Supercharged V8-Powered Chevy Colorado Is A Thing Of Beauty

Video / 6 Comments

With well over twice the horsepower of a stock ZR2, this truck ought to be a good time.

GM's supercharged LT4 small-block V8 is one heck of a package. Found in the likes of the C7 Chevrolet Corvette Z06 and the third-generation Cadillac CTS-V, the blown pushrod motor pumps out a hearty 650 horsepower and 650 lb-ft of torque from the factory - enough to propel the C7 Z06 to 60 mph in less than 3 seconds.

So what would happen if you were to, say, drop this potent supercharged V8 into a mid-size off-road truck like the Chevrolet Colorado ZR2? We're not entirely sure yet, but we like where this is going.

The folks at Current Performance have done exactly that, shoehorning GM's 6.2L LT4 powerplant and 8L90-E eight-speed automatic transmission into a Colorado ZR2. After the swap, Lingenfelter Performance Engineering, well-known for their highly regarded GM tuning packages, lent their 720-horsepower LT4 kit to the truck to kick the performance up a notch or two.

The centerpiece of that Lingenfelter kit includes a pulley designed to overdrive the supercharger by 15 percent, yielding an extra 2.5 psi of boost pressure, a low-restriction air filter, engine tune, and myriad other support parts.

The result of all Lingenfelter's fiddling is 534 wheel horsepower on the dynamometer - substantially less than the 720 horsepower this ZR2 theoretically makes at the crank, but of course, different vehicles experience different levels of drivetrain loss, and the truck's big off-road tires aren't doing it any favors on those dyno rollers.

Incredibly, Lingenfelter charges just $1,095 for its 720-hp LT4 pulley kit, which might place it among the best bang-for-your-buck power upgrades out there.

We'd love to see this LT4-powered Chevrolet Colorado ZR2 put through its paces off-road, showing its bonkers desert-running speed on the Baja Peninsula. With two more cylinders than an F-150 Raptor, loads more power, and substantially less weight, we expect nothing short of brilliance.
