You’ve heard the saying “go big or go home” before but no one takes it quite as literally as automotive enthusiast Mike Harrah. Of course there are some extremely large engines out there but nothing we’ve seen has shocked and awed as much as Harrah’s V24-71 Detroit Diesel “Big Mike” engine. This brute of a semi engine is rated at over 3,000hp and makes use of 12 (yes, you read that right) 871 blowers and nitrous to get the job done. (video below)
With a dozen blowers, 36 butterflies, 24 cylinders thanks to two V12 Detroit Diesel engines matted together with splined cranks, and the guts to pull it all together, this engine dynos at an astonishing 3,424hp. It may not be a hot rod or for one, but this engine is a custom builder’s dream! Where do you house an engine like this? Well, you put it in a custom built 359 Peterbilt truck of course.
