Here are our camshafts from Cat Cams for RENAULT Alpine R-1223 1.4L 8V engine 840.725
Description :
The Cat Cams camshaft will allow you to considerably increase the performance of your vehicle.
When a vehicle must receive extensive mechanical preparation to obtain results worthy of the name and above all a significant range of progression, work on the camshafts becomes inevitable.
When preparing the Cat Cams camshaft, two modifications are observed: the valve lift and the opening angle.
Valve lift allows you to change the length and opening angle, which causes less or more air to enter the combustion chamber.
You should know that more air entering therefore modifies the air/fuel mixture in the cylinders, which increases power at high revs.
Also, the greater the opening angle of the valve, the more the air flow increases, which promotes the air/fuel mixture and therefore more power.
Therefore for use in competition, leisure, circuit and other, the revs will be sharper, the character of your engine will be more furious and thus you will benefit from a better range of use which will become a real asset.
Without broaching the subject of driving pleasure which will increase your sensations tenfold.
