Innovative 2-in-1 Camshaft Gear (with +2° and +4° Offset)
This newly developed camshaft gear offers a fixed offset of both 2 degrees and 4 degrees. Simply turn the gear 180 degrees to switch positions. A smart and cost-effective 2-in-1 design. And the price is even lower than that of a new original camshaft gear. Alongside our popular fully adjustable camshaft gear, we are now introducing this innovative alternative.
Why adjust the camshaft timing?
The crankshaft drives the camshaft via the timing belt. In many classic Porsche 924S and 944 engines, the original camshaft timing is no longer optimal after decades.
Common causes include:
- Resurfaced cylinder head after an overhaul
-
Wear on hydraulic lifters, causing them to respond more slowly
By subtly relocating the keyway in this camshaft gear, you optimize the camshaft's position relative to the gear. This fine adjustment causes the intake valves to open slightly earlier. This results in a direct increase in power.
Proven results on the dyno
Our test measurements show clear differences compared with the original setting:
- +4-degree position: Delivers the most torque up to approximately 5000 rpm. This provides a noticeable 10 Nm increase compared with the original.
- +2-degree position: Also provides a significant torque improvement up to 5000 rpm. Above this engine speed, the +2-degree position comes out ahead, resulting in the highest peak power in horsepower.
Which position will you choose?
- For road use: The +4-degree position is the best choice for extra low-end pulling power.
- For the circuit (racing): The +2-degree position is the best choice for maximum power at high rpm.
The camshaft gear has the original timing marks on both sides. This keeps installing the timing belt simple, regardless of which position you choose.

Installation information
Installation takes approximately 1.5 hours. (approximately 2.5 hours for the 944 Turbo)
During installation, the timing belt must be removed and then correctly tensioned again. This makes it an ideal upgrade to carry out during timing-belt maintenance, cylinder-head work, or other work on the front of the engine.
Have the installation carried out by someone experienced with Porsche 944 timing belts if you are not confident doing it yourself.
Does the timing belt need to be removed?
Yes. The timing belt must be removed and correctly tensioned again after installation.
