That’s right, Mike Harrah’s show truck engine has 24 cylinders and 12—count ’em—12 GMC superchargers! It’s as far out there as we’ve ever seen, and we love it!
Why? “Because I can,” Harrah says. There’s no reason to take a 24V71 and build an intake manifold that weighs 1,000 pounds and mounts eight 6-71 superchargers on top of four others other than to say: There, take that. Yes, this is a V24 Detroit Diesel two-stroke (normally used to power ships), which is two V12 Detroits joined together nose to nose with splined cranks. It adds up to 1,704 ci. It’s ridiculous, on a grand scale. And that’s why it’s cool.
