Was just reading this off the Renault Sport site, about the Renault Sport Cup:
"...New Clio Cup takes the best of the innovations made to the four cylinder 2.0-litre 16V (F4R RS) engine fitted to New Clio Renaultsport 197.
THE ENGINE HAS NOT BEEN MODIFIED INTERNALLY IN ANY WAY FROM THE ONE ON THE PRODUCTION VERSION.
It is sealed at four separate points before being fitted to the car.
Externally the engine differs from the production car with the air box, taken from Clio V6 255. and the mechanical throttle valve unit which replaces the motorised model. The engine and gearbox mountings and specifically-designed.
The exhaust system has also been revised. The '3Y' exhaust manifold has been retained, but the intake catalytic converter has been removed leaving only the main catalytic converter in place. New Clio Cup can however, at no extra cost, be fitted with the optional production silencer limiting engine noise to 85dB.
Combined with the optimised electronic engine management, these modifications yield an increased power output of 205hp at 7,300rpm and torque of 223Nm at 5,550rpm..."
How can they make 205hp (202BHP/151kW), when all they have done is change to the V6 airbox, decat exhaust & a remap?
