Already developing 412 kW (560 hp) from its 5.2-litre V10 engine, Underground Racing applied its Stage 2 Race package, which comprises a pair of custom turbocharger units mounted on the company’s new billet air intake, and RR Plug & Play Motec ECU system with custom E-gear wiring harness. The end result is a stonking 1,150 whp on 93 octane pump petrol and over 1,800 whp on race fuel.
Sensibly, the transmission was upgraded accordingly, with a helix billet differential, a full billet 1-6 custom ratio, billet input/output shafts and billet final drive gears.
We’ve been promised a video of the car in action very soon.
