CAT CAMS camshaft for BMW M3 E36 3.0L 24v 28.6hp S50 B30 engine with vanos intake

Here are our camshafts from Cat Cams for BMW 3.0L 24v 286hp S50 B30 engine with vanos intake

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.

Camshaft profile available for BMW 3.0L 24v 286hp S50 B30 engine with vanos intake 

Rally and circuit profile:

• Cat Cams camshaft reference: 5500122/C /  Opening 0.1mm intake 285°, exhaust 277° / Opening 1.0mm, intake 251°, exhaust 243° / Max lift intake 12.50mm, exhaust 12.00mm / Lift at TDC intake 1.70mm, exhaust 2.90mm / Full opening intake 122° exhaust 108°.

camshafts for use with VVT on the intake (like the original). The VANOS system (VVT) on the intake camshaft changes the valve timing: S50 B30: from 122° to 80° (exhaust: fixed 108°) Data is displayed for full intake lag (VVT disengaged). Check that the distance between the valves and the piston is at least 1mm with the VVT ​​engaged. Improper installation will result in serious engine damage! These cam profiles are suitable for OEM mechanical tappets (37.5 mm) with clearance adjustment shim (33.0 mm) between cam and follower ("shim over" type). However, we recommend using racing followers [réf. CC010] with shim for adjusting the clearance between follower and valve ("shim under" type). This will eliminate the risk of the shims being lifted off the cam follower. Additionally, the increased tappet surface area will allow for more efficient cam profiles. FOR COMPETITION REQUESTS ONLY. The following details should be checked: - The camshafts should turn smoothly in the cylinder head, ensuring free stroke by machining where necessary - The distance between the valve seal and the retainer at full lift should be d 'at least 0.6 mm - A minimum valve spring travel of 1.0 mm at full lift must be provided - distance between valve and piston 1.0 mm (pref. 1.5 mm). check 5-15° before TDC on the exhaust, and after TDC on the intake
