Advancing or retarding the cam timing is a well known technique used by engine

builders to optimise the power and torque characteristics of any engine. Now Belgian

performance valvetrain specialist Cat Cams is delighted to announce a new addition

to its range of adjustable cam pulleys, for the popular 110bhp TU5JP4 1.6-litre 16-

valve engine used in the popular Citröen C2 VTS and the Peugeot 206.

Cat Cam’s True Lock adjustable cam pulleys offer a number of advantages over the

traditional ‘vernier’ style items offered by rival companies. Primarily they are vastly

more user friendly and accurate than traditional vernier pulleys. That’s because while

rival designs rely on a sliding vernier scale to indicate how much cam advance or

retard has been dialled in, the True Lock pulleys use a unique, fool proof and

considerably easier ‘pin and hole’ system.

The system is simple in operation – around the face of the True Lock pulley is a

series of drilled holes representing one degree of cam advance or retard. Users

simply have to undo the securing bolts, then rotate the two parts of the pulley until

the supplied alignment pin slides into the desired hole. The pulley is then bolted back

together, the locking pin is removed and the user can be confident that the cam

timing is set accurately, without the need to align hard to see vernier scales. And with

plus or minus ten degrees of advance and retard available, there is plenty of scope

for serious adjustment.

Cat Cam’s True Lock pulleys also offer far greater strength than conventional vernier

pulleys, because rather than relying on three easily rounded off allen screws for

securing the two parts of the pulley, the True Lock pulleys use five 8mm bolts to

provide a robust fixing mechanism that’s rigid and secure for very high torque

outputs.

This strength is also reflects on the materials used for the True Lock pulleys – they

are machined from top quality 7075 aluminium billets and the outer cam wheel is

hard anodised to ensure durability.

Existing versions are also available for Peugeot 106 GTi and Citröen Saxo VTS
