By adding a pair of turbochargers to the Carrera GT’s high-strung V10 engine, 9ff has managed to draw an additional 300hp (224kW) over the standard model. Other changes include new camshafts, less restrictive exhaust manifolds, and a special muffler with a unique valve system and end-pipes. The end result is a final output of 900hp (671kW).
The car was also given a bright red paint scheme with contrasting carbon-fiber accents, and a fully customized bodykit with cut-out front wheel wells.
