Cat Cams Renaultsport Clio 197 Cams Now Available

2009-renault-clio-rs-200-02Developing a cam profile for the Clio 197 F4R 830 engine is something of a challenge because the valve to piston clearance is minimal, limiting the extra amount of lift available to extract additional performance.



Designed using unique, in-house developed software, the end result of Cat Cams work is a pair of mild negative radius ‘Sport’ profiles manufactured from bespoke, hollow steel billets and CNC ground to ensure accuracy.


These ‘Sport’ profiles are a direct replacement for the original units as well as being compatible with the Renault factory hydraulic followers and variable valve timing system. Ideally suited to Clio 197 engines using the stock ECU and inlet plenum, Cat Cam’s ‘Sport’ profiles retain decent idle quality and the driveability needed for fast road use.


Cat Cams has also incorporated an adjustable cam position sensor ring on the inlet camshaft, enabling easy timing adjustment without having to alter the cambelt position.

Initial dyno results show that Cat Cams Sport profiles produce a minimum of 5 bhp and 5lb.ft of torque, running in conjunction with the factory inlet and ECU.


The new Clio 197 ‘Sport’ cams carry the part number 5504402. All of the grinds available are listed below.


We also have available the "Slipper Follower" kits that enable these engines to turn up to 9000rpm.
