I didn’t think the Veryon was nearly that fast. The Super Sport (which is the lighter, 1200hp edition of course, not the normal 1000hp model ) supposedly does it in 9.9s, but I was under the impression that the original model barely cracked into the 10s. On search, it appears that 10.5 is a better number, and yes, even that might be hard for 400hp. So I may have undercut my estimate.
Nevertheless, for The Second Stone, this video is of a pedestrian-looking Mustang running a 9.9s quarter mile, same as the Super Sport. It’s got half the horsepower, no turbos (as opposed to the Veryon’s 4 turbos), and it’s not even running nitrous. Just low weight, lots of tire, proper gearing, and a good drag suspension.
It’s a bit more than a $5000 car, but you raised the bar by citing the Super Sport. You could probably replicate it for less than $15,000. A bit cheaper than the Bugatti for the same straight line performance.
eta: Of course, the Mustang doesn’t have a luxury interior, can’t turn to save it’s life (on slicks and skinnies), isn’t running on DOT legal tires, and is probably geared to top out at 150 mph or so, but there you have it.
