We already featured one video of this mighty Corvette ZR1 from the Battle Creek Speedfest and while this one doesn’t have the impressive multi-camera angles as that original battle with the Porsche GT3, what it does have is some interesting competition in the form of a Buick Grand National.
At the time each of these cars debuted, they were among the fastest cars produced in the United States. The Buick Grand National was the muscle car to have back in the mid-80s. Packing a twin turbo V6 under the hood, the car could run the quarter mile in 14.23 seconds. That was faster than the 1987 Corvette whose specs show the quarter mile time to be 14.5 seconds.
But the Buick Grand National wasn’t up against a 1987 Corvette at the Battle Creek Speedfest. Nope, he gets the King of the Hill C6 Corvette ZR1 with a supercharged 638-hp LS9 V8. Stock, it runs the quarter in 11.7 seconds and has a top speed of 205 mph. But this ZR1 has headers and a muffler delete so you can throw those numbers right out the window.
Here’s the half mile run down the airstrip from the Battle Creek Speedfest:
This wasn’t much of a race, however, that ZR1 does seem take a bit longer to gather itself on the airstrip before the mighty LS9 blows away the Grand National. Maybe in on a quarter mile track or even an eighth-mile track, this Grand National might offer real competition.
One of the commentors on the YouTube video says they were chipped with a top-speed of 147 mph, and wouldn’t you know that’s what this car ran. Not sure if that’s true, but that sounds like 1980’s General Motors: Building fast turbo charged muscle cars with a speed limiters.
This is the second time ever that I’ve mentioned a Buick Grand Sport on this blog. The first was in a blog post earlier today. Weird!
