If you haven't followed along with Tuerck's Instagram or regularly scheduled YouTube updates, this Mk5 Supra has been a work in progress for quite some time. Another Ferrari swap of some sort would have been interesting no doubt, but this time around it was something a bit more motorsport-focused. The heart of this new endeavor is a Judd Power GV4 V-10.

Race Heritage

The original version of the 72-degree, 10-cylinder racing engine was introduced in the early '90s and could be seen (and heard) in action over the years in 24 hours of Le Mans, Formula 1, Indy, CART, and even hillclimb competitions. The 4.0-liter, naturally aspirated engine sports 13:1 compression, produces 750 hp, and can be revved out to 11,000 rpm without breaking a sweat. Transmission duties are left to a Holinger Engineering FD6.

Individual throttle bodies are on display for everyone to gawk at, but AEM stepped in to develop a custom carbon plenum that seals the induction area and will offer better control over how incoming air is delivered evenly across all 10 runners. Filtered air will help this engine in terms of longevity, but even with the layer of security, these engines do require a tear down and freshening up every 3-5,000 miles.

In today's automotive world of huge power numbers, many are going to state the obvious: You can make more horsepower by boosting a smaller, cheaper engine. While that's true, the Judd GV4 is a different animal in that its sole purpose is to excel in motorsports and its performance attributes truly shine in action.

Peak horsepower is everything to some, while those that put these marvels to work in competition are far more concerned with real world ability. And put to work is exactly what the goal is, and no, it's not intended to slide around cones. The fruits of the labor involved will be exploited in time attack competition. While the GT4586 was a demo car of sorts and not intended to compete, this Formula Supra build is track-focused.
