Thread: Rhys Millen RM460 Receives Tune and Dyno Run

Rhys Millen's RM460 Receives a Tune and Hits the Dyno

As we've mentioned before, the engine is the 4.6-liter Tau V8 normally found under the hood of a Hyunda Genesis sedan. The Genesis Coupe's rear seat has been tossed to make room, and the V8 has been upgraded with eight individual throttle bodies, a set of JE pistons and an AEM engine management system that all work in concert to bump power to 500 horsepower. In order to make the engine accessible back there, RMR also replaced the trunk lid with a carbon fiber rear hatch that's vented and hinges near the roof line.

Being a SEMA car, there's hardly a bolt or nut on this car that hasn't been modified. The stock transmission was swapped out for a Mendeola five-speed sequential gearbox and the stock suspension augmented by a set of KW coilovers. HRE 560 Series 20-inch wheels, Toyo T1R tires and a StopTech braking system round out the hardware upgrades. The exterior, meanwhile, features an RMR Signature Edition kit with carbon fiber spoilers and custom RM ONYX HD paint job by BASF. The interior sports seats plus alcantara and carbon fiber trim panels from Sparco, and there's a boomin' sound system by Infinity as well.

After viewing the dyno results the Coupe apparently did not live up to the numbers that RMR promised at the SEMA show. Even though the numbers weren't as high as promised I still absolutely fell in love with that V8 Exhaust Note. I feel like with some proper tuning and more time this engine will make some insane horsepower. The fact that this was an entire car overhaul is really what I respect.

What do you guys think?
