To make 914 hp, the Gymkhana 1977 Ford F150 Hoonitruck needs A LOT of air for the turbos feeding the 3.5 L EcoBoost V6. Ford's custom designed manifold ended up being too intricate to cast, so Ford Germany put to use one of the most advanced 3D Printers and even that one was pushing the envelope to get the job done. The result? A high flow, lightweight, 3D printed custom manifold that's the largest 3D printed metal part on a functional car, according to Ford. Watch to see how it was designed and how long it takes to print just one, plus why Ken Block picked a 1977 F150. Follow Ram's Eye The Track Guy on Facebook and Instagram!

A few weeks ago, I made a post explaining mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky
