■ Super Lightweight Duralumin
Duralumin was chosen for its lightweight properties and extra strength and durability. Both the outer and inner part is made from Duralumin to ensure that the product is the strongest available on the market.
■ Precision & Perfection
The pulley and inner plate are made from billet aluminum. The pulley gear part has been designed and manufactured from precision methods to guarantee reliability with securing the drive from the timing belt.
■ Application Specific Design.
The Intake and Exhaust cam pulley have been designed and manufactured individually so as when the pulley comes to the top it is easier to adjust the timing from TDC. (model specific)
■ Ultra Durable.
The hard anodized surface coating greatly increases the durability of the pulley. The added strength will allow the pulley to guarantee reliability for drag racing cars that are running monster power engines that exceed 1,000 HP and used with engine speeds in excess of 10,000 RPM.
■ Performance Use & Showroom Finish
The Duralumin material with the hard anodized surface treatment gives it better operational reliability and will enhance the look of your engine bay for that showroom finish.
■ Simple Scales for Adjustments
A simple scale was designed to help aid tuners anywhere are able to setup the settings on the scale to aid with easy setup process.

Adjustable Cam Gears Assembled   Checking the pistons and camshafts position with dial gauges   Measuring crank angle with a scale board

The simple graph makes it easy to change the engines characteristics with the simple sliding adjustments of the Cam Gear. If the intake valve timing is advanced (i.e. 120° to 110°) then performance gains are achieved at low RPM. If the intake valve timing is retarded (i.e. 110° to 120°) then performance gains are achieved at high RPM. Camshafts with no dowel pin attached will require you to check the timing adjustments with a dial gauge and scale board.


The Poncams valve timing has been preset at 110°. This Valve Timing has been calculated as the best setting for both performance and drivability. You can adjust the engines performance by making adjustments with the cam Gear carefully. This easy adjustable system is a great advantage over other conventional designs.
The engines output character can be changed just by re-adjusting the close timing over the intake valve as shown below.

- Turn Cam Gear to anti-clockwise (advanced timing): torque at low RPM
- Turn Cam Gear to clockwise (delayed timing): torque at high RPM

The standard Valve Timing is set to “0” on the scale. When you adjust the scale to +/- 3 on the scale (3 degrees) that will be +/- 6 degrees on the crank angle. The maximum range is +/- 10 degrees on the Cam Gear which is +/- 20 degrees on the crank angle. Please don’t move the adjustable Cam Gear from zero position until the engine adjustment has been completed. If the cam Gear has been fitted without being setup on the initial key position then the engine wills not opperate normally. If the valve timing has moved too much from the setting due to engine vibrations then the operation of the engine will get worse or in worse case scenario the pistons may hit the valves.
