Hello together. I was on a performance test stand with my Clio RS (Bj 11/2005) this morning. Now to the procedure: He drives the car on the wheels, puts exhaust air hoses behind the exhaust, sits down and does the test. He says that he did the measurement in 5th gear at 200 km/h. In 5 gears say and write 95KW on the front axle, plus 22KW for transmission, coupling etc. So we come in the end to 117kw(159hps)! Nominal power according to the letter is however 132!!KW(17 9hp)..makes a difference of 15KW (20hp). Super, right? Now the questions to you: – Is the test not normally done in the 4th gear? – Shouldn’t a blower run in front of the engine compartment to feed fresh air to the engine and protect against overheating? Less oxygen means worse combustion, so less power? – Of course I also called Renault and asked what should happen now. Renault requires a second test.. Costs should I take over.. n..is that OK? What happens if I am more than 10% during the second measurement? Will the engine be replaced or what will happen? – How much tolerance does such a dynamometer have? The dynamometer was a Bosch LPS 002. For numerous answers I would be grateful! Greetings,
