I started my design career on the original Viper in early 1989, Callaway was one of the consultants along with Shelby and a few other hot rod genius's. I was lucky to not only meet them, I also worked with them, listening intently to everything they said. At 26 years old I knew I was among hot rodding Royalty. When the video about this car came out he sent a few to the Viper team, I remember watching it in the conference room on VHS. Hennessey is getting 200 out of a new Vette now......Callaway did 254 over THIRTY years ago in a car that did a round trip of dam near 2000 miles to the track and back doing it. THAT is badass!!

It took the rest of the automotive world 20 years to catch up, and even then it would cost you over 1 million dollars to purchase a sports car that could exceed this level of performance. What they achieved with this car was nothing short of astounding. Thank you Callaway Cars Inc. for this archived video. It was a treat to watch and I've quite literally seen every corvette video on youtube.

I was the production manager at Callaway from '87 to '91. I built many of the cars that are still out there today. I drove the Sledgehammer car many times before it went to Ohio. It was a rocket ship. Then, the sales slowed and I got laid-off. One of the best jobs I ever had. Took a callaway car home almost every night.. After it passed my inspection, I gave it to Reeve for his drive home before we let it leave the company. Nothing was compromised.

As a 25 year old young man, I still appreciate the engineering feat that is this car today. I remember doing a English report on this car back in 7th grade and even at that that young of an age, being absolutely impressed and drawn to the level of engineering that went into this vehicle. Every aspect of performance was taken into account, and especially for it's time, was a machine like no other. Purpose built, with no compromise, with nothing left on the table. This is one of the sole reasons that have driven me to pursue a degree in mechanical engineering. Thank you for publishing this video for the public eye. In todays world of electric vehicles (with no soul) and extreme engine efficiency standards this is still, by far, a greater milestone than most any other engineering project to this day. Rest in peace Reeves Callaway, and John Lingenfelter, your legacy on the automotive performance industry has most certainly not been forgotten. Today, I am grateful to be employed at Roush's prototype development division and only hope to be involved in a project of this magnitude one day.

My dream car back then was a C4 Corvette, and the B2K option on the order form would get you the Callaway twin-turbo 'vette. Then there is Sam Posey driving a B2K at Lime Rock, where I used to run EMRA time trials, and the AutoWeek magazine about Sam's drive, which I still have. Then the Car and Driver top-speed shootout, which I devoured whole when it was published. And John Lingenfelter driving his wicked big block Camaro to 216. And the Top Gun Corvette, which was kind of ragged about starting and idling, but dammit, it ran 230 mph.

We did LOTS of turbo, supercharger, nitrous.... U name it. I remember when that car came out. We did some Calloway turbo installations on other cars, but the Calloway Corvette was an option only, you didn't receive a box from UPS for this job, Mr Calloway changed the entire vehicle and dialed everything in before shipping it to the Chevrolet dealership to be passed over to the customer. It would be like sending your riding lawn mower to NASA and it would still be called a lawnmower. In case you didn't notice Calloway didn't splatter tacky stickers & emblems all over the car reviling what's underneath .

The C4 Corvette was arguably the best all-around sports car of the 1980s. It didn't have the rock-solid coachwork of a Porsche, or that car's technical sophistication, but it was faster, handled as well or better, had even better brakes. The C4 is finally getting some recognition these days. Callaways and ZR-1s are currently under-valued, IMO. If I could afford buy one of each, I'd do that right now.

Michael is correct. The C4 corvette beat all the Europeans of the '80s in terms of all around performance. The problem was the cheap build quality but that's to be expected seeing what the end product did cost at the showroom. Europeans had to pick up their game in a big way towards the '90s so as to not be embarrassed by the Corvette and also by the Honda NSX. The C4 Vette and the NSX did us all a big favor because all sports cars eventually became better because of those two pioneers.

why is only john the "driver" when he was behind the HP in the car? I love callaway but they are not about the core "motor" but all that surrounds it. Great video but lets be honest. Look at all the 80's and early 90's. WHO was winning all the road & track, car & driver unlimited comparisons? John Lingenfelter did by A LOT . Why isnt john given more credit throughout the years ? I would love to see the evidence that Callaway built the motor on this without john's imput or design. Look at the callaway twin turbo vettes. they were great for sure, but bolting on some turbos and making barely over 15hp over a stock zr1 in 1990 is not a lot for the price tag ( minus arrow and other tweaks) add cat back and you got your 15hp on a stock zr1. if this is true about the sledgehammer, why hasnt callaway in current day added " much more " hp on current day callaways? Seriously. Its like when lamborrghini did the "reventon" and made it look space ship and fighter pilot interior and did NOTHING for the HP, how can you justify charging 3 million more ? so it was so technologically advanced with the gauges and body it cost 1.1 million over a stock LP 640. Here is a quote, " almost all the mechanical elements, including the engine, are sourced directly from the Murciélago LP 640" . MSRP for a LP 640 was $450k and in dealer mark up and uniqueness around 400k. so 600k more? LMAO Now its worth roughly $2.5 million. ego buy . (dont tell me investment)
