Travel back to 1992 and experience one of Corvette’s greatest performance eras. Download this FREE Automobile Magazine PDF and compare the LT1, ZR-1, Callaway Twin Turbo, and Lingenfelter Corvettes that defined C4 performance.
Yesterday we told you about the ASTONISHING 254.76-MPH twin-turbocharged Callaway Corvette. The below video is an excellent presentation of this impressive machine. Reeves Callaway and project manager Tim Good take you on a full tour of the Sledgehammer project. You’ll get to see the Sledgehammer blast the Transportation Research Center in Ohio and even the late John Lingenfelter has a few words to say. Watch this and you WILL be a fan!
What’s amazing, besides the raw speed and power of the car, is that Callaway never built another one, at least, one that we know of. If they did, the owner kept it a secret because I’ve never seen or heard of another Sledgehammer. If you’re reading this and know of one, please let me know. What a difference nine years made between the ‘79 turbocharged L-48 that the Chevrolet engineering department built and what Callaway made. But to be totally fair, Corvette engineers aren’t in the business of developing mega-horsepower Vette engines, and Callaway isn’t in the business of designing mass production cars. . So, we’ll give the Corvette guys a pass and kudos to Callaway! And to think, this wasn’t a trailered speed machine. Callaway’s team drive it to the track, set the record, and drove it home! AMAZING! here’s the story.
