Worlds Fastest 'GT4'?

What do you do when you're bored of being one of the fastest 5-cylinder drag cars in the world? Double down and reach for a V10 is the answer Hank Iroz of Iroz Motorsport went with, and we're glad he did!

With world-leading experience gained on the RS3 platform, the switch to the Audi R8 V10 is a similar area for the Iroz team, and with the R8 and Huracan platforms being similar and very active in the drag racing world, it's a great platform to be active with.

It was early days for the car during this interview with a lot of work done but limited testing yet, however, the car was setup with weight balance as a primary focus, and as such the Xona Rotor X5C TR9980 performance turbos were not located out the back as we commonly see, but rather don't he side where some cooling is usually found, and a GT4 chassis was used as the starting point given they are already well caged and come with all the sensors you need, and probably some you don't for drag racing.

With an AMS Performance and Dodson parts package plus a MoTeC electronics system as part of the puzzle, we're interested to see where this project heads in the future.
