The LT4, a 650 horsepower supercharged small block V8 found in the sixth-generation Chevrolet Camaro ZL1, C7 Corvette Z06, and Gen. III Cadillac CTS-V, has become a highly coveted crate engine among the aftermarket. This is largely thanks to 650 horsepower out of the box, a tunable ECU, and unbeatable packaging. Take this Chevrolet Colorado ZR2, for example. As if the truck wasn’t already cool enough, Lingenfelter Performance Engineering, with some help from Current Performance, have put together a fire-breathing off-road pickup truck with 534 horsepower and 526 lb-ft of torque to the wheels.
Lingenfelter already offers a supercharger package for the Chevrolet Colorado ZR2, as well as the GMC Canyon, Chevrolet Camaro, and pretty much anything else with GM’s 3.6L high-feature V6 engine. The market-driven package was created to deliver massive horsepower improvements – as much as 500 crank hp – without the massive expenses incurred by a full powertrain swap. But, say you still wanted that sound and firepower of two extra cylinders. Based on the latest video released just yesterday, it looks like Lingenfelter is working on just that.
Under the hood of this special Chevrolet Colorado ZR2 is indeed an LT4, but fitted with Lingenfelter’s LT4 supercharger pulley kit. According to the tuning company’s website, the package costs $1,095 (not counting the powertrain swap, of course), and features an extensive list of modifications, including:
The 720 HP Z06 kit includes virtually all of the required parts other than the engine calibration, including:
– Lingenfelter/ATI LT1/LT4 dry sump torsional vibration damper
– Lingenfelter 9.2 15% overdrive supercharger drive damper pulley
– Pulley fasteners
– Supercharger belt
– 100mm idler kit
– Low restriction air filter
– Crankshaft bolt
– Diagnostic port (DLC) cover kit
– Lingenfelter designed, developed and tested package of components proven to work together
– Engine and chassis dynamometer verified performance
– Engine dyno test results: 720 HP at 6100 RPM, 730 LBS-FT at 3750 RPM @ 13 psi (boost increase of roughly 2.5 psi)
The LT4 and 8-speed transmission swap was said to be done by Current Performance. The price of the actual package for a Chevy Colorado is unknown at this time, but we hope to gather more information soon.
