The Coolest Part Of Ken Block's Hoonitruck Isn't What You'd Expect

Video / Comments

That big intake popping through the hood isn't exactly stock.

"Custom" doesn't even begin to describe the work that goes in to making Ken Block's rides. The extensively modified vehicles drift their way across our screens as some of the most unique vehicles ever constructed. And that goes double for the Hoonitruck.

The pickup that Block drove in the latest Gymkhana Ten bares what could be described as a passing resemblance to the '77 Ford F-150 on which it's loosely based (and on which Ken first learned to drive). And perhaps the greatest modifications were made under the hood – or in this case, popping out of it.

Instead of the straight-six or V8 engines with which the sixth-gen F-Series came stock, the Hoonitruck packs the 3.5-liter twin-turbo EcoBoost V6 from the Ford GT. But Ford Performance and the Hoonigan Racing Division didn't simply drop the engine in (if you could call the swap-job "simple") and leave it at that. No, they upgraded it from the 647 horsepower it kicks out in the mid-engined supercar to deliver over 900 horses. And that meant feeding it with more air.

Without the right intake manifold available off the shelf, Ford Performance made one from scratch.

It took a full work week and a considerable amount of computing power to complete. But when they were done, the custom intake manifold protruding from the hood (and partially obscuring Block's view) emerged as the largest 3D-printed metal car part ever made.

That's really saying something, considering the speed at which 3D printing is picking up across the industry – especially in low-volume, high-performance machinery. Both Ford (for the new Shelby GT500) and Bugatti (for the Chiron) are using "additive production" to make brakes. And Koenigsegg is 3D-printing entire turbochargers. But none of that compares in size to the Hoonitruck's intake.
