MED CAMSHAFT TIMING SETUP DISC
( £12.50 EXC VAT )
The outer section of the camshaft sprocket is CNC machined from steel, while the inner section is CNC machined from aerospace 7075 alluminium with the same degree of lightening as our all-alloy timing gear set, including 7075 aluminium clamping washers.
The crankshaft sprocket is CNC machined from steel and now comes with extra deep key way and a full radius machined into the rear of the crankshaft mounting diameter.
This timing gear set will fit any standard A series crankshaft
The timing gear set comes complete with;
Which cam timing setup is best?
The choice comes down to personal preference and usage. As a general rule we'd recommend the following:
Steel/alloy vernier duplex - High mileage road car, trackday and competition, 1.35kg.
All-alloy vernier duplex - Weekend road car, trackday and competition, 0.9kg.
Alloy simplex race - Trackday and competition, 0.65kg.
By nature, the steel outer teeth of the steel/alloy setup are better suited to higher mileage applications. The all-alloy type teeth are machined from a tough 7075 aerospace aluminium and will withstand vigorous use, however, so many are used effectively on the road.
Is lighter better?
The simplex type is aimed at race engines where every last gram matters, but we would not recommend this for regular road use. The lighter the rotating components in a racing engine, the faster it will be able to accelerate to its peak power band high up in the rpm range. On a standard or mildly tuned road car that's less of a concern.
How about the gear or belt drive conversions?
Both have their pros and cons. Geardrive reduces all potential slack associated with budget or worn-out chains, but fitment is a more involved process. The belt drive conversion aims to reduce potentially damaging harmonics in the valve train, but is more expensive. We fit and use all types of cam timing setups in our engines and kits.
