The GMC Syclone was the least likely performance car to emerge from turbo era of the late 80s and early 90s. When Car and Driver tested it, the little black sport truck was faster than a Ferrari 348ts, packing 4.3-liters of turbocharged, liquid-intercooled V6 goodness under its hood, making it good for 280 horsepower and 360 lb-ft of torque. The best part about this turbo GM LB4 engine was it still left plenty of meat on the bone for tuners, meaning there are many Syclones running around today with well over 500 horsepower.
Based on how the Syclone in the video below annihilates the C6 Corvette Z06 it’s racing against, we’re going to say it’s good for at least 500 ponies. We’ve never seen a Z06, which has a 505 horsepower 7.0-liter LS7, look so slow in a straight line. Thanks to its all-wheel drive layout the Syclone has the advantage from the start, but by the time the Z06 can take advantage of its mid-range grunt, it’s too late.
Considering how much of a supercar-slayer the bone stock Syclone was in the 90s, this result is hardly surprising. We don’t condone street racing, but this properly insane Syclone was just too good to ignore. Check it out below.
