The car rides on a custom tube chassis with a custom independent pushrod suspension and \u00d6hlins coilovers. However the focus point of the car is the huge custom 8-to-1 exhaust headers winding their way through the engine bay. They connect to a naturally aspirated 400 ci LSx V8 that features a Dart LS Next block and capable of 10,000 rpm. Riley hopes to make around 1,000 horsepower with a 16.25:1 compression ratio and methanol fuel. We&#8217;re looking forward to hearing what 10,000 rpm sounds like through those headers.
