<p><span>Road profiles offer a good compromise amongst the daily requirements from an automotive engine: smooth stable idle, good torque at low rpm, low exhaust emissions and substantial max power increase.Racing profiles offer a considerable power increase at high rpm and guarantee performances typical of a competition vehicle. The following are some of the parameters modified to improve the performance of an inte<br />al-combustion engine through new profile camshafts:increased valve lift, increased inlet/exhaust valve overlap and cylinder filling duration.An appropriate profile design having a good mixture of these parameters improves the engine performance with regard to its use.</span></p> <p><span><br /></span></p> <p><span><strong> </strong></span></p><strong>Camshafts codes FAR.104.260S.A (1)<br />FAR.100.272S.S (1) Application Road max Cam lift IN 10.4 Cam lift EX 10.0 Duration 260/272 Timing 5-75 / 60-32 Timing with phase variator opened 30-50 / 60-32 Lobe center angles 125/104 Lobe center angles with phase variator opened 100/104 Valve lift TDC 0.4 / 1.6 Valve lift TDC with phase variator opened 3.4 / 1.6 Clearance Hydraulic tappets </strong>
