Cat Cams Adjustable Cam Pulleys | Renault F4R

Cat Cams adjustable camshaft pulleys for Renault F4R 2.0 Engine

Cat Cams adjustable cam pulleys are designed to allow fine tuning of camshaft timing when mapping an engine. Fine tuning the timing can produce significant differences in engine performance across the RPM range, potentially increasing both power and torque when compared to 'standard' timing.

The design of them lets you advance or retard your camshaft exactly per 1° over a range of +/- 10 cam degrees for easy and secure dyno testing, using the included pin. Moving the pin from hole to hole indexes the pulley 1 cam degree at a time for fast, easy and accurate cam timing adjustment.

They feature:

• made from high quality 7075 T6 aluminium
• the outer wheel is hard anodised for wear and corrosion resistance
• a 5 bolt clamping system (using high tensile M6 bolts),
• a slotted dowel hole to suit Cat Cams camshafts (which provides some additional security from the pulley slipping, and also a reference point for re-timing the engine quickly if removing the pulleys is required)
• an M10 sized central hole and fully flat clamping face (providing the maximum area for the camshaft nut to clamp against)
