Michael Harrah’s 24 Cylinder, 1704ci, 12 GMC Supercharged, Nitrous-Injected Truck Engine


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.
