-ft at the rear wheels. Even with the Colorado’s beefy mechanicals and bigger-than-stock wheels taking in up around 25{0764260a27b4b31ca71a8adf79c3ae299a61e6f062052eee3f0df84ce9b30ade} of power and torque, the pickup spits additional hearth at the wheels than any of the present-day experience vans muster at the engine.

The overhaul wouldn’t have arrive low-cost, even though. A base Colorado ZR2 rings up $forty four,490, a new supercharged LT4 crate engine adds $15,000, the Lingenfelter 720-hp supercharger kit another $1,095 on prime. That’s a full of $sixty,585 before alternatives on the truck, peripherals for the engine, labor, people shiny System wheels, the chunky rubber, and that tingly exhaust. It truly is also $five,475 outside of a base F-150 Raptor, but we consider the actual comparison with the Ford requirements to transpire out on the trail.
